The advantages that honest and clean, space-consuming small volume.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention includes being fixed on motor 3,1# gearboxes 5, support base 8, the torque sensor of installation flat board 2 upper end
9th, 2# speed changers 10, magnetic powder brake 11, as shown in figure 1, installation flat board 2 lower end is provided with Damping cushion 1, the driving electricity
One end of machine 3 is connected through flexible sheet shaft coupling 4 with one end of 1# gearboxes 5, and the other end of 1# gearboxes 5 is through sleeve 7 and quilt
One end connection of axle 6 is surveyed, the other end of measured axis 6 is connected through flexible sheet shaft coupling 4 with one end of support base 8, support base 8
The other end is connected through flexible sheet shaft coupling 4 with one end of torque sensor 9, and the other end of torque sensor 9 is through flexible sheet
Shaft coupling 4 is connected with one end of 2# speed changers 10, and the other end of 2# speed changers 10 is through flexible sheet shaft coupling 4 and magnetic powder brake
11 connections.
It is described installation flat board 2 respectively with motor 3,1# gearboxes 5, support base 8, torque sensor 9,2# speed changers
10th, adjustment cushion block 12 is equipped between magnetic powder brake 11.
The invention discloses a kind of dynamic torque table apparatus, can apply the torque value of dynamic change to measured axis, wrap
Include opplied moment application system, load brake system and torch measuring system.Motor 3, the 1# of described application torque become
Fast case 5, flexible sheet shaft coupling 4, measured axis 6 and sleeve 7 are opplied moment application system；Described magnetic powder brake 11,2#
Gearbox 10 and flexible sheet shaft coupling 4 are load brake system；8, two described torque sensor 9, support base elastic membranes
Piece shaft coupling 4 and sleeve 7 are torch measuring system.
Wherein 1# gearboxes 5 and 2# gearboxes 10 can high, medium and low three class gear shifts.During work, when device is operated in low torsion
Square trystate, motor 3 export nominal torque and rated speed, and the torque value that now motor 3 exports is low, rotating speed
Height, during according to actual speed state, 1# gearboxes 5 are placed in or high tap position, the opplied moment that motor 3 exports pass through diaphragm
Shaft coupling 4 is transferred to the input shaft of 1# gearboxes 5, and measured axis 6 is transferred directly to by sleeve 7 by the output shaft of 1# gearboxes 5
Right-hand member, measured axis 6 is now in low torque, high measurement of rotating speed state, then is passed by the left end of measured axis 6 through sleeve 7 and support base 8
The right-hand member of torque sensor 9 is handed to, drives sensor 9 to rotate, then be transferred to the input of 2# gearboxes 10
Axle, now need the gear of 2# gearboxes 10 being placed in low-grade location, reduce rotating speed, to protect magnetic powder brake 11, ensure magnetic

The programmable power supply electric current of dynamic device 11, thus it is possible to vary the load brake torque of magnetic powder brake 11, it is dynamic so as to be produced in connecting shaft section
State moment of torsion, the torque value exported in torque sensor real-time display connecting shaft section.
When device is operated in high torque trystate, the output of motor 3 is still nominal torque and rated speed, is now driven
Dynamic motor 3 still exports low torque, high rotating speed, but 1# gearboxes 5 and is placed on low-grade location, the opplied moment that motor 3 exports
The input shaft of 1# gearboxes 5 is transferred to by diaphragm coupling 4, after 1# gearboxes 5 slow down, increase moment of torsion, by 1# gearboxes 5
Output shaft the right-hand member of measured axis 6 is transferred directly to by sleeve 7, measured axis 6 will be in high torque, slow-speed of revolution test mode,
It is transferred to the right-hand member of torque sensor 9 through sleeve 7 and support base 8 by the left end of measured axis 6 again, drives sensor 9 to rotate, then transmit
To the input shaft of 2# gearboxes 10, during now the gear of 2# gearboxes 10 can be placed according to actual speed state or high tap position（Cause
Low speed state is in for now connecting shaft section, rotating speed is less than the rated value of magnetic powder brake 11, it is not necessary to slows down again with to magnetic
Brake 11 carries out Additional Protection）, then by the output shaft of 2# gearboxes 10 opplied moment is transferred to the defeated of magnetic powder brake 11
Enter on axle, drive magnetic powder brake 11 to rotate in same direction, produce reverse load brake torque, magnetic powder brake is inputted by adjusting
11 programmable power supply electric current, change the load brake torque of magnetic powder brake 11, so as to produce dynamic torque in connecting shaft section, turn round
The torque value exported in square sensor real-time display connecting shaft section.
