How to attach bearings on shaft

  1. Apr 4, 2012 #1
    I have a shaft, which I would like to rotate 90 degrees to one side and then 90 degrees back to the other side and so forth. How should I attach the bearings to this shaft? I was thinking to do it as shown in this image:

    Two slide bearings, one on the top and one on the bottom so the shaft can rotate. But how should I fix this movement vertically? I’m completely new to attaching bearings on shafts, so any help would be appreciated. It does not necessarily have to be done as shown in the image.

    The shaft at the middle portion can be thicker in diameter than the top and bottom portion.

    Yes, true. Didn't think about that. But how should I realize that?

    If there is no axial load, you can use external circlips

    if there is a load, perhaps you could look at the workings of a crank on a bicycle. Are you attaching anything to each end of the shaft? some shafts are frozen (reduced in size) then feed into the bearing and gradually heated to create a mate through expansion of metal, or you can have them press fitted.

    Hope this helps.

    if you need the shaft bears axial force, the shaft must have a shoulder, one bearing leans against the shoulder, it can support whole shaft.
    i suggest you refer to some books show a few structure inside gear box, it is useful for you.
