Abstract
The utility model relates to a heat dissipation belt pulley. The heat dissipation belt pulley comprises a body, wherein the outer surface of the body is provided with a cylindrical face, heat dissipation holes are formed in the cylindrical face of the body, a layer of oil blocking net is arranged in the middle of the inner portion of each heat dissipation hole, each heat dissipation hole is of a circular truncated cone shape, the diameter of the opening in the outer side of each heat dissipation hole is larger than the diameter of the opening in the inner side of each heat dissipation hole, blind holes are symmetrically formed in the end faces of the body, a supporting barrel is arranged on one side of the body, and a supporting boss is arranged at the outer end portion of the supporting barrel. The heat dissipation belt pulley is simple in structure, heat produced through friction can be dissipated timely and effectively through the heat dissipation holes, meanwhile, due to the fact that the oil blocking net is arranged in each heat dissipation hole, oil on a rotating shaft is prevented from flowing onto a belt through the heat dissipation holes in the transmission process, and the rotating shaft is prevented from slipping.
Description
Technical field
The utility model relates to the engine component field, relates in particular to a kind of heat radiation belt pulley.
Background technique
The belt drive system of motor specifically carrys out transmitting torque by belt pulley and belt, existing belt pulley is in transmission process, frictional force between main dependence belt pulley bottom or side and belt is carried out transmission, these frictions can produce very large heat, heat mainly is gathered on belt grooves and belt, in situation about drawing badly, is difficult to leave, and the temperature while making belt work improves greatly, accelerated the aging speed of belt, belt shortens working life greatly.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of perfect heat-dissipating is provided, can have improved the belt heat radiation belt pulley in working life.
The utility model is to be achieved through the following technical solutions: a kind of heat radiation belt pulley, comprise that outer surface has the body of a cylndrical surface, and on the cylndrical surface of described body, have radiation hole, the bosom of described radiation hole is provided with one deck leakproof oil net.
Further, described radiation hole is frustoconic shape, and the outer openings diameter of radiation hole is greater than inboard opening diameter.
Further, the end surface symmetric of described body is provided with blind hole.
Further, a side of described body is provided with the support cylinder, and the outer end of described support cylinder is provided with support rim.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, by radiation hole is set, the dissipation of heat that can timely and effectively friction be produced is gone out, leakproof oil net is set simultaneously in radiation hole, avoid in transmission process, the fluid in rotating shaft enters on belt by radiation hole, avoids skidding.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of heat radiation belt pulley of the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of a kind of heat radiation belt pulley of the utility model.
Described a kind of heat radiation belt pulley, comprise that outer surface has the body 1 of a cylndrical surface, on the cylndrical surface of described body 1, have radiation hole 2, the bosom of described radiation hole 2 is provided with one deck leakproof oil net 3, described radiation hole 2 is frustoconic shape, and the outer openings diameter of radiation hole 2 is greater than inboard opening diameter.
By radiation hole 2 is set, the dissipation of heat that can timely and effectively friction be produced is gone out, and simultaneously at the interior leakproof oil net 3 that arranges of radiation hole 2, avoids in transmission process, and the fluid in rotating shaft enters on belt by radiation hole 2, avoids skidding.
The end surface symmetric of described body 1 is provided with blind hole 4, alleviates the weight of belt pulley, saves material.
One side of described body 1 is provided with support cylinder 5, and the outer end of described support cylinder 5 is provided with support rim 6, and is for convenience detach.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
