A method is described for calculating the efciency of planetary gear trains, and as an example the method is applied to the case of a fixed differential gear train.

ANSI/AGMA 2001 -B88, Appendix B presents the fundamental method for evaluating Miner's Rule. To analyze the load spectrum, stress values are calculated for a given load and then modifiled using“K or“C”factors. When computing the stesses for other...

The paper represents the results of accomplished research projects directed atreduction of noise caused by misalignment of the following gear drives: double- circular arc helical gears, modifed involute helical gears, face- milled spiral bevel gears and face-...

Most of the models proposed to predict the dynamic behavior of gears do not take into account the blank flexibility andits natural modes of vibration. In those models, a gears pair is reduced essntally to two rigid...

Load endurance tests have been conducted to obtain allowable surface compressive stresses for materials required for strength and high reliability of power gears. The following JIS materials were used in conducting the tests: spheric graphite cast iron,...

A method to accurately predict gear root stress for parallel axis gears is explored using a combination of three analysis techniques: boundary elements, elastic body contact analysis, and the moment-image method. The method is computationally faster than...

The Autark Hybrid is the power train for a universal vehicle that is able to drive in innercity areas with zero emission and is also suited to long distance driving. The combination of two power sources -...

Ausforming is a thermomechanical process which integrates surface induction heating with precision hot gear roll finishing, and is capable of finishing spur and helical gears, thereby eliminating tooth- grinding and some associated operations. Gears are in the...
