1. Transition curve interference
Transition curve interference refers to the interference at the transition curve between the tooth tip of a gear and the tooth root of the matched gear during the meshing process.

 

2. In order to prevent interference in the transition curve during the meshing process, the selected meshing parameters must ensure that the tooth tips of the flexible and rigid wheels at the position of the maximum meshing depth of the gear teeth do not enter the transition curve part of the paired gear.

 

3. The maximum meshing depth of the gear is less than a specified value. In order to improve the load-bearing capacity of the transmission and appropriately expand the meshing range, it is necessary to limit it to no less than a certain specified value. In general, this value can be taken as equal to the modulus m.

 

The measures to improve the efficiency of gear meshing transmission include: replacing the driving gear with one with more teeth; Replace the driven gear with a transmission gear with fewer teeth; Gear transmission with appropriate thin oil lubrication.

      The factors related to the efficiency of gear transmission devices include:
1. The material and heat treatment state of gears are related
2. The manufacturing and processing accuracy of gear pairs is related to
3. The movement progress of gears and gear pair positioning devices is related to
4. Transmission form (open or closed)
5. Lubrication form
6. Cooling form
7. Environmental status
