Problems solved by technology

Usually in the process of processing, each flexspline is equipped with a mandrel, and the mandrel is inserted into the inner hole of the flexspline through interference fit, and then the outer circle of the flexspline and hobbing are processed. This method is not conducive to the disassembly of the flexspline , and it is very easy to cause the bottom of the flexspline to bend, which will cause the bottom of the flexspline to crack during operation. For this reason, it is very necessary to design a new tooling for the flexspline from the perspective of facilitating the use of front-line operators and ensuring the performance of the flexspline

Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] see Figure 1 to Figure 2 , a gear hobbing tool for a harmonic reducer flexwheel, including a hydraulic expansion tool 1 installed on a gear hobbing machine, the front part of the hydraulic expansion tool 1 has an expansion part 11, and the expansion part 11 is sleeved with a harmonic reducer flexwheel 2. The hydraulic expansion tooling 1 is fed with hydraulic oil to make the expansion part 11 expand and tighten the harmonic reducer flexwheel 2, and the gear hobbing cutter 3 is arranged above the harmonic redu...

Abstract

The invention discloses a hobbing tool of a harmonic reducer flexible wheel. The hobbing tool comprises a hydraulic expansion tool installed on a gear hobbing machine, an expansion part is arranged onthe front part of the hydraulic expansion tool, a harmonic reducer flexible wheel body sleeves the expansion part, hydraulic oil is introduced into the hydraulic expansion tool to make the expansionpart tightly expand theharmonic reducer flexible wheel body, a hobbing cutter is arranged on the upper part of the harmonic reducer flexible wheel body, and the hobbing part of the hobbing cutter is located on the upper part of the harmonic reducer flexible wheel body and conducts hobbing. In the way, according to the hobbing tool of the harmonic reducer flexible wheel, the hobbing accuracy can beimproved, the positioning effect is good, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a gear hobbing tool for a harmonic reducer flex wheel. Background technique [0002] Flexspline is the key component of harmonic drive, and its dynamic performance determines the performance of its system to a large extent. Because the flexible spline is a thin-walled part, it is always subjected to reciprocating stress during the transmission process, so the processing technology is very strict. Usually in the process of processing, each flexspline is equipped with a mandrel, and the mandrel is inserted into the inner hole of the flexspline through interference fit, and then the outer circle of the flexspline and hobbing are processed. This method is not conducive to the disassembly of the flexspline , and it is very easy to cause the bottom of the flexspline to bend, which will cause the bottom of the flexspline to crack during operation. Therefore, it is very necessary to desig...
