Simulated reality detection device for variable pitch bearing test

Abstract

The invention relates to the technical field of variable-pitch bearing detection, in particular to a reality-simulated detection device for variable-pitch bearing testing. The device comprises a fixing device and a rotating device arranged on one side of the fixing device. The fixing device comprises a fixing mechanism, and a positioning structure is arranged on one side of the fixing mechanism; the fixing mechanism comprises a fixing seat, and the side wall of the fixing seat is fixedly connected with a plurality of fixing rings which are arranged in a normally annular shape; the positioning structure comprises a pressing ring, and the bottom end of the pressing ring is attached to the top end of the fixing ring. According to the invention, the service life of several variable pitch gears of different specifications can be simultaneously and synchronously tested, and compared with a common testing device, when the variable pitch gears are driven to rotate integrally, the inner ring and the outer ring rotate relatively, so that the device is more suitable for an actual use scene, obtained data is more suitable for reality, and the testing efficiency is improved. And an operator can conveniently compare and optimize different variable pitch gears according to the data.

Description

technical field [0001] The invention relates to the technical field of pitch bearing detection, in particular to a real-simulating detection device for pitch bearing testing. Background technique [0002] The function of the pitch bearing is to rotate the blades installed on the hub, the outer ring is connected to the hub through bolts, and the inner ring is connected to the blades. When the wind speed is too high or too low, the angle of attack of the airflow on the blade is changed by adjusting the blade pitch, thereby changing the aerodynamic torque obtained by the wind turbine and keeping the power output stable, which plays an important role in the wind turbine. Once it is damaged during use, it will bring extremely serious economic losses and a series of consequences, so the test of the service life of the pitch gear is very important, and the common test device cannot well imitate the real use of the pitch gear. Therefore, the data obtained are only the life of the c...

Problems solved by technology

When the wind speed is too high or too low, the angle of attack of the airflow on the blades can be changed by adjusting the pitch of the blades, thereby changing the aerodynamic torque obtained by the wind turbine and keeping the power output stable, which plays an important role in the wind turbine. Once it is damaged during use, it will bring extremely serious economic losses and a series of consequences, so the test of the service life of the pitch gear is very important, and the common test device cannot well simulate the real use of the pitch gear Scenarios, so the data obtained are only the life of the conventional number of rotations, which cannot well reflect the life of the pitch gear under normal use and the performance of the wind when the wind is complex.
