The present invention discloses a driving system for a belt axis of a winch in the field of mechanics, which addresses the problems existing in conventional driving systems, such as a complicated structure and poor reliability. The driving system for the belt axis of the winch is positioned at the extension end of the belt axis on one side of a winch support. The driving system includes a rotary body and a fixed base, in which the fixed base is connected to the extension end of the belt axis via a connection means and the inner end of the rotary body is set on the fixed base. An insertion pore is positioned at the outer end of the rotary body. A spring is provided between the rotary body and the fixed base, under the action of which the inner end face of the rotary body is attached to the outer end face of the fixed base. A one-way clutch mechanism is disposed between the inner end face of the rotary body and the outer end face of the fixed base, which is formed by engagement of the one-way gear teeth on the surfaces. The rotary body could drive the fixed base to rotate therewith only when it runs in one direction by way of the one-way clutch mechanism. Therefore, the present invention has benefits such as improved reliability and convenient installation and maintenance.
