Description
Technical Field
The utility model relates to a machining center's auxiliary assembly, in particular to harmonic speed reducer ware that accurate revolving stage was used.
Background
The harmonic gear reducer has the advantages of high precision, high bearing capacity and the like, can effectively reduce the area of a field, and is convenient for assembly between the harmonic gear reducer and other mechanisms.
The harmonic gear reducer is a speed reducer, which is composed of three basic components: the flexible gear comprises a fixed internal gear, a flexible gear and a wave generator which enables the flexible gear to deform in the radial direction.
Current machining center all need set up the revolving stage, and the revolving stage rotates through the harmonic reduction gear, and consequently, the revolving stage needs carry out fixed connection with the harmonic reduction gear, and current assembly mode is during the output shaft embedding revolving stage of harmonic reduction gear, then carries out fixed connection through the fixed pin, and at first machining center space is limited, can't carry out the application of force to the fixed pin and fix, and secondly because both are interference fit, produce relative slip after long-time easily.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a harmonic speed reducer ware that accurate revolving stage was used solves harmonic speed reducer ware and the fixed problem of revolving stage installation.
The technical scheme is as follows: the utility model relates to a harmonic reducer for a precision turntable, which comprises a shell; the flexible gear is embedded with a flexible bearing, the flexible bearing is embedded with a hollow wave generator, the radial surface of the output end of the wave generator is provided with an output flange, the output flange is fixedly connected with the output rigid gear, and the output flange rotates along with the output rigid gear.
Furthermore, a first bearing is arranged between the output flange and the wave generator.
