Embodiment 1

[0017] Such as figure 1 , figure 2 As shown, it is a structural schematic diagram of the tested crankshaft, the spline 8 is located at the left end of the crankshaft 7, and the center of the spline tooth groove is aligned with the eccentric line of the crankshaft.

[0018] The invention is a measuring instrument for measuring the angular deviation between the crankshaft spline tooth groove center and its eccentric connection line. Such as image 3 , Figure 4 Shown is the structural schematic diagram of the measuring instrument for measuring the angular deviation between the spline tooth groove center of the crankshaft and the line connecting the eccentricity. The mechanical part consists of a spline sleeve 1 and an eccentric sleeve 2. The eccentric sleeve 2 is used to locate the eccentric reference of the crankshaft during measurement. The spline sleeve 1 is used to cooperate with the spline 8 during measurement. One end of the spline sleeve 1 is embedded in the eccentric...

Abstract

The invention discloses a measuring apparatus for angular misalignment of a crankshaft spline tooth slot center and an eccentric connecting line thereof. The measuring apparatus is characterized by comprising a spline sleeve, wherein the spline sleeve is connected with an eccentric sleeve; and a circular grating sensor is arranged outside the connected part of the spline sleeve and the eccentric sleeve. The measuring apparatus has such characteristics as high and reasonable measuring efficiency and the like.

Description

technical field [0001] The invention relates to a measuring instrument for measuring the angular deviation between the spline tooth groove center of a crankshaft and its eccentric connection line, belonging to the field of reducers. Background technique [0002] When the gears of the involute planetary reduction stage are assembled in the RV reduction mechanism (note: the RV reduction mechanism is a reduction mechanism composed of an involute planetary reduction and a cycloid pin-tooth reduction), in order to meet the gear matching requirements of the sun gear and the planetary gear And installation needs, in addition to requiring the splines of the sun gear, planetary gear and crankshaft-planetary gear to have even teeth, the relative angular position relationship between the splines on the crankshaft and the eccentric line of the crankshaft is also required. Theoretically, the centers of the spline slots on the crankshaft must line up with the crankshaft eccentric line. H...
