Closed exhaust rotary vane type steering gear

Abstract

The invention relates to a closed exhaust rotary vane type steering gear. The steering gear comprises a steering gear box and a rotor inside the steering gear box, wherein the two ends of the rotor are contacted with the steering gear box through a sealing strip and a hydraulic cavity respectively; the top of the rotor is provided with an upper sealing ring, an upper bush and an end cover; the bottom of the rotor is provided with a lower sealing ring and a lower bush; an oil drainage pipeline is arranged at a position on the side part of the rotor and close to the hydraulic cavity; one end ofthe oil drainage pipeline is communicated with an annular groove between the rotor and the end cover, and the other end of the oil drainage pipeline is contacted with a friction plate between the rotor and the steering gear box; the annular groove is communicated with the hydraulic cavity through an air outlet pipeline, a closed exhaust module and an air inlet pipeline in turn; and the closed exhaust module is connected with the end cover through a plate. Due to the design of the steering gear, waste of hydraulic oil is avoided, environmental pollution is prevented, the steering gear has relatively small size and relatively high safety, is easy to install and maintain and can lubricate the friction plate and the lower bush while exhausting, and the mechanical efficiency of the rotary vanetype steering gear can be improved.

Description

technical field [0001] The invention relates to a rotary vane steering gear, in particular to a rotary vane steering gear with closed exhaust, which is particularly suitable for the built-in discharge of gas and hydraulic oil in a hydraulic chamber on the rotary vane steering gear. Background technique [0002] The steering gear is an important equipment to ensure the safe navigation of the ship, which is used to maintain or change the course of the ship. Rotary vane steering gear is a new type of steering gear. Its working principle is similar to that of a vane hydraulic motor. It converts hydraulic energy into mechanical energy, and the final output is the rotation of the rotor, which is connected to the rudder stock by keys or other means. , the rotation of the rotor drives the rotation of the rudder stock, thus realizing the steering process. Rotary vane steering gear is favored by users for its small size, light weight, small footprint, simple installation, convenient ...
