Description

Technical Field

[0001] The utility model relates to the field of wind power generation equipment, in particular to a test fixture for a yaw reducer. Background Art

[0002] A yaw reducer is a reducer used to adjust the direction of a wind turbine nacelle, which reduces speed and increases torque. Usually, multiple reducers work simultaneously, and their output gears mesh with the large gear that carries the entire nacelle, driving the entire nacelle to deflect.

[0003] The yaw reducer is small in size, has a high reduction ratio, and a large load capacity. However, it is inconvenient to replace and has a high replacement cost. Its performance directly affects the direction adjustment of the wind turbine nacelle, and thus affects the power generation efficiency of the entire unit. Therefore, performance testing is required before the product is put on the shelf to ensure that the reducer is working properly. Utility Model Content
