Abstract
A rotary shaft transmission structure, which is designed with a simplified structure to provide a smooth and stable transmission of a rotary shaft and to reduce the occurrence of rotational torsion variation of the rotary shaft, includes a combination of at least one rotor and a traction portion. The rotor includes a shaft hole and a bolt bore, in which the shaft hole is utilized to pivot the rotary shaft so that the rotor can be rotated by the rotary shaft, the shaft hole transversely passed through by at least a plan area is utilized to retain the traction portion, and the rotary shaft is utilized to press the traction portion via the plan area, thereby forming a fixation function.

A rotary shaft transmission structure which is a combination of at least one rotor and a traction portion, the rotor comprising:
- a body providing a shaft hole utilized to fixedly connect a rotary shaft and a bolt bore, the traction portion formed as a flexible cable pattern to be windingly arranged on the body and comprising a first end and a second end, and at least one of the first end and the second end of the traction portion being passed through the bolt bore of the body to be fixed on the body;
- wherein when the traction portion is threaded through the bolt bore, at least one of the first end or the second end of the traction portion is coupled to a fixation portion, the fixation portion defines a hole formed therethrough for inserting the traction portion, and the fixation portion and the traction portion are integrally formed by pressing;
- wherein the body of the rotor is formed with a recessed room communicated with the bolt bore to receive the fixation portion, the recessed room including an outer wall surface, and the fixation portion further comprises an outer face surface corresponding to the outer wall surface of the recessed room.
