During the use of printing equipment, parts often wear out, and the wear and tear of parts is mainly affected by external factors, because the internal factors are fixed during the manufacturing process of the printing equipment, so the operation For those who maintain printing equipment, it is necessary to reduce the wear and tear of parts by controlling external factors, prolong the use time of the equipment and keep the equipment running stably. Then we first need to understand what are the several external causes. 1, friction medium We can generally use lubricating oil to form an oil film in the friction medium. This way, the direct dry friction of the contact surface can be reduced, and the frictional resistance is lowered by the oily liquid to reduce the wear. Different experiments have shown that the reasonable matching clearance is 4 times of the thickness of the oil film. When the gap is large, the oil will become larger. When the oil film is thick, it is more favorable for lubrication. Therefore, we should pay attention to the shaft in our actual production. Maintenance and maintenance of sets, sets, etc., if it is found that the gap is too large, poor lubrication, it is necessary to replace and repair. 2, the form of friction When the frictional resistance is small and the contact pressure is high, the heat dissipation capability is strong, and the wear is relatively slow. The frictional resistance between the contact surfaces such as the rolling bearing, the gear tooth surface and the machine member that are in contact with the rolling form is relatively small, and is in a sliding form. The friction surface of the contact will wear faster. 3, the speed of movement The faster the movement speed in the machine, the higher the temperature of the surface will be. When the temperature reaches 150 degrees, the effect of the lubricating oil will be reduced, and the oil film will be damaged, which will increase the wear and cause equipment failure.
