A hyperboloid is formed by a straight line rotating around a line that is out of it (see figure). Comparing one of the straight lines to the outer busbar of the shaft corresponds to the rotation of the shaft in the hole, and their contact area is a straight line. In theory, as with the gap fit of the ordinary hole and the shaft, the line is in contact with the line, which not only ensures the automatic adjustment of the gear when meshing, but also does not reduce the contact length of the shaft with the hole.
The concept of "hyperbolic holes" was introduced in the design of ordinary planetary gear holes. In the foreign pattern, the inner hole of the planetary gear has a drum shape, and the busbar corresponding to the cylindrical inner hole is an arc having a radius R, so that the planetary gear can automatically adjust the meshing gap when meshing with the side gear on its shaft. Contact area. However, since the contact of the planetary gear hole with the planetary gear shaft is only the middle portion, this accelerates the wear of the planetary gear hole and the gear shaft, and the double curved hole can solve the problem.
