Embodiment Construction

[0022] Such as Figure 1.1-2.3 As shown, the present invention discloses a hydraulic single-blade swing cylinder, which is manufactured by corrosion-resistant alloy, and mainly consists of a front sealing cover 1, hexagon socket head screws (2, 8, 11, 13, 14, 18), bearings (3, 15), key (4, 17), rotating shaft 5, front end cover 6, O-shaped sealing ring (7, 9, 20, 23, 25), fixed blade 10, housing 12, package encoder 16, The water outlet 19, the rear sealing cover 21, the rear end cover 22, the rotating blade 24 and other parts are composed, and thus constitute two working water chambers, and the rotating blade is controlled by controlling the water inflow and outflow sequence and the flow rate of the A port and the B port. 24, and then control the steering and the rotating speed of the rotating shaft 5. The specific implementation manner will be further described below.

[0023] When the rotating shaft 5 needs to rotate forward, the high-pressure water enters the left working...

Abstract

The invention discloses a water-hydraulic single-vane type oscillating cylinder, and belongs to key parts of underwater robot joints. The water-hydraulic single-vane type oscillating cylinder is mainly composed of a front end cover, a front sealing cover, a bearing, a rotating shaft, a rotating vane, a fixed vane, a housing, a packaging encoder, a rear sealing cover, a rear end cover and the like, and accordingly two working water cavities are formed. The rotating vane and the fixed vane are both provided with specially-made rectangular sealing rings and pressing and buffering devices; and the bearing is a water lubricating bearing. The water-hydraulic single-vane type oscillating cylinder adopts an all-water lubricating mode and is integrated with the encoder so as to be simple and compact in structure and capable of precisely controlling the output position and speed of the rotating shaft, and be widely applied to driving and controlling of joints of water and underwater robots.

Description

technical field [0001] The invention belongs to the technical field of water hydraulics, belongs to key components of joints of underwater robots, relates to rotary actuators of joints of underwater robots, and particularly relates to a single-blade swing cylinder of water hydraulic pressure. technical background [0002] The development of underwater robots is a technical field that various countries are competing to develop. Whether it is underwater salvage, underwater resource exploration or underwater training, efficient underwater operation tools, namely underwater robots, are required. As the rotary actuator of the underwater robot joint, the swing hydraulic cylinder is a key element that determines the speed and stability of the underwater robot's movement. [0003] The swing hydraulic cylinder is also called the swing hydraulic motor. Its outstanding advantage is that the load can obtain reciprocating swing motion without any mechanism. It can be said that the swing ...
