Abstract
The utility model discloses a high-wear-resistant automobile engine fuel injection pump belt wheel. The automobile engine fuel injection pump belt wheel is a member which takes powder metallurgy as a main body, is prepared by employing a powder metallurgy process, and comprises a wheel body, and a rim coaxial with the wheel body, wherein wheel teeth are formed on an outer wall of the rim and are coaxial with a central hole of the wheel body; a toothed side face of the wheel teeth is in fillet transition with the toothed top surface and the tooth root; and an outer wall of the wheel teeth is provided with a wear-resistant composite layer. The material utilization rate is high, and the labor hour and material cost are saved; the stress concentration of the wheel tooth part is obviously reduced; and the wear resistance and service life of the automobile engine fuel injection pump belt wheel are obviously improved.
Description
Technical field
The utility model relates to a kind of Injection Pump belt wheel, and more particularly, the utility model relates to a kind of motor car engine Injection Pump belt wheel that adopts powder metallurgy process to make.
Background technique
Motor car engine Injection Pump belt wheel is discoid part, comprises wheel body, the wheel rim coaxial with wheel body, is provided with the gear teeth at the wheel rim outer wall.Existing motor car engine Injection Pump belt wheel is generally middle-carbon steel or cast iron, and through processing, the part amount of finish is large, and waste of material is also more, and cost of material is higher; The flank of the gear teeth and Topland, tooth root section intersect wedge angle, produce easily stress and concentrate; In addition, gear teeth wear resistance is relatively poor, causes motor car engine Injection Pump belt wheel shorter working life.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of stock utilization high, and wheel tooth position stress is concentrated little, the high abrasion motor car engine Injection Pump belt wheel that gear teeth wear resistance is good.
The utility model is achieved through the following technical solutions technical goal.
High abrasion motor car engine Injection Pump belt wheel comprises wheel body, the wheel rim coaxial with wheel body; Be provided with the gear teeth at described wheel rim outer wall, coaxial with the center hole of wheel body; Its improvements are: described motor car engine Injection Pump belt wheel is the member take powder metallurgy as main body; The flank of the described gear teeth and Topland, Fillet transition; Described gear teeth outer wall is provided with wear-resistant composite bed.
The further technological scheme of the utility model is: the described wear-resistant composite bed rare earth compound composite bed that is.
The utility model further technological scheme is: described wear-resistant composite bed thickness is 0.4-1.8mm.
The utility model compared with prior art has following good effect:
1, the flank of the gear teeth and Topland, Fillet transition have significantly reduced the stress of gear teeth tooth section and have concentrated.
2, adopt the powder metallurgical technique preparation, only need a small amount of machining, stock utilization is high, saves man-hour and cost of material.
3, gear teeth outer wall is provided with wear-resistant composite bedly, significantly improves wear resistance and the working life of motor car engine Injection Pump belt wheel.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view among Fig. 1.
Fig. 3 is the II part enlarged diagram among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with embodiment.
High abrasion motor car engine Injection Pump belt wheel shown in the drawings, motor car engine Injection Pump belt wheel is the member take powder metallurgy as main body, comprises wheel body 2, the wheel rim 3 coaxial with wheel body 2; Be provided with the gear teeth 5 at wheel rim 3 outer walls, coaxial with the center hole 1 of wheel body 2; The flank of the gear teeth 5 and Topland, Fillet transition; The gear teeth 5 outer walls are provided with wear-resistant composite bed 4; Preferred version is: wear-resistant composite bed 4 are the rare earth compound composite bed, and its thickness is 0.4-1.8mm, and in the present embodiment, wear-resistant composite bed 4 thickness is 1.2mm.
The utility model adopts the powder metallurgical technique preparation, only needs a small amount of machining, and stock utilization is high, saves man-hour and cost of material; The flank of the gear teeth 5 and Topland, Fillet transition have significantly reduced the stress of gear teeth tooth section and have concentrated; It is wear-resistant composite bed 4 that the gear teeth 5 outer walls are provided with, and significantly improves wear resistance and the working life of motor car engine Injection Pump belt wheel.
