Rotating speed maintains a motor output rotating speed constant alternatively, reducing motor two by controller two exports rotating speed, same with this
When, another motor output rotating speed is reduced, while reducing the output power of the motor, makes motor one, motor
The difference of two rotating speeds improves the high rotating speed required to control by the slow-speed of revolution, and the difference of the rotating speed acts on twin shaft input planet gear differential
In retarder, it is made to export the small torque power driving constant power load device of high rotating speed.
When the deceleration system stops, the deceleration system is transported in constant power load operational mode one or constant power load
In the state of row pattern two, that high motor output rotating speed of rotating speed is reduced by controller one or controller two, is made electronic
Machine one, two rotating speed of motor difference be zero, then reduce motor one simultaneously, motor two exports rotating speed to zero, the reduction train
It unites out of service.
In the deceleration system operational process, twin shaft input planet gear differential speed reducer exports rotating speed and two motor
Speed discrepancy it is related, two motor can be in high-speed cruising state always, in the shape that two motor direction of rotation are constant
Under state, the direction of rotation of twin shaft input planet gear differential speed reducer can be changed, load device realization is driven frequently to accelerate,
Slow down, it is frequent to start, stop, even frequently changing the function of load device direction of rotation.The deceleration system can
Ensure that motor is run under the higher working condition of efficiency, and changes in twin shaft input planet gear differential speed reducer and load
Response speed is improved when device direction of rotation.The output rotating speed of the deceleration system is related to the speed discrepancy of two motor, then
Twin shaft input planet gear differential speed reducer has the advantages that transmission ratio is big, output torque is big, and the deceleration system is without flexibility
Gear, then twin shaft input planet gear differential speed reducer have the advantages that reliable for operation, service life is long, output torque is big.Institute
