SU1548129A1 - Idler of belt conveyer - Google Patents

Abstract

The invention relates to conveyor transport, in particular to rollers (P) of belt conveyors for transporting lumpy rock loads. The goal is to increase the reliability of operation P by reducing the dynamic loads on the stop ring (CC). For this, P includes a shell 1 fixed on a bearing cup (PS) 2 with shoulders 3 by means of the criminal code 4. Between the outer surface 5 of PS 2 and shell 1 are installed annular elastic elements 6.7 of different stiffness with the possibility of interaction with the latter. Elastic elements 6 with greater rigidity are mounted on a flange 10 located in the lower part of PS 2. When external load is acting on P, shell 1 directly compresses element 6. Since elastic elements 6.7 contact side surfaces 8, then deformation of element 6 can occur only in the direction perpendicular to the load application. The deformation of the element 7 occurs until a guaranteed clearance 9 is selected. As a result of the absence of axial forces (parallel to the axis P) on the CC 4 when the working load acts on the P, the surface wear of the PS 2 and CC 4 in the place of their contact decreases sharply. This contributes to the reliability of the work of R. 1 Il.

Description

The invention relates to conveyor transport, in particular to rollers of belt conveyors for transporting lumpy rock loads.

The aim of the invention is to increase the reliability of the roller by reducing the dynamic loads on the retaining ring.

The drawing shows a roller cut.

The belt conveyor roller contains a shell 1 fixed on the bearing cup 2 with the shoulders 3 by means of an abutment ring 4. Between the outer surface 5 of the bearing cup 2 and the shell 1 are installed elastic ring elements 6 and 7 of different stiffness, and the elastic element 6 has greater rigidity, and elastic element 7 is smaller. The elastic ring elements 6 and 7 are in contact with the side surfaces 8 between them, while the elastic elements 7 are installed with a gap 9 relative to the surface 5 with the possibility of interaction with it and are in contact with the shoulder 3 of the bearing cup 2, and the elastic elements 6 are mounted on the flange 10 located in the lower part of the bearing cup 2.

The video works as follows.

When acting on the roller external load shell 1 directly compresses the element 6 with greater rigidity. Since the elements 6 and 7 are in contact with the side surfaces 8, the deformation of the element 6 can only occur in the direction perpendicular to the application of the load. This leads, in turn, to the deformation of the element 7 with a lower stiffness in the direction parallel to the application of the load. The deformation of element 7 occurs until a guaranteed gap 9 is selected, after which both rings will work for

compression with equivalent stiffness. After the external load is removed, the shell 1 under the action of the elastic forces of the element 6 returns to its original position.

The flange 10 of the bearing cup 2 together with the elastic elements 6 and 7 form a structure with closed internal forces. The closing elastic element is the element with lower stiffness 7. Therefore, when deformed in the direction perpendicular to the load of element 6, only deformation occurs in the direction parallel to the load of element 7, and there is no pressure on the support ring 4 from the side of the bearing sleeve 2, which acts in the direction perpendicular to the application of the load (parallel to the axis of the roller) and arising from the application of the working load to the side of the roller.

As a result of the absence of axial forces (parallel to the axis of the roller) on the thrust ring 4, when the working load is applied to the roller, the wear of the surface of the bearing cup 2 of the thrust ring 4 in the place of their contact decreases, thereby increasing the reliability of the roller.
