Technical field
The utility model belongs to mechanics metrology and measurement equipment technical field, relates to the small and special electric machine reaction moment tester of a kind of output torque for measuring small and special electric machine and Mechanics of Machinery characteristic.
Background technology
Along with the develop rapidly of modern science and technology, the demand for small and special electric machine in the technical fields such as robot, mechanical arm, micromachine is increasing.And in the development, production run of small and special electric machine, be then indispensable to the output torque of small and special electric machine and the test of mechanical mechanics property thereof.Small and special electric machine reaction moment tester is exactly be specifically designed to measure the output torque of miniature specific type of electric machine and the gauging instrument of mechanical mechanics property thereof.
The output torque of the miniature specific type of electric machine of traditional measurement and the method for mechanical mechanics property thereof are the measuring methods adopting dynamometer machine, its step is by the shaft coupling connection coaxial with dynamometer machine input shaft by measured small and special electric machine shaft extension, certain electric current is passed to small and special electric machine, driving dynamometer machine rotates, hysteresis brake is provided with in dynamometer machine, hysteresis brake produces the moment of resistance and is used for the output torque of balance motor, regulate the electric current of hysteresis brake, the moment of resistance of hysteresis brake can be changed, under guarantee Rated motor operating voltage condition, motor runs with rated speed, so the moment recorded from dynamometer machine is rated moment, it is long-pending that rated power is now that rated speed is multiplied by rated moment.Dynamometer machine is measured output torque for general low-power machine and can be met the demands, but the not high defect of precision is just demonstrated for the small and special electric machine measuring several watts to tens watts, for micropower high-speed electric expreess locomotive, be even just with motionless dynamometer machine, reason is that the axle system moment of friction of dynamometer machine may be just large than motor output torque at all.
Utility model content
The purpose of this utility model is to solve prior art Problems existing, provide that a kind of structure is simple, principle is advanced, easy and simple to handle, measure efficiency and the high small and special electric machine reaction moment tester of precision.
For achieving the above object and adopt technical solution be such: the small and special electric machine reaction moment tester provided is by tested small and special electric machine frock, torgue measurement pallet, static-pressure air bearing, static-pressure air bearing seat, shaft coupling, torque sensor, torque sensor seat, flying wheel forms, the torque sensor be arranged on torque sensor seat is coaxially connected with the static-pressure air bearing be arranged on static-pressure air bearing seat by shaft coupling, torgue measurement pallet is arranged on the upper axle stretch end of static-pressure air bearing, tested small and special electric machine frock is arranged on torgue measurement tray center, torgue measurement pallet is provided with for filling the self-calibration arm bar hanging counterweight, flying wheel for being connected with tested small and special electric machine rotating spindle is arranged on the top of tested small and special electric machine frock.
Technical solution of the present utility model also comprises: on torgue measurement pallet, be provided with wire alligator forceps.
Small and special electric machine reaction moment tester described in the utility model have employed modern torque sensor technology, its measuring principle is: small and special electric machine seat is by static-pressure air bearing coupling torque sensor, the rotor axial system of small and special electric machine has certain moment of inertia J, small and special electric machine starts can produce certain angular acceleration Ω from the static rated speed that accelerates to, then small and special electric machine rated moment M is:
M＝J×Ω…………………………………………………(1)
M in formula (1) is small and special electric machine staring torque, and J is the rotor axial system moment of inertia of small and special electric machine, and Ω is the rotor axial system angular acceleration of small and special electric machine.
