Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wheel hubs and relates to a high-strength planetary carrier outer hub. Background Art
[0002] In the production process of wheel hub, the wheel hub blank needs to be fixed first, so as to facilitate the spinning process of the processing equipment in the equipment. Generally, the wheel hub blank needs to be placed in a special holder first, and then spun as the equipment rotates. However, in the actual operation process, the wear of the assembly part can easily cause the wheel hub to tilt slightly after placement, resulting in unstable placement, spinning errors, and errors in the wall thickness of the wheel hub, thus affecting its overall use strength. At the same time, the processing equipment cannot meet the processing needs of multiple models. Summary of the invention

[0005] In the above-mentioned high-strength planetary carrier outer hub, the stabilizing unit is a stabilizing column, the hub body is sleeved on the stabilizing column and slidably cooperates with it, and the stabilizing column is located on the outer peripheral wall at the lower end and is provided with a convex ring portion that protrudes radially outward and is fitly connected to the hub body.
[0006] In the above-mentioned high-strength planet carrier outer hub, the stabilizing column is hollow, and the inner wall of the stabilizing column is provided with a limiting groove arranged along the length direction thereof.
[0007] In the above-mentioned high-strength planetary carrier outer hub, an axially outward protruding portion is provided on the end face where the convex ring portion fits with the hub body, an axially inwardly recessed groove for the convex ring portion to be embedded and installed is provided on the end face where the hub body fits with the convex ring portion, and an assembly hole for the protruding portion to be embedded and installed is provided on the end face of the hub body located at the recessed groove.
[0008] In the above-mentioned high-strength planetary carrier outer hub, an axially inwardly recessed mounting groove is provided on the end surface of the hub body at the assembly hole, and a limiting ring washer connected to the upper end of the protrusion is provided.
[0009] Compared with the prior art, the high-strength planetary carrier outer hub has the following advantages:
[0010] 1. A stabilizing unit connected to the hub body and improving assembly stability is disposed at the cavity of the hub body. The above-mentioned structure reduces wear and tear while making it more stable. BRIEF DESCRIPTION OF THE DRAWINGS
