Problems solved by technology

[0004] Flexible gears are flex splines, which are thin-walled cup-shaped, thin-walled cylindrical or flush-embedded, etc. There is a ring gear outside the open end of the thin-walled cylindrical flexible gear. The flexible gear is deformed under the forced deformation of the wave generator, and Driven by the wave generator to produce the meshing movement of the staggered teeth, it is prone to damage during long-term operation under such complex force conditions, which will affect the service life of the harmonic reducer

Abstract

The invention discloses a flexible gear for a harmonic reducer and a manufacturing method therefor. The flexible gear comprises a thin-wall cup body and a flexible ring; the flexible ring is arranged on one side of an opening of the thin-wall cup body; an outer gear ring is arranged on the side face of the outer circumference of the thin-wall cup body; cavities are evenly formed in the flexible ring; elastic bodies are arranged in the cavities; through holes communicating with the cavities are evenly formed in the end face of the flexible ring; and plugs are arranged in the through holes. The method comprises the steps of pouring device installation, pouring molding, cooling demolding, end cover installation, and heat treatment. A wave generator can directly act on the flexible ring, and the flexible ring drives the outer gear ring and the thin-wall cup body to rotate, so that the service life of the flexible gear can be prolonged, the flexible gear is not prone to damage, and long-term operation under various complex conditions is met; the manufacturing method is simple in step, synchronous pouring molding of multiple flexible gears can be achieved, the machining efficiency is improved, the machining precision and quality of the flexible gear can be improved, the strength of the flexible gear is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a flexible gear for a harmonic reducer and a manufacturing method thereof. Background technique [0002] Harmonic reducers have the characteristics of high precision, high torque, low vibration and fast response, so they are widely used in different fields such as industrial robots, mechanical equipment, aerospace, communication equipment, and optical equipment. Due to its high transmission precision, high efficiency, stable transmission, and small size, the harmonic reducer has obvious advantages when applied to some joints of robots. [0003] The harmonic reducer is composed of a flexible gear, a rigid gear and a wave generator. The motion or power transmission is under the action of the wave generator, which forces the flexible gear to produce elastic deformation and interacts with the rigid gear to achieve the purpose of transmission. , so the flexible gear is the core basic component of the harmonic reducer.
