Spur gear selection for parallel shafts

  1. Feb 8, 2010 #1
    Hi,

    I have a DC motor with 4mm diameter shaft, flat tip.

    How can I attach a 12 teeth pinion to this drive shaft?. I have been loking for pinions and gears on the web but they don't specify how are they attached to a shaft, as there are round shafts and flat tip shafts. Do I have to ask for gears with hub and set screw?

    Any help would be very appreciated.

    There are many ways to do it, one of the simplest would be a set screw in the gear's hub, like on this W.M.Berg gear:

    The set screw is a good option but, is there any stainless steel gear that matches a flat tip shaft like this?

    Your question doesn't make a whole lot of sense. The flat is made for the set screw. Who/what are stanley steel gears?

    Thank you. I have seen some gears that have an opposite shape for flat tip shafts.
    PD: I'm sorry about the bad spelling.
