Research on the Influence of Temperature on the Cushioning Performance of Oil-air Landing Gear
The oil characteristics and inflation pressure inside the oil-air shock absorber will change with the ambient temperature,which will affect the cushioning performance of landing gear.In order to explore the effect of temperature on the cushioning ...

Abstract This paper investigates the resistance of micropitting on two materials, using an FZG back-to-back test rig with C-PT gears. The materials are wrought steel (16MnCr5) and a commercial powder metallurgical material (Astaloy™ Mo). Two finishing methods were studied: grinding and superfinishing. Experimental results show that the superfinishing

Study on Planetary Gear Drive Using Internal Gear Easily Ground
A planetary gear drive having the internal gear that can be easily ground is developed. This gear drive is composed of the three parts; the internal gear finished by the grinding wheel with a trapezoid profile, the planet gear conjugate to the internal gear, and the sun gear conjugate to the planet gear. In this paper, a method to design the gear tooth
