A Scissor Grab Self-lubricating Pulley Mechanism

Abstract

The invention discloses a self-lubricating pulley mechanism of a scissor grab bucket, which comprises a convex groove, a pulley block 1, a connection groove 1, a connection sleeve, an oil filling port assembly, a pulley block 2, a connection groove 2, a gasket, a lock nut, an external thread and Oil storage tank; the present invention has a reasonable and simple structure, and the sealing cover provided here can avoid the phenomenon of oil leakage of the added lubricating oil, which improves the long-term lubrication effect of the mechanism; the spiral groove provided in the present invention, When the pulley rotates, the lubricating oil in the oil storage tank can be automatically transported to the lubricating tank through the connecting groove one to lubricate the bearing, thereby avoiding the damage of the bearing caused by the failure of lubrication and affecting the smooth progress of production; It can avoid the clogging of the oil passage, which improves the production efficiency and the service life of the scissor grab pulley mechanism; the multiple sealing rings provided in the tool of the present invention can greatly improve the sealing performance and lubrication of the pulley mechanism when it is working. performance.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a self-lubricating pulley mechanism for a scissor grab bucket. Background technique [0002] As a tool for grabbing various bulk and bulk materials, the grab is widely used in metallurgy, mining, coal and transportation. Working in the environment of steam, water and mud mortar, the dynamic point seal of the pulley mechanism is poor. , Lubrication failure causes bearing damage, maintenance labor intensity is high, spare parts consumption is large, production cost increases, and the performance of the pulley mechanism is poor, which affects the smooth progress of production. Contents of the invention [0003] The object of the present invention is to provide a scissor grab self-lubricating pulley mechanism in order to solve the above problems, which solves the problem that the existing scissor grab pulley mechanism has poor lubrication effect, which seriously affe...
