Abstract
A vane pump shaft comprises a pump shaft body, rubber pressure strips, an impeller and a nut. One end of the pump shaft body is provided with a five-petal mounting part; one end of the five-petal mounting part is provided with a threaded part. The center of the impeller is provided with an impeller connecting part; the center of the impeller connecting part is provided with a regular pentagonal mounting socket. Each two connected sides of the regular pentagonal mounting socket at the center of the impeller are connected through a curved surface; the curved surface of the regular pentagonal mounting socket in the center of the impeller connecting part at the center of the impeller is equal to the outline of the five-petal mounting part. The impeller is mounted on the five-petal mounting part of the pump shaft body through the impeller connecting part. The rubber pressure strips are mounted between the regular pentagonal mounting socket of the impeller connecting part and the sides of the five-petal mounting part. The nut is mounted on the threaded part at one end of the five-petal mounting part of the pump shaft body. The pump shaft mounting part is in a five-petal shape; the application of the symmetric structure ensures high work efficiency and rare damage; the rubber pressure strips are arranged between the mounting part and the mounting socket, so that noise can be reduced and wear of the pump shaft can be reduced.
Description
Technical field
The utility model relates to pump shaft field, particularly a kind of impeller shaft.
Background technique
Existing impeller shaft mostly clamps mode by key and installs, therefore after installing, very easily wear and tear, or damage, so greatly affected the working life of impeller shaft, and due to be use key clamp place install, therefore the middle meeting of working produces very large noise, if pump shaft is not that symmetric form pump shaft wheel rotation gets up greatly to affect pump shaft efficiency in addition.
Model utility content
For above problem, the utility model is a kind of impeller shaft, this pump shaft assembly department is five leaf, use this symplex structure assembly department working efficiency high, be difficult for being damaged, and between assembly department and mounting groove, there is a rubber press strip, can greatly reduce the wearing and tearing that noise reduces pump shaft, for reaching this object, the utility model provides a kind of impeller shaft, comprise pump shaft main body, rubber press strip, impeller and nut, described pump shaft main body one end is five leaf assembly departments, described five leaf assembly department one end are screw section, there is impeller joint at described impeller center, there is regular pentagon mounting groove at described impeller joint center, two connected sides of regular pentagon mounting groove, described impeller center are connected by curved surface, the curved surface of the regular pentagon mounting groove at described impeller center impeller joint center is identical with the external frame of five leaf assembly department blade profiles, described impeller is arranged on the leaf assembly department of pump shaft main body five by impeller joint, between described impeller joint regular pentagon mounting groove and five leaf assembly department sides, rubber press strip is installed, there is screw section the leaf assembly department of described pump shaft main body five one end, described nut is arranged on screw section.
As further improvement of the utility model, described rubber press strip length is less than five leaf assembly department height 0.5cm, in order to prevent that press strip from exerting an influence to wheel rotation, therefore needs to use shorter rubber press strip.
The utility model is a kind of impeller shaft, this pump shaft impeller is installed on five leaf assembly departments, because assembly department adopts five leaf structures, therefore more stable when vane rotary, the working efficiency of impeller is higher, and owing to there being rubber press strip between assembly department and mounting groove, owing to using rubber press strip, can greatly reduce on the one hand the wearing and tearing of pump shaft, rubber press strip can greatly reduce the noise in work on the other hand.

Embodiment
Below in conjunction with drawings and Examples, model utility is described in detail:
The utility model is a kind of impeller shaft, and this pump shaft assembly department is five leaf, uses this symplex structure assembly department working efficiency high, is difficult for being damaged, and has rubber press strip between assembly department and mounting groove, can greatly reduce noise and reduce the wearing and tearing of pump shaft.
As a kind of embodiment of the utility model, the utility model provides decomposing schematic representation a kind of impeller shaft as shown in Figure 1, comprise pump shaft main body 1, rubber press strip 4, impeller 5 and nut 6, described pump shaft main body 1 as shown in Figure 3 one end is five leaf assembly departments 2, described five leaf assembly department 2 one end are screw section 3, described impeller 5 as shown in Figure 2 center has impeller joint 5-1, there is regular pentagon mounting groove 5-2 at described impeller joint 5-1 center, described impeller 5 two connected sides of regular pentagon mounting groove 5-2, center are connected by curved surface, the curved surface of the regular pentagon mounting groove 5-2 at described impeller 5 center impeller joint 5-1 centers is identical with the external frame of five leaf assembly department 2 blade profiles, described impeller 5 is arranged on the leaf assembly department 2 of pump shaft main body 1 five by impeller joint 5-1, between described impeller joint 5-1 regular pentagon mounting groove 5-2 and five leaf assembly department 2 sides, rubber press strip 4 is as shown in Figure 4 installed, described rubber press strip 4 length are less than five leaf assembly department 2 height 0.5cm, in order to prevent that press strip from rotating and exerting an influence impeller 5, therefore need to use shorter rubber press strip 4, there is screw section 3 the leaf assembly department of described pump shaft main body 1 five 2 one end, described nut 6 is arranged on screw section 3.
The above; it is only preferred embodiment of the present utility model; be not the restriction of the utility model being made to any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
