A self-lubricating cable guide wheel

Abstract

The invention relates to a self-lubricating wirerope guide wheel which comprises a rolling outer frame and a rotary shaft installation hole, wherein the rolling outer frame is used for dragging a wirerope and the rotary shaft installation hole is formed in the middle of the guide wheel. The guide wheel further comprises an oil storage cavity and oil leakage grooves, the oil storage cavity is arranged between the rolling outer frame and the rotary shaft installation hole, the oil leakage grooves are formed in the rolling outer frame and used for communicating the oil storage tank and a groove-shaped seam in the outer wall of the rolling outer frame, the number of the oil leakage grooves is at least two, and the oil leakage grooves are distributed in an annular array relative to the center of the guide wheel. By means of centrifugal force during rotation of the guide wheel and siphon force of the oil leakage grooves, lubricating oil can leak to the wirerope through the oil leakage grooves, the effect of preventing the wirerope from rusting is achieved, certain lubrication is provided, and good economic benefits and social benefits are achieved.

Description

Technical field [0001] The invention relates to a self-lubricating steel cable guide wheel, which belongs to the field of hardware accessories. Background technique [0002] In the hoisting machinery, the transmission mechanism of the guide wheel and the steel cable is very common, but the life of this structure is often determined by the steel cable. Especially in the elevator, the steel cable will inevitably be oxidized and worn due to its own material. , It needs to be replaced after a long time of use, otherwise it will bring safety hazards, and the replacement of the steel wire generally requires shutdown, and the replacement of the equipment can be performed after the entire device is removed, which is very inconvenient. Summary of the invention [0003] The purpose of the present invention is to provide a guide wheel that can extend the service life of the steel cable and improve the safety factor of the equipment. [0004] The present invention is realized in the following ...
