Spline and sliding
Spline and sliding
(OP)
Short question:
- which is the best spline for axial translation when the spline is exposed to moment?
- which is the best spline for axial translation when the spline is exposed to moment?

RE: Spline and sliding
For low speed; 'major and minor diamter fit' parallel spline.
For high speed; 'major and minor diamter fit' involute spline with a low pressure angle.

RE: Spline and sliding
There have been (nylon?) plastic coatings used with some success on automotive and industrial splined joints. Reduced noise (reduced stick/slip) and wear are among the claims. Specifics about axial force vs torque being transmitted are harder to come by.

Some of the Kluber pastes earned my respect virtually eliminating fretting in splined joints in some machine tool spindles.
When it really matters (front wheel drive, full wheel torque, inner joint) they go right to what is essentially a roller spline as part of the CV joint.
