Abstract
The utility model discloses a novel impeller with keys. The impeller is provided with a shaft hole; the surface of the shaft hole protrudes inwards along the axial direction and is provided with an integrally formed protruding key. Compared with that the surface of the shaft hole of the existing impeller is provided with a keyway, the novel impeller does not need to use single transmission key when assembling the impeller onto the shaft, saves the part and corresponding cost, has a simple assembly process for the impeller and the shaft, and only needs to push the protruding key onto the keyway on the shaft.
Description
Technical field
The utility model relates to a kind of novel impeller with key.
Background technique
Being in transmission connection all of the existing impeller of existing market and axle is provided with keyway and installs driving key and realize in keyway by corresponding on impeller and axle.This impeller is comparatively complicated with the linkage structure of axle, need process respectively axle, impeller and key during processing and fabricating, and workpiece is more, cost is bigger; Need during assembling earlier driving key to be packed into keyway on the impeller promotes impeller again and makes driving key enter keyway on the axle, and assembly process is comparatively complicated.Be not provided with the impeller of key in the market.
The model utility content
The purpose of this utility model is to provide a kind of novel impeller with key, and this impeller itself is provided with the key that is connected with shaft drive, and assembly process is comparatively easy when assembling with axle, and cost is lower.
For achieving the above object, inwardly protruding is one-body molded vertically on the axis hole surface of novel impeller with key of the present utility model is provided with protruding key.
Protruding key circumferentially evenly is provided with more than two along axis hole.
Impeller and protruding key material all are plastics or rubber.
The utlity model has following advantage:
1. inwardly protruding is one-body molded vertically on the axis hole surface is provided with protruding key, with offer keyway on the axis hole surface in the past and compare, when being assembled to impeller on the axle, need not use independent driving key, parts and corresponding cost have been saved, impeller is comparatively simple with the assembly process of axle simultaneously, and the keyway that only needs protruding key is pushed on the axle gets final product.
2. protruding key circumferentially evenly is provided with more than two along axis hole, can share moment of torsion by multikey when moment of torsion is big, thereby makes the utility model can bear bigger moment of torsion in use.
3. the material of impeller and protruding key is plastics or rubber, makes processing technology of the present utility model simpler.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, novel impeller with key of the present utility model includes impeller 1, and impeller 1 is provided with axis hole 2, and axis hole 2 surfaces inwardly protruding vertically are provided with protruding key 3, and protruding key 3 is formed in one with impeller 1.Wherein, the keyway on the shape of protruding key 3 size and the impeller wheel shaft is complementary; Protruding key 3 can be provided with one as shown in Figure 1, also can constitute spline structure along circumferentially evenly being provided with more than two of axis hole 2, and the number of certain protruding key 3 should be complementary with the keyway number on the wheel shaft; The material of impeller 1 and protruding key 3 can be plastics, also can be rubber, powder metallurgy or other material.
Claims (3)
1. novel impeller with key, impeller is provided with axis hole, it is characterized in that: inwardly protruding is one-body molded vertically on the axis hole surface of described impeller is provided with protruding key.
2. novel impeller with key according to claim 1 is characterized in that: described protruding key circumferentially evenly is provided with more than two along axis hole.
