SUMMARY

The calculation of resistance force in a gearbox involves understanding the frictional forces at play, particularly from bearings and gear teeth. SKF provides reliable formulas and data for determining bearing friction, which is essential for accurate calculations. Additionally, the lubrication type affects gear teeth friction, which increases with load and potentially with speed. This information is crucial for determining the force required to turn a shaft at the input side of the gearbox.

PREREQUISITES
  • Understanding of gearbox mechanics
  • Knowledge of bearing friction principles
  • Familiarity with lubrication types and their effects
  • Basic principles of force and torque calculations
NEXT STEPS
  • Research SKF bearing friction formulas
  • Explore the impact of lubrication on gear teeth friction
  • Learn about torque calculations in mechanical systems
  • Investigate the relationship between load, speed, and resistance force
USEFUL FOR

Mechanical engineers, gearbox designers, and anyone involved in the analysis and optimization of gearbox performance.

Resistance force??

How is resistance force from the input thru to the output of a gearbox calculated? I want to know how to figure out how much force is required to turn a shaft at the input side of my gearbox. Any help would be greatly appreciated.

The bearing makers should be able to tell you the friction of the bearings. SKF is pretty good with formulas and data for this sort of thing.

The gear teeth friction will depend on what kind of lubrication you have and will increase with load, and possibly with speed also.
 


Thanks Unrest. I will use the info today!
