Gear-tooth profile modifications and gear-tooth crowning do not change the geometric dimensions of the gear smoothness and can distribute the contact stress throughout the tooth surface and improve the reliability and capacity of the gear transmission, the smoothness of transmission thus it can reduce the effect of heat deformation after machining, resulting in a longer life span and decrease the...
Gear mechanism is the most popular transmission mechanism, however, conventional design methods are complex and inaccurate. The optimum design solves the above mentioned problems effectively by means of applying to gear design. In numerous of optimization software, MATLAB holds obvious predominance on program and numerical calculation. Taking single gear transmission as an example, the math model...
The operational performance of gears regarding smoothness, quietness, wear and life span is largely affected by how gear and pinion teeth make contact. And the geometric characteristic of teeth profile plays a very important role in influencing contact condition during gear transmission. For a nominal involute gear pairs, load concentration on the conjugated teeth would be generated inevitably under...
