Chat OnlineThey are open belt drive and crossed belt drive. The two types of belt drives are discussed below in brief. Open belt drives An open belt drive is used to rotate the driven pulley in the same direction of driving pulley. In the motion of belt drive power transmission results make one side of pulley more tightened compared to the other side.
Live ChatA belt drive is shown in the figure. consists of two pulleys over which an endless belt it passed over them. The mechanical power or rotary motion is transmitted from the driving pulley to the driven pulley because of the frictional grip that exists between the belt and the pulley surface.
Live Chat2019113The diameter of the driver and driven pulley is determined by the type and dimension of conveyor belting. The diameter of the pulley must be designed such that it does not place undue stress on the belt. The length of a belt conveyor in metres is the length from the centre of pulley parallel to belt

Live ChatTo determine the required motor drive torque for a belt and pulley system calculate the torque required acceleration constant velocity and deceleration. Belt driven linear systems are common in applications that require long travel and high speed such as
Live ChatWhen the center distance between the driver and driven shaft is very large and higher power is required to be transmitted rope drives are used. Here instead of belt wire rope is used. Appropriate sie and number of grooves are provided on the pulley rim. e.g elevatorlift overhead crane hoist rope way etc.

Live ChatSynchronous belts can wear rapidly if pulleys are not aligned properly especially in longcenterdistance drives where belts tend to rub against pulley flanges. To prevent the belt from riding off the pulleys one of them is usually flanged. A recent development has produced a belt and pulley that use a Vshaped instead of straight tooth shape.

Live Chat201066belt conveyor system. The conveyor carries material on the upper run of the belt and discharges the load over the head or drive pulley as the belt bends round the pulley. The empty belt returns below. The drive pulley or drum is powered by a motor through a suitable reduction unit. The driven pulley or drum acts as the takeup or tail pulley.
Live Chat2014124The tension in a conveyor belt decreases as the belt travels around the drive pulley causing the belt to contract. In order to prevent slip the lagging must deform circumferentially to match the belt contraction. The belt traction force causes this lagging deformation but if beyond the limit friction will allow slip. As the belt contracts it
