Embodiment 1

[0015] like figure 1 and figure 2 As shown in the present invention, in the overspeed experimental bench used for the rotor of the automobile driving motor, the end cover 101 of the motorized spindle 1 is connected to one end of the adapter sleeve 2 by screws, and the end cover 301 of the motor rotor 3 is connected by screws to the end of the rotating sleeve 2. At the other end of the adapter sleeve 2, the flange surface 201 of the adapter sleeve 2 is connected to the vertical wall 401 of the L-shaped plate 4 through screws, and the horizontal wall 402 of the L-shaped plate 4 is connected to the bench bottom plate 5 through screws. The rotating shaft 102 of 1 and the rotating shaft 302 of the motor rotor 3 transmit the rotational speed and torque through the elastic coupling 6. There is a protective baffle 7 above the elastic coupling 6 for protection. The electric spindle support frame 8 on the horizontal wall 402 of the L-shaped plate 4 and the motor rotor support frame 10...

Abstract

The invention relates to an excess speed experiment bench for an automobile driving motor rotor, which utilizes high-speed characteristics of a motorized spindle and controls the motorized spindle toprovide different rotating speeds through a frequency converter, thereby meeting speed requirements of a tested motor rotor in an excess speed and excess speed endurance experiment. The excess speed experiment bench meets temperature requirements of a tested motor rotor system in the excess speed and excess speed endurance experiment through controlling temperature changes of an environmental box.The excess speed experiment bench covers excess speed and excess speed endurance experiment conditions of most types of automobile driving motor rotors, solves the problems such as high cost and bench damages when conducting an excess speed experiment by using a twin trawling bench. The excess speed experiment bench is simple and compact in structure and low in cost.

Description

Technical field: [0001] The invention relates to the field of electricity, in particular to a technology for testing the strength of a rotor of a high-speed driving motor of an automobile, in particular to an overspeed experimental bench used for the rotor of the driving motor of an automobile. Background technique: [0002] New energy vehicles generally use electric drive systems. Its technology development trend is to pursue higher power density and higher efficiency. High-speed motor is an effective technical development direction. Mainstream electric vehicles generally choose high-speed drive motors to improve power performance. The high speed of the motor puts forward higher requirements on the mechanical strength and rigidity of the motor rotor. Therefore, the overspeed and overspeed endurance experiments of the motor rotor have become the final barrier to ensure the strength, stiffness and fatigue life of the rotor. At present, the price of the drag rig used for ov...
