What is the assembly distance of the gear, and what should be the tolerance for its size?

Reply:

Assembly distance:The axial distance from the apex of the cone of the bevel gear to the positioning surface (installation reference surface).In English, the assembly distance is called Locating distance (Mounting distance).

The assembly distance is an important dimension that affects gear tooth contact and backlash.

In order to obtain proper backlash and gear tooth contact, the tolerance should be as close as possible to zero.

For the tolerance of the reference size (allowable difference is close to 0), js7~js9 are recommended.If you have more questions or related processing requirements, please consult EP free of charge.
