Description

The invention relates to a conveyor transport, namely to the rollers of belt conveyors.

The purpose of the invention is to increase the durability of the roller by reducing the dynamic loads on its elements.

FIG. 1 shows a belt conveyor roller, general view; in fig. 2 shows the scheme of interposition of the circumference of the pipe end and the circumference of the ring grooves.

The belt conveyor roller comprises a housing 1, which consists of a pipe 2, the end parts 3 of which are turned towards its axis towards the glass 4. On the outer surface of the glasses there are annular recesses 5 having walls 6 and 7 and a bottom 8, as well as the end of pipe 9.

In the proposed roller, the individual parts — a pipe and two bearing glasses — are combined into a non-separable assembly, which is part of a roller, like a roller body, bearing glasses in which are fastened coaxially by a simple operation — assembly by stamping without heating. The end portions of the pipe are seated in an annular groove of a completely defined width, structurally determined depending on the thickness of the pipe wall by the press fit, but the press fit is not the end of the pipe, but the side surfaces of the pipe.

 ) The connection of the pipe with the cups provides the load distribution along the glass along the axis of the roller through the contact zones of the press fit of the pipe wall and the sides of the annular groove of the bearing glass.

In addition, under normal conditions, the pipe end does not come into tense contact with the bottom of the annular recess. At excessive loads on the roller, the end of this opportunity, but overcoming the npeccoayto fit, to some extent approach at some point the circumference of this part of the annular recess of the bearing cup (the diagram of relative position of the circumference of the pipe end and the circumference of the annular 0 groove, 2) the strength of the roller body is not impaired, since the pipe with the glass is still connected along the press section, the alignment of the glasses, and therefore the bearings, is also not disturbed.

Occurred shear of the pipe wall in the cavity of the recess on. The glass consumes (absorbs) the energy received by the roller from the excessive load (push), often from large fractions of the rock mass on the belt of the working conveyor.

This means that the selected connection in this case works as a damper, extending the life of the bearings.

The means of making a strong connection between the tube and the bearing cups in the non-separable roller body is a press fit of the pipe wall in the annular recess of the glass, in which tension is carried out only along the side surfaces of the pipe wall, while the ends do not come into tight contact with the bottom of the annular groove of the glass, as a result of which the roller body acquires a damping effect that prevents its construction from approaching it to a completely rigid system.

Claims (1)

A ROLL OF A TAPE CONVEYOR, comprising a housing with end parts bent to the axis, located between the walls of the annular recesses on the outer surface of the bearing cups mounted on the axis of the bearing, and a seal, characterized in that what. In order to increase the durability of the roller by reducing the dynamic loads on its elements, the walls of the recesses are made parallel to the end sections, which are connected to them with an interference fit and the possibility of forming a gap with a high bottom.
