Centralized conveying synergetic system for lubricating grease

Abstract

The invention relates to a centralized conveying synergetic system for lubricating grease, which comprises an eccentric gear, a reciprocating frame, rod pieces, an air cylinder, a lubricating grease cylinder, a cylinder piston, a lubricating grease cylinder piston, a pressure cylinder and check valves, wherein the eccentric gear is tangent with an inner surface of the reciprocating frame; one rod piece is respectively arranged on each of left and right two sides of the reciprocating frame; one rod piece is arranged at the upper end of the reciprocating frame; the rod pieces on the two sides of the reciprocating frame are respectively connected with the pistons of the air cylinder and the lubricating grease cylinder; part of the check valves are respectively arranged at an inlet and an outlet of the air cylinder; the other check valves are respectively arranged at the inlet and the outlet of the lubricating grease cylinder; and a front cavity of the pressure cylinder is communicated with a lubricating grease pipeline. The pressure cylinder is driven by the air injection of the air cylinder, so that the lubricating grease in a high-pressure cavity of the pressure cylinder is fed into the lubricating grease cylinder, and meanwhile, the piston in the lubricating grease cylinder is driven to move towards the right side, a negative pressure is generated by the lubricating grease cylinder, and the lubricating grease cylinder has a suction function to the lubricating grease, so that the sucking and pulling motions are combined, a synergetic conveying process is generated, and the lubricating grease with higher viscosity is effectively conveyed. The system has a simple structure and a good effect.

Description

technical field [0001] The invention relates to a centralized lubricating grease conveying cooperative system, in particular to a conveying system suitable for high-viscosity lubricating grease (No. 3 and No. 4 lubricating grease) in mechanical transmission. Background technique [0002] At present, the lubrication methods in mechanical transmission are mainly divided into: oil lubrication and grease lubrication. Oil lubrication is mainly used in high-speed and light-load situations, while grease lubrication is used in low-speed and heavy-load situations. The equipment of mining machinery and construction machinery is mostly large-scale heavy-duty equipment, and the lubrication method used for the rotating parts is basically grease lubrication. Lubricating grease is divided into grades: 00, 1, 2, 3, 4, etc. The higher the grade, the greater the viscosity of the grease, and the longer the lubricating effect and retention time. At present, the grease supply mainly includes: ...

AI Technical Summary

Problems solved by technology

Due to the high viscosity and low cone penetration of No. 3 and No. 4 greases, it is difficult to realize centralized grease supply. At present, there is no pumping device that can complete the transportation of this high-viscosity grease pump.
