Bearing tooth surface lubricating device for wind generating set

Abstract

The invention relates to a bearing tooth surface lubricating device for a wind generating set. The bearing tooth surface lubricating device for the wind generating set is used for lubricating the engaged position of a variable paddle and a yaw gear ring, installed on a driving gear and rotates along with the driving gear. An oil distributing disk is connected to a fixed support through a shaft, the shaft is fixedly connected with the fixed support through a flat key, and a spring is installed between the boss end face of the shaft and the fixed support. The oil distributing disk can rotate around the shaft and a bronze bushing. Oil smearing sticks are evenly distributed on the lower end face of the oil distributing disk, the oil smearing sticks are fixedly connected with the oil distributing disk in a sealed mode, and the quantity of the oil smearing sticks is equal to the tooth quantity of the driving gear. The oil smearing sticks are placed at the tooth roots of the driving gear, and the lower end face of the oil distributing disk is connected with the upper end face of the driving gear in a pressed and contacting mode. A set of oil outflow holes are formed in the side of each oil smearing stick located at the engaged position of the driving gear and a bearing gear, the set of oil outflow holes are enlarged in sequence from up to down, and the oil outflow holes release oil only from the direction of the engaged position of the driving gear and the bearing gear. The set of oil outflow holes are connected with a fixed-point centralized lubrication system of the tooth surface of the variable paddle through a connecting joint.

Description

technical field [0001] The invention relates to a pitch and yaw bearing open gear lubricating device for a wind power generator set, in particular to a bearing tooth surface lubricating device for a wind power generator set. Background technique [0002] At present, there are usually two ways for wind turbines to lubricate pitch or yaw bearing tooth surfaces: 1. Manually apply lubricant regularly; 2. Adopt automatic lubrication, and install lubricating small teeth or jet lubrication devices for oiling. Grease pinions mesh with drive teeth or lubricate pinions mesh with bearing teeth. The first method has disadvantages: Due to the relatively large environmental and human factors, it cannot guarantee that the bearing tooth surface can be properly lubricated. The second method, such as Chinese Patent Publication No. CN103388673A, discloses a fixed-point injection lubrication method for pitch-variable open gears of wind turbines. At the position where the pitch pinion meshes w...
