Abstract

The invention discloses an impeller base, which comprises a shaft (1) and an impeller support (2), wherein the impeller support (2) is welded on the shaft (1). The impeller base is characterized in that: a stabilizing hole (3) is formed in the shaft (1); and a stabilizing bolt (4) is arranged on the stabilizing hole (3). The impeller base disclosed by the invention cannot be loosened with a transmission shaft, and cannot bring loss to a user.

Description

A kind of impeller base

Technical field

The present invention relates to the impeller field, especially a kind of impeller base.

Background technique

Centrifugal pump, mixed flow pump, the stirrer that uses at present all adopts singly-bound locking; When medium and key contacts; The surface of key can receive burn into and wash away very easily damage, can generation become flexible between impeller base and the transmission shaft thereby lock unreliable causing, and brings bigger economic loss to the user like this.

Summary of the invention

In order to overcome the deficiency of existing technology, the present invention provides a kind of impeller base, reliable lock, it not can and transmission shaft between produce looseningly, can not bring loss for the user

Its technological scheme of the present invention's solution is in order to achieve the above object: a kind of impeller base, comprise axle and impeller support, and the impeller support is welded on the axis hole, and a stable hole is arranged on axle.

According to embodiments of the invention, have one to stablize bolt on the said stable hole.

According to embodiments of the invention, on the said stable bolt nut is arranged.

The invention has the beneficial effects as follows: it not can and transmission shaft between produce looseningly, can not bring loss for the user.

Description of drawings

The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is sectional view of the present invention;

Reference character is: 1 is axle, and 2 is the impeller support, and 3 is stable hole, and 4 is bolt, and 5 is nut.

Embodiment

Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.

Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.

By a kind of impeller base shown in Figure 1, comprise axis hole 1 and impeller support 2, impeller support 2 is welded on the axis hole 1, and a stable hole 3 is arranged on axis hole 1, has one to stablize bolt 4 on the stable hole 3, and a nut 5 is arranged on the forward bolt.In concrete practicality, tight a bolt earlier, at the counter-tightened nut, so not can and transmission shaft between produce looseningly, can not bring loss for the user.

The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.

Claims (3)

1. an impeller base comprises axle (1) and impeller support (2), and impeller support (2) is welded on the axle (1), it is characterized in that: a stable hole (3) is arranged on axle (1).

2. a kind of impeller base according to claim 1 is characterized in that: have one to stablize bolt (4) on the stable hole (3).

3. a kind of impeller base according to claim 2 is characterized in that: stablizing has a nut (5) on the bolt (4).
