Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Be structural representation of the present utility model as shown in Figures 1 to 4,
Reference character is wherein: bonnet main body 1, annular groove 1a, filler opening 11, oil inlet passage 11a, oil outlet 12, oil discharge passage 12a, positioning pin hole 13, bearing mounting hole 14, oil distribution casing 2, oil distribution casing positioning ring 3, locating slot 3a, stepped part 3b, chamfering 31, locating stud 4, bearing 5.In Fig. 3, the direction of arrow represents the loading direction of oil distribution casing positioning ring 3.
As shown in Figures 1 to 4,
A kind of oil distribution casing position structure of plunger pump bonnet, include bonnet main body 1 and oil distribution casing 2, bonnet main body 1 is axially shaped with the bearing mounting hole 14 of the coaxial axis hole 2a in described oil distribution casing 2 center, bearing 5 is provided with in bearing mounting hole 14, bonnet main body 1 is provided with and the oil distribution casing positioning ring 3 of described bonnet main body 1 in split-type structural, oil distribution casing positioning ring 3 is shaped with the locating slot 3a suitable with the cylindrical of described oil distribution casing 2, between bonnet main body 1 and oil distribution casing 2, is also provided with locating stud 4.
In embodiment, bonnet main body 1 offers annular groove 1a, oil distribution casing positioning ring 3 is embedded in this annular groove 1a.
In embodiment, the middle part of oil distribution casing positioning ring 3 is formed with stepped part 3b, and the height of this stepped part 3b is lower than the degree of depth of described annular groove 1a.
Design like this, when oil distribution casing positioning ring 3 is loaded in annular groove 1a, stepped part 3b can enter in annular groove 1a completely, and the assembling of projection to oil distribution casing 2 avoiding stepped part 3b has an impact; After oil distribution casing 2 has assembled, its surface is close to mutually with the surface of bonnet main body 1.
