Abstract
The utility model discloses an expansion sleeve type elastic pin test coupler which comprises a left coupler and a right coupler; wherein the right coupler is connected with the rotating shaft of a test device, and the left coupler is connected with a test motor rotating shaft. The expansion sleeve type elastic pin test coupler is characterized in that the left coupler is in interference connection with the motor rotating shaft for transmitting torsion; the left coupler consists of an expansion sleeve and an outer cylinder; the inner hole of the expansion sleeve comes into direct contact with the rotating shaft; the outer circle adopts a conic surface which comes into contact with the inner conic surface of the outer cylinder, and the expansion sleeve and the outer cylinder are connected at end surfaces by a bolt; a non-key coupling device realizes load transmission by tightening the high-intensity bolt to produce pressure and friction on the connection surface. The right coupler is connected with the test device by a key, and the torsion is transmitted by the key. In the expansion sleeve type elastic pin test coupler, the coupler is connected with the test motor rotating shaft by the expansion sleeve; therefore, the key connection defects are overcome.
Description
Technical field
The utility model relates to a kind of modular construction of motor component testing apparatus, is a kind of modular construction of testing apparatus of electric locomotive traction motor specifically, mainly is suitable for using as link in the test of electric locomotive traction motor.
Background technique
Locomotive traction motor all needs to carry out delivery test after making, its performance is carried out necessary detection.All be to move motor to laboratory during detection, on test stand, test that motor needs to dock just with testing apparatus and can test by coupling after being installed in test stand.Coupling is one and is installed on the testing apparatus that the other end is installed on the machine shaft to be tested; Drive the machine shaft rotation by coupling during the testing apparatus rotation, by test instrument the test motor is detected again.For the effect of proof test, when connecting test machine shaft and testing apparatus, must guarantee that machine shaft and experimental setup rotating shaft are on the same axis, otherwise will influence the normal operation of motor.But because motor is to be installed to test stand temporarily, so want to remain on same axis when docking with coupling is very difficult, especially present coupling is directly to connect with motor shaft by spline, so be difficult to aim at the axis of diaxon, to have to like this, it is little that the spline of joining shaft is frustrated, and makes things convenient for motor to insert in the coupling, but will make coupling and machine shaft form the gap like this, this will directly have influence on test effect, even can impact machine shaft.Therefore need further to be improved.
Summary of the invention
The purpose of this utility model, for the deficiency of the testing apparatus coupling that overcomes existing traction electric machine, it is more convenient to propose a kind of connection exactly, connect effective, and can be to the testing apparatus coupling of the hurtful traction electric machine of motor keyway.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of testing apparatus coupling of traction electric machine, coupling comprise Left-wing Federation's axial organ and two parts of right coupling; Wherein, the right coupling of coupling and the rotating shaft of testing apparatus are linked together, and Left-wing Federation's axial organ of coupling is linked together with the test machine shaft, and its characteristics are: Left-wing Federation's axial organ and machine shaft adopt Desing of Interference Joint, and come transmitting torque with this.Left-wing Federation's axial organ comprises expansion set and two parts of urceolus, the endoporus of expansion set directly contacts with rotating shaft, cylindrical then is to adopt conical surface, contact with the internal conical surface of urceolus with conical surface, then expansion set and urceolus are tied at end face, make the pressure and the frictional force that produce between female surface realize a kind of keyless joint device that load transmits by tightening high-strength bolt with bolt.Right coupling and testing apparatus adopt key joint, come transmitting torque by key.
The utility model links up coupling and machine shaft by expansion set, has avoided the defective that connects with key, to the concentricity requirement of test motor and testing apparatus, has improved the test effect when also having reduced simultaneously test, has lowered test labor intensity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, Left-wing Federation's axial organ; 2, right coupling; 3, the rotating shaft of testing apparatus; 4, test machine shaft; 5, expansion set; 6, urceolus; 7, end face; 8, bolt; 9, elasticity shaft joint; 10, spline.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the utility model is a kind of testing apparatus coupling of traction electric machine, and coupling comprises Left-wing Federation's axial organ 1 and 2 two parts of right coupling, and Left-wing Federation's axial organ 1 and right coupling 2 link together by elasticity shaft joint 9; Wherein, the right coupling 2 of coupling is linked together with the rotating shaft 3 of testing apparatus, and Left-wing Federation's axial organ 1 of coupling is linked together with test machine shaft 4, and its characteristics are: Left-wing Federation's axial organ 1 adopts Desing of Interference Joint with test machine shaft 4, comes transmitting torque with this.Left-wing Federation's axial organ 1 comprises expansion set 5 and 6 two parts of urceolus, the endoporus of expansion set 5 directly contacts with test machine shaft 4, the cylindrical of expansion set 5 then is to adopt conical surface, the conical surface of expansion set contacts with the internal conical surface of urceolus 6, on end face 7, there is bolt 8 that expansion set 5 and urceolus 6 are tied, makes the pressure and the frictional force that produce between female surface realize a kind of keyless joint device that load transmits by tightening high-strength bolt.Right coupling and testing apparatus connect by spline 10, come transmitting torque by key.
