In the process of normal operation of the cam in the printing machine, each cycle will collide with adjacent components. This load effect occurs on the cam and has a great influence on the cam. The load forces occurring on the cams at different times come from different directions, and their action points and sizes are constantly changing. The load on the cam structure in a printing machine can be seen as a variable static load. If the direction of the load is opposite to the direction of the lift of the follower, then the speed is increased, and the load is in the same direction as the inertial force; if it is in the deceleration section, the load is reversed from the inertial force. In printing machinery, the touch of cams and rollers can be attributed to a typical Hertzian touch. In order to simplify the analysis, if the load on the cam structure is the maximum instantaneous load in a cycle during the calculation, it can be considered that the cam pair fails when the risk part fails. In the process of creating a conflict, the touch of the conflicting interface is first of all a micro-convex touch that accounts for a few percent of the total appearance of the printing machine. When the touch point is subjected to repeated rubbing pressure, the surface molecular structure is changed and the adhesion effect occurs, and the substance is transported from the side of the conflict side to the other side of the conflict pair. In order to alleviate the conflicts and abrasions generated during the working process of the printing machinery, in order to avoid damage to the printing machinery, a small amount of extreme pressure anti-wear agent may be added to the lubricating oil as appropriate. This additive can withstand conflicting loads, reduce sliding resistance and avoid scratches during conflicts. In the process of processing and repairing the failure of the printing machinery cam, it is possible to continuously sum up the experience and lessons, and make theoretical preparations for the handling of defects in the printing machinery work in the future, so as to prevent the problem beforehand. When there is a problem in the printing machinery, the diagnosis and treatment can be carried out in time, so that the printing machinery can be repaired in time to minimize economic losses.
