In addition, a grease nipple with a protective shell is dried on the top of the rolling bearing for convenient filling of grease. Then, the slab heated to above 1300 degrees is extruded and deformed, and the thin and thick steel plates required for the middle rolling process are output.05mm-0. Because of the hazards of the special working conditions of the steel rolling office environment, not only the high working temperature, but also the cooling circulating water and the dust on the construction site erodes every component of the cardan shaft.
When the transmission system runs for a long time, the gap between the flat shaft head of the roll and the flat head of the cardan shaft sleeve will expand. The total stroke of the cross shaft instantly rubs and becomes hot, destroying the air intake system inside the rolling bearing. Therefore, at the beginning of the design scheme, it should be considered that the flat sleeve specifications of the cardan shaft are related to the flat head specifications of the rolls.
Ensure the relative stable operation of the universal joint shaft during the whole process of cold rolling, and increase the relative damage cycle time of the flat head and flat head cover. For some unique round bushings, the liner plate type is also used, so that when the radial gap expands, it can be Very convenient adjustment. Take the rough rolling link as an example, in which the cardan shaft of the roughing press is the core component used in the main transmission system of the rough rolling. For the final two cardan shafts at the precise binding position, because the speed ratio is generally above 920 rpm, it is more necessary to increase the mutual matching gap between the roll sleeve and the roll head.
Under such conditions, the radial constraint of the flat-head hole on the working roller will CV Axle manufacturers be reduced, which will cause The flat headgear causes left and right deflection with different radial forces, which endangers the reliability of all transmission systems. Everyone’s technical engineers have basically improved the structure of the original cardan shaft. The hot rolling mill consists of three parts: rough rolling, intermediate rolling and fine rolling.
