Detachable reinforced aluminum alloy impeller

Technical Field

The utility model relates to the field of vehicle accessory manufacturing, in particular to a detachable reinforced aluminum alloy impeller.

Background

The impeller is a commonly used accessory for vehicles, and mainly comprises an impeller body and an impeller shaft, the impeller body and the impeller shaft are welded to form the impeller in the conventional process, and the connecting mode has many defects, such as incapability of disassembly, inconvenience for independent maintenance or replacement of the impeller body and the impeller shaft, short service life of the whole impeller, difficulty in realizing accurate positioning of the installation position of the impeller body on the impeller shaft, and low installation accuracy due to the adoption of the welding mode.

In order to solve the problems, many assembled impellers are available on the market, and the assembling and fixing of the impeller body and the impeller shaft are realized through an auxiliary connecting structure, which solves the problems existing in the welding mode, but in the existing connecting structure, the connecting strength of the impeller body and the impeller shaft is not very high, especially the axial position is not very stable, and the impeller body is easy to generate axial deviation on the impeller shaft in the long-time use process of the impeller, so that the use effect of the impeller is affected.

Disclosure of Invention

The purpose of the utility model is as follows: in order to overcome the defects in the prior art, the detachable reinforced aluminum alloy impeller is provided, the connection strength of the impeller body and the impeller shaft can be improved, the impeller body is ensured not to generate axial deviation, and the continuous and stable use effect of the impeller is ensured.

The technical scheme is as follows: in order to achieve the purpose, the utility model provides a detachable reinforced aluminum alloy impeller which comprises an impeller body and an impeller shaft, wherein a positioning connecting ring matched with the impeller shaft is arranged on the back surface of the impeller body, a limiting protruding ring used for being in butt joint with the positioning connecting ring is arranged on the impeller shaft, a plurality of positioning screws are arranged on the limiting protruding ring, positioning screw holes matched with the positioning screws are formed in the positioning connecting ring, a tightening ring is arranged on the front surface of the impeller body on the impeller shaft, and the tightening ring is screwed on the impeller shaft and used for tightening and fixing the impeller body.

Furthermore, the number of the set screws is 8, and the set screws are symmetrically arranged on the limiting protruding ring, so that the connection effect is optimized and improved.

Further, the positioning connecting ring and the impeller body are integrally formed.

Furthermore, an annular groove is formed in the contact surface of the tightening ring and the impeller body, a rubber elastic ring is arranged in the annular groove, the rubber elastic ring can be kept tightly attached to the impeller body, continuous elastic force is provided for the impeller body, and therefore the axial position stability of the impeller body is further improved.

Further, the ring groove and the tightening ring are coaxially arranged.

Furthermore, the inner ring wall of the tightening ring adopts an internal thread structure, and the impeller shaft is provided with an external thread structure matched with the internal thread structure.

Has the advantages that: compared with the prior art, the utility model has the advantages that through the positioning connection effect of the positioning screws on the impeller shaft and the tightening effect of the tightening ring on the impeller shaft, the impeller body has good radial and axial connection strength on the impeller shaft, the impeller body is ensured not to generate axial deviation, and the continuous and stable use effect of the impeller is ensured.
