Calculation formula for synchronous pulley

The calculation formula for synchronous pulley mainly includes the following aspects:

1. Calculation of the diameter of the segment circle: Dp = Pb × Z / π, where Dp represents the pitch, Pb represents the pitch, Z represents the number of teeth, and π represents the pi.

2. Calculation of actual outer circle diameter: De = Dp - 2a, where De represents the actual outer circle diameter, Dp represents the pitch diameter, and a represents the pitch distance.

3. Calculation of center distance: The calculation formula of the center distance is B = (L - 1.57(Dp + dp)) / 2, where B represents the center distance, L represents the length of the belt segment line, Dp represents the pitch diameter of the large pulley, and dp represents the pitch diameter of the small pulley. The above formula can help you perform basic calculations for synchronous pulleys. It should be noted that in actual applications, there may be certain errors due to factors such as manufacturing and installation. Therefore, these factors should be fully considered when designing and selecting, and sufficient safety margin should be left.
