Existing active motor shaft connects by coupling usually with tested motor shaft, it is fastening or by the key transmission that links that jackscrew must be installed simultaneously, yet need be by instrument when fastening by jackscrew, find the fixed position accurately and could realize, installation and take-down time are long, and jackscrew causes tested motor shaft damage easily.Simultaneously when being arranged on keyway on the described coupling and connecting, it is consuming time long that tested motor shaft is aimed at the process that keyway packs into, and can't test the optical axis motor of identical journal size.
In addition, the coaxality of common coupling during to the testing apparatus manufacturing had relatively high expectations, thereby increased the manufacture cost of whole testing apparatus, increases mounting complexity simultaneously greatly.
The model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and provide a kind of and do not rely on the fastening and key connecting transmission of jackscrew, but the alternating current servomotor back-emf test axle fast hitch mechanism of quick mounting, the tested motor of dismounting.
The purpose of this utility model solves by the following technical programs:
The utility model provides an a kind of alternating current servomotor back-emf test axle fast hitch mechanism, comprise that axle sleeve, elastic coupling flexible coupling reach the locking nut of the output shaft that is used for the described axle sleeve of locking and tested motor, described axle sleeve one end is provided with the axle fixed hole of the output shaft that can insert tested motor, one end of the projecting shaft of the described axle sleeve the other end and elastic coupling flexible coupling links, middle double-screw bolt and the locking nut of described axle sleeve link, and the other end of described elastic coupling flexible coupling is fixedlyed connected with the output shaft of active motor.
Described axle sleeve is the teflon axle sleeve; Described locking nut is the teflon nut.
Described axle sleeve one end is that outer side surface is the cone structure of the conical surface, described cone structure and described axle fixed hole are located at the same end of described axle sleeve, described axle fixed hole axial direction sidewall has stria, the conical surface of the inboard of described locking nut one end for matching with described cone structure, the inwall of the described locking nut the other end is provided with internal thread, and described locking nut outer surface rolls reticulate pattern.
Described elastic coupling flexible coupling is fixedly connected by clamping screw with the output shaft of active motor.
Described axle sleeve and elastic coupling flexible coupling are fixedly connected by clamping screw.
The utlity model has following beneficial effect:
Alternating current servomotor back-emf test described in the utility model is inserted in the axle fixed hole of described axle sleeve one end with the output shaft of axle fast hitch mechanism by tested motor, and by described locking nut axle sleeve and tested motor output shaft are fixedly connected, simultaneously the projecting shaft of described axle sleeve and an end of elastic coupling flexible coupling are linked, the other end of described elastic coupling flexible coupling is fixedly connected with the output shaft of active motor, thereby can avoid using jackscrew and keyway, when test, only need the output shaft of tested motor is inserted in the described axle fixed hole, and get final product by locking nut is fastening, convenient, simply, effectively save the installation time.Coupling adopts elastic coupling flexible coupling in addition, when the output shaft that can effectively compensate tested motor is installed radially, angle and axial deviation, greatly reduce testing apparatus manufacturing cost, guaranteed the reliability of installing.
