We have three ways:

1) double-D with a set screw to keep it from coming off (the set screw doesn't carry any torque load, it just keeps the gear from sliding off of the shaft.

2) Welding (we rarely use this).

3) Key-way with key stock. This has become our preferred method over the past two years. We've never had a failure, it's easy to implement, and easy to fix and replace. (as a note, just like the double-D, we use a set-screw to keep the gear from sliding off the shaft)
