Synchronous Belt Working Principle

- Aug 14, 2018 -

The timing belt transmission is composed of an endless belt with equal-spaced teeth on the inner peripheral surface and a pulley with corresponding teeth. During operation, the teeth are meshed with the tooth grooves of the pulley to transmit motion and power. A new belt drive with the advantages of transmission and chain drive gear transmission.


Timing belt and synchronous wheel installation and use precautions:


Reduce the center distance of the pulley. If there is a tensioning pulley, loosen it first, then adjust the center distance after attaching the strap. For fixed center distance transmission, the pulley should be removed first, and the belt should be attached to the pulley before the pulley is fixed to the shaft.


The following points should also be noted during installation:


1 When installing the timing belt, if the center distance of the two pulleys can be moved, the center distance of the pulley must be shortened first, and then the timing belt is installed, and then the center distance is reset. If there is a tensioning wheel, first relax the tensioning wheel, then install the timing belt, and then install the tensioning wheel.


2 When attaching the timing belt to the pulley, remember not to use too much force, or use a screwdriver to harden the timing belt to prevent the tensile layer in the timing belt from being broken by the appearance. When designing the pulley, it is better to use a structure in which the two shafts can move closer to each other. If the structure is not allowed, it is better to attach the timing belt to the corresponding shaft together with the pulley.


3 Control the appropriate initial tension.


4 In the synchronous belt drive, the parallelism of the two pulley axes is relatively high, otherwise the timing belt will run off when working, and even jump out of the pulley. Non-parallel axes will also cause uneven pressure, which will cause early tooth wear.


5 The frame supporting the pulley must have sufficient rigidity, otherwise the pulley will cause the two axes to be non-parallel when the combination lock is operated.
