Shear on bolts for a Decelarating rotating mass 4

[NewAtThis]

Hello all,

I have been asked to check some details for our customer.

We have an adapter on the spindle nose of a lathe, at a mass of around 335kg being held in place with 4 X M24 bolts and a drive dog.

The mass is rotating at 3300rpm. I want to check the force acting upon the bolts if the emergency stop is activated, which I assume is an immediate stop. To check the shear on the bolts and drive dog.

I have not seen this yet in the post, but once you find sheer load, you have to compare that to 1/2 of the yield strength of the material to see if you get satisfactory factor of safety.
