Plunger type grease supplementing machine

Abstract

The invention discloses a plunger type grease supplementing machine. The plunger type grease supplementing machine is mainly composed of a motor reducer, a cam, a deep groove ball bearing, a shiftingwheel, a reset spring, an ejector rod tail rod, cam shifting shafts, a sealing ring, a steel pipe tailstock, a steel pipe, an ejector rod, a shell outer cylinder, an outer cylinder straight notch, a shell inner cylinder, an inner cylinder sliding groove, an inner cylinder straight notch, a small spring, a steel ball, a piston, a piston flange and an oil outlet, the motor reducer is mounted on a rack, an output shaft of the motor reducer is fixedly connected with the cam, semicircular cam shifting shafts are symmetrically arranged at the bottom of the cam; and the deep groove ball bearing is embedded in the top of the cam and rotates along with the cam. The plunger type grease supplementing machine is relatively simple and compact in structure, the manufacturing cost is saved, and the defect that a traditional plunger type grease supplementing machine is low in efficiency in a low-temperature environment is overcome.

Description

technical field [0001] The invention belongs to the field of lubricating grease conveying equipment in a centralized lubricating system, in particular to a plunger grease replenishing machine with high grease replenishing efficiency and capable of efficiently replenishing grease in a low temperature environment. Background technique [0002] Lubricating equipment generally uses oil tanks or tanks to store grease, and refueling oil tanks or tanks is generally a manual operation, and there are almost no reliable and practical grease filling machines on the market. The front end of the plunger pump of the existing fat filling machine usually adopts two check valves (oil suction check valve and oil pressure check valve) to realize the fat filling function. In the low temperature environment, the fluidity of the grease is very poor. When absorbing oil, it has to overcome the resistance of the one-way valve to enter the plunger cavity. [0003] At present, the structure of the pl...
