Fan speed-increasing gearbox test bed capable of achieving pose controlling and spindle loading

Abstract

The invention belongs to the technical field of the dynamic property and the reliability of a speed-increasing gearbox transmission system of wind power equipment, and particularly relates to a fan speed-increasing gearbox test bed capable of achieving pose controlling and spindle loading. The test bed comprises a pose simulation platform and a spindle loading simulation platform. According to the pose simulation platform, six post loading driving devices simulate the spatial displacement variations of six degrees of freedom of the test bed in an actual wind load. According to the spindle loading simulation platform, six magnetic field loading devices simulate alternating bending loads and axial thrust loads, and the alternating bending loads and the axial thrust loads are borne by a spindle in an actual wind load. A parallel mechanism basic structure is used, the position and the pose of the six degrees of freedom of the wind power speed-increasing gearbox can be simulated under the action of the wind loads, the non-contact type spindle is used for achieving electromagnetic loading, and the axial thrust loads and the alternating bending loads borne by the spindle in an actual working condition can be truly simulated.

Description

technical field [0001] The invention belongs to the technical field of dynamic performance and reliability of a speed-up gearbox transmission system for wind power equipment, and in particular relates to a wind power speed-up gearbox test bench capable of realizing six-degree-of-freedom position and attitude control in space and non-contact loading of a main shaft. Background technique [0002] Wind power equipment "large-scale, long life and high reliability" is the development trend of the global wind power equipment manufacturing industry, and it is also a common technical challenge. The service conditions and loads of wind power equipment are subject to the impact of irregular wind loads and even strong gusts. They are also subjected to extreme heat and cold and extreme temperature differences all year round, as well as wind, sand and offshore smog, which can easily cause key components to fail. According to the statistics of wind power equipment failures at home and abr...

AI Technical Summary

Problems solved by technology

At present, the wind turbine test bench widely used in engineering is a motor-driven reducer that is directly connected to the transmission system of the wind turbine. This test bench can only provide the torque required by the wind turbine, but cannot truly simulate other loads of the actual wind load on the main shaft. The main shaft at the input end of the fan transmission chain also needs to bear axial thrust and bending moment load, so it is the general trend to apply non-contact loads to the main shaft of the transmission chain
