Still determining what it takes to bear the forces on a steering wheel …
↓↓↓ Complete description, time index and links below ↓↓↓

Last time we covered the axial forces, that is what we need to keep that shaft being pushed/pulled out of the bearing, and the bending of the POM bearing under radial loads (link below). But there are more parts we need to make calculations for.

First, we have a look at the initial drawing. Then we calculate the required thread lengths for the steering wheel and bearing mounting bolts. Finally we talk about torque: What shaft keys are needed to transfer it and what bolts to stop it.

00:00 Intro – last video with calculations, I promise
01:07 Initial drawing – and how I came up with it
06:47 Wheel bolts – how long need the threads to be
14:22 Bearing bolts – how long need the threads to be
21:59 Shaft keys – how large do they need to be
26:41 Stop bolts – what diameter do they need to be
33:33 Wrap-up – next is the final drawing and machining, bye
