Roller chain and sprockets is a very efficient method of power transmission compared to (friction-drive) belts, with far less frictional loss. Although chains can be made stronger than belts, their greater mass increases drive train inertia. Drive chains are most often made of metal, while belts are often rubber, plastic, urethane, or other substances. Drive belts can slip unless they have teeth, which means that the output side may not rotate at a precise speed, and some work gets lost to the friction of the belt as it bends around the pulleys.

An electric motor made by Brown, Boveri & Co. from Baden powered the engines in the factory, transmitting the energy via a complicated arrangement of shafts and drive belts in the factory workshops. These were later replaced during the 1930s with individually powered machines.

A vehicle is deemed eliminated once its header section is destroyed or the combine is immobilized. Competitors attempt to use the header to pop other vehicle's tires, rupture their drive belts, or tear off their header.Palahniuk p.41 The competitions can end in ties if the only remaining machines become inextricably tangled together.

The Beisel was a cyclecar manufactured in Monroe, Michigan, by the Beisel Motorette Company in 1914. The Beisel used a four-cylinder water-cooled Prugh 1.5L engine and had a friction transmission connected to the rear wheels by drive belts. The wheelbase was , and had a track width of . The Beisel cost $385.

A placard indicating this requirement is located on the CAT indicator and in the Pilot's Operating Handbook (POH). Power is transmitted from the engine to the drive system through drive belts. Originally, the R22 used four separate v-belts running on multi-groove sheaves. This system proved problematic, as individual belts would sometimes roll over in their groove and fail.

Timing belts, toothed belts, cogged or cog belts,in Contact !, Experimental Aircraft and Powerplant Newsforum for Designers and Builders, n°55, Dieselis Aircraft, A Prototype Aircraft with a Diesel Engine and synchronous belts are non-slipping mechanical drive belts. They are made as flexible belts with teeth moulded onto their inner surface. The belts run over matching toothed pulleys or sprockets.

Most punch presses today are hydraulically powered. Older machines, however, have mechanically driven rams, meaning the power to the ram is provided by a heavy, constantly rotating flywheel. The flywheel drives the ram using a Pitman arm. In the 19th century, the flywheels were powered by leather drive belts attached to line shafting, which in turn ran to a steam plant.

The front suspension was changed from a transverse leaf spring to MacPherson struts with torsion springs and an antiroll bar. The DAF 66 was introduced as a successor to the 55. It featured new, boxy styling of the front, and a new rear axle design. The two drive belts now powered a differential, and the axle was changed from a swingaxle design to a leaf sprung de Dion axle.

Rasmus Winther's widow, Christiane Benedicte Winther née Ottesen took over the operations after her husband's death and ran the company until her own death in 1831. The company was then passed on to Rasmus Roulund (1806-1870), the son of the founder's daughter. His son, Peter Roulund (1839-1915), started a production of drive belts in 1872. The company was converted into a limited company (aktieselskab) in 19303.

This system uses a metal belt and has an effectively unlimited number of gears, switching between them without noticeable shocks. These metal drive belts are the most important part of CVT. There are three factories producing these belts, the Bosch factories in Tilburg the Netherlands, Ho Chi Minh City Vietnam, and San Luis Potosí, Mexico. It is used in over 40 car models, even in expensive brands like Mercedes-Benz.

Rubber drive belts and rollers hardened with age, causing malfunctions. Faults such as these damaged the tape irreversibly, a particular problem with irreplaceable tapes filmed by users. VHS tapes recorded in LP or EP/SLP mode were more sensitive to minor head misalignment over time or from machine to machine. Tapes recorded on a machine made before 1995 tend to not play well on newer machines due to slight changes in helical scanning head design.

In automobiles, a 42-volt electrical system was an electrical power standard proposed in the late 1990s. It was intended to allow more powerful electrically-driven accessories, and lighter automobile wiring harnesses. Electric motors were proposed to be used for power steering or other systems, providing more compact installations and eliminating the weight of drive belts or large wires for high-current loads. The proposed new standard was exactly triple the voltage of existing "12 volt" systems.

The engine's design concentrated on the reduction of moving parts. The cooling fan and dynamo were built integrally with the one-piece crankshaft, removing the need for drive belts. The use of gaskets, seen as another potential weak point for failure and leaks, was also kept to a minimum. The cylinder heads are mated to the cylinder barrels by lapped joints with extremely fine tolerances, as are the two halves of the crankcase and other surface-to-surface joints.

Fan drive belts overstressed fan bearing housings in the crankcase leading to cracking. Reliability did improve over time with modifications and improvement programmes, such as the "Sundance" programme which also improved power output. Sundance was carried out in five main phases between 1976 and 1979. Sundance had been preceded by "Dark Morn", "High Noon", and the initial "Fleetfoot" engine development programme -the person responsible for the choosing of code names apparently being an admirer of the Western film.

The modern CVT works according to the same principle of split pulleys allowing infinitely variable gear ratios. Rather than the pulled rubber drive belts as originally used by DAF, the modern transmission is made more durable by the use of steel link belts that are pushed by their pulleys. This improvement was pioneered by Fiat, Ford and Van Doorne in the Netherlands from the late 1970s. "Gearless transmission - steel pulleys make it automatic" Popular Science, July 1976, pp. 57.

At introduction, the engine enjoyed considerable technological advancement compared with its competition, most notably being the lightest and shortest V6 in its class. It has fully automatically tensioned drive belts and adaptive Siemens EMS2000 engine management. The fuelling and ignition timing are constantly varied to match the load on the engine to improve refinement. The engine boasts Variable Geometry Induction, whereby air induction pipe lengths vary to optimise engine torque in response to different engine and road speeds, aiding refinement and efficiency.

Extremely overloaded top-loading washers can either jam the motion of the agitator, overloading or damaging the motor or gearbox, burning drive belts, or tearing fabrics - many Whirlpool/Kenmore machines even have a mechanical "fuse" designed to break before the expensive motor is damaged. Extreme overloading can also push fabrics into the small gap between the underside of the agitator and the bottom of the wash basket, resulting in fabrics wrapped around the agitator shaft, possibly requiring agitator removal to unjam. Some top-loading machines use mechanisms very similar to front-loading drum machines, and are described below.

Many of these devices use brushless DC electric motors with permanent magnets attached to the moving hub which turns around a fixed armature which offer high efficiency, good speed-torque characteristics and low weight. This motor is often built into the wheel itself, eliminating gears and drive belts. Many devices have a motor in the 250-500 watts range which provides good performance for an adult rider on the flat and on an incline, with sportier models using motors in excess of 1500 Watts. Brushless DC motors, which often have regenerative braking, also need complex motor controllers.

The helical offset tooth design forms a chevron pattern and causes the teeth to engage progressively. The chevron pattern design is self-aligning and does not make the noise that some timing belts make at certain speeds, and is more efficient at transferring power (up to 98%). Disadvantages include a relatively high purchase cost, the need for specially fabricated toothed pulleys, less protection from overloading, jamming, and vibration due to their continuous tension cords, the lack of clutch action (only possible with friction-drive belts), and the fixed lengths, which do not allow length adjustment (unlike link V-belts or chains).

Harmonics and torsional vibrations can greatly reduce crankshaft life, or cause instantaneous failure if the crankshaft runs at or through an amplified resonance. Dampers are designed with a specific weight (mass) and diameter, which are dependent on the damping material/method used, to reduce mechanical Q factor, or damp, crankshaft resonances. A harmonic balancer (sometimes crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and other crankshaft driven devices.

James Dean (top) in Rebel Without a Cause wearing engineer boots Both Chippewa and Wesco heavily increased sales of engineer boots in the late 1940s. There was a post-war production boom for the boots, with high demand coming from returning veterans and bikers. The latter adopted engineer boots because the laceless design would not interfere with motorcycle drive belts, the shafts were well insulated from heat, and they provided full lower leg protection in case of an accident. The footwear's popularity was furthered by its use by celebrities such as Marlon Brando and James Dean in their respective films The Wild One (1953) and Rebel Without a Cause (1955).

As a temporary measure, in 1982, R22 operators received a kit from Robinson that was installed in the cockpit and on the belt tension actuator, isolating the tensioning circuits and locking the clutch/drive system at take-off tension. The problem was ultimately solved by replacing the four individual v-belts with two dual v-belts. The upper, driven sheave is mounted on the main/tail rotor drive shaft incorporating flexible couplings, and is raised and lowered relative to the engine-mounted, driving sheave by means of a belt tension actuator. During shutdown, the actuator is used to lower the upper sheave to loosen the drive belts.

K16 models used MEMS, with a 1.6 ECU from 1990 until 1994 and a 1.9 ECU from 1995 onwards, in either Single Point or Multi Point forms, with a single coil on the back of the engine block and a distributor cap and rotor arm on the end of the inlet camshaft. MEMS 2J was used on the VVC engine, to control the Variable Valve Control and the Distributorless Ignition System, which was used because there were camshaft drive belts at both ends of the engine. With the launch of the Rover 25 and Rover 45 in 1999, MEMS 3 was introduced, with twin coils and sequential injection.

"Moped" means a device upon which a person may ride which is DOT Approved. Under the statute, mopeds must be registered. To be registered under Hawaii law a moped must bear a certification label from the manufacturer stating that it complies with federal motor vehicle safety standards (FMVSS). A moped must also possess the following equipment approved by the D.O.T. under Chapter 91: approved braking, fuel, and exhaust system components; approved steering system and handlebars; wheel rims; fenders; a guard or protective covering for drive belts, chains and rotating components; seat or saddle; lamps and reflectors; equipment controls; speedometer; retracting support stand; horn; and identification markings.

The United States Rubber Company gradually took control of the company. The United States Rubber Company was renamed Uniroyal in 1961 and North British took on this name when eventually taken-over in 1966. In that year, Uniroyal relocated the tyre manufacture to Newbridge, then outside Edinburgh.D Easton (ed.), By The Three Great Roads, Aberdeen University Press, 1988, In 1957 Castle Mills began the production of Royalite thermoplastic sheeting. In 1967 Royalite production was moved to a new factory adjacent to the tyre plant at Newbridge. The manufacture of PowerGrip drive belts was relocated to the former Arrol- Johnston factory at Heathhall, Dumfries around 1970.

The majority of Gravely riding tractors are, like the walk-behinds, characterized as "all-gear", that is, with a rear-mounted engine mated to a transaxle powering the tractor's rear wheels. This design thus eliminates the need for drive belts to power the tractor forward or backwards. The only belts required on Gravely equipment (with the exception of the 408) is the blade drive belt for its mower decks, which is powered by a gear box on the deck, which receives power from a PTO driveshaft connected to the tractor's drivetrain. The tractor's direction is controlled by a lever to the right of the operator for forward, neutral, or reverse operation.

The advertised power drop from 1971 to 1972 ('71 304/210 hp and '72 304/150 hp, for example) is not due to any engine change, but to in the way the automobile industry adopted SAE power rating method. The 1971 and 1972 engines produce the same power. The 1971 and earlier versions were rated using "gross" horsepower, which is with the engines operating with no accessories or drive belts, air filters, nor any exhaust system restrictions. The change to the more realistic "net" horsepower ratings for 1972 and later required the engine to be driving all stock factory accessories and to use the factory air filter system and a simulated factory exhaust.

He was an advocate of the "free flow of ideas" He is credited with strengthening the dealer network and for Harley-Davidson's expansion to China, including opening dealerships in Beijing and Shanghai. After accepting his first job at Harley- Davidson, Bleustein soon became an "avid biker" Early in his time with the company, he was embarrassed to discover that his new Harley-Davidson Sportster was leaking oil, and this motivated him to redesign the engine to eliminate the oil leak problem. He was responsible for other engineering innovations, including rubber engine mounts to reduce vibration, redesign of the iconic Harley-Davidson V-twin engine, and introduction of Kevlar drive belts. He was an active participant in the Harley Owners Group, attending six or more events each year.

Rather than the pulled rubber drive belts as used in the past by DAF, the modern transmission is made much more durable by the use of electronic control and steel link belts pushed by their pulleys. A difference between the North American car market and the markets of Europe and Japan is the price of fuel. Fuel is heavily taxed and therefore relatively costly in most first-world markets outside North America; fuel is about two and a half times the price in the UK than the U.S. Fuel costs are also a much higher proportion of income, due to generally higher wages and lower living costs in the U.S. Only during occasional fuel price spikes such as those of 1973, 1979–81, and 2008-9 have North American drivers been motivated to seek levels of fuel economy considered ordinary outside North America.

The station is an example of late-Victorian Romanesque Revival architecture and has high towers and turrets that are reminiscent of a castle. The tower originally contained an early mechanical digital clock, but it was replaced by a traditional analog clock when replacement French silk drive belts became unavailable during World War I. The original bronze statue of the Roman god Mercury that sat on top of the tower was toppled in a storm in 1951 but was later replaced in the mid-1990s with a two-dimensional form painted in trompe l'oeil style to replicate the original. This second Mercury was destroyed in the 1998 downtown Nashville tornado but was also replaced. The décor in the hotel includes features like three crystal chandeliers, Italian marble floors, wrought iron accents, oak-accented doors, and three limestone fireplaces, along with a 65-foot, barrel-vaulted, stained glass lobby ceiling.

As the next bale is formed the tied one is driven out of the rear of the baling chamber, where it can either drop to the ground, or sent to a wagon towed behind the baler. When a wagon is used, the bale may be lifted by hand from the chamber by a worker on the wagon who stacks the bales on the wagon, or the bale may be propelled into the wagon by a mechanism on the baler, commonly either a "thrower" (parallel high-speed drive belts which throw the bale into the wagon) or a "kicker" (mechanical arm which throws the bale into the wagon). In the case of a thrower or kicker, the wagon has high walls on the left, right, and back sides, and a short wall on the front side, to contain the randomly piled bales. This process continues as long as there is material to be baled, and twine to tie it with.
