Abstract
The invention relates to a heat radiating belt pulley. The heat radiating belt pulley comprises a body the outer surface of which is cylindrical surface, wherein a heat radiating hole is formed in the cylindrical surface of the main body; an oil baffle net is arranged in the middle of the interior of the heat radiating hole; the heat radiating hole is represented as a circular truncated cone; the diameter of an opening formed in the outer side of the heat radiating hole is greater than the diameter of an opening formed in the inner side; blind holes are symmetrically formed in the end face of the main body; a supporting drum is arranged at one side of the main body; and a supporting boss is arranged at the outer end of the supporting drum. The heat radiating belt pulley is simple in structure, and heat energy generated from friction is outwardly radiated through the arrangement of the heat radiating hole; and meanwhile, through the oil baffle net in the heat radiating hole, oil liquid on a rotating shaft is prevented from entering into a belt through the heat radiating hole in a transmission process, thus avoiding slip.
Description
Technical field
The present invention relates to the engine component field, relate in particular to a kind of heat radiation belt pulley.
Background technique
The belt drive system of motor specifically comes 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 the belt is carried out transmission, these frictions can produce very big heat, heat mainly accumulates on belt grooves and the belt, is difficult to leave under the situation about drawing badly, and the temperature when making belt work improves greatly, accelerated the aging speed of belt, belt shortens working life greatly.
Summary of the invention
The objective of the invention 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 present invention is 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 have radiation hole on the cylndrical surface of described body, the bosom of described radiation hole is provided with one deck leakproof oil net.
Further, described radiation hole is a frustoconic shape, and the outer openings diameter of radiation hole is greater than inboard opening diameter.
Further, the end face of described body is arranged with blind hole.
Further, a side of described body is provided with the support tube, and the outer end of described support tube is provided with support rim.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, by radiation hole is set, the heat that can timely and effectively friction be produced distributes, leakproof oil net is set in radiation hole simultaneously, avoid in transmission process, the fluid in the rotating shaft enters on the belt by radiation hole, avoids skidding.
Description of drawings
Fig. 1 is the structural representation of a kind of belt pulley that dispels the heat of the present invention.
Embodiment
In order to make purpose of the present invention, technological scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, Fig. 1 is the structural representation of a kind of belt pulley that dispels the heat of the present invention.
Described a kind of heat radiation belt pulley, comprise that outer surface has the body 1 of a cylndrical surface, have radiation hole 2 on the cylndrical surface of described body 1, the bosom of described radiation hole 2 is provided with one deck leakproof oil net 3, described radiation hole 2 is a frustoconic shape, and the outer openings diameter of radiation hole 2 is greater than inboard opening diameter.
By radiation hole 2 is set, the heat that can timely and effectively friction be produced distributes, and simultaneously leakproof oil net 3 is set in radiation hole 2, avoids in transmission process, and the fluid in the rotating shaft enters on the belt by radiation hole 2, avoids skidding.
The end face of described body 1 is arranged with blind hole 4, alleviates the weight of belt pulley, saves material.
One side of described body 1 is provided with support tube 5, and the outer end of described support tube 5 is provided with support rim 6, and is for convenience detach.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
