Abstract

The invention discloses a thin oil lubricating device for a coal mine conveyor sprocket, and belongs to an underground coal mine machine. The thin oil lubricating device solves the problem that the bearings and the oil seal of the handpiece driving sprocket of a scraper are burned out easily. The thin oil lubricating device comprises a sprocket body (10), a left bearing (11), a right bearing (12), a sprocket central shaft (13) and a lubricating oil way (14) of the bearings, wherein a lubricating oil storage area (1) is arranged on the outside part at the left end of the sprocket central shaft(13) in the sprocket body (10); a plane cam with a convex lower edge is arranged in the outside part at the left end of the sprocket central shaft (13) in the sprocket body (10); an oil pump (3) is fixedly arranged on the outer side at the left end of the sprocket central shaft (13); the left end of the pump body of the oil pump (3) is connected with a cam-shaped rocker arm through a hinge; the right convex part of the cam-shaped rocker arm is arranged on the outer side of an oil pump plunger of the oil pump (3); and the inner side of the oil pump plunger of the oil pump (3) is connected witha plunger spring. The thin oil lubricating device is particularly applied to underground production.

Description

technical field [0001] The invention relates to a coal mine underground machine, in particular to a thin oil lubricating device for a head drive sprocket of a scraper conveyor on a coal mine underground working face. Background technique [0002] At present, the thin oil lubrication system of the head drive sprocket of the scraper conveyor in the underground working face usually adopts the oil pipeline lubrication method of the high oil tank. This lubrication method relies on the lubricating oil in the oil tank at the high The oil is injected into the head drive sprocket of the scraper conveyor, but in the actual working environment, the lubricating oil delivery system often has air resistance, so that the lubricating oil cannot be injected into the head drive sprocket in time. In addition, due to coal mine work The increase of the inclination angle of the face mining will also prevent the lubricating oil from being injected into the bearings and oil seals on both sides of t...
