Abstract
The utility model discloses a powder metallurgy eccentric ring which comprises a hole, and an eccentric ring which is eccentric relative to the center of the hole, wherein the eccentric ring is an annular member which takes powder metallurgy as a main body; one part of the outer wall of the middle upper part of the eccentric ring is inwards concave along the peripheral direction so as to form an inner eccentric ring coaxial with the eccentric ring; and wear-resistant composite layers are formed on the inner wall of the hole, an outer wall of the eccentric ring and an outer wall of the inner eccentric ring. The powder metallurgy eccentric ring is high in material utilization rate, the labor hour is saved, and the machining precision can be economically achieved; and moreover, the wear-resistant composite layers are formed on the inner wall of the hole, the outer wall of the eccentric ring and the outer wall of the inner eccentric ring and are rare earth compound composite layer, and due to the wear-resistant composite layers, the wear resistance of the eccentric ring can be obviously improved.
Description
Technical field
The utility model relates to a kind of eccentric wheel, and more particularly, the utility model relates to a kind of eccentric wheel that adopts powder metallurgy process to make.
Background technique
Need to realize different actions by two eccentric wheels in the auto steerer, prior art is that two eccentric group are fitted together.Two eccentric wheels of prior art are generally middle-carbon steel or alloyed steel, through processing, heat treatment forms, by heat treatment so that eccentric wheel has certain wear resistance.But such eccentric wheel exists certain deficiency: the one, and the part amount of finish is large, and waste of material is also more; The 2nd, wear resistance is relatively poor; The 3rd, formed by assembling parts, in order to guarantee the rear eccentric precision of assembling, must guarantee the eccentric machining accuracy of assembling the first two and install precision, accuracy of manufacturing requires high, and manufacture cost is high.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of technique simple, and stock utilization is high, and comparatively economy reaches machining accuracy, the powder metallurgy eccentric ring that wear resistance is good.
The utility model is achieved through the following technical solutions technical goal.
The powder metallurgy eccentric ring comprises the hole, with respect to the eccentric hoop of center, hole off-centre, and its improvements are: described eccentric hoop is the annular component take powder metallurgy as main body; Described eccentric hoop middle and upper part part outer wall is indent in the circumferential direction of the circle, forms the interior eccentric hoop coaxial with eccentric hoop; The surface of described hole inwall, eccentric hoop outer wall, interior eccentric hoop outer wall is provided with wear-resistant composite bed.
The further technological scheme of the utility model is: described wear-resistant composite bed thickness is 0.2-2.2mm.
The utility model further technological scheme is: the described wear-resistant composite bed rare earth compound composite bed that is.
The utility model compared with prior art has following good effect:
1, adopt the powder metallurgical technique preparation, only need a small amount of machining, stock utilization is high, saves man-hour, and comparatively economy reaches machining accuracy.
2, the surface of hole inwall, eccentric hoop outer wall, interior eccentric hoop outer wall is provided with wear-resistant composite bedly, and wear-resistant composite bed is the rare earth compound composite bed, this wear-resistant composite bed wear resistance that significantly improves eccentric hoop.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the plan view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with embodiment.
Powder metallurgy eccentric ring shown in the drawings, comprise hole 3, with respect to the eccentric hoop 1 of hole 3 center off-centre, eccentric hoop 1 is the annular component take powder metallurgy as main body, and eccentric hoop 1 middle and upper part part outer wall is indent in the circumferential direction of the circle, forms the interior eccentric hoop 2 coaxial with eccentric hoop 1; It is wear-resistant composite bed 4 that the surface of hole 3 inwalls, eccentric hoop 1 outer wall, interior eccentric hoop 2 outer walls is provided with, and preferred version: wear-resistant composite bed 4 is the rare earth compound composite bed, and its thickness is 0.2-2.2mm, and in the present embodiment, wear-resistant composite bed 4 thickness is 0.6mm.
The utility model adopts powder metallurgy, only needs a small amount of machining, and stock utilization is high, saves man-hour, and comparatively economy reaches machining accuracy; It is wear-resistant composite bed 4 that the surface of hole 3 inwalls, eccentric hoop 1 outer wall, interior eccentric hoop 2 outer walls is provided with, and this wear-resistant composite bed 4 can significantly improve the wear resistance of eccentric hoop.
Claims (3)
