Talk about the gear assembly clearance requirements of the reducer



相互啮合圆栓齿轮副的轴向错位,应按齿宽大小规定错位量检查。 The main feature of the worm gear reducer is the reverse self-locking function, which can have a large reduction ratio. The input shaft and the output shaft are not on the same axis, and they do not mesh with each other on the same plane. Check the displacement according to the tooth width.

When the gear is assembled, the end face of the gear reference surface and the end face of the shaft shoulder or the positioning sleeve should closely fit, and the perpendicularity requirements of the reference end surface of the gear and the axis should be maintained.

3 倍,铅条的长度不应小于 5 个齿距,沿齿宽方向应均匀放置至少 2 根铅条。 When checking the gear meshing clearance by the lead pressure method, the diameter of the lead bar should not exceed 3 times the gap , the length of the lead bar should not be less than 5 pitches, and at least 2 lead bars should be evenly placed along the tooth width direction .

When assembling an involute cylindrical gear pair with an axis parallel to the position and an adjustable structure, the limit deviation of the center distance should meet the requirements of the random technical documents.

Gears and gears, worms and worm gears should be checked after assembly. Its rotation should be smooth, flexible and without abnormal sounds;

The percentage of contact spots that check the meshing of the transmission gear by the coloring method shall meet the requirements.

The above is related to the reducer, I hope it can be helpful to you
