At present; The load test method of tractor drive axle; Generally the drive axle output terminal is connected with the low speed end of cylinder gear speed reducer, the drive axle input end is connected with motor, utilizes the speedup of cylinder gear speed reducer reverse drive to be reached for the purpose of drive axle load.Such test method can't directly show load torque, can't carry out adjustable operation to load torque.
Summary of the invention
It is directly perceived, accurately that the purpose of the utility model just provides a kind of load data, uses simple, conveniently, can calculate the drive axle load test stand of drive axle transmission efficiency.
To achieve these goals; The utility model is provided with drive axle on the testing table pedestal; The drive axle input end connects with torque rotary speed sensor and variable-frequency motor through second shaft coupling and first shaft coupling; Torque rotary speed sensor is connected with tachometer torquemeter through lead, and frequency converter is connected with variable-frequency motor through lead, and drive axle two output terminals connect with torque sensor and magnetic powder brake through the 3rd shaft coupling and tetrad axial organ; Magnetic powder brake is connected with controller through lead, and torque sensor is connected with torductor through lead.
Through above setting, the input end of the utility model drive axle is regulated input torque through variable-frequency motor and frequency converter, and the indicating value of adjusting shows through torque rotary speed sensor and tachometer torquemeter; Output terminal is regulated the drive axle load torque through magnetic powder brake and controller; The indicating value of regulating shows through torque sensor and torductor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, variable-frequency motor 2, first shaft coupling 3, torque rotary speed sensor 4, second shaft coupling 5, drive axle 6, the 3rd shaft coupling 7, torque sensor 8, tetrad axial organ 9, magnetic powder brake 10, controller 11, torductor 12, frequency converter 13, tachometer torquemeter 14, testing table pedestal.
Embodiment
As shown in Figure 1; The utility model is provided with drive axle 5 on testing table pedestal 14; Drive axle 5 input ends connect with torque rotary speed sensor 3 and variable-frequency motor 1 through second shaft coupling 4 and first shaft coupling 2; Torque rotary speed sensor 3 is connected with tachometer torquemeter 13 through lead, and frequency converter 12 is connected with variable-frequency motor 12 through lead, and drive axle two output terminals connect with torque sensor 7 and magnetic powder brake 9 through the 3rd shaft coupling 6 and tetrad axial organ 8; Magnetic powder brake 9 is connected with controller 10 through lead, and torque sensor 7 is connected with torductor 11 through lead.Through above setting; The output torque of the variable-frequency motor 1 of the utility model is regulated control through frequency converter 12; Show that through torque rotary speed sensor 3 and tachometer torquemeter 13 magnetic powder brake 9 is realized electrodeless adjusting through the adjusting of controller size of current to braking moment.Braking moment is directly read through torque sensor 7, torductor 11.5 liang of output terminals of the direction of magnetic powder brake 9 braking moments and drive axle are exported the in the opposite direction of torque; It forms a locked-rotor torque, thereby the kinematic train of whole drive axle 5 has been increased a load through tetrad axial organ 8, torque sensor 7,6 pairs of drive axle 5 output shafts of the 3rd shaft coupling.The size of this load can be regulated through controller 10, through torductor 11 indicating values.Can calculate the transmission efficiency of drive axle through the input and the indicating value of output torque.
