A heavy-duty hollow rotary table must both rotate the fixture and support its working loads. These are separate design checks: enough driving torque does not automatically mean that the output bearing, mounting flange or machine base can support the application. What the hollow spindle does The central opening provides a route for cables, pneumatic lines,…

A planetary gearbox reduction ratio compares input speed with output speed. A 10:1 reducer turns its output once for every ten input revolutions. The right ratio must satisfy output speed, torque and the complete motion cycle. How to calculate reduction ratio Ratio i = input speed / output speed. Therefore, output speed = input speed…
