The pin hub has a set screw which is used to temporarily secure the gear to the shaft.  Approximately 90° from the set screw there is a sub drill or spot drill that is used as a guide to drill the hub and the shaft for pinning or assembly.  This method has a disadvantage in that it weakens the shaft.  The designer should also remember that it is difficult to remove the pin hub gear from the shaft without damaging both components.  After pinning, the set screw is removed so it cannot work its way loose and fall into the mechanism.



Pin hub gears can be assembled to the shaft using dowel pins, spring pins, roll pins, or taper pins.  The hole should be drilled to the correct size for the specific pin that has been chosen.  When drilling, staking, etc. it is important to be careful and not damage the gear teeth in any way.  All loose material from drilling should be removed prior to assembly.
