A kind of device and its working method for bearing lubricating grease

Abstract

The invention provides a device and working method for bearing grease filling, comprising: a sealing cylinder, an intermediate passage is provided on the sealing cylinder, the intermediate passage penetrates to the upper end and the lower end of the sealing cylinder, and the upper part of the sealing cylinder is provided with There is a grease supply port; the cylinder is set above the sealing cylinder, and the lower end of the piston rod of the cylinder is provided with a push plate, which is set in the middle channel; the piston rod is provided with a groove, when the push plate is in the seal At the top of the sealing cylinder, the groove is above the sealing cylinder; the grease supply pump is connected to the grease supply port of the sealing cylinder; the positioning plate is placed on the top surface of the sealing cylinder, and the positioning plate is provided with bayonets. It can be snapped into the groove; the guide column is arranged vertically, and the guide column is used for the bearing sleeve. The operation process of the invention is simple, the bearing is convenient to install and disassemble, greatly reduces the labor intensity of operators, saves the amount of lubricating grease used, is not easy to pollute the environment, and improves the assembly quality of the bearing.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment maintenance, in particular to a device for adding grease to bearings and a working method thereof. Background technique [0002] Squeeze rolls are important equipment used in steel cold rolling production and require regular off-line maintenance. The maintenance process includes dismantling the self-aligning roller bearings at both ends of the squeeze roller, and after cleaning and inspection, pre-grease the bearings to ensure smooth operation of the bearings. [0003] The maintenance frequency of the squeeze roller is relatively high, the amount of monthly maintenance is large, and the construction period is short. At present, the process of pre-applying grease to the bearing is mainly completed by manual operation, and there is a problem that the internal grease of the bearing is not applied properly. In general, there is the problem of grease contamination on the outside of the be...

Problems solved by technology

[0003] The maintenance frequency of the squeeze roller is relatively high, the amount of monthly maintenance is large, and the construction period is short. At present, the process of pre-applying grease to the bearing is mainly completed by manual operation, and there is a problem that the internal grease of the bearing is not applied properly. Even, the problem of grease contamination on the outside of the bearing, and the operation is time-consuming and laborious, and the efficiency is low
