Strip mill universal shaft is divided into roughing mill and finishing mill; rolling cardan shaft as the rolling force and huge torque is not stable, so the cardan shaft fork head to select more than 42CrMo material as the foundation, through the heat treatment process to adjust the metallographic structure, the universal shaft speed in this area is relatively low, usually a week to fill a bearing sleeve grease can, then check if the gap is larger than 5mm the wear to the timely replacement of lining sleeve lining board. However, the selected parts of cardan shaft of the mill is a luxurious, 3 front cardan shaft rolling can be selected balance level is relatively low, or you can choose to repair the cardan shaft, the general life of more than 6 months, but the last two universal shaft parts finishing need high-speed balance (the experience we know a new universal shaft, the service life can reach more than 10 months, only the general maintenance after the cardan shaft reached about 2 months, so that new, consumption will be relatively small); Sitong  - million - over to the middle of the hot rolling mill used in the manufacture of universal shaft in need than the ordinary use of cardan shaft increase the thickness of 5-10mm, in order to ensure the position of the bracket wear. This general use units are not aware of.
