The invention discloses a double-gear-driven double-propeller pitch-adjustable full-revolving thruster which comprises a thruster body, a variable pitch type front propeller and a fixed pitch type rear propeller and further comprises an input shaft, wherein the bottom end of the input shaft is in transmission connection with a bevel gear pair through a coupler; a front transmission shaft and a rear transmission shaft are arranged on the two sides of the bevel gear pair respectively and are parallel to the bevel gear pair, a front bevel gear pair is arranged at the bottom end of the front transmission shaft, and a horizontally-arranged front thrust shaft is arranged on the lower portion of the front bevel gear pair. The invention provides an efficient and high-reliability ship thruster which is characterized in that a front propeller and a rear propeller are driven by two pairs of spiral bevel gears respectively, the variable-pitch front propeller is in a variable-pitch form, the fixed-pitch rear propeller is in a fixed-pitch form, two transmission systems and the propellers are mutually independent, and when one is damaged, the use of the other is not influenced.
