[0058] The specific implementation of the special detection device and detection method for the pitch circle diameter of the inner star wheel raceway of the VL type universal joint of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0059] See attached Figures 2 to 8 , because the six raceways of the inner star wheel are uniformly distributed only on the system plane BB, the diameter error value of the circle (that is, the pitch circle) formed by the centers of the six raceways on the system plane BB is ±0.05mm, Figure 8 Among them, points O1 and E1 represent the center of the raceway and the most concave point (that is, the tangent point) when the deviation is positive 0.05 mm, and points O2 and E2 represent the center of the raceway and the most concave point (that is, the tangent point) when the deviation is negative 0.05 mm. ), the distance OO between the two centers of the left and right raceways in the direction o...
