Radial run-out detection alignment mechanism and method at assembling position of rotor shaft end of wind driven generator

Abstract

The present invention discloses a radial run-out detection alignment mechanism and method at an assembling position of a rotor shaft end of a wind driven generator. The problems are solved that the repairing cost is high and the holding time of a test device is long due to respective and independent arrangement of current shaft end radial run-out detection and repairing technologies. The mechanismcomprises a balancing machine, a generator rotor (6) to be detected is arranged on the balancing machine, a pressure cover is arranged at the top end of a support frame of the balancing machine, thepedestal (1) of the balancing machine is provided with a detection dial gauge stand (7) which is provided with a dial indicator (8), the header of the dial indicator (8) is abutted joint the excircleat the assembling position of the rotor shaft end of the generator rotor (6) to be detected, a jack (11) is arranged below the assembling position of the rotor shaft end, and a support copper block (12) is arranged between the top end of an upward output shaft of the jack and the excircle at the assembling position of the rotor shaft end of the generator rotor to be detected. The radial run-out detection alignment mechanism and method at the assembling position of the rotor shaft end of the wind driven generator achieve the purpose of synchronous completion of inspection and correction to improve the utilization efficiency of the balancing machine.

Description

technical field [0001] The invention relates to a radial runout detection mechanism of a shaft end of a motor, in particular to a radial runout detection and straightening mechanism of a shaft end assembly connection of a wind power generator rotor. Background technique [0002] The characteristic of the 2MW wind turbine rotor structure is that the axial dimension is much larger than the radial dimension. The assembly process of the wind turbine rotor is as follows: after the rotor shaft is accepted at the factory, it has to undergo multiple processes such as heat-fitting iron core, embedding wire, and dipping paint. In these processes, it is easy to cause slight deformation in the radial direction of the assembly part of the shaft end. Therefore, after the assembly of the 2MW wind turbine rotor is completed, a radial runout test is required. The radial runout detection test is based on the central axis of the rotor bearing gear, and detects whether the concentricity of the ...
