Description
Technical field
The utility model is related to a kind of belt pulley, particularly relates to a kind of rotation friction small and can be to belt pulley and belt
Lowered the temperature, so as to the belt pulley for increasing the service life.
Background technology
Belt pulley is the instrument that will be converted into linear motion, and existing belt pulley is general by pulley body and one
Body is arranged at the belt grooves composition of pulley body periphery, and axis hole is provided with the middle part of pulley body.Belt pulley is in transmission process
In, the frictional force usually relied between belt pulley bottom or side and balata belt is driven, and can be produced during friction a large amount of
Heat, these heats are accumulated in belt grooves and balata belt, it is difficult to disperse, temperature when making belt work is greatly improved,
The rate of ageing of balata belt is accelerated, its service life is influenceed.For this patent 200810141448X discloses a kind of with logical
The belt pulley of wind effect, the belt grooves of the belt pulley are provided with ventilating opening, and the belt pulley of this structure can reach to a certain extent
To the effect of cooling, but its effect is unsatisfactory.When rotating, wind can enter in belt grooves belt pulley simultaneously from two-port,
But because the aperture of ventilating opening two-port is identical, therefore can be cancelled out each other from the opposite wind of the both direction of two-port entrance,
Hot-air after heat exchange can be accumulated in inside belt grooves, and this allows for the big heavy discount of cooling-down effect.
In addition, existing belt pulley is typically all that directly tumbler is attached with axis hole, this belt pulley turns
Efficiency of movement is low, rotating speed is generally slower.In order to overcome this problem, also there is the belt pulley for being mounted with bearing on existing market, though
Rotational efficienty is greatly so improved, but the shape of the radial section of the interior rolling of this bearing and outer raceway is often semicircle
Shape, steel ball and inside and outside raceway sphere-contact, the structural bearing capacity are poor, and when load increases, contact stress increases so as to increase
The possibility that bearing fatigue is peeled off, simultaneously because contact stress increase causes the heating of bearing, causes the service life of bearing
Reduce.
Utility model content
The utility model provides a kind of belt pulley, and its main purpose is that the belt pulley for overcoming prior art to exist is lowered the temperature
Effect difference and the low defect of pulley rotation efficiency.
The technical solution of the utility model is as follows：
A kind of belt pulley, including pulley body and bearing, the bearing are installed on the middle part of pulley body, the skin
The outer ring of belt wheel body forms belt grooves, and axial ventilation slot, the ventilation slot are uniformly offered on the bottom surface of the belt grooves
Form left ventilating opening and right ventilating opening, left ventilating opening respectively through pulley body and on two lateral surfaces of pulley body
Aperture more than right ventilating opening aperture.
Further, from left ventilating opening, ventilating opening is gradually reduced to the right in the aperture of the ventilation slot.
Further, the bottom surface of the belt grooves is additionally provided with the groove of radial direction, and the groove is surrounded on the bottom surface of belt grooves.
The flowing of air in belt grooves is more beneficial for, radiating and cooling effect is further enhanced.
Further, one layer of frosted layer is formed on the inwall of the belt grooves.
Further, the bottom of the belt grooves is provided with one layer of wear-resisting carbide layers.
Further, the bearing includes inner ring, outer ring and ball, and inner ring is provided with interior raceway, and outer ring is provided with outer rolling
The radial section of road, the interior raceway and outer raceway is triangular in shape, and the ball is tangent with inside and outside raceway respectively.Ball and
It is tangent between inside and outside raceway so that contact area diminishes, frictional force during rolling is reduced, not only the more conducively rolling of ball,
And the heat produced by friction is decreased, so as to lift service life.
From above-mentioned to description of the present utility model, compared to the prior art, the utility model has the following advantages that：It is left
The intake of ventilating opening is significantly greater than the intake of right ventilating opening, and wind can be from left ventilating opening ventilating opening one-way flow to the right, favorably
In the quick flowing of air in belt grooves, so that cooling-down effect is obviously improved.

Specific embodiment
Specific embodiment of the present utility model is illustrated with reference to the accompanying drawings.
Embodiment one
Reference picture 1, a kind of belt pulley, including pulley body 1 and bearing 2, the bearing 2 are installed on pulley body 1
Middle part, the outer ring of the pulley body 1 forms belt grooves 3, and belt 4 (usually rubber) is arranged in belt grooves 3.In order to
Enhancing frictional force, forms one layer of frosted layer (being not drawn into figure) on the inwall of the belt grooves 3；In order to strengthen anti-wear performance, institute
The bottom for stating belt grooves 3 is provided with one layer of wear-resisting carbide layers.
Axial ventilation slot 5, the ventilation are uniformly offered referring concurrently to Fig. 2 and Fig. 3, on the bottom surface of the belt grooves 3
Groove 5 forms left ventilating opening 51 and right ventilating opening through pulley body 1 and on two lateral surfaces of pulley body 1 respectively
