Abstract

The invention discloses a submerged reducer, which comprises a lower box body and an upper box body. The input hole of the upper box body is provided with a first bearing, the first bearing is pierced with an input shaft, and the output shaft of the upper box body is A second bearing is provided in the hole, and an output shaft is pierced on the second bearing; a small bevel gear is provided at the inner end of the input shaft, and a large bevel gear meshing with the small bevel gear is provided at the inner end of the output shaft; the lower box The lower hole at the end of the body, the two lower semicircular holes, and the upper end surface of the lower box are provided with a lower installation groove, the lower installation groove is embedded with a lower gasket, and the upper surface of the lower gasket is provided with water retaining ribs. The upper hole at the end, the two upper semi-circular holes and the lower end surface of the upper box body are provided with an upper installation groove, the upper installation groove is embedded with an upper gasket, and the lower end surface of the upper gasket is provided with rib grooves; when the upper box body When it is fixed on the lower box body, the upper sealing pad and the lower sealing pad are extruded and fit, and the water retaining ribs are embedded in the rib grooves and have an interference fit with the rib grooves. The invention has good waterproof performance and can adapt to underwater operations.

Description

technical field [0001] The invention relates to a reducer, in particular to an underwater reducer with waterproof function. Background technique [0002] The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. Due to the requirements of working conditions, some reducers need to be used in water. Therefore, their waterproof performance is relatively high. However, the existing reducers have poor waterproof performance and are not suitable for underwater operations. Therefore, there is an urgent need to ...
