The rolling bearing of hollow shaft equipment has a special meaning. The hollow shaft has a certain meaning in the industry; the first is the rolling bearing used in the fine grinding of industrial mills; it has been widely promoted in China; It saves electricity consumption; improves production value; saves smooth oil; reduces repairs; reduces pollution and other aspects; receives outstanding results; It is a method of tumbling; there are many unreasonable points about the equipment mode of the hollow shaft and the tumbling shaft; the manufacturer who applies the mill brings certain disadvantages in the operation of the future work; therefore, in this respect The meaning has a better effect; we have specially proposed the most aunty effect of the rolling of the hollow shaft equipment of the mill.
The old method of grinding hollow shaft equipment rolling bearing is to process the hollow shaft into the inner diameter of the suitable bearing; the bearing thermal equipment, the bearing part, the outer part of the bearing inner ring has a top sleeve; the top sleeve is pressed into the discharge spiral cylinder (or the feeding and discharging material) The bushing is fixed on the hollow shaft by bolts; the compacting is carried out. During the grinding operation; the feeding screw and the fixing bolt are often loose; the top sleeve and the hollow shaft are displaced; the dust will be from the hollow shaft and the top sleeve. The gap between the two enters the bearing box; makes the smooth grease dirty; causes smoothness; the formation of the damaged appearance of the bearing occurs.
In order to overcome some of the above defects; after several years of theory and exploration; portrayed a new type of equipment approach; and in some applications manufacturers have been outstanding applications.
The method is: the diameter of the hollow shaft device of the mill is thickened; the thin oil cooled by the hollow shaft transfers the temperature of the hollow shaft to the bearing to a normal range below 60 degrees.
The industrial aspect has chosen a certain role for the bearing mill; therefore, the time of use must pay attention to the expression of a meaning in the central control; this is a comparative effect through various aspects.
