The open belt drive has parallel shafts rotating in the same direction, whereas the cross-belt drive also bears parallel shafts but rotate in opposite direction. The former is far more common, and the latter not appropriate for timing and standard V-belts unless there is a twist between each pulley so that the pulleys only contact the same belt ...
Four wool spinning machines driven by belts from an overhead lineshaft (Leipzig, Germany, circa 1925) The belt drives of the Mueller Mill, model and reality, in motionA line shaft is a power-driven rotating shaft for power transmission that was used extensively from the Industrial Revolution until the early 20th century.
Rope drive in a hydroelectric plant Multiple rope drives driving lineshafts on each factory floor. The rope drives were placed in a large diagonal shaft at the side of the building, usually windowless and distinctively visible from outside the building. [ii] Rope drives required a larger such shaft than comparable belt or shaft drives.
A single shaft runs below the rollers running the length of the conveyor. On the shaft are a series of spools, one spool for each roller. An elastic polyurethane o-ring belt runs from a spool on the powered shaft to each roller. When the shaft is powered, the o-ring belt acts as a chain between the spool and the roller making the roller rotate.
Flat belt on a belt pulley Belt and pulley system Cone pulley driven from above by a line shaft. A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.
The shaft can be a single “through” shaft where the motor and gearbox are assembled on, and fixed to, the shaft with keys or pins. However, this type of drum motor design has a limited maximum radial load due to the bending stresses caused by the normal belt tension of a conveyor and is therefore used mainly for small light duty conveyors ...
A drive shaft system weighs more than a chain system, usually 0.5–1 kg (1–2 lb) heavier. Many of the advantages claimed by drive shaft's proponents can be achieved on a chain-driven bicycle, such as covering the chain and sprockets. Use of lightweight derailleur gears with a high number of ratios is impossible, although hub gears can be used.
Simple CVTs combining a centrifugal drive pulley with a spring-loaded driven pulley often use belt tension to effect the conforming adjustments in the driven pulley. [3] The V-belt needs to be very stiff in the pulley's axial direction to make only short radial movements while sliding in and out of the pulleys. The radial thickness of the belt ...
