Problems solved by technology

If the grease is not cleaned and replaced in this state, the hard metal particles are mixed in the running bearing, and the rollers press the hard particles into the raceway, causing the surface of the raceway to bulge, which in turn causes more metal particles to fall off. Long-term operation will eventually cause the contact surface of the roller raceway to wear

Abstract

The invention belongs to the technical field of fans, and particularly relates to a lubricating oil circulating system for a heavy-load bearing of a wind generating set. Comprising a spindle, a main bearing, a circulation triggering device, a piston rod and a grease circulation device. A main bearing is arranged on the main shaft, and an oil injection hole and an oil discharge hole are formed in the main bearing; an oil injection pipe of the grease circulating device is connected with the oil injection hole, and an oil suction pipe of the grease circulating device is connected with the oil discharge hole; a circulating trigger device is arranged on the periphery of the main shaft; the grease circulating device is connected with one end of the piston rod; a bull eye wheel is arranged at the other end of the piston rod and is used for being in contact triggering with a circulating triggering device; the piston rod is driven to reciprocate through rotation of the main shaft and contact of the piston rod and the circulation triggering device, the grease circulation device sucks lubricating oil flowing out of the main bearing, and the lubricating oil flows back to a main bearing oil injection hole after being filtered to supplement lubrication. Main shaft displacement sensors are arranged on the upper side and the lower side of the main shaft. Circulating flow lubrication of the bearing can be achieved, and the service life of the main bearing is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to a heavy-duty bearing lubricating oil circulation system of a wind turbine. Background technique [0002] According to the statistics of relevant enterprises, 1.5MW doubly-fed wind turbines have main bearing wear and backward movement of the transmission chain within 2-3 years of grid-connected operation. This phenomenon has not attracted enough attention from the owners. Major equipment failures, such as bearing rollers falling off and bearing outer ring breaking, led to the shutdown of the wind turbine. [0003] To repair such faults, it is necessary to hire a crane to replace the drive chain assembly in the air. The on-site construction is affected by weather, environment, personnel quality and other aspects, and it is difficult to ensure the quality of the assembly. If the newly replaced drive chain assembly and the installation of the speed-increasing box do not meet the design...
