An oil-lubricated electric steering gear with position locking function

Abstract

The invention provides an oil lubrication electric steering engine with a position locking function and relates to the field of design of deep-sea outboard electric steering engines. The oil lubrication electric steering engine with the position locking function comprises a moment motor, a ball screw pair, a self-pressurized fuel tank, a locking piston rod, a locking valve block, an electromagnetic locking valve and a steering engine housing, wherein the steering engine housing is of a shell structure with a hollow cavity inside; the moment motor is fixedly mounted at one end, in the axial direction, of the cavity of the steering engine housing in the axial direction; the ball screw pair is fixedly mounted on the axis of the moment motor in the axial direction; the locking piston rod is coaxially in abut joint with the ball screw pair; the self-pressurized fuel tank is horizontally arranged at the top of the steering engine housing; an open end of the locking valve block is arranged onthe external wall of one end, in the axial direction, of the self-pressurized fuel tank in the axial direction in a sleeving manner; the electromagnetic locking valve is fixedly mounted at the external end, in the axial direction, of the locking valve block; and the cavity of the steering engine housing is filled with lubrication oil liquid. Except for a steering function, the oil lubrication electric steering engine with the position locking function also has functions such as a seawater pressure compensation function, an any position power-off locking function, and a lubrication oil liquidautonomous circulation filtering function.

Description

technical field [0001] The invention relates to the design field of a deep-sea outboard electric steering gear, in particular to an oil-lubricated electric steering gear with a position locking function. Background technique [0002] The electric steering gear has the advantages of simple structure and low cost, and is widely used in the field of displacement servo. However, the conventional electric steering gear is mostly lubricated with grease, does not have the function of external pressure compensation, the position locking mechanism is complicated, and the reliability is poor, which cannot meet the requirements of deep-sea outboard work. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide an oil-lubricated electric steering gear with position locking function, which not only has the steering function, but also has seawater pressure compensation, power-off locking at any ...
