Abstract

This utility model provides a kind of belt sheave, it includes wheel body, bearing, rubber blanket, rivet, dust excluding plate, wherein, wheel body is annular, is fixed with bearing in its internal ring, and wheel body side sidewall is provided with groove, rubber blanket it is provided with in groove, groove surfaces is covered by dust excluding plate, and rivet enters outside dust excluding plate, passes fixing from wheel body opposite side after rubber blanket；Being toothed around on the wheel face of wheel body, the wheel face edge of wheel body is provided with position-limited edge, and the height of position-limited edge is higher than the gear teeth.This programme has simple in construction, easy to make, using effect good, wear rate is little, the advantage of length in service life.

Description

A kind of belt sheave

Technical field

This utility model relates to belt pulley technical field, refers in particular to a kind of belt sheave.

Background technology

Belt pulley belongs to hub class part, and general relative size is bigger, typically to cast, to be forged in manufacturing process Main.What stock size was bigger is designed as the method with casting, and material is typically all cast iron (casting character is preferable), seldom uses cast steel (casting character of steel is the best)；Stock size is less, can be designed as forging, and material is steel.Belt pulley is mainly used in long distance From the occasion of transmission power, the such as output of miniature diesel mechanomotive force, agricultural vehicle, tractor, automobile, mining machinery, machinery adds Construction equipment, textile machine, package packing machine, lathe, forging bed, the transmission of some fraction horsepower motorcycle powers, agricultural machinery power Transmit, air compressor machine, decelerator, reductor, electromotor, cotton gin etc..The wheel tooth height of existing pulley surface is all one Sample, it sometimes appear that sideslip, and when using integrally casting, internal ring abrasion is relatively big, affects its service life.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, using effect are good, mill Loss rate is little, the belt sheave of length in service life.

For achieving the above object, technical scheme provided by the utility model is: a kind of belt sheave, it includes wheel Body, bearing, rubber blanket, rivet, dust excluding plate, wherein, wheel body is annular, is fixed with bearing, on the sidewall of wheel body side in its internal ring Being provided with groove, be provided with rubber blanket in groove, groove surfaces is covered by dust excluding plate, and rivet enters outside dust excluding plate, through rubber Pass fixing from wheel body opposite side after rubber cushion；Being toothed around on the wheel face of wheel body, the wheel face edge of wheel body is provided with position-limited edge, The height of position-limited edge is higher than the gear teeth.

Described bearing is riveted in wheel body internal ring, and the riveting point of every side is eight, is evenly distributed on bearing both sides.

The described angle between adjacent teeth is 40～45 °.

This utility model is after using such scheme, and belt pulley is in addition to dead eye, and black zinc electroplated by rivet, and rubber blanket color is Black, dust excluding plate electrophoretic paint black, this programme uses 8 riveting bearings, and position is any, uses multiple spot riveting, can increase Adding bond strength, thus increase the service life, after riveting, hand-held pulley rotation is flexibly without abnormal sound, without clamping stagnation and abnormal sound, Use make after bearing with other parts with the use of time, operate more smoothly；This programme have simple in construction, easy to make, Using effect is good, wear rate is little, the advantage of length in service life.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

Fig. 2 is the sectional view of this utility model Fig. 1.

Detailed description of the invention

Below in conjunction with all accompanying drawings, the utility model is described in further detail, and preferred embodiment of the present utility model is: ginseng Seeing accompanying drawing 1 and accompanying drawing 2, a kind of belt sheave described in the present embodiment includes wheel body 1, bearing 2, rubber blanket 3, rivet 4, prevents Dirt plate 5, wherein, wheel body 1 is annular, is fixed with bearing 2 in its internal ring, and described bearing 2 is riveted in wheel body 1 internal ring, each The riveting point of side is eight, is evenly distributed on bearing 2 both sides；Wheel body 1 side sidewall is provided with groove 6, is provided with rubber in groove 6 Pad 3, groove 6 surface is covered by dust excluding plate 5, and rivet 4 enters outside dust excluding plate 5, after rubber blanket 3 from wheel body 1 another Side passes fixing；Being toothed around on the wheel face of wheel body 1, the wheel face edge of wheel body 1 is provided with position-limited edge 7, the height of position-limited edge 7 Higher than the gear teeth, the described angle between adjacent teeth is 40～45 °.The present embodiment is at belt pulley in addition to dead eye, and rivet is electric Black coating zinc, rubber blanket color is black, dust excluding plate electrophoretic paint black, and this programme uses 8 riveting bearings, and position is any, uses Multiple spot rivets, and can be greatly increased bond strength, thus increase the service life, and after riveting, hand-held pulley rotation is as good as flexibly Sound, without clamping stagnation and abnormal sound, make after using bearing with other parts with the use of time, operate more smoothly.

The embodiment of the above is only the preferred embodiment of this utility model, not limits reality of the present utility model with this Executing scope, therefore the change that all shapes according to this utility model, principle are made, all should contain at protection domain of the present utility model In.
