Abstract

The invention discloses a multi-layer high-damping rocker arm type flexible planet carrier which comprises an inner sleeve, an outer sleeve, a planet wheel mounting seat and a two-stage damping structure composed of an inner-layer damping structure and an outer-layer damping structure, the inner-layer damping structure comprises a spline damping ring, and the inner sleeve and the outer sleeve are assembled into a whole in a meshed mode through the spline damping ring. Power is transmitted through the spline damping ring, the outer layer damping structure comprises a honeycomb damping pad, the planet wheel installation base and the outer sleeve are isolated through the honeycomb damping pad, and the planet wheel installation base is connected to the outer sleeve through a pin shaft to form a rocker arm type structure. According to the embodiment, by designing a two-stage damping structure, system vibration is remarkably restrained, and noise is lowered; the rocker arm type planet carrier is designed, so that the coupling performance among the planet wheels is obviously reduced, and the operation stability of the system is improved; under the condition that the machining precision grade is reduced, the movement stability of the system can be kept, and therefore the machining cost is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of planetary gear transmission systems, and in particular relates to a multi-layer high damping rocker arm type flexible planet carrier. Background technique [0002] Due to its large reduction ratio and high power density, the planetary gear transmission system is widely used in various power transmission equipment. However, in practical applications, it is found that due to its complex structure and high processing and assembly requirements, it causes relatively large vibration and noise during actual work. Various solutions have been proposed to solve such problems, including the use of floating sun gears and flexible ring gears, but these solutions lead to other incidental problems, such as structural strength problems and internal buzzing noise problems. Contents of the invention [0003] The technical solution of the present invention mainly solves at least one of the following technical problems: ...
