PU timing belt working principle and installation

by:Uliflex     2020-05-20
The PU timing belt drive is composed of an endless belt with equal-spaced teeth on the inner peripheral surface and a belt pulley with corresponding teeth. During operation, the belt teeth mesh with the tooth groove of the pulley to transmit motion and power. New belt drive with belt drive and chain drive gear drive. Precautions for installation and use of PU timing belt and timing wheel: Reduce the center distance of the pulley. If there is a tensioner, loosen it first, and then adjust the center distance after installing the belt. For the transmission with fixed center distance, the pulley should be removed first, and then the belt is installed on the pulley, and then the pulley is installed on the shaft to fix it. The following points should also be noted during installation: ①When installing the synchronous belt, if the center distance between the two pulleys can be moved, the center distance of the pulley must be shortened first, and then the center distance should be reset after installing the synchronous belt. If there is a tensioner, first relax the tensioner, then install the timing belt, and then install the tensioner. ② When installing the synchronous belt on the pulley, remember not to use excessive force or pry the synchronous belt with a screwdriver to prevent the tensile layer in the synchronous belt from causing unsightly breakage. When designing the pulley, it is better to choose the structure where the two shafts can move closer to each other. If the structure does not allow it, it is best to install the timing belt and the pulley together on the corresponding shaft. ③ Control proper initial tension. ④In the PU timing belt drive, the parallelism of the axis of the two pulleys is relatively high, otherwise the timing belt will run out of position during work, or even jump out of the pulley. Non-parallel axes will also cause uneven pressure, causing early wear of the teeth. ⑤The rack supporting the pulley must have sufficient rigidity, otherwise the two axes will not be parallel when the combination lock is running.
