A high-speed and high-power coupling shaft reducer

Abstract

The invention discloses a high-speed and high-power coupling reducer, comprising: a housing, one end of the housing is open, and an input end is arranged on the back and outer side of the housing to rotate away from the central position of the opening, and the input end corresponds to A part of the casing is provided with a sun gear, and a plurality of planetary gear assemblies are arranged symmetrically corresponding to the sun gear in the casing, and a rotating disk is arranged at the opening of the casing, and a rotating disk is arranged on the edge of the rotating disk. The inner ring gear that is meshed with the planetary gear, the center of the side of the rotating disk away from the housing is extended outwards, and an output end coaxially arranged with the input end is provided, and the planetary gear assembly and the inner ring gear can be arranged Two-stage deceleration is formed, so that the rotating disk can decelerate and output power. The planetary gear is installed in the casing through the cantilever assembly. The long run of the gears.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a high-speed and high-power shaft-coupled reducer. Background technique [0002] With the continuous increase of power demand for field engineering construction, the requirements for the floor area and weight restrictions of construction and transportable equipment are also increasing. [0003] The economical requirements of the project require that the construction site occupy a small area, and the equipment going to the site for construction must meet the conditions for land transportation under pressure. [0004] In the construction of shale gas development projects, mechanical reciprocating energy conversion equipment is commonly used, but when its power reaches a certain level, it can no longer meet the restriction requirements of engineering construction; at this time, mechanical rotating turbofan energy conversion equipment has become a more It is an excellent choice.

Problems solved by technology

[0004] In the construction of shale gas development projects, mechanical reciprocating energy conversion equipment is commonly used, but when its power reaches a certain level, it can no longer meet the restriction requirements of engineering construction; at this time, mechanical rotating turbofan energy conversion equipment has become a more It is an excellent choice, because of the continuity of its energy conversion, its advantages in mobile equipment have begun to fully manifest, such as Russian turbofan engine tanks and American littoral combat ships. Advantage

[0005] With the breakthrough of my country's aircraft engine technology and the realization of C919 integrated innovation, the expanded application field of turbofan engine will have a greater development; therefore, higher requirements are also put forward for the reducer in the transmission process, application number 201610919639.9 is a high-speed and high-power coaxial reducer. Due to the large dynamic load carried by its high-speed planetary gear assembly, it is difficult to meet the long-term use requirements of the existing high-speed and high-precision rolling bearings. The life of the rolling bearings in the planetary gear assembly It has become a bottleneck restricting the overall quality improvement of products
