Description

Technical Field

[0001] The utility model relates to the technical field of yaw brakes, in particular to a waste oil pipe oil receiving device for a yaw brake. Background Art

[0002] The yaw system of a wind turbine is composed of a yaw brake, a yaw brake disc, a yaw bearing, a yaw drive device, a yaw hydraulic circuit and other parts. When the yaw brake disc has a lot of tooth surface oil, the tooth surface oil is mixed with dust and debris and adheres to the friction plate of the yaw brake, causing the friction plate surface to be uneven. A large impact is generated at the moment of starting yaw or yaw braking, triggering vibration over-limit, affecting the safety and reliability of the wind turbine, reducing the availability of the wind turbine, reducing power generation, and increasing the workload of production personnel. In order to reduce the occurrence of vibration over-limit failures, it is very necessary to grind the impurities on the surface of the yaw brake friction plate and install a yaw drive gear oil plate;

[0003] The above-mentioned existing technical solutions have the following defects: the device has the defect of being inconvenient to absorb oil when in use. The traditional yaw brake waste oil pipe oil receiving device generally directly receives the waste oil, which will cause the waste oil to adhere to the inner wall of the oil receiving pan, increasing the difficulty of cleaning. At the same time, when the oil receiving pan is full of oil, the staff generally needs to take a wrench and turn the bolts to disassemble the oil receiving pan before the waste oil in the oil receiving pan can be cleaned out. This not only increases the cumbersomeness of the operation, but also slows down the cleaning efficiency, thereby reducing the convenience of the device. Utility Model Content
