The invention belongs to the technical field of aviation devices, and discloses a worm gear and worm transmission retractable landing gear which comprises a mounting frame, a motor and a worm located on one side of the motor are arranged in the mounting frame, a first synchronous belt wheel is arranged on an output shaft of the motor, a second synchronous belt wheel located outside the mounting frame is arranged on the worm, and the worm gear and worm transmission retractable landing gear is arranged on the mounting frame. A synchronous belt is connected between the second synchronous pulley and the first synchronous pulley; a worm wheel is further meshed with the worm, a transmission shaft is arranged in the center of the worm wheel in a penetrating mode, a retractable rocker arm is arranged on the transmission shaft and provided with a steering assembly, a buffer and a buffer outer frame located on one side of the buffer are arranged on the steering assembly, and a machine wheel rocker arm is jointly and rotationally connected to the buffer and the buffer outer frame. And the airplane wheel rocker arm is rotationally connected with an airplane wheel. The unmanned aerial vehicle landing gear solves the problem that an existing unmanned aerial vehicle landing gear cannot give consideration to weight, size and stability, and is suitable for stable take-off and landing of an unmanned aerial vehicle.
