This information sheet provides a method for calculating thepitting resistance and bending strength of hypoid gears using theprocedures of ANSI/AGMA 2003-B97.
Rating formulas
The knowledge and judgment required to evaluate the variousrating factors come from years of accumulated experience indesigning, manufacturing and operating gear units. Empiricalfactors given in this document are general in nature. AGMAapplication standards may use other empirical factors that are moreclosely suited to the particular field of application. Thisdocument is intended for use by the experienced gear designer,capable of selecting reasonable values for the factors. It is notintended for use by the engineering public at large.
Exceptions
The exceptions in clause 1.2 of ANSI/AGMA 2003-B97 apply forhypoid gears. Lengthwise sliding in hypoids reduces theirefficiency. Torque losses between driving pinion and gear rangefrom 2 to 15 percent depending on the offset, spiral angles,velocity and lubrication. The equations neglect and lubrication.The equations neglect efficiency. The user can adjust input oroutput to account for losses.
