How to attach a gear to a static shaft?

[DavidGray32]

Homework Statement

A shaft is being used as a cantilever and is held in the housing by its fit. It is to remain static whilst a gear is attached to the free end, how to you retain the gear on the free end of the shaft? Sketch a suitable method

The Attempt at a Solution

I understand the shaft is being held by a clearance fit and the question is essentially asking how do you stop the gear from slipping off. I'm thinking you'd have to use a bearing to allow the gear to rotate freely around the shaft. I'm not sure if this is correct or if I'm looking at this the wrong way.

A shaft is being used as a cantilever and is held in the housing by its fit.

This statement seems to indicate that the shaft is supported in a press fit or shrink fit, not a clearance fit. Presumably this is an idler gear, turning freely on the end of a non-rotating shaft.

Sorry, it was interference fit!

Perhaps look at something similar such as the front wheel bearing of a ride on lawn mower?

 

[Dr.D]

Is the situation such that you want to put a bearing between the gear and the shaft, or do you want the gear to run directly on the shaft? Either way, you can use something like a large washer with a cotter key, a nut on the end of the shaft, or a ring with a set screw.
