Finding the ideal materials for gears

When designing and manufacturing gears, the materials used will depend on what type of gear is being made and how and where it will be used.

When designing an individual gear or a gear train, the choice of material will either be the primary factor on which the gear geometry is based or the gear performance will dictate the proper material selection. There are various raw materials that are commonly used in gear construction, and each one has a sweet spot […]

Nonlinear dynamic characteristic analysis of a coated gear transmission system

The nonlinear dynamic characteristic of a DLC-coated gear transmission system is analyzed by using a numerical integration approach, and the effect of the coating elastic modulus on the dynamic response is investigated.

Coatings can significantly improve the load-carrying performance of a gear surface, but how they affect the vibration characteristic of the system is an urgent issue to be solved. Considering the nonlinear factors such as the variable mesh stiffness, friction, backlash, and transmission error, a six-degree-of-freedom spur gear transmission system with coatings is presented. Meanwhile, the […]
