Fixed point injection positioning sprinkling type lubricating system for offset press

Abstract

Fixed-point injection and positioning spray lubrication system of offset printing machine, including transmission shaft sleeves and gears in the isolation room on both sides of the machine case, lubricating oil circuit in the isolation room, lubricating oil route in the oil storage tank at the bottom of the isolation room, and in the isolation room It is composed of the oil spray tank on the top, the oil supply main pipe and the oil pump connected between the oil storage tank and the oil spray tank, the diverter connected in series between the oil supply main pipe, and the shunt pipe connected between the output end of the diverter and one end of the moving shaft. The graded injection lubrication system is adopted to achieve the effect of distributing lubricating oil according to the required amount. A spray box is installed on the isolation room, and lubricant can be added to all moving rollers. Especially when the machine has been shut down for a long time and the moving parts are dry, it can prevent the phenomenon of jamming caused by sudden start. The invention has the beneficial effects of ensuring the harmonious and orderly operation of the moving parts during the operation of the roller shaft, ensuring stable printing quality, ensuring the normal operation of each moving part when the machine is shut down for a long time, reducing wear and prolonging the mechanical life.

Description

technical field [0001] The invention relates to a lubricating system, in particular to a lubricating system in multi-roller transmission in an offset printing press. Background technique [0002] Today's lithographic offset printing machines, whether they are web offset printing machines or sheet-fed offset printing machines, print colorful patterns and characters on white paper, and many rollers with different diameters contact each other to transmit information. As a result, in the process of transmitting information during the rotation of these rollers, the power based on them is driven by the bushes, bearings or gears at both ends of the rollers to form a harmonious rotating group. The reason why these groups of rollers can be harmonious The rotation depends on the lubricant applied between the gears, between the shaft and the bushing or bearing. With the advancement of science and technology, the electronic color separation, computer control and automation level of off...
