Operating Torque of Tapered Roller Bearings

Abstract

A theoretical derivation has yielded a general expression for the operating torque of a tapered roller bearing under pure thrust load. Experimental data have been obtained to enable determination of the constant and exponents to make this expression usable. Further theoretical analysis has extended the use of the thrust load equation to pure radial and combined radial and thrust loads. Comparison of calculated and measured operating torques under radial load has verified the theoretical derivation.

The bearing geometry variables from the basic torque equation have been combined into a G factor which represents the heat generation potential of a bearing.

A typical bearing application illustrates use of the equations.
