Shrink fits
Shrink fits
(OP)
We are currently reburbishing a customers gearbox not manufactured by ourselves.
The situation is we have a shaft onto which a gearwheel is shrunk on.
The trouble is that the shaft has a 1:32 taper. What I need to know is info about the torque it will be able to transmit and also, how to install the gear. I have a feeling it is oil injection but could it be forced on with hydraulic rams.
Thanks
Mike

RE: Shrink fits
I remember doing those calcs once while not long out of school, I'd have to dig deep to find 'em. (but since I never throw anything away, so I'm pretty sure I'd find 'em - eventually). If no-one replies I'll search for those notes. However, as I remember they were rather straight-forward, nothing out of the ordinary, I did them without consulting anyone else, so they couldn't have been too hard....

Ok here are some more details. The start of taper is 150mm dia end of taper is 146.25 dia over a distance of 123mm. There is no keyway.
