Here are the equations:
1/Rx = 1/rax + 1/rbx
1/Ry = 1/ray + 1/rby
1/R = 1/Rx + 1/Ry
I don't understand what the radius x and y values are how to tell whats what, the question I have been given is this:
The ball-outer race contact of a deep groove ball bearing has 10mm ball diameter, a 5.5 mm outer race concave groove radius and a 45 mm radius from the bearing axis to the bottom of the groove. The load on the ball is 500 N and the race and the ball are made of steel (E=206 GPa, v = 0.30). Apply Hertzian Contact Analysis to determine.
(a) - Curvature Sum (Include diagrams to define contact geometry).
From this I reckon it is talking about a rolling element bearing?
I know how to do the rest of the questions but I really don't understand how to find the curvature sum. I have searched on google and youtube but all I find is reports and simulations, none of which actually explain anything.
Thank you.
