Abstract

The invention discloses a gearbox used for an aircraft tractor. The gearbox comprises a box. Bearing positions are arranged on the side walls of the two ends of the box correspondingly. A bearing is mounted in each bearing position. A rotary shaft is rotationally connected into each bearing. Rectangular grooves are formed in the two sides of the box symmetrically. Cylindrical sleeves are symmetrically mounted in the rectangular grooves correspondingly. Sponge bars are mounted in the cylindrical sleeves correspondingly. The rectangular grooves are filled with water solutions. Mounting plates are rotationally connected to the rotary shafts correspondingly. Mounting grooves are symmetrically formed in the mounting plates correspondingly. A ventilating net is clamped to each mounting groove and wrapped with a spongy layer. The spongy layers are connected with the corresponding sponge bars. According to the gearbox used for the aircraft tractor, the water solutions in the rectangular grooves can be adsorbed through the sponge bars and enter the spongy layers, then fan blades rotate, accordingly, moisture of the spongy layers fast evaporates, the temperature in the box is lowered, and the situation that a high temperature causes part ageing is avoided.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a gearbox for an aircraft tractor. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. [0003] The application number is: CN 203836169 U discloses a gearbox, and the technical solution adopted in the present invention is: a gearbox, including: a box body, a drive motor is arranged on the upper side of the box body, and the motor of the drive motor The shaft is connected with the transmission shaft rotated on the box body through the clutch, the transmission me...
