Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] like Figure 1-2 As shown, the forging of the outer ring of the bearing used in the vehicle includes a forging body 1. One end of the forging body 1 is provided with a first tapered blind hole 2, and the other end is provided with a second tapered blind hole 3. The first tapered blind hole 2 is connected to the The second blind tapered hole 3 is arranged symmetrically so that a disc-shaped body 4 is formed between the first blind tapered hole 2 and the second blind tapered hole 3, between the bottom of the first blind tapered hole 2 and the disc-shaped body 4 A first arc-shaped transition portion 41 is provided, and a second arc-shaped transition portion 42 is provided between the bottom of the second tapered blind hole 3 and the disc-shaped body 4. The forging body 1 includes a small head end with a first tapered blind hole 2...

The invention relates to a bearing outer ring forging for automobiles, solving the technical problem that the prior art is not reasonable enough in design. The forging comprises a forging body, a first tapered blind hole, a second tapered blind hole, a disc-like body, first arc-shaped transition parts, second arc-shaped transition parts, first tapered barrels, triangular discs, second tapered barrels, first cylindrical blind holes and second cylindrical blind holes, wherein first semi-spherical oil storage grooves are formed in the bottoms of the first cylindrical blind holes and are connected with first oil inlet channels; second semi-spherical oil storage grooves are formed in the bottoms of the second cylindrical blind holes and are connected with second oil inlet channels; the first oil inlet channels and the second oil inlet channels are distributed in a V shape and are communicated with oil inlets. The bearing outer ring forging for automobiles has the advantages that the bearing outer ring forging for automobiles has high precision, easily maintains the quality of finished products and has high strength; the finished outer rings have good lubricating properties after being assembled by reserving the oil storage grooves, so that steel balls roll smoothly.
Description
technical field [0001] The invention belongs to the technical field of auto parts, in particular to a forging of an outer ring of an automotive bearing. Background technique [0002] Bearings are one of the most widely used parts in mechanical engineering or automobiles. Most bearings mainly include outer rings, rolling elements, cages, and inner rings. The outer rings usually play a supporting role in the bearing housing or in the housing of mechanical components. The outer ring of the bearing is mostly processed by the outer ring forgings through precision turning, so the quality of the outer ring forgings determines the quality of the finished outer rings after processing to a certain extent, but the common outer ring forgings exist: low structural strength, Low precision, inconvenient subsequent processing, no reserved oil storage tank may easily lead to problems such as insufficient lubrication of the finished outer ring after assembly. When using this type of bearing,...
