Abstract
The utility model discloses the rotation of a kind of high-speed electric expreess locomotive and flexibly connects axle, is made up of dumbbell type male splined shaft, universal joint, connecting rod, screw, nut etc.Thick middle part, dumbbell type male splined shaft two ends is thin, and front end external splines connects with prime mover internal spline, and rear end external splines connects with motor hollow spindle internal spline.Dumbbell type male splined shaft forms protection time abnormal to system stall, short circuit etc.; Flexibly connect axle and motor internal hollow spindle forms flexible connected, easy replacing easy to maintenance; Splined makes connection uniform force, and centering is good.Technique effect of the present utility model is: (1) male splined shaft becomes dumbbell shaped, forms protection to during system exception; (2) axle is flexibly connected and motor internal main shaft forms flexible connected, easy replacing easy to maintenance; (3) splined uniform force, centering is good.
Description
Technical field
The utility model relates to a kind of motor shaft, is specifically related to the rotation of a kind of high-speed electric expreess locomotive and flexibly connects axle.
Background technique
When high-speed rotary motor runs, on the one hand, rotating speed is high, internal structure is complicated, compact, the centrifugal force that on rotor, each component bear is very large, and each component need reliable fixing, otherwise component loosen the generation easily causing security incident, therefore be designed to not Easy-dismounting structure, make the component of high-speed electric expreess locomotive inside be difficult to change maintenance like this.On the other hand, when system be short-circuited, the abnormal conditions such as stall time, need hard stop, avoid the external electronic component of inner member and whole system to damage.Therefore, need research one can protect system when there are abnormal conditions, and easily change the device safeguarded.
Summary of the invention
The purpose of this utility model is that providing a kind of high-speed electric expreess locomotive to rotate flexibly connects axle, and this coupling shaft uniform force, centering are good, can form protection, easily change maintenance, be particularly suitable for the working environment of High Rotation Speed after damage system.
The utility model is achieved in that a kind of high-speed electric expreess locomotive rotates and flexibly connects axle, forms primarily of dumbbell type male splined shaft, universal joint, pressing plate, connecting rod, screw, nut and generator hollow spindle, it is characterized in that: dumbbell type male splined shaft, universal joint, pressing plate, connecting rod is reliably linked into an integrated entity by screw, described dumbbell type male splined shaft is divided into front end external splines, splined shaft axostylus axostyle and rear end external splines three part, thick middle part, two ends is thin, front end external splines connects with prime mover, rear end external splines connects with motor hollow spindle, the described whole axle that flexibly connects penetrates generator hollow spindle, the rear end of dumbbell type male splined shaft is engaged with generator hollow spindle internal spline, connecting rod tail end nut is fixed on hollow spindle tail end, flexible connected is formed with motor internal hollow spindle, when flexibly connecting axle and fracture occurring, easy replacing easy to maintenance.
The utility model adopts spline joint axle, and splined makes connection uniform force, and centering is good; Splined shaft is dumbbell structure, and thick middle part, two is thin, and when system generation stall, short circuit etc. are abnormal, part thin in the middle part of splined shaft exceedes allowable stress due to stressed and rupture, thus disconnects generator and connecting between prime mover, plays a protective role to system; Splined shaft and electric machine main shaft are formed and flexibly connect, easy replacing easy to maintenance.
Technique effect of the present utility model is: adopt external splines to connect, make connection uniform force, centering good; Coupling shaft becomes dumbbell shaped, and two ends are thick, and middle part is thin, and ability to bear reduces, and forms protection to system short-circuit, stall time abnormal; Whole coupling shaft and motor hollow spindle form flexible connected, easy replacing easy to maintenance.
Accompanying drawing explanation
Fig. 1 is that high-speed electric expreess locomotive of the present utility model rotation flexibly connects axle construction schematic diagram.
Fig. 2 is dumbbell type male splined shaft structural representation of the present utility model.
Fig. 3 is that high-speed electric expreess locomotive of the present utility model rotation flexibly connects axle assembling schematic diagram.
In the drawings: 1, dumbbell type male splined shaft, 2, universal joint, 3, pressing plate, 4, connecting rod, 5, screw, 6, nut, 7, generator hollow spindle, 8, front end external splines, 9, splined shaft axostylus axostyle, 10, rear end external splines.
Embodiment
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.
As shown in Figure 1, a kind of high-speed electric expreess locomotive rotates and flexibly connects axle, this generator flexibly connects axle and adopts splined mode, makes connection uniform force, centering good, forms primarily of dumbbell type male splined shaft 1, universal joint 2, pressing plate 3, connecting rod 4, screw 5, nut 6; It is characterized in that: dumbbell type male splined shaft 1, universal joint 2, pressing plate 3, connecting rod 4 are reliably linked into an integrated entity by screw 5.Dumbbell type male splined shaft 1 is divided into front end external splines 8, splined shaft axostylus axostyle 9, rear end external splines 10 3 part; thick middle part, two ends is thin; front end external splines 8 connects with prime mover; rear end external splines 10 connects with motor hollow spindle 7; when system stall, short circuit etc. are abnormal; warping stress owing to being subject in the middle part of dumbbell type male splined shaft is greater than allowable stress and ruptures, thus disconnects connecting of generator and prime mover, plays a protective role to system.The whole axle that flexibly connects penetrates generator hollow spindle 7, the rear end of dumbbell type male splined shaft 1 is engaged with generator hollow spindle 7 internal spline, connecting rod 3 tail end is screw thread, generator hollow spindle 7 tail end is fixed on nut 5, flexible connected is formed with generator hollow spindle, when flexibly connecting axle and fracture occurring, easy replacing easy to maintenance.
