Abstract
The invention discloses a belt pulley assembly, which comprises a belt pulley and a belt pulley shaft. The belt pulley comprises a bearing hole; the belt pulley shaft and the belt pulley are formed separately; and the bearing hole comprises a guiding part which is used for guiding the belt pulley shaft to penetrate through the bearing hole. Because the belt pulley shaft is separated from the belt pulley, the belt pulley shaft can be replaced conveniently. Besides, the belt pulley is provided with the guiding part which guides the belt pulley shaft, so that the belt pulley shaft is replaced smoothly.
Description
Technical field
The invention belongs to field of mechanical technique, be specifically related to a kind of belt pulley assembly.
Background technique
In existing belt pulley assembly, generally include belt pulley and with the integrated belt pulley axle of belt pulley, external machinery is through driving the running of this belt pulley axle and then drive belt dish.But in some cases, the belt pulley axle can inevitably wear and tear, and then causes needs to change whole belt pulley assembly, so, can increase the weight of cost of production.
Summary of the invention
The object of the present invention is to provide the belt pulley assembly that to change the belt pulley axle.
Be realization foregoing invention purpose, a kind of belt pulley assembly provided by the invention, this belt pulley assembly comprises:
Belt pulley comprises bearing hole on it;
The belt pulley axle, said belt pulley axle and belt pulley split form;
Wherein, comprise guide portion on the said bearing hole, be used to guide said belt pulley axle and pass.
As further improvement of the present invention, the outer edge side of said belt pulley includes the belt gear teeth.
As further improvement of the present invention, the quantity of the said belt gear teeth is set to 5.
As further improvement of the present invention, define the groove that inverted trapezoidal shape is arranged between the said adjacent belt gear teeth.
As further improvement of the present invention, the said belt gear teeth have the cross-section area that successively decreases from the direction away from said bearing hole.
As further improvement of the present invention, the diameter of said bearing hole is 60 millimeters.
As further improvement of the present invention, said guide portion has the diameter that increases progressively from the direction away from said bearing hole.
Compared with prior art, the present invention can conveniently carry out the replacing of belt pulley axle through being arranged at the belt pulley axle that belt pulley separates, and, the guide portion of guiding the belt pulley axle is set on the belt pulley, make that the process of changing the belt pulley axle is more smooth.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of belt pulley in the belt pulley assembly of the present invention.
Embodiment
Below will combine embodiment shown in the drawings to describe the present invention.But these mode of executions do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these mode of executions, method or the function all is included in protection scope of the present invention.
Join Fig. 1, introduce an embodiment of belt pulley assembly of the present invention.In the present invention, because the belt pulley axle does not relate to the improvement on the concrete structure, so accompanying drawing omits.In this mode of execution, these belt pulley 10 assemblies comprise belt pulley 10 and the belt pulley axle that cooperates with belt pulley 10.
Include bearing hole 11 on the belt pulley 10, in this mode of execution, this bearing hole 11 is positioned at the center of belt pulley 10 in fact.
Belt pulley axle and belt pulley 10 splits form, and this belt pulley axle can match with bearing hole 11, to reach the purpose that belt pulley 10 and belt pulley axle freely split.Through setting like this, the belt pulley axle can carry out freely replacing, and needn't change whole belt pulley 10 assemblies when wearing and tearing take place or damage, and so can reduce production costs.
As preferred embodiment, comprise guide portion 12 on the bearing hole 11, be used to guide the belt pulley axle and pass.This guide portion 12 has the diameter that increases progressively from the direction away from said bearing hole 11.That is to say to have bigger diameter, so, can make things convenient for the belt pulley shaft alignement in the direction that faces the installation of belt pulley axle.
Distinguishingly, in this mode of execution, the diameter of bearing hole 11 is 60 millimeters, and guide portion 12 is at the maximum diameter that has 64.5 millimeters away from the part of bearing hole 11.
In this mode of execution, the outer edge side of belt pulley 10 includes belt gear 13, is used for cooperating with external belt, increases the frictional force between belt pulley and the belt.
Distinguishingly, the quantity of belt gear 13 is set to 5.
Definition has the groove 14 of inverted trapezoidal shape between the adjacent belt pulley, and in concrete embodiment, belt gear 13 has the cross-section area that successively decreases from the direction away from bearing hole 11.So, also just reduce the area of contact between belt gear 13 and the belt, increased frictional force.
The present invention is through above-mentioned mode of execution; Have following beneficial effect: through being arranged at the belt pulley axle that belt pulley 10 separates, can conveniently carry out the replacing of belt pulley axle, and; The guide portion 12 of guiding belt pulley axle is set on the belt pulley 10, makes that the process of changing the belt pulley axle is more smooth.
Be to be understood that; Though this specification is described according to mode of execution; But be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technological scheme in each mode of execution also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
