Problems solved by technology
[0004] Although the existing test methods are simple and easy to implement, the consistency between the test results and the actual application is poor
The most important thing is that the simulation of the test system is not good, and the braking noise generated by the vibration of the actual system cannot be measured

Embodiment Construction
[0019] Below by specific embodiment the present invention is described in further detail:
[0020] Such as figure 1 with figure 2 As shown, the base 1 is fixed with a central shaft 5 and fixed shafts 11 arranged in six equal parts with the center of the central shaft 5 as the center of a circle. The bearing 12 and the turntable 6 are sleeved on the central shaft 5 . The backup roller 2 is fitted on the fixed shaft 11 . The supporting roller 2 supports and guides the ring gear 3 so that the ring gear 3 can only rotate horizontally. The turntable 6 is triangular, with the central shaft 5 as the center, and the three corners are respectively equipped with driving gears 7 meshing with the ring gear 3 . Each drive gear 7 is driven by a planetary reducer 8 and a motor 14 . The motor 14 adjusts the speed and changes the direction of rotation through the frequency converter. One corner of the turntable 6 is extended, the end is connected with the load cell 9 , the other end of ...

A wind power yaw brake test bench mainly consists of a base (1), a support roller (2), a ring gear (3), a brake disc (4), a central shaft (5), a turntable (6), and a drive gear (7 ), a reducer (8), a load cell (9) and a brake under test (10), the present invention adopts a brake disc with a size of 1:1 with the wind turbine yaw brake and a similar installation method. The brake disc can rotate 360°, which is completely different from the reciprocating motion of the existing test device. Solid and very good simulation. In addition to testing the braking characteristics of the yaw brake, it can also truly test the vibration and noise during the braking friction process. The simulation is even better when mounted on a wind turbine tower. The test bench has the advantages of simple structure, convenient replacement of brakes and brake discs, stable and accurate measurement of braking force, etc.
Description
Technical field: [0001] The patent of the invention relates to a wind power generator yaw brake test bench, which belongs to the field of wind power testing. Background technique: [0002] The yaw brake is a key component for wind turbines to control the direction of the rotor. The yaw brake clamps the brake disc and frictionally holds the impeller in the desired orientation. [0003] In order to ensure the reliability of the yaw brake, its performance and wear life must be sample tested. The existing test method is to use a reciprocating iron plate to replace the brake disc, push and pull the iron plate to reciprocate with a hydraulic cylinder, and the yaw brake clamps the iron plate to generate braking force. The braking force depends on the force between the oil cylinder and the iron plate. detected by the sensor. [0004] Although the existing test methods are simple and easy to implement, the consistency between the test results and the actual application is poor. T...
