Description
Technical Field
The utility model relates to a vehicle accessory technical field, concretely relates to improved generation high strength impeller for vehicle.
Background
The impeller is one of the common accessories in the vehicle, the connection of its impeller body of current impeller and impeller center pin divide into two kinds of dead connection and swing joint, the dead connection generally adopts the welded mode, this kind of mode is though joint strength between them is great, but be difficult to carry out convenient dismantlement, be unfavorable for the maintenance and the maintenance of impeller, swing joint utilizes connecting tool, for example bolt, bayonet lock etc. even this kind of mode is convenient for dismantle, but the general joint strength of current connected mode is lower, the impeller is in long-time use, radial or axial runout takes place easily for the impeller body, just lost the compactness between impeller body and the impeller center pin like this, lead to the rotatory unstability of impeller body, influence the result of use.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the improved high-strength impeller for the vehicle is provided, and the continuous connection strength of the impeller body and the central shaft of the impeller can be ensured.
The technical scheme is as follows: in order to realize the above-mentioned purpose, the utility model provides an improved generation high strength impeller for vehicle, including the impeller body and impeller center pin, the trailing end of impeller center pin is provided with gland nut, the fixed extension piece that is provided with on gland nut's the outside, the compact heap is being connected through the spring part to the extension piece, be provided with on the impeller body with compact heap assorted compressing groove, the compact heap cooperation is used for compressing tightly the impeller body compressing tightly at compressing tightly the inslot.
Furthermore, the butt joint ends of the impeller central shaft and the impeller body are respectively provided with a positioning groove and a positioning block which are matched with each other, the positioning groove and the positioning block not only can provide a positioning function in installation, but also can improve the connection strength of the impeller central shaft and the impeller body, so that the impeller central shaft can drive the impeller body to rotate better.
Furthermore, the constant head tank is ring groove structure and coaxial the seting up on the impeller center pin.
Furthermore, the compression nut is fixed on the central shaft of the impeller through the compression bolt, so that the stability of the compression nut on the central shaft of the impeller is improved.
Furthermore, a rubber layer is arranged on the contact surface of the pressing block and the impeller body, on one hand, the rubber layer can reduce friction between the pressing block and the impeller body and reduce loss caused by friction, and on the other hand, the rubber layer has a good elastic effect and can give a certain rebound thrust to the impeller body, so that the pressing effect on the impeller body is optimized.
Furthermore, a plurality of guide grooves and guide blocks which are matched with each other are respectively arranged on the compression groove and the compression block, and the guide grooves and the guide blocks are matched with each other, so that the guide function is provided, the compression block can be conveniently assembled and disassembled, the mutual position stability of the compression groove and the compression block is improved, the compression block has better stability, and the compression effect on the impeller body is ensured.
Has the advantages that: compared with the prior art, utilize gland nut, the extension piece, the compact heap, the spring part forms auxiliary connection mechanism with compressing tightly the groove, elastic action through the spring part, the compact heap can continuously give the impeller body and compress tightly bounce-back thrust, and because the restriction that compresses tightly the groove, the compact heap has possessed fine positional stability, make impeller body and impeller center pin can keep closely laminating, the continuous connection intensity at impeller body and impeller center has been guaranteed, prevent that the impeller body from taking place radially or the axial runout, the rotatory stability of impeller has been promoted, the result of use of impeller has effectively been ensured.
