PROBLEM TO BE SOLVED: To provide a deceleration transmitting method which drives the rotary shaft of a device to be rotated at a minimum speed, invariably, stably, and with high rotating precision without using any fly-wheel. SOLUTION: In a deceleration transmitting method decelerating the rotation of a motor 1 to a minimum speed slower than 10 rotations per minute by a decelerator 3 to transmit to the rotary shaft 12 of the device to be moved 11, the decelerator 3 is made a traction driving system, the motor 1 is made a variable speed system, the rotary shaft 5 of the motor 1 is incorporated as the input element 8 of the decelerator the decelerator 3 and the rotary shaft 12 of the device to be moved 11 is connected directly with the output element 9 of the decelerator 3 to adjust the rotation speed of a rotary shaft of the motor 1 in order that the detected value of the rotation speed at the shaft 12 of the device 11 is always held to be a set value by feedback control. Therefore, rotation irregularity coused at the rotary shaft 12 of the device 11 by a transmitting error on working precision and assembling precision of a transmission system from the motor 1 to the device 11 and external diffusion including the fluctuation of a load at the device 11 is eliminated. |
