Abstract
The utility model relates to an improved torque and rotating speed measurement device. The improved torque and rotating speed measurement device is characterized in that a torque measurement system is composed of a magnetic powder brake, a swing rod, a heavy hammer, torque, a dial, an indicating needle and an aluminum round disk which are fixed on the outer shell of the magnetic powder brake, a direct current electromagnet, adjustable type stable flowing current, etc. The improved torque and rotating speed measurement device can conveniently, stably, and visually measure the torque and the rotating speed of a small type motor. The price of the improved torque and rotating speed measurement device is only of 30% of the price of a similar product.
Description
The present invention is a kind of improved tachometer torquemeter, can measure the rotating speed and the torque of miniature motor convenient, intuitively.
The tachometer torquemeter of existing employing magnetic powder brake is turned round the shaft type torque sensor by elasticity and is cooperated digital instrument, measures and reading, and complex structure, about ten thousand yuan every of prices are restricted range of application.
The purpose of this invention is to provide a kind of simple in structure, stable reading, easy to use, satisfy that the miniature motor conventional sense requires, price only is the magnetic powder brake formula tachometer torquemeter of existing product 30% fully.
Task of the present invention is finished as follows:
Fig. 1 is the main structure chart of measuring instrument.
Fig. 2 is the axial cut-open view of magnetic powder brake.(the Lower Half symmetric part is not drawn).
Such as Fig. 1, tachometer generator 1, magnetic powder brake 4, tested motor 6 are assembled on the chassis overhang 7 by main shaft 10 connections, speed measuring system is drawn lead by tachometer generator 1 and is connected to (not shown in FIG.) on the ordinary rotational speed gauge outfit, when tested motor 6 drives main shaft 10 rotation by shaft coupling 5, can from revolution counter, directly read motor speed. Torque measurement system is major part of the present invention, it is made up of following several respects, magnetic powder brake 4 and the pointer 3 that is separately fixed at its shell both sides and aluminium matter (or copper) garden dish 13, fork 11, weight 12, torque dial 2, the identical adjustable constant-current source (not shown in FIG.) of two groups of circuit of magnet exciting coil in the DC electromagnet 14 that also has respectively power supply to give to be fixed on the chassis and the brake 4. The shell of brake 4 is bearing on the main shaft 10 by bearing 8, and main shaft 10 is bearing on the support 7 by bearing 9, and the operation principle of magnetic powder brake 4 such as Fig. 2, rotor 17 are fixed on the main shaft 10, and magnet exciting coil 15 is contained in the brake shell. Magnetic 16 is arranged in the cavity between shell and the rotor; In tested driven by motor main shaft 10 rotations, powered to magnet exciting coil 15 by adjustable constant-current source, produce magnetic flux 18, just produce interaction force between rotor 17 and the brake shell, also just produced the braking moment to rotor; Brake shell deflection under the moment loading of rotor, be connected with fork 11 and the weight 12 of proofreading and correct through moment because of shell, when treating that two moments equate, scale value on the indicated torque dial 2 of pointer 3 is the numerical value of motor output torque, change the input current value of magnet exciting coil 15, can measure easily the size of tested motor output torque. Aluminium matter or copper garden dish 13 and DC electromagnet 14 and power supply thereof form induction damper, when the torque measurement reading, drive pointers 3 rocking when the equilbrium position with limit stop 4, be convenient to reading, the rotational angle of brake 4 shells is from 0 °～90 °, and the weight free suspension is below brake 4 in the time of 0 °, moment is zero, moment maximum in the time of 90 °, the design's instrument torque range is 0-40 ox rice, 3.0 grades of certainties of measurement. Two groups of external constant-current sources that offer magnetic powder brake 4, DC electromagnet 14 can be with commercially available WLy-104 type, and it is continuously adjustable that DC current output is 0-1000mA.
When measuring, tested motor is loaded on the support 7, and are connected with main shaft closely by shaft coupling 5 and connect, connect earlier by measured motor 6 power supplys and DC electromagnet 14 power supplys, give again magnet exciting coil 15 energisings, continuously change constant-current source output, just can directly read by torque dial 2 torque value of motor. And read tachometer value being connected the revolution counter that connects with tachometer generator, namely finish measurement.
