Document Type and Number:
WIPO Patent Application WO/2022/135612
Kind Code:

Abstract:
Disclosed is a method for measuring a normal engagement tooth profile of an involute helical cylindrical gear. The method is used for measuring a normal engagement tooth profile on a tooth surface of a measured gear. A cross-axis involute helical cylindrical gear is driven to move by the normal engagement tooth profile. The normal engagement tooth profile is measured to reflect the actual movement working conditions such as the transmission quality and working stability of the gear. In gear hobbing, gear shaving and worm grinding-wheel grinding generating, movements of a tool and a gear are achieved based on the normal engagement tooth profile, and controlling the normal engagement tooth profile has a unique advantage in controlling the gear machining quality. Measurement is achieved by means of a gear measurement center, and use of four-axis linkage measurement effectively mitigates the problem that the measurement precision is prone to being affected by the size of a measured gear. Radial and axial movements are respectively restricted to achieve simplified measurement of the normal engagement tooth profile and engagement-based involute line measurement. The method is suitable for involute line measurement of straight-toothed cylindrical gears, and the normal engagement tooth profile on the tooth surface of the gear coincides with the involute line, thus the method is also suitable therefor.
