Embodiment Construction

[0020] The following describes the patent of the present invention in further detail with reference to the drawings and specific implementation.

[0021] The rotary vane hydraulic steering gear is mainly composed of the following parts: the upper cylinder head 13 and the cylinder block 15 are connected by connecting bolts, and the lower cylinder head 16 and the cylinder block 15 are connected by bolts. The stationary blade group 18 is connected to the cylinder block 15 and the upper cylinder head 13 by connecting bolts, and a moving blade group 19 is installed on the rotor 17, and the two are connected by bolts. The scale plate 12 is connected with the rotor 17 by bolts, and the lifting ring 14 is welded to the upper cylinder head 13.

[0022] The further feature of the sealing device of the novel rotary vane hydraulic steering gear of the present invention is that the two or more vane groups 18 are connected to the inner wall of the cylinder 15 by bolts, and the shape of the inner...

Abstract

The invention belongs to the field of marine rotary vane hydraulic steering engines and particularly relates to a movable vane set sealing device of a novel rotary vane hydraulic steering engine. Themovable vane set sealing device comprises sealing ring pressing plates, sealing rings and movable vanes, wherein the movable vanes are connected to a rotor through connection bolts; two sealing ringsand two sealing ring pressing plates are arranged; the two sealing rings are respectively mounted on two sides of each movable vane, and the two sealing ring pressing plates are respectively arrangedon two sides of each sealing ring and are respectively fixed on the movable vane; a lip opening which is turned outwards is arranged on one side of each sealing ring; and a groove opening is formed ineach sealing ring. According to the movable vane set sealing device, the internal sealing performance of the rotary vane hydraulic steering engine is added; the internal leakage of hydraulic oil of the rotary vane hydraulic steering engine is solved, so that the rudder stabilizing performance of the hydraulic steering engine is greatly improved; the rudder operating flexibility of the rotary vanehydraulic steering engine is improved; and all the advantages of the original rotary vane hydraulic steering engine are retained.

Description

Technical field [0001] The main product involved in the patent of the invention belongs to the field of marine rotary vane hydraulic steering gear, and specifically relates to a new type of rotary vane hydraulic steering gear sealing device for the rotor blade group. Background technique [0002] Marine hydraulic steering gear is the source of power to control the rotation of the rudder blades. The rotation of the rudder blades changes the navigation of the ship. That is, the action of the hydraulic steering gear determines the navigation and safety of the ship. Therefore, the hydraulic steering gear is one of the most important equipment on the ship. One. [0003] The hydraulic steering gears currently used on ships are mainly: swing cylinder type, shift fork type and rotary vane type. Due to its torque output curve is a straight line, the rotary vane hydraulic steering gear does not change with the rotation of the rudder angle, and the output torque performance is better than th...
