Abstract
The utility model discloses a novel hub, which comprises a conical sleeve, a middle disc and a shaft end blocking ring. The center of the conical sleeve is provided with a shaft hole, an outer ring of the conical sleeve is fixedly connected with the middle disc, the disc surface on the periphery of the middle disc is provided with a threaded hole fixed with a rear disc of an impeller, and the left end face of the middle disc is fixedly connected with the shaft end blocking ring. The novel hub has high reliability; the conical sleeve is connected with a taper of the middle disc so that the hub has high concentricity and anti-torque performance of the shaft head is improved; and by means of arrangement of a piece withdrawing hole and a cutting groove, the novel hub is convenient to install and dismount and can protect a shaft head of a motor well.
Description
Technical field
The utility model relates to a kind of wheel hub, is specifically related to a kind of novel hub.
Background technique
Be installed in the wheel hub on the motor shaft head during motor wheel hub, motor directly is connected with blower fan, and compact structure, and is cheap, is widely used in the blower fan industry, but also has shortcoming, because the motor shaft head size is less, the moment of torsion that the shaft head branch bears is less; And damage the motor spindle nose during wheel hub dismounting easily, the motor price general charged is higher; Nuclear safety shoulders heavy responsibilities, and the nuclear power station blower fan is for Security, and reliability requirement is very high, has certain defective in traditional motor wheel hub reliability, the dismounting, can not satisfy the high requirement such as dismounting, protection of wheel hub.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, a kind of novel hub to be provided.
Technological scheme: for achieving the above object; The utility model provides a kind of novel hub; Said wheel hub comprises tapered sleeve, mid-game and shaft end ring, and said tapered sleeve center is provided with axis hole, and said tapered sleeve outer ring is fixedly connected with mid-game; The card of said mid-game periphery is provided with and the fixing tapped hole of impeller hub disk, is fixedly connected with shaft end ring on the mid-game left end face.
What also be provided with mid-game for convenience detach on the said mid-game card moves back the part hole.
Said tapered sleeve and mid-game are connected through corresponding 1/6～1/10 tapering, and adopt socket head screw to fix, and the tapered sleeve outer ring is provided with and the suitable grooving of said mid-game.
Beneficial effect: the novel hub of the utility model, possess higher reliability, tapered sleeve is connected with the tapering of mid-game, makes wheel hub have higher concentricity, improves the torque resistant performance of spindle nose; Move back the setting of part hole and grooving, make things convenient for installing/dismounting, protect motor shaft head preferably.
