Abstract

The utility model relates to a coupling structure between impeller and high-speed rotating shaft on high-speed centrifugal compressor which prevents the deformation of an impeller and a high-speed rotating shaft, and has the advantage of easy dismounting. The coupling structure between impeller and high-speed rotating shaft on high-speed centrifugal compressor comprises the high-speed rotating shaft and the impeller, and is characterized in that: a tensile axis penetrates throughout the central hole of the impeller; one end of the tensile axis is connected with an internal thread hole at the end part of the high-speed rotating shaft in a threading way; a compression nut is sleeved at the other end of the tensile axis; the end surface of the high-speed rotating shaft is fixedly connected with the extending shaft neck of the impeller; and the end surface at one end of the compression nut is fixedly connected with the end surface of the impeller.

Description

The impeller on a kind of high speed centrifugation compression device and the connecting structure of high speed rotating shaft
(1) technical field
The utility model relates to the compression device technical field, is specially the impeller on a kind of high speed centrifugation compression device and the connecting structure of high speed rotating shaft.
(2) background technique
Existing high speed centrifugation compression device comprises centrifugal compressor and centrifugal blower, and it adopts the hot jacket method to make impeller directly be assemblied in the end of high speed rotating shaft.This structure need select bigger magnitude of interference not get loose when the high speed rotating to guarantee impeller usually, impeller or high speed rotating shaft will be heated to assembling again after the higher temperature for this reason.The elevated temperature heat cover assembling of this big magnitude of interference design, make high speed rotating shaft, especially impeller has produced bigger distortion after assembling, wherein the distortion of impeller can reduce the aeroperformance of impeller, and the distortion of high speed rotating shaft is what for to the stability that can have influence on the rotor running, reload the circumferential location of Shi Yinwu and cause the dynamic equilibrium state of whole high speed rotor destroyed often behind this external impeller demolition.
(3) summary of the invention
At the problems referred to above, the utility model provides the impeller on a kind of high speed centrifugation compression device and the connecting structure of high speed rotating shaft, and it can guarantee that high-speed rotating shaft and impeller are indeformable, and its easy accessibility.
Its technological scheme is such: it comprises high speed rotating shaft, impeller, it is characterized in that: tensile axis runs through in the center hole of described impeller, described tensile axis threaded one end connects the interior threaded hole of described high speed rotating shaft end, gland nut is set in the other end of described tensile axis, described high speed rotating shaft end face is fastenedly connected the overhanging axle journal of described impeller, and the end face of described gland nut one end and the end face of described impeller are fastenedly connected;
It is further characterized in that: the protruding circular ring of described tensile axis one end partly press-fits in described center hole exterior projection branch, described high speed rotating shaft end face has endoporus, and the overhanging axle journal of described impeller is fastenedly connected the endoporus of described high speed rotating shaft end face by alignment pin; Described gland nut circumferential end has to dial changes the hole.
In the said structure of the present utility model, because tensile axis runs through in the center hole of described impeller, described tensile axis threaded one end connects described high speed rotating shaft, gland nut is set in the other end of described tensile axis, the end face of described gland nut one end and the end face of described impeller are fastenedly connected, described high speed rotating shaft end face is fastenedly connected the overhanging axle journal of described impeller, it no longer needs to carry out the hot jacket method and installs, so high-speed rotating shaft and impeller are indeformable, and then guarantee the aeroperformance of impeller, the stability of rotor running, and it is by being threaded its easy accessibility.
(4) description of drawings
Fig. 1 is the plan view schematic representation of connecting structure of the present utility model.
(5) embodiment
See Fig. 1, the utility model comprises high speed rotating shaft 1, impeller 2, tensile axis 3 runs through in the center hole 11 of impeller 2, the be threaded interior threaded hole 5 of high speed rotating shaft 1 end of tensile axis one end 4, gland nut 6 is set in the tensile axis the other end 7, high speed rotating shaft end face 8 is fastenedly connected the overhanging axle journal 9 of impeller 2, and the end face of gland nut 6 one ends and the end face of impeller 2 are fastenedly connected; The protruding circular ring part 10 of tensile axis one end 4 press-fits in center hole 11 exterior projection divides 12, and high speed rotating shaft end face 8 has endoporus, and the overhanging axle journal 9 of impeller 2 is fastenedly connected the endoporus of high speed rotating shaft end face 8 by alignment pin 13; Gland nut 6 circumferential end have to dial changes hole 14.
