RV reducer based on particle damping shell

Abstract

The invention discloses an RV reducer based on a particle damping shell. The RV reducer comprises the shell and a cycloidal gear. Holes are punched in the upper portion and the lower portion of the edge of the shell, abrasion-resistant rubber interlayers are embedded, a certain quantity of damping particles are packed in the interlayers, and then the two ends are sealed. According to the RV reducer, a damping effect is achieved through collision between the damping particles on the edge of the shell as well as between the damping particles and the inner wall of the shell, and vibration caused by sudden stopping and sudden starting in the working process of the RV reducer is attenuated in time. The RV reducer is reasonable in structure, good in damping effect, and capable of prolonging the service life of main parts and components, and the transmission stability and accuracy of the RV reducer are improved.

Description

technical field [0001] The invention belongs to the field of precision reducers, and in particular relates to an RV reducer based on a particle damping shell. Background technique [0002] As an emerging transmission form, RV transmission is based on the traditional pendulum planetary transmission, and has many advantages: large transmission ratio range, high transmission efficiency, small size, light weight, strong bearing capacity, high motion precision, long life, output The mechanism is rigid. At present, RV reducers are widely used in industrial robots, especially in the field of robots that have high requirements for transmission accuracy. [0003] Some disadvantages of domestic RV reducer: 1. Lack of precision machining equipment, RV reducer gear precision requirements are high, but domestic manufacturers lack corresponding manufacturing equipment, and there is a technical blockade; 2.

Problems solved by technology

[0003] Some disadvantages of domestic RV reducer: 1. Lack of precision machining equipment, RV reducer gear precision requirements are high, but domestic manufacturers lack corresponding manufacturing equipment, and there is a technical blockade; 2. RV reducer is prone to vibration during operation and noise, especially the sudden stop and start of industrial robots during work will produce impact, causing a series of problems such as the collision between the needle roller and the upper and lower planetary frames, and the shell.

At present, domestic RV reducers will generate vibration and noise during operation, resulting in unstable operation. Compared with imported products, their service life, transmission accuracy, and dynamic characteristics are all poor.
