Abstract

The invention relates to mechanical engineering and can be used in drum mills and annealing furnaces. The purpose of the invention is to increase durability by reducing sliding friction. A pin is mounted on the trunnion of at least every second roller, the outer diameter of which exceeds the diameter of the roller. This makes it possible to eliminate sliding friction between the separating elements and thereby increase the durability of the support. 6 Il.

The invention relates to mechanical engineering and can be used in drum mills and kilns.

The purpose of the invention is to increase the longevity by eliminating sliding friction.

Fig. 1 shows a general view of the rolling support; in fig. 2 shows section A-A in FIG. one; Fig, 3 - installation of bearings on the bodies ka: chen; figure 4-6 - the same options.

The support comprises a housing 1 with a working 2, a return 3 and a transition 4 sections with raceways 3 on which the rolling bodies 6 are installed in the form of rollers with pins 7.

At least, on each second pin of the roller, a remote bearing 8 is mounted. For mounting and dismounting of the rolling elements 5, an insert 9 is provided in the housing,

The support works as follows.

Kami Rollers on the rolling track of the working area 2.

Since the outer diameter of the distance bearings 8 is larger than the outer diameters of the rolling bodies 5, when they are rolling, a constant clearance is provided between the working surfaces of the rollers, which leads to their long life.

As the distance bearings 8, either standard rolling bearings or sliding bearings can be used.

Claims (1)

Invention Formula Rolling support, comprising a housing with working, retractile and transitional sections, raceways in which 20 rolling bodies are arranged in the form of rollers with trunnions installed relative to each other and placed between the last separating elements, different from the beginning of work, supports from cor-25 so that, in order to increase the dolpus 1, the insert 9 is removed and the rolling bodies 5 are inserted into the housing and the large-diameter drive shaft is installed. When the drive shaft of the body 30 of roll 5 rotates due to frictional forces between the surface of the drive shaft and roadwork by reducing friction losses, the separating elements are made in the form of bearings installed in the trunnions of at least every second roller and the outer diameters of the bearings exceed the diameter of the rollers. F Fg / g.2 five Kami Rollers on the rolling track of the working area 2. Since the outer diameter of the distance bearings 8 is larger than the outer diameters of the rolling bodies 5, when they are rolling, a constant clearance is provided between the working surfaces of the rollers, which leads to an increase in their durability. As the distance bearings 8, either standard rolling bearings or sliding bearings can be used. and 3 o b Invention Formula A rolling bearing, comprising a housing with working, retractile and transitional sections, raceways in which 0 are located rolling bodies in the form of rollers with trunnions installed relative to each other and placed between the last separating elements, distinguishing them by friction losses, separating elements made in the form of bearings mounted in the axles of at least every second roller, and the outer diameters of the bearings exceed the diameters of the rollers. fug. 3 4fig. i Compiled by I.
