toothed pulleys or sprockets. Toothed belts are used in a wide array of mechanical devices where high power transmission is desired. Timing belts, toothed...

movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can...

In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the...

A pulley is a wheel on an axle or shaft enabling a taut cable or belt passing over the wheel to move and change direction, or transfer power between itself...

etc. The belt may also be guided by an idler pulley and/or a belt tensioner (which may be spring-loaded, hydraulic, or manual). To allow the belt to pass...

electrically-controlled hydraulic units, mounted in the camshaft's timing belt pulley. These systems are fitted to the Volkswagen VR5 and VR6 engines, and...

A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured)...

frame. Belt-driven bicycles and their repair or replacement parts are scarcer at shops than bicycles with conventional chain. Front and rear pulleys or sprockets...

and differs from a pulley in that sprockets have teeth and pulleys are smooth except for timing pulleys used with toothed belts. Sprockets are used in...

rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and other crankshaft driven...

thickness tolerance of the belts, the accuracy of the cam timing is also affected by the positional and diameter tolerance of each pulley and the thickness of...

tension. The serpentine belt and the timing belt or chain on an automobile engine may be guided by an idler pulley and/or a belt tensioner, which may be...

keep the belt taut, the Beltrex uses a floating pulley that's cogged to the drive gear. Tension on the pedal cranks drives the floating pulley forward...

was to go from a square toothed timing belt set up to a round toothed timing belt setup which made for quieter belt running. Although availability of...

features a cast iron block, an aluminium head, and a timing belt driven valvetrain. The timing belt also drives the water pump. It was first used in the...

B-series is a "non-interference" design, meaning that breakage of its timing belt does not result in damage to valves or pistons, because the opening of...

or main (drive) pulley smaller or making the accessory (driven) pulley larger than the original diameter pulleys. Underdrive pulleys increase engine output...

tire) so that the middle of the pulley was a slightly larger diameter. This kept the flat belt in the center of the pulley. By the 1930s, more-advanced engines...

Speed reduction is via a standard twin cog-belt system, with harmonic dampening on the crankshaft pulley. The initial TBO was estimated by the manufacturer...
