TECHNICAL FIELD

[0001] The utility model relates to conical roller ball base surface processing, concretely relates to a high -speed rail bearing conical roller ball base surface frock. BACKGROUND

[0002] The frock (such as patent: 201510505100.4 a kind of no magnetic penetration type grinding machine based on the curvature radius of conical roller ball base surface is disclosed) formed by the combination of outer disc, inner disc and isolation disc is prone to wear in use. SUMMARY

[0003] The utility model provides a high -speed rail bearing conical roller ball base surface frock, aims at solving above -mentioned problem.

[0004] A kind of high -speed rail bearing conical roller ball base surface frock, the frock includes outer disc, inner disc, isolation disc, the outer disc, inner disc, isolation disc are combined together, several conical rollers are placed between outer disc and inner disc, supported on isolation disc, end stretches out outer disc and inner disc, each conical roller is spaced apart by the tooth of isolation disc;When using, the outer disc is forward, the inner disc is reversed, the isolation disc is forward or reversed, each conical roller is on the side surface of the tooth of isolation disc, i.e. support surface, does revolution and rotation, each conical roller end is polished by a grinding wheel, the support surface of the isolation disc is inclined angle A;Research finds that each conical roller is on the side surface of the tooth of isolation disc, i.e. support surface, does revolution and rotation, and slightly deflection occurs, which exacerbates the wear of inner disc (mainly), outer disc (mainly) and isolation disc;Why does each conical roller slightly deflect? Further analysis shows that the problem lies in the support surface of the isolation disc, therefore, the support surface of the isolation disc is parallel to reference surface, and the reference surface is the plane where the center of the isolation disc and the center of the conical roller on the support surface of the isolation disc are located.

[0005] The outer disc inner wall is a convex circular arc conical surface, the inner disc outer wall is a concave circular arc conical surface, and the middle part of each conical roller is in contact with the convex circular arc conical surface, and the two sides are in contact with the concave circular arc conical surface.

[0006] The outer disc inner wall is provided with a ring groove I at the middle position, and the ring groove I is embedded with a diamond.

[0007] The inner disc outer wall is provided with a ring groove II at the middle position.

[0008] The utility model has the advantages of reasonable design and simple structure, and is not prone to wear when used for processing the ball base surface of each conical roller. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 It is a frock structure schematic diagram.

[0010] Fig. 2 This is a schematic diagram of the isolation disk structure.

[0011] The tooling in the diagram includes 1, outer disc 1-1, inner disc 1-2, isolation disc 1-3, tapered roller 2, and grinding wheel 3. Detailed Implementation

[0012] like Figs. 1-2 As shown, a high-speed rail bearing tapered roller ball base surface fixture is provided. The fixture 1 includes an outer disk 1-1, an inner disk 1-2, and an isolation disk 1-3. The outer disk 1-1, inner disk 1-2, and isolation disk 1-3 are assembled together. Several tapered rollers 2 are placed between the outer disk 1-1 and the inner disk 1-2, supported on the isolation disk 1-3, and their ends extend beyond the outer disk 1-1 and the inner disk 1-2. Each tapered roller 2 is separated by the teeth of the isolation disk 1-3. The inner wall of the outer disk 1-1 is a convex arc conical surface, and the outer wall of the inner disk 1-2 is a concave arc conical surface. The middle part of each tapered roller 2 contacts the convex arc conical surface, and the two sides contact the concave arc conical surface. An annular groove is provided in the middle position of the inner wall of the outer disk 1-1, and a diamond is embedded in the annular groove I. An annular groove II is provided in the middle position of the outer wall of the inner disk 1-2.

[0013] In use, the outer disc 1-1 rotates clockwise, the inner disc 1-2 rotates counterclockwise, and the isolation disc 1-3 rotates clockwise or counterclockwise. Each tapered roller 2 rests on one side of the teeth of the isolation disc 1-3, i.e., the support surface, and revolves and rotates. The ends of each tapered roller 2 are ground by a grinding wheel 3. The support surface of the isolation disc 1-3 is inclined at an angle A. The support surface of the isolation disc 1-3 is parallel to the reference plane, which is the plane where the center of the isolation disc 1-3 and the center of the tapered roller 3 resting on the support surface of the isolation disc 1-3 are located.

[0014] Grinding of the support surface of the aforementioned isolation plate:

[0015] 1) Grind a beveled surface with an angle of A at the support surface of the isolation plate;

[0016] 2) Place a conical roller inside the isolation disc and rest it on the inclined surface at the aforementioned angle A;

[0017] 3) Using the plane where the center of the isolation disc and the center of the aforementioned tapered roller are located as the reference plane, grind the inclined surface at the aforementioned inclination angle A to make it parallel to the reference plane;

[0018] This involves grinding the support surface of the isolation plate.

[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
