Description

Novel inner ball cage

Technical Field

The utility model belongs to the technical field of machinery, a novel interior ball cage is related to.

Background

The inner ball cage comprises a cylindrical body, one end of the body is connected with the intermediate shaft, and the other end of the body is sealed through an end cover.

The body passes through the fastener with the end cover in the interior ball cage that has now and is connected, and in order to guarantee connection stability, the quantity of fastener is a plurality of, and the quantity is more fastener leads to loading and unloading loaded down with trivial details, in case partial fastener is connected insecure in the manual connection process moreover, can directly influence the stability of whole interior ball cage.

Moreover, the relatively large number of fasteners also makes the overall inner cage less compact.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a high and compact structure's of stability novel interior ball cage.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a novel inner ball cage, is including the body that is the tube-shape, and body tip department is connected with its confined end cover, its characterized in that, body port department has and is the recessed constant head tank of annular, and the inside cavity and the one end opening of being of above-mentioned end cover, the open end of end cover inlays in constant head tank department and makes end cover and this body coupling, still have between end cover and the body can be with the sealed seal structure of both junctions.

The inventive general of this interior ball cage is connected the end cover in the constant head tank department of body, and such structure enables the junction of body and end cover to be hidden, has effectually improved its compact structure nature, and stability still is than higher moreover.

Meanwhile, the sealing performance of the joint of the end cover and the body can be effectively improved through the sealing structure.

In foretell novel interior ball cage, constant head tank port department has and is annular convex fender edge, and the above-mentioned end cover open end outside has and is annular convex hasp, and above-mentioned hasp inlays in constant head tank department and the hasp tip supports and leans on keeping off the edge.

The end caps are suitably resilient materials such as: copper. In can be smooth and easy embedding constant head tank after the hasp warp under the exogenic action, in case behind the hasp embedding constant head tank, the hasp restores the original shape and makes its tip support and lean on keeping off the edge, finally guarantees end cover and body stable connection.

In the novel inner ball cage, the blocking edge and the body are of an integrated structure.

In the novel inner ball cage, the hook and the end cover are of an integrated structure.

In the novel inner ball cage, the included angle between the outer side of the hook and the side wall of the positioning groove is 10-30 degrees.

In the novel inner ball cage, the included angle between the inner side of the hook and the side wall of the positioning groove is 40-60 degrees.

In the novel inner ball cage, the sealing structure comprises a contact surface and a sealing ring, wherein the contact surface is inclined on the inner side of the hook, the sealing ring is positioned in the positioning groove, and the contact surface is abutted against the sealing ring.

The structure can ensure that enough space is reserved between the hook and the side wall of the positioning groove for installing the sealing ring.

In the novel inner ball cage, the sealing ring is made of rubber material.

Compared with the prior art, this novel interior ball cage does not occupy extra space because the junction of hasp and constant head tank is located inside the body, consequently, its compact structure and stability are high.

Fig. 1 is a schematic sectional structure diagram of the novel inner ball cage.

In the figure, 1, a body; 1a, a positioning groove; 1b, blocking edges; 2. an end cap; 2a, hooking; 3. and (5) sealing rings.

Detailed Description

As shown in figure 1, this novel inner ball cage is including being the body 1 of tube-shape, and body 1 tip department is connected with its confined end cover 2, body 1 port department has and is the concave constant head tank 1a of annular, and above-mentioned end cover 2 is inside to be cavity and one end opening, the open end of end cover 2 inlays in constant head tank 1a department and makes end cover 2 be connected with body 1, still have between end cover 2 and the body 1 and can be with the sealed seal structure in both junctions.

The port of the positioning groove 1a is provided with a blocking edge 1b which is annular and convex, the outer side of the opening end of the end cover 2 is provided with an agraffe 2a which is annular and convex, and the agraffe 2a is embedded in the positioning groove 1a and the end part of the agraffe 2a is abutted against the blocking edge 1 b.

The blocking edge 1b and the body 1 are of an integrated structure.

The hook 2a and the end cover 2 are of an integrated structure.

The included angle between the outer side of the hook 2a and the side wall of the positioning groove 1a is 10-30 degrees.

The included angle between the inner side of the hook 2a and the side wall of the positioning groove 1a is 40-60 degrees.

The sealing structure comprises a contact surface and a sealing ring 3, wherein the contact surface is inclined on the inner side of the hook 2a, the sealing ring 3 is positioned in the positioning groove 1a, and the contact surface is abutted against the sealing ring 3.

The sealing ring 3 is made of rubber materials.
