Embodiment Construction

[0009] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0010] The centralized lubricating grease conveying cooperative system of the present invention is mainly composed of an eccentric wheel 1, a reciprocating frame 2, rods 3, 10, a cylinder 4, a grease cylinder 11, a booster cylinder 7, a rod, and a one-way valve. Wherein: the eccentric wheel 1 is tangent to the inner surface of the reciprocating frame 2, and the rotation of the eccentric wheel 1 drives the reciprocating frame 2 to reciprocate back and forth. The left and right sides of the reciprocating frame 2 are provided with a rod one 3 and a rod three 10, and the upper end of the reciprocating frame 2 is provided with a rod two 8, and the eccentric wheel 1 rotates to drive the reciprocating motion of the reciprocating frame 2. Rod one 3 is connected with the piston 4a of the cylinder 4, the rod three 10 on the left side of the reciprocating frame 2 is co...

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: ...
