Abstract

The invention discloses a harmonic reducer tooth surface machining method. A rigid wheel is machined through a conjugate tooth profile electric spark generating method. The machined rigid wheel is connected with a positive electrode of an electric spark power supply; and a flexible gear is connected with a negative electrode of the electric spark power supply, a flexible bearing and a wave generator are arranged in the flexible gear, the transmission ratio among the flexible gear, the rigid gear and the wave generator is controlled through a transmission chain or a harmonic reducer of a machining device, and the tooth portion of the flexible gear comprises a conical tooth section, a finish machining section and a running-in section. The conjugate tooth profile electric spark generating method is adopted for machining, the transmission ratio among the flexible gear, the rigid gear and the wave generator is consistent with the design of a harmonic reducer, the obtained tooth profile of the rigid gear is a no-load conjugate tooth profile conforming to the effect of no theoretical error, and the conjugate tooth profile under the load condition is obtained through loading running-in.

Description

technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to a method for processing tooth surfaces of harmonic reducers and a processing device thereof. Background technique [0002] The structure of the harmonic reducer mainly includes a wave generator, a flexible bearing, a flexible wheel, and a rigid wheel. Among them, the flexible spline is a flexible external gear, and the rigid spline is a rigid internal gear. The harmonic reducer has the advantages of compact structure, small size, light weight, large transmission ratio and carrying capacity, and high transmission precision. The motion or power is usually input by the wave generator, the rigid spline is stationary, and the motion is output by the flexible spline; or the flexible spline is stationary, and the motion is output by the rigid spline. [0003] When the harmonic reducer without any error is working, the flex spline is deformed at a uniform speed by the action ...
