This utility model discloses a vehicle-mounted electric well-working rig winch motor transmission device, belonging to the technical field of well-working rig winch motors. It solves the problem of large space occupation in the transmission system of existing vehicle-mounted well-working rig winch motors. It includes a hollow shaft motor, with a drum-shaped gear coupling installed inside the hollow shaft. One end of the drum-shaped gear coupling is fixedly connected to one end of the hollow shaft, and the other end is fixedly connected to the winch input shaft. A connecting key for insertion into the winch input shaft is provided on the connection end of the drum-shaped gear coupling and the winch input shaft. This utility model, by incorporating a drum-shaped gear coupling within the hollow shaft motor, eliminates intermediate structures such as a gearbox and tensioning device, significantly reducing the size of the transmission device, meeting the space constraints of the vehicle-mounted platform, and eliminating redundant components such as the protective cover, thus reducing the failure rate and maintenance costs.
