Under the actual working condition, the double-arc spiral bevel gear pair is in the state of multi-tooth meshing alternately. In

In the meshing process of double-arc spiral bevel gear pair, the process of single pair of teeth from entering meshing

Take the intermediate tooth (No. 4 tooth pair) of the double-arc spiral bevel gear in Figure 1 as the analysis

The tooth surface of the crown gear is composed of the tooth direction line and the double arc tooth profile

Nutation reducer is a new type of transmission based on the principle of gyroscopic motion. It is widely used in

By considering the influence of lubricating oil film on heat transfer, the traditional Blok flash temperature formula is improved, and

For two surfaces in sliding contact, heat is usually generated by friction between contact areas. The frictional heat generation per

When the spiral bevel gear is running, the working conditions of each tooth are completely consistent, so it can be

With the rapid development of automobile industry and aviation industry, spiral bevel gears have been widely used due to their

The free mode and contact mode of Gleason spiral bevel gear are analyzed. The mode of Gleason spiral bevel gear

The equivalent stress nephogram and equivalent displacement nephogram of spiral bevel gear under stable working condition are shown in Fig.

Modal analysis is mainly used to determine the internal characteristics of Gleason spiral bevel gear. On this basis, it can

1. Establishment of finite element model Several key problems in the establishment of finite element model include the selection of

The structure of Gleason spiral bevel gear is complex. In order to accurately simulate the stress condition of spiral bevel

The spiral bevel gear with installation error will affect the meshing quality, vibration noise, tooth surface contact mode, etc. of

Compared with the straight bevel gear, the spiral bevel gear will increase the overlap between the teeth when meshing. Therefore,

The roughness result determines the quality of spiral bevel gears. For the sawtooth cutting mode, the roughness value of Ra
