The bearing support of the conveyor roller includes a housing, an axis and a sliding bearing, made in one piece with the housing and placed on its inner surface. A support washer is installed on the axis working surface, and an antifriction coating is applied on the inner and end surfaces of the casing, working in direct sliding pairs with the axis working surface and with the washer supporting surface in the mode of dry (semi-dry) sliding friction and realizing the axis and with the supporting surface of the washer, the effect of selective transfer (the effect of wearlessness). In another embodiment of the bearing support of the conveyor roller, an antifriction coating is applied to the working surface of the axis, forming an inverse pair of sliding friction with the housing.

Description

The utility model relates to mechanical engineering, in particular to the bearing bearings of the rollers of the traction chains of conveyors.

Known chains containing guide rollers, made in the form of a housing and a sliding bearing, pressed into the roller. The bearing can be made of a sleeve, an insert made of bronze, cast iron, textolite or solid polymer (A. Krainev. Mechanics of machines. Fundamental Dictionary. M., Engineering, 2001, p. 819).

A known roller conveyor belt containing a bearing assembly including a housing and a sliding bearing made in one piece with the housing and placed on its inner surface, the housing is made of fiberglass, and the sliding bearing is carbon fiber, and the outer surface of the housing is the bearing surface of the roller ( application for invention No. 2004128649, publication of 2006).

The disadvantages of the known designs include the fact that the chains equipped with rollers have a relatively increased complexity, high operating costs, low maintainability and resource indicators, have low specific loads.

The objective of the proposed utility model is to expand the arsenal of technical means used in the assembly of chains of various designs, and to create a roller for traction chains with increased operational characteristics, namely: the absence of the need for lubrication, which reduces the cost of

service; increased specific loads; extended turnaround times; decrease in labor input during manufacturing.

The essence of the proposed utility model is as follows.

The bearing support of the conveyor roller includes a housing, an axis and a sliding bearing, made in one piece with the housing and placed on its inner surface. A support washer is installed on the axis working surface, and an antifriction coating is applied on the inner and end surfaces of the casing, working in direct sliding pairs with the axis working surface and with the washer supporting surface in the mode of dry (semi-dry) sliding friction and realizing the axis and with the supporting surface of the washer, the effect of selective transfer (the effect of wearlessness).

In another embodiment of the bearing support of the conveyor roller, an antifriction coating is applied to the working surface of the axis, forming an inverse pair of sliding friction with the housing.

In Fig.1-2 of the drawing presents embodiments of the proposed bearing support.

The bearing support of the conveyor roller (Fig. 1) comprises a housing 1 with a shoulder 2 directed inside the pipe 3 of the roller and located in the pipe bore, a support washer 4 mounted on the axis 5 and a wiper 6. On the inner surface of the housing 1 and the end surface of the shoulder 2 are applied layers 7 and 8 of antifriction self-lubricating material, which, interacting with the supporting surfaces of the axis and the supporting washer, form straight pairs of sliding friction.

Depending on the design, the bearing support can be disassembled (Fig. 1) and collapsible (Fig. 2), for which the housing 1 with a collar 2 directed outward from the pipe is provided with a bolt joint 9, and a layer 10 of antifriction material is applied to the opposite from the collar surface 11 of the housing 1.

An integral design is possible when a composition is used in the layers of material quality 7, 8 and 10, which implements the effect of selective transfer (wearless effect) during operation of the roller.

Using the proposed design allows to reduce the complexity in the manufacture of bearing bearings and increase its service life.
