ANTIFRICTION SUPPORT

摘要

The solution applies to the field of textile machinery and deals with a roller bearing designated to the bearing of the spinning rotor of the textile machine with rotations exceeding 6 x 10<4> min<-1>. The roller bearing consists of the outer ring of the bearing, in which two grooves for the sealing medium are created and at least one greasing hole is made that empties with one end to the inner space of the bearing and contains grease. A member from a porous material is placed within the greasing hole. A lining is pressed on the outer ring of the bearing that embraces the outer ring of the bearing at its full length. The lining is provided with a radial hole with a plug. The merit of the solution is the fact that a cavity for the greasing regulation medium is made in the outer ring of the bearing, which the greasing hole empties to by means of the other end. The cavity for the greasing regulation medium can be created in the lining, or, respectively, in the lining and the outer ring of the bearing.
