Example Embodiment

[0009] Example 1

[0010] The gear and sprocket are seated on the worktable, and the position is positioned through the groove, guide bar and limit block of the worktable. The gear and sprocket are installed in the gear and sprocket seat, and the center is positioned through the outer circle. The center is only used for support axis. The bottom bracket is fixed with the gear and sprocket seat. By making pin holes on the bottom bracket at an appropriate angle, and inserting the positioning pin, the positioning pin is aligned with the alignment mark hole of the gear and sprocket to ensure the gear and sprocket. Angular positioning accuracy.

[0011] Due to the above technical scheme, the gear and sprocket are centered through the outer circle. When the shaft is press-fitted, the inner center will not affect the positioning accuracy of the gear and sprocket, so that the shaft can be smoothly installed in the wheel. Equipped with a pin hole for angle positioning on the bottom bracket...

Abstract

The invention provides a method for positioning the angle of a gear and a sprocket, which comprises the following steps: the gear and the sprocket are seated on the workbench, and the position is positioned through the groove of the workbench, the guide bar and the limit block; the gear and the sprocket are installed Insert the gear and sprocket seat, and use the outer circle for center positioning, and the top is only used to support the shaft; the bottom bracket is fixed with the gear and sprocket seat, and the positioning pin is installed by making a pin hole at a suitable angular position on the bottom bracket. The beneficial effects of the invention are: effectively reducing the operating intensity of workers, improving the press-fit cycle time, and ensuring the smooth press-in of the shaft.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method for angular positioning of gears and sprockets. Background technique [0002] In the existing technology, the press-fitting of the balance shaft needs to ensure the matching angle between the shaft, the gear and the sprocket. In this existing operation mode, the operation is complicated. It is necessary to manually identify the approximate position and push the meshing wheel to the meshing position, and the manual operation is complicated. , higher requirements for workers. And when the shaft is press-fitted, it is necessary to push out the positioning top first. There is difficulty in manual alignment operation, easy to misplace, and the operation time is long, which affects the beat. When the shaft is ejected from the top, the gear and sprocket will have a slight displacement, so that the shaft cannot enter the hole of the gear and sprocket smoothly, and it is easy to get ...
