Title:
VARIABLE SPEED-INCREASING GEAR AND CONTROL METHOD OF VARIABLE SPEED-INCREASING GEAR
Document Type and Number:
Japanese Patent JP2019148293
Kind Code:
A
Abstract:
To be able to operate effectively.SOLUTION: A variable speed-increasing gear comprises: a planetary gear transmission 10 for transmitting the rotary driving force transferred from an electric motor device 50 to the drive object via an output axis Ao by changing speed of the rotary driving force to a drive object; and a rotation control part 100 for adjusting the rotation speed of a variable speed rotor 72. The electric motor device 50 includes: a constant speed electric motor 51 having a constant speed rotor 52; a variable speed rotor 72; and a variable speed electric motor 71 driven in regenerative mode that functions as a generator and power running mode that functions as a motor. The output axis Ao has a variable rotation speed within an operating range between the maximum rotation speed and the minimum rotation speed. The constant speed electric motor 51 alone has a rated torque capable of setting the output axis Ao to the maximum rotational speed. The rotation control part 100 changes the rotation speed of the output axis Ao within the operation range by driving the variable speed motor 71 only in the regeneration mode.SELECTED DRAWING: Figure 1
