Good day,

Can someone guide me on how to approach the design of a pulley end-disc. I've been reading up on some texts, but none of them seem to go into detail with regards to its design. Thus far I've been considering approaching the design using "rotating disc" theory. Am i on the right path?

Right now, i have two main concerns:

1. What is the assumed working stress on the end-disc? Do I take it as the max stress that can be handled by the weld at the end-disc to shell connection?

2. Designing the profile of the end-disc (may it be a Turbine, L or T-bottom).

Any insight with regards to the this topic will be highly appreciated. Please not that I'm asking for answers, but rather guidance/"coaching" in approaching the design. Furthermore I would greatly appreciate it if I could get guidance on continuous basis, when I come up to some stumbling blocks.

Thank you.

Regards,
