What are the correct meshing conditions for involute spur gears?
1 Answers
The correct meshing conditions for involute spur gears are that the module and pressure angle must be equal respectively; the gear contact ratio must be greater than or equal to 1. Advantages of involute gears: Installation errors in center distance do not affect the instantaneous transmission ratio of the gears. Meshing introduction: Refers to a transmission relationship between two mechanical parts, known as meshing transmission. Gear transmission is the most typical meshing transmission and also the most widely used form of transmission. According to different transmission principles, there are spur gear meshing transmission and helical gear meshing transmission. It can adapt to a very wide range of speed and power transmission. The circumferential speed can range from very low to as high as 300m/s; the transmission efficiency is relatively high, with a long working life, smooth transmission, and high reliability; it can ensure a constant instantaneous transmission ratio; it can achieve transmission between two shafts in various positional requirements.
