Abstract
The utility model discloses a kind of belt pulley, it comprises circular wheel body, it is characterized in that: the side of described wheel body is at least provided with the annular groove that four circles cave inward, and the cross section of described annular groove is isosceles trapezoid shape, forms an annular bead between described two annular grooves.Belt pulley of the present utility model is at least provided with annular groove that four circles cave inward for installing belt in the side of wheel body, cross section is that the annular groove of isosceles trapezoid shape can firmly grasp belt, not easily landing in the process of high-speed mobile, annular bead also limit the landing of belt simultaneously; The side of wheel body central through bore is to being outside equipped with a block groove for transmission, its diameter is that 1/3rd of through-hole diameter possesses power-saving function, and the angle that the inclined-plane of two correspondences of annular groove is formed is to ensure between 33 degree to 35 degree that belt not easily departs from belt pulley when maximum driving force.It is simple that the utility model has structure, long service life, low cost and other advantages.
Description
Technical field
The utility model relates to a kind of auxiliary component, especially a kind of belt pulley.
Background technique
Belt pulley, belong to hub class part, general relative size is larger, generally to cast, to be forged to master in manufacturing process.What stock size was larger is designed to the method using casting, and material is all generally cast iron (castability is better), seldom uses cast steel (castability of steel is not good); Stock size is less, can be designed as forging, and material is steel.Belt pulley is mainly used in the occasion of Long Distant Transmit power, such as the output of miniature diesel mechanomotive force, agricultural vehicle, tractor, automobile, mining machinery, machining equipment, textile manufacturing machine, package packing machine, lathe, forging bed, the transmission of some fraction horsepower motorcycle powers, the transmission of farm machinery power, air compressor, retarder, speed reducer, generator, Gins etc.; There are some problems in existing belt pulley, as too much in raw material mostly, high cost, and it is improper etc. that precision is selected.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides that a kind of structure is simple, the belt pulley of long service life.
The technical solution of the utility model is to provide a kind of belt pulley, it comprises circular wheel body, it is characterized in that: the side of described wheel body is at least provided with the annular groove that four circles cave inward, the cross section of described annular groove is isosceles trapezoid shape, forms an annular bead between described two annular grooves.
In the utility model preferred embodiment, the center that a kind of belt pulley comprises described wheel body is further provided with a through hole, and the side of described through hole is to being outside equipped with a block groove, and the diameter of described block groove is 1/3rd of described through-hole diameter.
In the utility model preferred embodiment, the angle that the inclined-plane that a kind of belt pulley comprises two correspondences of described annular groove is further formed is between 33 degree to 35 degree.
In the utility model preferred embodiment, the angle that a kind of belt pulley comprises inclined-plane formation corresponding to described each annular groove is further equal.
In the utility model preferred embodiment, a kind of belt pulley comprises distance between described two annular groove center lines slightly larger than described annular groove center line further to the distance of bottom surface.
In the utility model preferred embodiment, two chamfered surfaces that a kind of belt pulley comprises described annular groove are further provided with some fine lines.
In the utility model preferred embodiment, a kind of belt pulley comprises annular on described wheel body further and is equidistantly provided with at least four flange holes.
Belt pulley of the present utility model is at least provided with annular groove that four circles cave inward for installing belt in the side of wheel body, cross section is that the annular groove of isosceles trapezoid shape can firmly grasp belt, not easily landing in the process of high-speed mobile, annular bead also limit the landing of belt simultaneously; The side of wheel body central through bore is to being outside equipped with a block groove for transmission, its diameter is that 1/3rd of through-hole diameter possesses power-saving function, and the angle that the inclined-plane of two correspondences of annular groove is formed is to ensure between 33 degree to 35 degree that belt not easily departs from belt pulley when maximum driving force.It is simple that the utility model has structure, long service life, low cost and other advantages.

Fig. 2 is the Facad structure schematic diagram of a kind of belt pulley of the utility model most preferred embodiment.
Embodiment
Below embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of belt pulley of the present utility model, it comprises circular wheel body 1, the side of wheel body 1 is at least provided with the annular groove 2 that four circles cave inward, the present embodiment is provided with four ring annular grooves 2, the cross section of annular groove 2 is isosceles trapezoid shape, forms an annular bead 3 between two annular grooves 2.
The center of wheel body 1 is provided with a through hole 4, and the side of through hole 4 is to being outside equipped with a block groove 5, and the diameter of block groove 5 is 1/3rd of through hole 4 diameter; The angle that the inclined-plane 6 of two correspondences of annular groove 2 is formed is between 33 degree to 35 degree; The angle that the inclined-plane 6 of each annular groove 2 correspondence is formed is equal; Distance between two annular groove 2 center lines slightly larger than annular groove 2 center line to the distance of bottom surface; Two surfaces, inclined-plane 6 of annular groove 2 are provided with some fine lines (not shown); On wheel body 1, annular is equidistantly provided with at least four flange holes 7, and the present embodiment is provided with four flange holes 7.
The annular groove 2 that belt pulley of the present utility model is arranged in the side of wheel body 1 is for installing belt, cross section is that the annular groove 2 of isosceles trapezoid shape can firmly grasp belt, not easily landing in the process of high-speed mobile, annular bead 3 also limit the landing of belt simultaneously; The side of wheel body 1 central through bore 4 is to being outside equipped with a block groove 5 for transmission, its diameter is that 1/3rd of through hole 4 diameter possesses power-saving function, and the angle that the inclined-plane 6 of two correspondences of annular groove 2 is formed is to ensure between 33 degree to 35 degree that belt not easily departs from belt pulley when maximum driving force; The angle that the inclined-plane 6 of each annular groove 2 correspondence is formed is equal, and maintain the stability of belt pulley, the surface, inclined-plane 6 of annular groove 2 is provided with some fine lines and increases friction, and protection belt can not depart from belt pulley easily further; On wheel body 1, the equidistant flange hole 7 arranged of annular alleviates the weight of belt pulley.
Above embodiment is only the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
