Abstract
The utility model discloses a combined synchronous belt wheel which comprises a wheel body and a shaft sleeve, wherein the wheel body is sleeved on the outer ring of the shaft sleeve. Taper holes are drilled along the radial direction of the bottom land portions of the wheel and the shaft in a matched mode, wherein internal thread taper pins are arranged inside the taper holes, the shaft sleeve is a step shaft sleeve, and one end surface of the wheel body is attached to the inner end surface of a bigger end of the shaft sleeve. When the wheel is overloaded, the internal thread taper pins are cut off, and therefore overload protection functions are achieved. Because the internal thread taper pins are arranged on the bottom land portions of the wheel and is free of occupied areas, the wheel body needs not moving along a radial direction when the wheel is assembled and disassembled, and particularly, the wheel is suitable for occasions with limited space. The internal thread taper pins are provided with threaded holes which can be conveniently disassembled through a tool, wherein the end portion of the tool is a screw. The internal thread taper pins meet national standard requirements, and can be easily replaced. Because plugs are arranged on the internal thread taper pins, cut-off internal thread taper pins are prevented from flying out, and therefore accidents can be avoided. The combined synchronous belt wheel effectively solves overload protection problems of transmission of a synchronous belt, and has the advantages of being simple in structure, high in reliability, convenient to assemble and disassemble and the like.
Description
Technical field
The utility model relates to a kind of combination synchronous pulley, belongs to the mechanical transmissioning technology field.
Background technique
The engagement driving that toothed belt transmission is comprised of Timing Belt and synchronous pulley, its motion and power are by being with the tooth transmission that is meshed with the gear teeth.Compare with the normal tape transmission, the advantage such as toothed belt transmission has between band and belt wheel without relative sliding, velocity ratio is constant, transmission efficiency is high, compact structure, wear resistance are good, shortcoming are non-slip when transshipping, and can cause the damage of motor or important parts.
The model utility content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of combination synchronous pulley is provided, and can protect motor or important parts not damaged when overload.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of combination synchronous pulley comprises wheel body and axle sleeve, and described wheel body is sleeved on the axle sleeve outer ring, described wheel body tooth bottom and axle sleeve are radially joined the burr-drill hole, described taper hole is equipped with taper pin with internal thread, and described axle sleeve is the ladder axle sleeve, and described wheel body one end face and axle sleeve major part interior edge face are fitted.
Further, described taper hole tapering is 1: 50.
Further, the taper pin with internal thread number of described setting is 1-4.
Further, described taper pin with internal thread major part also is provided with screw plug in the same way.
The beneficial effects of the utility model: because wheel body is connected taper pin with internal thread with axle sleeve and connects, taper pin with internal thread is cut off during overload, realizes overload protection function; Taper pin with internal thread is arranged at gear teeth bottom, does not take up room, and mounting or dismounting needn't move axially wheel body, are particularly suitable for the occasion that the space is restricted; Taper pin with internal thread is provided with tapped hole, and being convenient to the end is that the instrument of screw rod removes it; Taper pin with internal thread complies with the national standard requirements, and interchangeability is good; Be provided with again screw plug, make that the taper pin with internal thread of cutting off is unlikely to fly out, avoid accident to occur; Hence one can see that, and the utility model efficiently solves the overload protection problem of toothed belt transmission, have simple in structure, reliability is high, be convenient to the advantages such as installing/dismounting.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of plan view that makes up synchronous pulley of the utility model;
Fig. 2 is a kind of left view that makes up synchronous pulley of the utility model.
Embodiment
Toothed belt transmission is comprised of driving pulley, Timing Belt and driven pulley, and its motion and power are by the transmission that is meshed of driving pulley, Timing Belt and driven pulley.A kind of combination synchronous pulley described in the utility model is driven pulley.
As shown in Figure 1 and Figure 2, a kind of combination synchronous pulley, comprise wheel body 2 and axle sleeve 3, described wheel body 2 is sleeved on axle sleeve 3 outer rings, described wheel body 2 teeth bottom and axle sleeve 3 are radially joined the burr-drill hole, and described taper hole is equipped with taper pin with internal thread 4, in order to make wheel body 2 and axle sleeve 3 axially locating, described axle sleeve 3 is the ladder axle sleeve, and described wheel body 2 one end faces and axle sleeve 3 major part interior edge faces are fitted.Taper pin with internal thread 4 is made by NBS, and described taper hole tapering is 1: 50.According to diameter and the number of shear strength calculating taper pin with internal thread 4, general taper pin with internal thread 4 numbers are 1-4.Hurt sb.'s feelings for the taper pin with internal thread 4 that prevents from cutting off flies out, described taper pin with internal thread major part also is provided with screw plug 1 in the same way.After taper pin with internal thread 4 was cut off, available end was that the instrument of screw rod removes it.
Obviously, the above is the basic elaboration of making up synchronous pulley to a kind of.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the invention.
