What are the conditions to ensure the normal operation of the polyurethane timing belt meshing transmission?

We need to understand the characteristics of the meshing form of polyurethane timing belts. First, let’s understand what meshing transmission is. Synchronous belt drive, gear drive, and chain drive all belong to meshing drive. The drive of the synchronous belt is similar to the chain drive, but the number of meshing teeth is more than that of the chain drive.

The meshing transmission of the polyurethane timing belt must meet the following three conditions in order to prevent interference:

1. The pitch line of the synchronous belt and the pitch line (pitch circle) of the pulley must be completely coincident.

2. The pitch of the synchronous belt and the pulley must be equal.

3. The tooth slots of the synchronous belt and the teeth of the synchronous belt must be able to transmit power well during transmission without interference.

In the above three conditions, the first and second points can be guaranteed by ensuring the processing accuracy of the polyurethane timing belt and pulley and the use of a non-elongation strength layer.

Condition 3 can be guaranteed by analyzing the meshing motion.
