1. The problem statement, all variables and given/known data 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 2. Relevant equations n/a 3. 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.
