11 connections.
It is described installation tablet 2 respectively with driving 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 utility model discloses a kind of dynamic torque table apparatus, can apply the torque of dynamic change to measured axis
Value, including opplied moment application system, load brake system and torch measuring system.The driving motor 3 of the application torque,
1# gearboxes 5, flexible sheet shaft coupling 4, measured axis 6 and sleeve 7 are opplied moment application system；The magnetic powder brake
11st, 2# gearboxes 10 and flexible sheet shaft coupling 4 are load brake system；8, two torque sensor 9, support base bullets
Property diaphragm coupling 4 and sleeve 7 be 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, driving motor 3 export nominal torque and rated speed, and the torque value that driving motor 3 exports at this time 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 driving 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 end, measured axis 6 is now in low torque, high measurement of rotating speed state, then is passed by 6 left end of measured axis through sleeve 7 and support base 8
The right end of torque sensor 9 is handed to, sensor 9 is driven to rotate, then be transferred to the input of 2# gearboxes 10
Axis needs 10 gear of 2# gearboxes being placed in low-grade location, reduces rotating speed at this time, to protect magnetic powder brake 11, ensures
The rotating speed of magnetic powder brake 11 is less than its rated value, then opplied moment is transferred to magnetic powders brake by the output shaft of 2# gearboxes 10
On the input shaft of device 11, magnetic powder brake 11 is driven to rotate in same direction, generates reversed load brake torque, magnetic is inputted by adjusting
The programmable power supply electric current of powder brake 11, thus it is possible to vary the load brake torque of magnetic powder brake 11, so as to be produced in connecting shaft section
Give birth to dynamic torque, the torque value exported in torque sensor real-time display connecting shaft section.
When device is operated in high torque trystate, the output of driving motor 3 is still nominal torque and rated speed, is driven at this time
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 driving motor 3 exports
The input shaft of 1# gearboxes 5 is transferred to by diaphragm coupling 4, after 1# gearboxes 5 slow down, increase torque, by 1# gearboxes 5
Output shaft the right end 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 end of torque sensor 9 through sleeve 7 and support base 8 by 6 left end of measured axis again, sensor 9 is driven to rotate, then transmit
To the input shaft of 2# gearboxes 10, during at this time 10 gear of 2# gearboxes can be placed according to actual speed state or high tap position（Cause
Low speed state is in for connecting shaft section at this time, rotating speed is less than the rated value of magnetic powder brake 11, does not need to slow down again with to magnetic powder
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 axis, magnetic powder brake 11 is driven to rotate in same direction, generates reversed load brake torque, magnetic powder brake is inputted by adjusting
11 programmable power supply electric current changes the load brake torque of magnetic powder brake 11, so as to generate dynamic torque in connecting shaft section, turns round
The torque value exported in square sensor real-time display connecting shaft section.
