Problems solved by technology

As a result, the number of meshing teeth is small, the transmission accuracy is low, and the number of teeth that can bear the load is also small; the teeth will have sudden changes in the meshing and meshing, making the output unstable and impactful; and its service life is also short

Abstract

The invention discloses a harmonic speed reducer with a flexible felly. The harmonic speed reducer comprises a wave generator, a flexible gear and the felly, wherein the flexible gear comprises a gear body and a gear ring; the gear body is substantially disc-shaped and concentrically arranged on the outer circumference of the gear body; first teeth are formed on the outer circumference of the gear ring; the felly comprises a felly body and a felly ring; the felly body is circular; the felly ring is arranged on the end surface of the felly body; second teeth are formed on the inner circumference of the felly ring; the wave generator is arranged on the inner circumference of the gear ring; the outer circumference of the gear ring is arranged on the inner circumference of the felly ring; the first teeth are meshed with the second teeth; and the felly ring is deformed along with the gear ring. According to the scheme, the number of meshed teeth is relatively large, the transmission precision is relatively high, the output is stable, an impact is not generated, and the service life is long.

Description

technical field [0001] The invention relates to an improvement of a harmonic reducer, in particular to a harmonic reducer with a flexible outer wheel, which has more meshing teeth, higher transmission precision, stable output, no impact and long service life, belonging to reducers technology field. Background technique [0002] The reducer is a power transmission mechanism that uses the speed conversion of the gear set to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque mechanism. There are many types of reducers with different models, and different types have different uses. Among them, the harmonic reducer is a new type of reducer developed by using the principle of planetary gear transmission. The unique advantages of small size, light weight, stable transmission and high transmission precision make harmonic reducers widely used in electronics, aerospace, robotics and other industries. [0003] Existing harmon...
