SUMMARY

The discussion centers on a project involving a shaft that must limit its rotational motion within a fixed cylinder until a specified torque is reached. The user seeks solutions that do not rely on electric power or magnetorheological (MR) fluids. Suggestions include utilizing surface-to-surface friction with known coefficients of friction (COFs) and contact area, or implementing a torque limiter clutch mechanism. A reference to a torque limiter clutch from Mayr is provided as a potential solution.

PREREQUISITES
  • Understanding of torque and rotational motion mechanics
  • Knowledge of surface friction and coefficients of friction (COFs)
  • Familiarity with hydraulic systems and their applications
  • Basic principles of clutch mechanisms and torque limiters
NEXT STEPS
  • Research surface-to-surface friction calculations and their applications in mechanical systems
  • Explore hydraulic torque limiter designs and their operational principles
  • Investigate mechanical clutch systems and their configurations for torque limiting
  • Examine the specifications and applications of the Mayr torque limiter clutch
USEFUL FOR

Mechanical engineers, product designers, and anyone involved in the design of rotational motion control systems will benefit from this discussion.

First time poster here, thanks in advance!

I have a project I'm working on, and I'm looking for a way to limit the rotational motion of a shaft inside a cylinder. The cylinder is fixed, and the shaft is spinning inside the cylinder coaxially. Basically, torque will be applied to the shaft, and I need the shaft to not spin relative to the cylinder until a specified torque, then it can "break free" and start to spin.

Anyone have a good idea on how to limit this motion? Surface to surface friction with known COFs and contact area? Hydraulically somehow?

I'd like to do it without the use of anything like MR fluid or needing electric power. Don't know if that's possible, but figured I'd throw it out here for some thought.

Thanks!

Like a torque limiter clutch with the output shaft fixed?: https://www.mayr.com/synchronisation/documentations/img_402_v09_en_22_05_2018.pdf

Ah, yup. Something just like that is what (I think) I'm after. Thanks!
