Description

Technical Field

[0001] The utility model relates to the technical field of oil pump supports, in particular to a shock-absorbing oil pump support for a wind power gear box. Background Art

[0002] The blades of a wind turbine generate power through their own rotation, which in turn drives the rotation of the gearbox. The gears in the gearbox achieve power transmission by meshing with each other. After the power from the wind wheel is transmitted to the gearbox, it is transmitted to the generator to generate electricity. The function of the gearbox is to convert the power generated by the wind wheel into power suitable for power generation through the rotation of internal gears. The gearbox can also transmit mechanical energy to the generator. In a wind turbine generator set, the gearbox oil pump is a key component for reducing the speed and increasing the torque. It can transmit the high-speed rotating gearbox output shaft to the generator main shaft to ensure that the entire unit can run smoothly and efficiently. The oil pump is driven by a pair of gears, and the power is transmitted from the input shaft to the output shaft through the meshing of the gears. On the output shaft, the blades of the oil pump will generate negative pressure when rotating, thereby sucking in oil and discharging it from the inside. This process will continue to provide the required lubrication and cooling for the gearbox and generator.

[0003] The vibration caused by the operation of the oil pump's own driving motor and the water hammer will cause damage to the pipeline and support seat. Installing shock absorbers will greatly reduce the damage caused by vibration. The existing oil pump supports of this type are generally not conducive to shock-absorbing support at multiple positions of the oil pump when in use. It is easy to cause continuous vibration when the oil pump is running, and it is not convenient to control and adjust the installation position of the oil pump, which greatly affects the convenience of position adjustment during installation of the oil pump. Long-term vibration can easily cause loosening of the oil pump itself and the connected pipelines. Utility Model Content
