Abstract
Revolving actuator for hydraulic revolving a shaft, comprising a bowl rotor (3) arranged axially rotatable in a housing comprising two housing halves (1, 2), where the bowl rotor (3) is adapted to be connected with a shaft and thereby providing an upper spheric bearing for the shaft, passages thereby providing the housing halves (1, 2) with pressurized hydraulic fluid, the inner walls of the two housing parts (1, 2) thereby having a spheric shape and being sealingly abutting against the bowl rotor (3), the bowl rotor (3) comprising a circumferential recess (4) at the equator, the bowl rotor (3) having at least one partition wall (5) closing the recess (4), a cylinder limitation (8) being arranged in each recess (4) and being rigidly connected with the housing halves (1, 2), and hydraulic connections to the cylinder rooms (6, 7) established in the recesses (4) thereby ensuring supply of hydraulic pressure in the cylinder rooms (6, 7) at each side of each partition wall (5).
Description
Technical field
The present invention relates to a kind of hydraulic revolving actuator.
Background technique
For example disclose a kind of rotary actuator of the above-mentioned type in patent document NO 164648, its structural design is comparatively complicated, and comprises many single parts.In addition, its structure more greatly and very heavy.The actuator of the above-mentioned type that can reverse especially is used as helmsman except other purposes, be used to drive the rudderpost on the boats and ships.
Requirement to this helmsman is: structure especially simply, also can accurately be regulated and deflection vein can be dashed the physics rotation that accurately and directly changes rudderpost into.In addition, for such clockwise and anticlockwise actuator, the size of revolving actuator should be as much as possible little with respect to its actual force.
Summary of the invention
Thereby, the purpose of this invention is to provide a kind of reversible actuator, it can satisfy above-mentioned requirement, and has very little size and very light weight, and in addition, this reversible actuator should include only several separate parts seldom.In manufacture process and install and subsequently using process in, this will bring very large benefit.
Employing can make structure become very simple, and make outside dimension become very little according to hydraulic revolving actuator of the present invention.Can realize above-mentioned technique effect according to revolving actuator of the present invention, revolving actuator of the present invention is limited by feature listed in the claim.
Description of drawings
In the accompanying drawings:
Fig. 1 is a perspective view, and it has been represented according to revolving actuator of the present invention;
Fig. 2 is the horizontal cross of revolving actuator; And
Fig. 3 is the sectional drawing of being done along the III-III line among Fig. 2.
Embodiment
Revolving actuator comprises a upper half-shell 1 and second housing 2, and the two halves housing is suitable for respect to the single parts that will be rotated, is tightened to together by bolt clip up and down.For example be used as helmsman according to revolving actuator of the present invention, be used to drive a rudderpost, in this application, two halves housing 1,2 is fixed on the deck of steamer etc.Should fix can also be simultaneously for rudderpost provides upper support, and rudderpost is not wherein expressed in the drawings, but it extends through from the drawing of Fig. 3 place.
By in the housing that forms of lower half shell 1,2, be provided with a bowl-shape rotor 3, it has constituted the top spherical bearing of rudderpost, and is used for rudderpost is fixed.Also be provided with Sealing in housing, the Sealing butt the inwall and the bowl-shape rotor 3 of two halves housing 1,2.
Bowl-shape rotor 3 comprises the depression 4 that is provided with around its equatorial line, and these depressions are with the inwall of housing 1,2, and the both sides of next door 5 have respectively formed an interior ring cavity, have for example just expressed several next doors wherein among Fig. 2.The path 10 corresponding with hydraulic line exerted pressure to piston chamber 6 and piston chamber 7 respectively, and correspondingly mutual opposed piston chamber designed by this way: make to have a pressure difference between two pressure chambers 6,7.Bowl-shape rotor 3 is rotated, and then the bar axle that is connected with rotor is also rotated, bar axle wherein for example is mounted in the rudder stock on the boats and ships, thereby rudder for ship is also rotated.
Piston chamber 6 and 7 is surrounded by these members: next door 5, cylindrical shape link 9, two halves housing 1 and 2 and two columnar bounding meanss 8 up and down, bounding means 8 is rigidly secured on the two halves housing, and is arranged in the depression 4.More very importantly be: must seal mutually between these parts.
Revolving actuator according to the present invention includes only several separate parts seldom, and this actuator also is very compact.
Claims (1)
1. revolving actuator, be used for hydraulic driving one bar axle and make its rotation, it comprises: a bowl-shape rotor (3), it axially is arranged in the housing rotationally, this housing is made up of two and half housings (1,2), in housing, bowl-shape rotor (3) is suitable for being connected with a bar axle, thereby this rotor provides a top spherical bearing for described bar axle; Passage, by passage in two halves housing (1,2), carry the pressurization after hydraulic fluid, the inwall of two housings parts (1,2) is spherical, and butt bowl-shape rotor (3) hermetically, it is characterized in that: bowl-shape rotor (3) comprise be positioned on its equatorial plane, circumferential depression (4), bowl-shape rotor (3) has at least one next door (5), and it has sealed described depression (4); And in each depression (4), being provided with a bounding means cylindraceous (8), bounding means (8) is rigidly connected with two halves housing (1,2); In depression (4), be shaped on the hydraulic channel that leads to piston chamber (6,7), guarantee thus to apply hydraulic pressure to the piston chamber (6,7) of both sides, each next door (5).
