Yaw bearing testing device and method

Abstract

The invention discloses a testing device and a method of a yaw bearing. The testing device of the yaw bearing comprises a bearing under test, a test accompanying bearing, a plurality of sets of loading devices, a loading arm, a transition section, a base, and a driving device, wherein the plurality of sets of loading devices are connected with the loading arm to provide axial loading force, radial loading force, and turning torque for the bearing under test, the lower end part of the loading arm is connected with an inner ring of the test accompanying bearing, an outer ring of the test accompanying bearing is connected with the upper end part of the transition section, the lower end part of the transition section is connected with an outer ring of the bearing under test, an inner ring of the bearing under test is connected with a base, and an output gear of the driving device is engaged with an outer ring gear of the bearing under test to provide rotating driving force for the bearing under test. The testing device and the method of the yaw bearing can reduce device cost and improve testing accuracy.

Description

technical field [0001] The invention relates to wind power generator technology, in particular to a yaw bearing testing device and method. Background technique [0002] like figure 1 As shown, the tower 2a of the wind power generating set is connected to the impeller 1a through the yaw bearing 3a, and the direction of the impeller 2a is adjusted to the wind direction at all times through the yaw bearing 3a, so as to provide the maximum wind kinetic energy for the impeller 2a. If there is a problem with the yaw bearing 3a, it is necessary to replace the yaw bearing 3a after hoisting the wind turbine to the ground, which will affect the normal operation of the wind turbine. Therefore, the performance test of the yaw bearing 3a is an important link in the research and development process. It is necessary to simulate the actual working condition load of the yaw bearing 3a through the yaw bearing test device, and then check the various technical indicators of the yaw bearing 3a,...
