Pitch calculation method for synchronous pulley

The pitch calculation of synchronous pulleys is a key step in mechanical transmission design, which directly affects the accuracy and matching of the transmission.

The following are systematic calculation methods and precautions: 1. Core concepts: Pitch definition

Refers to the axial distance between the center lines of two adjacent teeth, in mm (mm). Common standard pitches are: • MXL type: 2.032mm • XL type: 5.08mm • L type: 9.525mm • H type: 12.7mm • T5/T10: 5mm/10mm (arc tooth type) Key parameters of synchronous pulleys • Number of teeth (Z): Total number of teeth on the pulleys. • Diameter of the joint (D): The theoretical meshing diameter, calculation formula:
