Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as Figure 1-2 As shown, the high-strength forging for the outer ring of the automobile wheel includes a forging body 1, one end of the forging body 1 is provided with a first tapered blind hole 2 that is narrow inside and wide outside, and the other end is provided with a second tapered hole 2 that is narrow inside and wide outside. Shaped blind hole 3, the first tapered blind hole 2 and the second tapered blind hole 3 are symmetrically arranged so that a disc-shaped body 4 is provided between the first tapered blind hole 2 and the second tapered blind hole 3, and the forging The body 1 includes a first conical cylinder 11 with a first tapered blind hole 2 at the small end, and a large end of the first conical cylinder 11 is connected with a mounting ring 12 positioned on the outer side of the disc-shaped body 4. The moun...

The invention relates to a high-strength automobile hub outer ring forge piece, solving the technical problems that the design in not reasonable enough, and the like in the prior art. The high-strength automobile hub outer ring forge piece comprises a forge piece body, a first cone-shaped blind hole, a second cone-shaped blind hole, a disc-shaped body, a first cone cylinder, a mounting ring body, a fixed seat body, an arc-shaped attached lug body and a second one cylinder, wherein the diameter from one end, connected with the fixed seat body, of the second cone cylinder to the other end gradually decreases; two oil injection holes which run through the mounting ring body along the radial direction are symmetrically formed in the mounting ring body; a first lubrication hole and a second lubrication hole which are respectively communicated with the oil injection holes are formed between the two oil injection holes, run through the whole disc-shaped body, are communicated with each other in a crossed manner and intersect at the center of the disc-shaped body. The high-strength automobile hub outer ring forge piece has the advantages that the design is relatively reasonable, the precision is high, the quality of finished products is easily maintained, and the strength is high; oil grooves are preformed in the machined products, so that the lubrication degree is high.
Description
technical field [0001] The invention belongs to the technical field of auto parts, in particular to a high-strength forging for the outer ring of an auto wheel hub. Background technique [0002] Bearings are one of the most widely used components in mechanical engineering or automobiles. For example, bearings used in automobile hubs generally include outer rings, rolling elements, cages, and inner rings. The outer rings are usually in the bearing housing or in the housing of mechanical components. It plays a supporting role. The common bearing outer ring is mostly made of outer ring forgings through precision turning, so the quality of the outer ring forgings determines the quality of the finished outer ring to a certain extent, but there are common outer ring forgings. : Low structural strength, low precision, inconvenient follow-up processing, and the processed products have problems such as easy wear. In addition, the existing outer ring forgings have the same problem of ...
