In the production and processing of gear, the processing of key groove is a crucial link, it not only influences the connecting strength of gear and shaft, also is directly related to the stability and precision of gear transmission;

[0003] Particularly the angle uniformity of key groove, if there is uneven condition, will lead to vibration, noise in the transmission process of gear, even cause the early damage of gear, seriously affect the performance and service life of mechanical equipment.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a gear keyway angle detection device for gear manufacturing and processing, which can automatically detect the uniformity of gear keyway angles. A loading groove on the detection platform, along with a limiting groove inside the loading groove, is used to load a rotating detection shaft. The rotating detection shaft, inserted into the inner side of the loading groove, drives a first loading seat to rotate, which in turn drives the gear to rotate, thus detecting the keyway angle of the gear and identifying gears with uniform keyway angles. A limiting block fixedly installed on the rotating detection shaft extends to the inner side of the limiting groove, thereby limiting the rotation of the rotating detection shaft and making its rotation more stable, thus ensuring the accuracy of gear detection. An arc groove on the limiting block is used to load ball bearings. The ball bearings, with clearance fitting inside the arc groove, rotate during the rotation of the rotating detection shaft, causing the limiting block to rotate, which in turn drives the ball bearings to rotate. Simultaneously, the ball bearings also rotate within the limiting groove, further contributing to the smoother rotation of the rotating detection shaft and improving the accuracy of keyway angle detection.

[0014] The detection block is loaded using a detection slot on the detection platform and a sliding groove on the inner side of the detection slot. During gear detection, the detection block meshes with the detection gear, causing the detection gear to rotate. When the keyway on the gear rotates and an uneven angle appears, the detection block will be displaced. At this time, the displacement sensor detects the pressure transmitted from the support seat, thereby realizing the detection of the uniformity of the keyway angle. Attached Figure Description
