Abstract

The utility model relates to a protection cover for an end part of a bearing, particularly technology of the protection cover of the bearing. The utility model comprises a bottom plate and an annular flange edge which is integrally arranged on the outer margin of the bottom plate, wherein the flange edge is uniformly distributed with connecting holes. The circle centers of the connecting holes have the same distance with the centers of the bottom plate. Both sides of the connecting holes are respectively provided with an annular wall body. The annular wall bodies are respectively protruded out of the same side of the flange edge. The bottom plate, the flange edge and the annular wall bodies are made of plastic. The utility model has the advantage that the product can be shaped by disposable injection molding, compared with the traditional cast iron, a plurality of working procedures of casting, shaping, grinding, milling, etc. are saved, the production flow is simplified, and the production cost is saved; the product has good integrity, strong firmness and toughness, good wear resistance and corrosion resistance, light weight and stable performance; the annular wall bodies on both of the two sides of the connecting holes can perform the complete sealing function, and a sealing ring is not needed in installation, which fundamentally and effectively solves the problem of oil leakage; the assembly and the use are simple, and the production efficiency can be raised.

Description

The bearing end shield

Technical field

The utility model relates to bearing, particularly the guard shield technology of bearing.

Background technique

Be widely used in the bearing of forging various engineering goods such as pressing punch press, lathe, milling machine, grinding machine, numerical control machine tool of various models,, generally all be provided with guard shield in its end in order to realize purpose of design.Present guard shield is all made by ironcasting, the circular flange edge that is arranged on the base plate outer rim by circular bottom plate and connecting body is formed, the uniform attachment hole that can be connected on flange edge with bearing, need in the inboard of attachment hole during assembling, on the flange of bearing surface, add the ring packing pad, because most of gasket seals are that paper is made, the wear resistance of material is bad, uses to occur oil leakage phenomenon soon, has seriously influenced the normal operation of machinery.

The model utility content

The utility model purpose is to design the bearing end shield that a kind of wear resistance is good, sealing is strong.

The utility model comprises that base plate, disjunctor are arranged on the shape flange edge of base plate outer rim, uniform attachment hole on flange edge, the center of circle of described attachment hole and the center of base plate are equidistant, both sides at attachment hole are provided with the ring-type body of wall respectively, described ring-type body of wall all is raised in the same side of flange edge, and described base plate, flange edge, ring-type body of wall are that plastics are made.

The utlity model has following superiority:

1, product can disposable injection molded, compares with traditional cast iron, and all multiple operation such as saved casting, car, grind, mill have been simplified production procedure greatly, have saved cost of production.

2, product good integrity is firm, toughness is strong, wear-resisting, rotproofness good, and is in light weight, stable performance.

3, the ring-type body of wall of design in the attachment hole both sides can play the effect of sealing fully, do not need seal ring during installation, fundamentally solved the problem of leakage of oil effectively.

4, assembling is used simply, can enhance productivity.

In addition, the utility model also is provided with tank filler sleeve on base plate.Can be conveniently to the maintenance of bearing.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to cut-away view.

Specific embodiment

As shown in the figure, the utility model is formed by an injection moulding of plastics.Offer tank filler sleeve 4 on the base plate 1, annular flange limit 2 is set at base plate 1 outer rim disjunctor, uniform eight attachment holes 3 on flange edge 2, the center of the center of circle of each attachment hole 3 and base plate 1 is equidistant.

In the inboard of attachment hole 3 ring-type body of

wall

6 and 7 are set, at the arranged outside ring-type body of wall 5 of attachment hole 3, ring-type body of

wall

5,6,7 all is raised in the side towards bearing of flange edge 2.

The utility model profile is not limited to the circle among the figure, also can be square or other geometrical shapies.

Claims

1, bearing end shield, comprise that base plate, disjunctor are arranged on the annular flange limit of base plate outer rim, uniform attachment hole on flange edge, the center of circle of described attachment hole and the center of base plate are equidistant, it is characterized in that the ring-type body of wall being set respectively in the both sides of attachment hole, described ring-type body of wall all is raised in the same side of flange edge, and described base plate, flange edge, ring-type body of wall are that plastics are made.

2, according to the described bearing end shield of claim 1, it is characterized in that on base plate, being provided with tank filler sleeve.
