Abstract
The utility model provides a belt pulley which is hard to fall off and deflect a belt, low in manufacture cost, simple in structure, convenient to manufacture, and high in transmission efficiency. The belt pulley comprises at least three of coaxial discs which are arranged along with the axial direction of the belt pulley, wherein a plurality of arc grooves with the same quantity are disposed along with the peripheral direction of each disc, and the length of the arc of each arc groove is larger than that of each semiarc; the diameter of each disc is gradually enlarged from the two sides of the belt pulley to the middle of the belt pulley along with the axial direction of the belt pulley; a plurality of round bars are disposed in the arc groove of each disc along with the peripheral direction of the belt pulley, and each round bar is penetrated through the arc groove of each disc; and the diameter of each round bar is the same as that of each arc groove.
Description
Technical field
The utility model relates to a kind of belt pulley.
Background technique
Existing belt pulley mainly comprises a wheel hub, middle high, a low smooth cambered surface in both sides of the side face of wheel hub.Like this, belt drives belt and moves around after on the wheel hub under the drive of rotating pulley.
Because the cambered surface of wheel hub is difficult to processing, so this belt pulley manufacturing sealing, cost is very high.In addition, less between the smooth cambered surface with the frictional force of belt, cause belt easily and belt pulley skid, transmission efficiency is low, and belt comes off from belt pulley easily.
Summary of the invention
The purpose of this utility model provides a kind of belt difficult drop-off, is difficult for sideslip, simple in structure, easily manufactured, cost is low, transmission efficiency is high belt pulley.
This belt pulley comprises along three of the belt pulley axially-aligned coaxial disks at least, each disk circumferentially have an identical arc groove of a plurality of quantity, the arc length of arc groove is greater than semi-circle; Along the axial direction of belt pulley, to the centre of belt pulley, the diameter of each disk increases gradually from the both sides of belt pulley; Many poles are in the arc groove that circumferentially is arranged on each disk of belt pulley, and each root pole passes the arc groove of each disk; The diameter of pole is identical with the diameter of arc groove.
The beneficial effects of the utility model: since from the both sides of belt pulley to the centre of belt pulley, the diameter of each disk increases gradually; And each root pole passes the arc groove of each disk, like this each root pole promptly be bent to both sides low in the middle of high arc.So belt is on this belt pulley the time, belt is to contact with the surface of pole, and each pole circumferentially is spaced, so contacting of the side face smooth with respect to belt and existing belt pulley, the frictional force of this belt pulley and belt is bigger, is difficult for skidding the transmission efficiency height between belt and each pole, belt also is difficult to come off from belt pulley, is difficult for sideslip.In addition, of the present utility modelly manufacture fairly simplely, only need insert pole the arc groove of each disk, pole is the natural torsion camber.And do not need it is carried out gold machining as existing belt pulley.And the utility model is made up of the polylith disk, with respect to existing belt pulley, has saved material, has alleviated weight, can effectively reduce to drive the power of motor that belt pulley rotates.
Above-mentioned belt pulley, arc groove are distributed on the circumferential of disk.
Above-mentioned belt pulley, described disk is made up of left semicircle dish that removably connects and right semi-circle dish.With making and the installation that makes things convenient for disk.And because disk need be fixedly linked with Pulley shaft, rotating under the drive of Pulley shaft, for convenience being connected of disk and Pulley shaft, the center of disk has the center hole that is used to pass Pulley shaft; Circumferentially having of Pulley shaft drives the stepped part that belt pulley rotates; Center hole is made up of the right side half center hole of half center hole of the left side on the left semicircle dish and right semi-circle dish; In a left side half center hole and right half center hole one is the corresponding step hole with the stepped part of Pulley shaft.
Above-mentioned belt pulley, disk are three.

Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Belt pulley as shown in Figure 1, it comprises along Pulley shaft 10 to three coaxial disks 1,2,3 of arranging, each disk circumferentially have a plurality of quantity circumferential arc groove 4 identical, that be distributed on disk, the arc length of arc groove is greater than semi-circle.Two disks, 1,3 sizes of both sides are identical, and middle disk 2 diameters are greater than the disk 1 of both sides.Many poles 5 are in the arc groove that circumferentially is arranged on each disk 4 of belt pulley, and each root pole passes the arc groove of each disk; The diameter of pole 5 is identical with the diameter of arc groove 4.
Referring to Fig. 2,3, described disk is made up of left semicircle dish 6 that removably connects and right semi-circle dish 7.Respectively be provided with corresponding embedding part 8 on the phase-contact surface of left semicircle dish 6 and right semi-circle dish 7.For example, if the recessed draw-in groove 81 of the embedding part of left semicircle dish 6, then the embedding part of the correspondence on the right semi-circle dish 7 is and draw-in groove 81 corresponding juts 82.The center of disk has the center hole 9 that is used to pass Pulley shaft; Center hole is made up of the right side half center hole 92 of half center hole 91 of the left side on the left semicircle dish and right semi-circle dish; Circumferentially having of Pulley shaft 10 drives the stepped part 11 that belt pulley rotates.Right half center hole 92 is the corresponding step holes with the stepped part 11 of Pulley shaft.
