Abstract

The invention belongs to the technical field of mechanical processing, and relates to a method for assembling and adjusting spiral bevel gears. The adjustment quality of the spiral bevel gear assembly mainly takes the adjustment quality of the contact area as an important index. The position and shape of the contact area of ​​the tooth surface have an important impact on the working stability, life and noise of the spiral bevel gear. According to the structural characteristics and working principle of the spiral bevel gear itself, the present invention analyzes the trend of the gear backlash along the tooth length with the change of the installation distance, which leads to the trend of influence on the position of the gear contact area, and the change of the gear backlash. The position of the contact area of ​​the tooth surface of the gear changes accordingly, and with reference to the actual operation results, the assembly adjustment method is summarized.

Description

A method for assembly and adjustment of spiral bevel gears technical field The invention belongs to the technical field of mechanical processing, and relates to a method for assembling and adjusting spiral bevel gears. Background technique Spiral bevel gears are widely used in the transmission system of aero-engines due to their stable transmission, low noise, and strong load-carrying capacity. In the transmission process, the contact area of ​​the tooth surface of the spiral bevel gear is one of the important signs to measure the meshing quality of the gear. In the assembly process, the adjustment of the contact area is also a particularly important technology. Usually, the adjustment of the contact area is achieved by changing the gear installation distance. However, in the actual adjustment process, the influence of the unevenness of the backlash of the spiral bevel gear in the tooth length direction on the contact area is ignored, which leads to the blind adjustment ...
