I have an aluminium bearing holder attached to one end of an aluminium plate as follows:
The bearing holder is attached to the plate by two bolts on the bottom. The intended setup is to attach a relatively heavy load to the right hand side of the shaft. To reduce stress on the two bolt holes in the plate, is it a good idea to have a lip on the plate as shown? Will it actually have any effect? Ideally I'd like to fasten the bearing holder through the lip, but I'm trying to avoid machining from the side and stay away from 4-axis machining.
Are there better ways to reduce the stress on the holes?
Any advice appreciated.
