What Are the Correct Meshing Conditions for Gears?
1 Answers
Meshing transmission refers to a type of drive relationship between two mechanical components. Gear transmission is the most typical form of meshing transmission and also the most widely used drive mechanism. Depending on the transmission principle, there are spur gear meshing transmissions and helical gear meshing transmissions. The correct meshing conditions for gears are as follows: 1. Meshing conditions for spur cylindrical gears: The modules of the two gears must be equal, and the profile angles on the pitch circles of both gears must be identical. 2. Meshing conditions for helical cylindrical gears: The normal modules of the two gears must be equal, the profile angles must be the same, and the helix angles must be equal but in opposite directions. 3. Meshing conditions for straight bevel gears: The modules at the large ends and the profile angles of both gears must be equal, respectively.
