Embodiment Construction

[0011] The structure of the lubricating system combined with graded injection and spraying is shown in Figure 1, which represents the pipeline structure of the forced oil inlet of each shaft sleeve in the lubricating system of the split monochrome offset printing machine. It consists of three graded splitters connected in series in the main oil supply pipe respectively. After the lubricating oil pumped in from the oil pump passes through the splitters at all levels, the pressure and flow decrease step by step. Oil lubricating the impression cylinder, rubber cylinder and printing plate cylinder with larger diameter from the pressure and flow device, and lubricating the roller shaft with smaller diameter from the oil with lower pressure and flow rate than the primary diverter from the secondary diverter , such as inking, water rollers, etc., the lubricating oil is drawn from the three-stage shunt to supply small-diameter auxiliary rollers, such as ink rollers or bridge rollers, e...

Abstract

The invention discloses an offset machine fixed point charging positioning spraying type lubrication system, which comprises transmission axle sleeves and gears arranged in the isolation chambers on the both sides of a machine case, and lubrication oil channels arranged in the isolation chambers. The lubrication oil channels comprise oil storage tanks arranged at the bottom parts of the isolation chambers, oil spraying tanks arranged at the top parts of the isolation chambers, oil supplying main pipes and oil pumps connected between the oil storage tanks and the oil spraying tanks, a diverter connected between the oil supplying main pipes in series, and branch pipes connected between the output end of the diverter and one end of the motion axle. The invention adopts a graded charging lubrication system, and realizes the effect that the lubrication oil is distributed as demand. Spraying boxes are arranged on the isolation chambers, thus all motion roll axles can be added lubricant again. The invention can prevent from the locking phenomenon caused by sudden starting when the stopping time of the machine is long particularly and the motion parts are dry. The invention has the advantages that the motion parts can keep concordantly and orderly run during the roll axle runs, the stable printing quality can be ensured, the normal working of all the parts can also be ensured when the machine stopping time is long, the wear can be reduced, and the mechanical life can be prolonged.

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 machine. 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 o...
