A calculation method of tooth profile modification for tooth contact analysis technology

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018
Tooth contact analysis (TCA) technology is an approach for computerized simulation of meshing of aligned and misaligned gear, which has been widely used in the design of gears. In TCA technology, the gear modification is completed by first modifying the cutter and then using the cutter to cut the gear blank.

The Tooth Profile Modification in Gear Manufacture

Applied Mechanics and Materials, 2007
The gear design always be focus on analyzing the static performance (strength, stress, friction) and dynamic performance (inertia, noise, vibration), and especially for dynamic, the noise and vibration of gear are big problems. Actually, the main reason of noise and vibration is transmission error between master and slave gears, but the error must ...
