Abstract
The utility model discloses a belt pulley component. The belt pulley component comprises a belt pulley and a belt pulley shaft, wherein the belt pulley is provided with a bearing hole, and the belt pulley shaft and the belt pulley are formed in split mode. The bearing hole is provided with a guide portion used to guide the belt pulley shaft to penetrate. Due to the fact that the belt pulley shaft is arranged on the belt pulley in split mode, the belt pulley shaft can be replaced conveniently. In addition, the guide portion used to guide the belt pulley shaft and arranged on the belt pulley enables the process of replacing the belt pulley shaft to be smooth.
Description
Technical field
The utility model belongs to field of mechanical technique, is 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 by driving this belt pulley axle and then driving the running of belt pulley.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.
The model utility content
The purpose of this utility model is to provide the belt pulley that can change belt pulley axle assembly.
For realizing above-mentioned model utility purpose, a kind of belt pulley assembly that the utility model provides, this belt pulley assembly comprises:
Belt pulley comprises bearing hole on it;
The belt pulley axle, described belt pulley axle and belt pulley split form;
Wherein, comprise guide portion on the described bearing hole, be used for guiding described belt pulley axle and pass.
As further improvement of the utility model, the outer edge side of described belt pulley includes the belt gear teeth.
As further improvement of the utility model, the quantity of the described belt gear teeth is set to 5.
As further improvement of the utility model, define the groove that inverted trapezoidal shape is arranged between the described adjacent belt gear teeth.
As further improvement of the utility model, the described belt gear teeth have the cross-section area that successively decreases from the direction away from described bearing hole.
As further improvement of the utility model, the diameter of described bearing hole is 60 millimeters.
As further improvement of the utility model, described guide portion has the diameter that increases progressively from the direction away from described bearing hole.
Compared with prior art, the utility model can conveniently carry out the replacing of belt pulley axle by at the belt pulley axle that is arranged at the belt pulley separation, and, the guide portion of guiding the belt pulley axle is set, so that it is more smooth to change the process of belt pulley axle on the belt pulley.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of belt pulley in the utility model belt pulley assembly.
Embodiment
Below with reference to embodiment shown in the drawings the utility model is described in detail.But these mode of executions do not limit the utility model, 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 the protection domain of the present utility model.
Join Fig. 1, introduce an embodiment of the utility model belt pulley assembly.In the utility model, because the belt pulley axle does not relate to the improvement on the concrete structure, so accompanying drawing omits.In the present embodiment, 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 the present embodiment, this bearing hole 11 is positioned in fact the center of belt pulley 10.
Belt pulley axle and belt pulley 10 splits form, and this belt pulley axle can match with bearing hole 11 purpose that freely splits to reach belt pulley 10 and belt pulley axle.By setting like this, the belt pulley axle can carry out free replacement, and needn't change whole belt pulley 10 assemblies when wearing and tearing or damage occur, and so can reduce production costs.
As preferred embodiment, comprise guide portion 12 on the bearing hole 11, be used for guiding belt pulley axle and pass.This guide portion 12 has the diameter that increases progressively from the direction away from described bearing hole 11.That is to say to have larger diameter in the direction that faces the installation of belt pulley axle, so, can make things convenient for the belt pulley shaft alignement.
Distinguishingly, in the present embodiment, 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 the present embodiment, 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 specific 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 utility model is by above-mentioned mode of execution, has following beneficial effect: by the belt pulley axle that is being arranged at belt pulley 10 and separates, can conveniently carry out the replacing of belt pulley axle, and, the guide portion 12 of guiding belt pulley axle is set, so that it is more smooth to change the process of belt pulley axle on the belt pulley 10.
Be to be understood that, although 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, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
