Consider the description to a plurality of mode of executions of the utility model in conjunction with the drawings, those skilled in the art can have clear more and thorough understanding to the utility model.Wherein:
Fig. 1 shows the stereogram according to the belt pulley of a mode of execution of the utility model; And
Fig. 2 shows an example according to the use cooling fluid of a mode of execution of the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.It will be appreciated that accompanying drawing and following description only are examples, it can not limit protection domain of the present utility model.
Fig. 1 shows the stereogram according to the belt pulley of a mode of execution of the present utility model.
As shown in Figure 1, totally be expressed as 10 according to the belt pulley of a mode of execution of the present utility model, belt pulley 10 is provided with the fluid passage.Fluid can be gas and/or liquid.Usually, can directly use air.
It will be appreciated that although the fluid passage shown in Fig. 1 is radial fluid passages B, this is a preferred implementation of the present utility model.According to multiple other mode of executions of the present utility model, the fluid passage can be any other shape, for example can be coaxial circular fluid passage, also can be from the center of circle to any other shape of circumferential extension, even can form netted.
The advantage of radial fluid passages B is, in the belt pulley rotation, can utilize centrifugal force and make fluid from the center of circle to external diffusion, thereby make the smoothness more of pass through of fluid.
It will be appreciated that although the quantity of the radial fluid passages B shown in Fig. 1 is eight, the utility model is not limited to any specific quantity, those skilled in the art can select the quantity of actual demand as required.
According to preferred implementation of the present utility model, described radial fluid passages B evenly is arranged on the described belt pulley.
It will be appreciated that also although the belt pulley that illustrates 10 is to be the circular belt pulley that axle is rotated with the center of circle, the technical solution of the utility model can be applicable to the wheel of other shapes too, for example solid of rotation of eccentric wheel and any other shape or the like.
According to a mode of execution of the present utility model, as shown in Figure 1, the surface of described belt pulley 10 is provided with the attachment face 14 that contacts with external agency's (for example silicone oil vibration damper in the diesel engine), and described radial fluid passages is arranged on the described attachment face 14.This attachment face 14 plane for having specific thicknesses with respect to the surface of belt pulley like this, is arranged on radial fluid passages B on this attachment face 14 fluid is flowed out from the outer radius of this attachment face with specific thicknesses.Certainly, this attachment face is not necessary, flows out from the outer radius of this belt pulley 10 because radial fluid passages can run through the whole surface of this belt pulley 10.
Further as shown in Figure 1, described belt pulley 10 can also comprise the projection 16 that forms in its surface.According to a preferred implementation of the present utility model, described fluid passage also comprises axial fluid passage A, and described axial fluid passage A is arranged on the described projection 16.In operation, the mechanism of belt pulley 10 outsides (for example silicone oil vibration damper in the diesel engine) can be connected on this projection 16 and (for example be socketed on this projection 16).Although the projection shown in Fig. 1 16 is circular, other shapes, polyhedron for example, irregularly shaped grade can be used, and projection 16 also can be solid.
