Abstract

The utility model relates to a roller, which comprises a bearing, wherein an outer bearing ring is wrapped by polyurethane layers or rubber layers; transverse section lines on the outer circumferences of the polyurethane layers or rubber layers are wavy lines. According to the roller, a stress area of the roller during rolling is increased, so that partial high temperature caused by relatively high elastic deformation is avoided; and due to the wavy surfaces, the friction resistance is reduced, the roller is subjected to heat radiation conveniently, and the service life of the bearing is prolonged.

Description

A kind of roller

Technical field

The utility model relates to a kind of roller.

Background technique

Present roller mainly comprises bearing, iron core or aluminium core, polyurethane layer or rubber layer, and iron core or aluminium core retainer plate are contained in outside the bearing, bearing outer ring and iron core or aluminium core transition fit, and iron core or aluminium core are enclosed with polyurethane layer or rubber layer; The body lines of the excircle of described polyurethane layer or rubber layer is a circular arc.Roller can receive toward the power of roller center extruding when rotating usually, if outer peripheral surface is an arc surface, lifting surface area is little; Promptly have only less point or the face effect of being under pressure, therefore, the local temperature of roller stress is high than other positions; Be unfavorable for heat radiation, and force bearing point or face are yielding.

The model utility content

The technical problem that the utility model will solve is: for overcome roller partial points or surface temperature higher and be unfavorable for the deficiency of dispelling the heat, the utility model provide a kind of stressed evenly and be beneficial to the roller of heat radiation.

The utility model solves the technological scheme that its technical problem adopted: a kind of roller, comprise bearing, and bearing outer ring is enclosed with polyurethane layer or rubber layer, and the body lines of the excircle of described polyurethane layer or rubber layer is a wave.

The beneficial effect of the utility model is that a kind of roller of the utility model increases the lifting surface area of roller when rolling; Avoid bigger resiliently deformable and produced localized hyperthermia, and wavy surface has been set, reduced surface friction drag; Be convenient to heat radiation, prolonged the working life of bearing.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the optimum embodiment's of a kind of roller of the utility model a structural representation.

Among the figure 1, bearing, 2, polyurethane layer or rubber layer.

Embodiment

Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1, a kind of roller comprises bearing 1, and bearing 1 outer ring is enclosed with polyurethane layer or rubber layer 2, and the body lines of the excircle of polyurethane layer or rubber layer 2 is a wave.

With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.

Claims

1. a roller comprises bearing (1), and bearing (1) outer ring is enclosed with polyurethane layer or rubber layer (2), it is characterized in that: the body lines of the excircle of described polyurethane layer or rubber layer (2) is a wave.
