Multiple eccentric shaft processing method and using counterbalance and eccentric sleeve

Abstract

The invention discloses a processing method of multiple eccentric shaft; lengthened ends are arranged on both ends of the multiple eccentric shaft; after that a counterbalance is arranged at the position of eccentric crosspiece, and a reference crosspiece is processed, then counterbalance is dismounted; a eccentric sleeve is arranged at the lengthened end, and an eccentric crosspiece is processed; finally the lengthened end of the multiple eccentric shaft is removed, and a multiple eccentric shaft is obtained. The invention also discloses the counterbalance use in the method, comprising a balance section and a fixation section; the balance section and the fixation section can clasp the eccentric crosspiece after being installed. The invention also disclosed the eccentric sleeve use in the method, comprising a lengthened end hole and a processing hole; the axial line of the lengthened end hole is in parallel with the axial line of the processing hole, the eccentric crosspiece is processed by taking the axial line of the eccentric crosspiece as the processing axial line. The counterbalance and the eccentric sleeve provided by the invention has simple structure, and is easy to make; and relative high precision can be easily achieved; the processing method of the multiple eccentric shaft of the invention has simple steps, and the multiple eccentric shaft with relative high precision can be made with convenience and rapidness.

Description

technical field [0001] The invention relates to a processing method for multiple eccentric shafts. The invention also relates to a balance weight for multi-eccentric shaft machining. The invention also relates to an eccentric sleeve for machining multiple eccentric shafts. Background technique [0002] The processing of multiple eccentric shafts has long been a confusing problem. From the perspective of space and use, this type of shaft system is composed of three or more centerlines composed of various outer circular shafts. There is no keyway on the circle (for positioning options), and the phase error between the eccentricities of each gear is less than 2°. To realize the three conditions of multi-eccentricity, keyless positioning and small phase error at the same time, the process is not very good and Economical processing method. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method for mult...
