Shearing when bolts are arranged radially

  • #1
Hi folks,

I'm currently working on a final year project on the design of a plunger pump. The most recent area I have been studying is the loading on different joints in the pump. For a simplified example I have determined the maximum torque load on the crankshaft from the plungers for the desired operating pressure. Since the project is a design project I thought it would be interesting to also include some bolt shearing calculations to justify the design of the input flange on the pump.

I recall learning bolt shearing in 1st year however, that's only because the lecturer pronounced the word "bolts" as "balls", with hindsight I wish I had taken notes instead of laughed. I recall the formula T=τAnr where T=torque τ=shear stress A=cross sectional area of bolts n=number of bolts and r= radius of bolt placement.

Could someone please suggest a good reference where I can read about this? We have been told by the head of final year projects that projects submitted without a sufficient number of textbook references will lose marks.

Shigley' Mechanical Engineering Design comes to mind. If you don't already have it, you should invest in it
