Abstract

The invention provides a shaping method and a manufacturing method for an involute straight tooth planetary transmission gear. The shaping method comprises the following steps of: acquiring a scheduled load value; obtaining torsion deformation quantity of the tooth width segment of a sun wheel shaft, bending deformation quantity of the tooth width segment of a planetary wheel shaft and elastic deformation of gear teeth of a planetary wheel according to the scheduled load value; determining an initial value of shaping quantity according to the torsion deformation quantity of the tooth width segment of the sun wheel shaft, the bending deformation quantity of the tooth width segment of the planetary wheel shaft and the elastic deformation quantity of gear teeth of the planetary wheel; shaping the involute straight tooth planetary transmission gear in a virtual environment according to the initial value of the shaping quantity; estimating and verifying the shaped involute straight tooth planetary transmission gear; and determining the final shaping quantity according to estimation and verification results. According to the shaping method, the shaping difficulty is low, the shaping quantity is small, unbalanced loading of the engagement of the planetary gear is eliminated, the transmission stability of the gear is further improved, the bearing capability of the gear is enhanced, and the service life of the gear is prolonged.

Description

technical field [0001] The invention relates to the field of gears, in particular to a modification method and a manufacturing method of an involute spur planetary transmission gear. Background technique [0002] Due to the needs of modern industrial applications, gear transmission systems are developing towards low speed heavy loads and high speed heavy loads. Due to its unique advantages, planetary gear transmission is widely used in aviation, engineering machinery, ships, wind power generation and other fields. High reliability, long life, low noise and vibration levels of gear transmission have always been the goals pursued by gear transmission designers. However, due to factors such as manufacturing and installation errors, elastic deformation of the support system and elastic deformation of the gear teeth Impact, the gear pair will inevitably produce shock, vibration, unbalanced load and other phenomena during the meshing process, which will lead to early failure of t...
