Load device can be single cover, be arranged on the center line of base plate, also can be two covers, with the center line is that the center is symmetrically distributed, as preferably, described load simulating device has two covers, is that the center is symmetrically distributed with the center line on base plate, two friction pulleys of two covers on the load simulating devices are socketed on the transmission shaft on the same gear frame, and gear frame is arranged between the two cover load simulating devices.Described center line is along motor and load arrangements direction.Gear frame is arranged on the center line, near two cover load simulating devices, is fixed with transmission shaft on the gear frame, transmission shaft with treat that the output shaft of measured motor is synchronized with the movement, transmission shaft drives friction wheel from rotation, the friction force between friction pulley and the friction disc is the load of motor.Two cover load symmetric arrangement can be so that stress equalization, and convenient calculating.
Interlock between transmission shaft and the motor output shaft can adopt multiple mode, link as hinging manner, the belt mode links or the like, as preferably, the excircle of described transmission shaft is provided with a sprocket wheel, an end for the treatment of the output shaft of measured motor is provided with another sprocket wheel, and going up solderless wrapped connection between above-mentioned two sprocket wheels has hinge.
As preferably, described friction disc is an arc surface, and its radian is identical with the radian of the external peripheral surface of friction pulley, and friction disc is the canvas flat belt.Adopt the canvas flat belt, the heat of generation is few, can prolong the serviceable life of friction disc.
Therefore, the utlity model has following advantage: 1, the friction force between employing friction disc and the friction pulley is as motor load, and simple in structure, convenience is debugged; 2, the rotating speed of motor output shaft is identical with the friction pulley rotating speed, is convenient for measuring data, and simulation mechanism can be measured the data of multiple class, and versatility is good; 3, adopt compression spring and compression pull bar to constitute hold-down mechanism, make things convenient for regulating load, can well friction pulley closely be abutted against with friction disc simultaneously; 4, friction disc is fixed on the fixed block, is convenient for changing, easy to use, cost is low; 5, friction disc adopts the canvas flat belt, and it is few to produce heat, prolongs mechanism serviceable life.
