Abstract

The invention discloses a gear box of a direct cooling reducer, which includes a cooling oil pump, a valve, an oil pipe and a nozzle. The bearing oil pipe is connected to the cooling oil pump through a bearing valve, and the bearing oil pipe is fixed on the outer side of the bearing. The bearing oil pipe is a telescopic casing. Both the outer oil pipe and the inner oil pipe are equipped with a number of oil discharge holes, and the outer oil pipe is stretchable relative to the inner oil pipe; the gear oil pipe extends to the inside of the gearbox through the gear valve; the end of the gear oil pipe is connected to the nozzle, and the nozzle is aimed at the circumference of one of the gears to spray cooling oil . In the gear box of the reducer of the present invention, the cooling oil channel is directly arranged on the box body of the gear box, and the gear box and the gears are cooled simultaneously. In addition, the telescopic bearing oil pipe is used to cool the bearing, which is convenient for controlling the cooling of the bearing and reduces its cooling cost. It ensures that the wind turbine can still guarantee a long service life when it is used in a relatively high temperature environment, and reduces operation and maintenance, and reduces its use cost.

Description

technical field

[0001] The invention relates to the technical field of reducer gearboxes, in particular to a direct-cooling reducer gearbox. Background technique

[0002] The wind turbine gearbox lubrication and oil cooling system focuses on the following three functions:

[0003] (1) Fully lubricate the gears and bearings inside the gearbox to prolong the life of the gearbox;

[0004] (2) Continuously monitor the oil temperature of the gearbox and perform cooling or heating to ensure that the oil temperature of the gearbox remains within the optimal working range;

[0005] (3) Filter impurities in lubricating oil.

[0006] However, during its use, especially when the ambient temperature of the wind turbine unit is high and the load is high, the unit often reports an overtemperature fault of the cooling water of the gearbox and the unit shuts down. Special personnel are required to carry out regular inspection and maintenance. Contents of the invention
