Abstract

A wind turbine generator variable pitch bearing oil collecting tank and recovery system comprises an oil collecting tank body, the oil collecting tank body is connected with a connecting cover at the upper end, a bearing connector used for being connected with a variable pitch bearing is arranged at the upper end of the connecting cover, an oil inlet one-way valve is arranged in an oil passing pipeline, and an oil passing pipe connected with the bearing connector is arranged on the inner side of the connecting cover. A limiting block is arranged at the tail end of the oil pipe, an oil squeezing piston which is in sliding contact with the oil pipe and the inner side of the oil collecting tank body and is sealed is arranged at the upper end of the limiting block, a first communicating hole communicating inside and outside is formed in the top end of the oil collecting tank body, an overflow hole is formed in the bottom of the oil collecting tank body, and an oil outlet one-way valve is arranged in the overflow hole. Through combination of the oil passing pipe and the oil squeezing piston and cooperation of the oil inlet one-way valve and the oil outlet one-way valve, lubricating oil is gathered in the tank when the tank is not full, the lubricating oil overflows from the overflow hole when the tank is full, and rapid recovery and automatic recovery of the lubricating grease in the tank can be achieved through cooperation of the first communication hole, the second communication hole and the oil squeezing piston.

Description

technical field [0001] The invention relates to the technical field of wind power generation auxiliary equipment, in particular to an oil collection tank and a recovery system for pitch bearings of wind turbines. Background technique [0002] The pitch system in the wind turbine is an important adjustment structure to realize the relative orientation of the blades and the wind direction. The pitch bearing is used as the support carrier for the pitch control and the blade, and bears the connection between the hub and the blade of the generator set and the rotation load adjustment function. , is an important part of the pitch system. [0003] The normal operation of the pitch bearing needs to use grease to fully lubricate the raceway. The grease is injected into the raceway by pressure injection. Usually, an oil collecting bottle is installed on the bearing, and the oil collecting bottle communicates with the raceway. While the oil collecting bottle collects the grease, it al...
