- How to calculate torque on a rotating gear driven by a hydraulic ram.
Please disregard this post if this forum is only academia related. This is a real word physics question.
I work in a hydraulic cylinder repair shop. I have a hydraulic machine that can tighten and loosen bolts and nuts with a lot of torque. When tightening, it is important to know how many foot/pounds of torque was used.
Here is how the machine works. A hydraulic ram pushes on the circumference of a cog that has a socket in the center. The hydraulic ram has a 4” diameter piston. So the surface area of the piston is about 13 square inches.
Assuming the ram is pushed with 100 PSI of force, what is the torque delivered to the socket? Does the cog provide additional torque, similar to a lever? Does the angle of the ram engaging with the cog affect the torque? What additional information do you need to provide an accurate answer?
Here is a crude diagram pieced together from clip art. Hopefully it helps to illustrate the problem.
