Outside contacts with the outside pin of the inscribed gearing forma epicyclic gear and the said inscribed gearing forma epicyclic gear formation manner null of the pin hole

摘要

PURPOSE: To form the contact surface between the external gear of an internal meshing planetary gear device and an external pin at a low cost so as to improve the performance and prolong the service life. ;CONSTITUTION: An internal gear 10 is made of aluminum expanded material, and the internal peripheral surface of a hole 13 for an external pin is formed with axial minute rugged grooves, and the diameter of the external pin hole ia made larger than the diameter of the external pin, and the external pin 11 comprises a hardened steel bar, the external surface of which is mirror finished less than 1m in surface roughness, and the rugged grooves of the external pin hole is rolled by the external pin to smooth the peripheral direction roughness of the external pin hole when driving force is transmitted.;COPYRIGHT: (C)1994,JPO&Japio
