Abstract
The utility model relates to an easily replaced antiskid belt pulley used for a motor of an oil pumping device in oil field. Three axial through grooves (3) are evenly distributed on an inner hole of a belt pulley body (1) along the circumference, and four annular grooves (4) are evenly distributed on the inner hole of the belt pulley body (1) in the axial direction; four eyelets (5) are evenly drilled on the bottom of each pulley groove (2) along the circumference, the upper parts of the eyelets (5) are provided with screw threads and are screwed with screw bolts, and the lower ends of the eyelets (5) are communicated with the through grooves (3). The utility model has the advantages of novel structure, remote possibility of slippage, high transmission efficiency and easy replacement, and brings convenience for the production and the management of the oil pumping device.
Description
The utility model relates to a kind of easy replacing anti-slip belt pulley that is used for the oil-field oil pumper motor.
Belt pulley is one of vitals of motor of oil extractor.The belt grooves of common belt pulley is linear, and groove face is straight, thereby friction ractor is little, and non-skid property is poor, and especially at sleety weather, its friction ractor falls sharply, and belt easily skids, and causes transmission efficiency to reduce greatly, and the belt phenomenon takes place to burn often.In addition, it is very difficult that this kind belt pulley is changed, need with taking off trochus it be taken off down again with the roasting hot belt pulley of electrogas welding, thereby this work time and effort consuming not only, and often belt pulley is caused damage.
The purpose of this utility model is to provide a kind of easy replacing anti-slip belt pulley, and this kind belt pulley is easy to change, and the friction ractor between race and the belt is bigger, can prevent to skid.Utilize it can overcome the deficiency of existing belt pulley.
The utility model is to realize like this.This belt pulley is made up of wheel body (1) and race (2), it is characterized in that: wheel body (1) endoporus removes keyway outer circumference and also is evenly equipped with 3 axial pass troughs (3), then is evenly equipped with 4 road circular grooves (4) on axially; Each race (2) bottom evenly is drilled with 4 eyelets (5) along circumference, and eyelet (5) top is threaded and screw in bolt, and the lower end communicates with groove (3).The eyelet of this belt pulley wheel groove bottom setting is used for adding loosening liquid, and eyelet top DRIVE SCREWS can prevent that foreign material such as belt bits from entering in the wheel body internal diameter groove.When changing belt pulley, the race screw is unloaded, inject loosening liquid, belt pulley promptly is easy to change.In addition, uneven because the groove face of this belt pulley is made curved, increased the friction of groove face and belt, reduced belt slippage, thereby helped improving the transmission efficiency of belt pulley, prolongation belt working life.
The utility model novel structure, its advantage are to be difficult for skidding, the transmission efficiency height, and be easy to change, bring great convenience for the pumping unit production management.
Fig. 1 is the utility model structural representation.
Fig. 2 is its side view.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
It is 1: 8～10 taper that 3 axial pass troughs (3) that are provided with on this belt pulley wheel body (1) endoporus are tapering.Race (2) groove face is made the sinusoidal that oscillating quantity is 1mm, and each is taken turns groove bottom and is evenly equipped with 4 eyelets (5) (eyelet that only draws among the figure is as representative, and all the other do not draw), and eyelet top band M8 screw thread is in order to screw in flush bolt.
Claims (3)
1. easily change the anti-slip belt pulley for one kind, this belt pulley is made up of wheel body (1) and race (2), it is characterized in that: wheel body (1) endoporus also is evenly equipped with 3 axial pass troughs (3) except that keyway outer circumference, then is evenly equipped with 4 road circular grooves (4) on axial; Each race (2) bottom evenly is drilled with 4 eyelets (5) along circumference, and eyelet (5) top is threaded and screw in bolt, and the lower end communicates with groove (3).
2. easy replacing anti-slip belt pulley according to claim 1 is characterized in that, it is 1: 8～10 taper that 3 axial pass troughs (3) that are provided with on this belt pulley wheel body (1) endoporus are tapering.
3. easy replacing anti-slip belt pulley according to claim 1 is characterized in that race (2) groove face is made the sinusoidal that oscillating quantity is 1mm, and uniform 4 the eyelet tops of wheel groove bottom are threaded.
