CPC G01M 13/027 (2013.01) | 9 Claims |
1. A three-dimensional force loading device for a motor spindle, the device comprising:
a bottom plate;
a torque loading assembly configured for testing torque performance of the motor spindle, wherein the torque loading assembly and the motor spindle are both arranged on the bottom plate, and the torque loading assembly is in transmission connection with the motor spindle;
a sleeve shell rotatably sleeved on the motor spindle, wherein the sleeve shell is fixed along an axis direction of the motor spindle;
a radial force loading assembly configured for testing radial force performance of the motor spindle, wherein the radial force loading assembly is arranged on the bottom plate and configured for providing a radial loading force perpendicular to the axis direction of the motor spindle, and the radial force loading assembly is fixedly connected with the sleeve shell;
an axial force loading assembly configured for testing axial force performance of the motor spindle, wherein the axial force loading assembly is arranged on the bottom plate and configured for providing an axial loading force along the axis direction of the motor spindle; and
a intermediate force transmission mechanism connected with the sleeve shell and the axial force loading assembly to transmit the axial loading force supplied by the axial force loading assembly to the sleeve shell.
