Abstract

The invention relates to a wind driven generator coupler slipping torque calibration test bed and calibration method which is particularly suitable for stimulating actual working environment to conduct a slipping torque calibration test when a wind driven generator coupler is developed and leaves a factory. The test bed is mainly composed of a rack, a base plate, a torque loading mechanism, a torque output detecting mechanism, a hydraulic system and a computer control system. When the test is conducted, firstly the wind driven generator coupler is installed on the test bed, a hydraulic swing oil cylinder is started, the wind driven generator coupler is loaded by the torque loading mechanism, the load is acted on a tension and pressure sensor through the torque output detecting mechanism, transmission torque is obtained through indirect detection, and when a torque limiter of the wind driven generator coupler slips, the computer control system monitors that torque in a torque-angle curve suddenly changes, and the torque is the slipping torque of the wind driven generator coupler. The wind driven generator coupler slipping torque calibration test bed and calibration method is also suitable for slipping torque calibration of couplers and transmission shafts of other types.

Description

technical field

[0001] The invention relates to a wind turbine coupling slip torque calibration test bench and a calibration method, which are especially suitable for simulating the actual working environment for the slip torque calibration test in the development and delivery of the wind turbine coupling. Background technique

[0002] The wind turbine relies on the wind to drive the propeller to rotate, increases the speed through the gear box, and connects the output shaft of the gear box and the rotor shaft of the generator through the wind turbine coupling to convert the wind energy into electrical energy. When the transmission torque of the wind turbine exceeds its limit, the torque limiter on the coupling of the wind turbine generator slips to protect it from damage. During the development and delivery of the wind turbine coupling, the slip torque needs to be calibrated to meet the stable operation requirements of the wind turbine system. The problems existing in the ...
