Abstract

A rotary vane steering gear comprises a rotor, a cylinder block, rotor vane supports, rotor vanes, cylinder block vane supports, cylinder block vanes and two cover plates, and is characterized in thatthe cylinder block is formed by combining an upper side cylinder block and a lower side cylinder block; the upper side cylinder block and the lower side cylinder block are of a symmetrical structure;the inner wall of the upper side cylinder block and the inner wall of the lower side cylinder block are provided with upper side cylinder block vane supports and lower side cylinder block vane supports correspondingly; after the upper side cylinder block and the lower side cylinder block are combined up and down, the upper side cylinder block vane supports and the lower side cylinder block vane supports are combined into the whole cylinder block vane supports; the rotor vane supports are arranged in the middle of the rotor, and the rotor vane supports and the rotor are of an integrally formedstructure; the rotor is mounted in the cylinder block; the rotor vanes are mounted in the rotor vane supports; the cylinder block vanes are mounted in the cylinder block vane supports; the two coverplates are in an annular shape and are packaged on the two sides of the cylinder block correspondingly; and the two ends of the rotor extend out of the cover plates.

Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment sealing, in particular to a rotary vane steering gear and an installation method thereof. Background technique [0002] Rotary vane steering gear or vane hydraulic swing cylinder is a hydraulic drive device that converts hydraulic energy into mechanical energy and converts linear motion into reciprocating rotary motion. The vane hydraulic swing cylinder has compact structure, large torque, and good stability. Advantages, the vane hydraulic swing cylinder connects the driven equipment and the cylinder rotor through a key, the oil acts on the rotor vane, and converts the oil pressure that pushes the vane to the rotor, and then drives the driven equipment connected by the shaft through the rotor drive equipment. Now it is mainly used in aerospace, ships, automobiles, etc., and the prospect is very broad. The existing hydraulic oscillating cylinders mainly have the following problems: 1....
