Abstract

The invention provides a face gear error detection and machining control method, device and system. The face gear error detection and machining control method comprises the following steps: obtaining tooth surface grid node coordinates of a standard face gear; determining a tooth surface grid node theoretical coordinate C and a tooth surface normal vector nc in the tooth center theoretical coordinate system according to the tooth surface grid node coordinate of the standard surface gear; acquiring the actual coordinate Tf of a tooth surface grid node in the actual coordinate system of the tooth center of the to-be-corrected face gear; determining a correction value H of the to-be-corrected face gear according to the theoretical coordinate C and the tooth surface normal vector nc of the tooth surface grid node in the tooth center theoretical coordinate system and the actual coordinate Tf of the tooth surface grid node in the tooth center actual coordinate system; and controlling the face gear correction equipment to correct the to-be-corrected face gear according to the correction value H. According to the scheme, operation is easy, face gear detection and machining precision is improved, errors are reduced, and meanwhile the method is suitable for error detection and control of tooth surfaces of different face gears.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a face gear error detection and processing control method, device and system. Background technique [0002] Face gears are the key components to realize intersecting or staggered transmission in space. They have many advantages such as large coincidence, strong bearing capacity, and stable high-speed transmission. They have broad application prospects in the fields of transportation, large equipment, aerospace, and construction machinery. Therefore, the precision manufacturing of face gears is one of the technological highlands and cutting-edge research fields that the world's manufacturing powers compete for a long time in the field of transmission. In the traditional machining of face gears, the semi-finishing and finishing methods generally use gear shaping or hobbing or milling + grinding. Grinding is one of the precision machining methods for curved gears. Since the...
