Abstract

The invention belongs to the field of unmanned ocean robots and specifically relates to a steering gear of an unmanned ocean robot. The steering gear comprises a rudder bearing assembly, a rudder blade as well as a hydraulic cylinder support, a rear rotation shaft, a hydraulic cylinder, a front rotation shaft and a rudder handle located in a robot carrier, wherein the hydraulic cylinder support is installed in the robot carrier, and the hydraulic cylinder is connected to the hydraulic cylinder support by the rear rotation shaft; the rudder bearing assembly passes through a rudder bearing hole formed in the robot carrier and is installed on the robot carrier; and one end of the rudder handle is connected to a piston rod of the hydraulic cylinder by the front rotation shaft, the other end is connected to the end of a rudder shaft of the rudder bearing assembly, wherein the end is in the robot carrier, and the rudder blade is fixed and connected to the other end of the rudder shaft located outside the root carrier. The steering gear provided by the invention is designed according to motion theories of a planar second-level rod group; the structural design is compact, simple and highly reliable; and dual-way axial loads can be borne. According to the invention, the structure is simple and compact; overall installation and disassembly can be achieved; maintenance is easy; and the steering gear is applicable to unmanned ocean robots and other middle and large underwater robots.

Description

technical field [0001] The invention belongs to the field of unmanned marine robots, in particular to a steering device for unmanned marine robots. Background technique [0002] The unmanned marine robot is a large underwater robot, which mainly relies on the steering gear to realize the movement of six degrees of freedom underwater. Steering gear occupies a crucial position in marine robots. It must not only ensure strength requirements, but also ensure reliable sealing and low rotation resistance. The steering gear on the unmanned marine robot carrier needs to have high reliability, but the installation space is very limited, which puts forward strict design requirements for the steering gear. [0003] In order to solve this problem, it is necessary to design a steering gear with compact and simple structure, high reliability, and convenient installation and maintenance. At present, traditional underwater robots mainly rely on electric steering gears for manipulation. Th...
