Abstract
The invention discloses a through shaft type rotatable hydraulic connecting piece. The through shaft type rotatable hydraulic connecting piece comprises a through shaft (1) and a shell body. The shell body is hollow. An oil cavity (11) is formed in the shell body. The through shaft (1) is rotationally arranged in the shell body, and the two ends of the through shaft (1) extend out of the shell body. A threaded hole (8) for enabling an external oil pipe and the oil cavity (11) to communicate is formed in the side surface of the shell body. An axial hole (10) communicating with the oil pipe is formed in one end of the through shaft (1). A radial hole (9) for enabling the oil cavity (11) and the axial hole (10) to communicate is formed in the radial direction, located in the oil cavity (11), of the through shaft (1). According to the through shaft type rotatable hydraulic connecting piece, an oil transportation shaft can be matched with a movement shaft to move, and movement connection is achieved.
Description
Technical field
The present invention relates to hydraulic connectors, the most rotatable hydraulic connectors.
Background technology
Hydraulic connectors is at the most common equipment of Hydraulic Field, has movable and the most movable.Needing the connection occasion of motion, main structure is telescopic, has the axle of pipeline to be nested in another hollow axle in rotation, only exposes the side of logical oil.But in some occasion, need the axle of output oil to be connected on a kinematic axis, with one plays motion, telescopic cannot meet this requirement.
Summary of the invention
The purpose of the present invention solves telescopic exactly and exposes oil-guiding shaft one end, it is impossible to the problem of other kinematic axis routing motion, it is provided that a kind of shaft type rotatable hydraulic connector.
The present invention adopts the following technical scheme that: a kind of shaft type rotatable hydraulic connector, including axis and housing；Described housing hollow, it is internally formed oil pocket；Described axis is located in described housing rotationally and described housing is stretched out at two ends；The screwed hole of external oil pipe and described oil pocket it is communicated with at described housing side opening；Offer, in described axis one end, the axial hole connected with oil pipe, be positioned at radially offering and the radial hole connecting described oil pocket and described axial hole of oil pocket at described axis.
Described housing includes left shell and right shell body；Described left shell end is threaded connection with described right shell body end and coordinates.
In described housing, axis and described enclosure interior sidewall junction are provided with movable sealing structure.
Described movable sealing structure includes dynamic seal and Glais ring；Described dynamic confidential paper is connected with described case inside wall by screw thread；Described Glais ring is arranged between described housing and described dynamic seal.
Beneficial effects of the present invention: oil-guiding shaft of the present invention can be with kinematic axis routing motion, it is achieved be rotatably connected.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Wherein, 1 is axis, and 2 is dynamic seal, and 3 is left shell, and 4 is bearing, and 5 is inner ring, and 6 is outer ring, and 7 is sealing ring, and 8 is screwed hole, and 9 is radial hole, and 10 is axial hole, and 11 is oil pocket, and 12 is right shell body.
Detailed description of the invention
Below in conjunction with the accompanying drawings technical scheme is described in detail:
As it is shown in figure 1, the shaft type rotatable hydraulic connector of the present invention includes axis 1, the housing being enclosed within described axis 1.Described housing is complemented each other to form by left shell 3 and right shell body 12.Left shell 3 and right shell body 12 are hollow cylindrical structure, and left shell 3 end is threaded connection with right shell body 12 end and coordinates, and are sealed by sealing ring 7；It is beneficial to assembling.Forming oil pocket 11 in housing, the hollow position at left shell 3 and right shell body 12 is provided with bearing 4, and axis 1 is fixed in housing by bearing 4, and rotates in housing.Offering axial hole 10 in the axial direction of axis 1, radially offer radial hole 9 what axis 1 was positioned at oil pocket 11, axial hole 10 connects with radial hole 9, thus connects with oil pocket in housing 11.External oil pipe connects with axial hole 10, offers screwed hole 8 on left shell 3, and external oil pipe is connected with the oil pocket 11 in housing by screwed hole 8.So, the radial hole 9 on screwed hole 8, oil pocket 11, axis 1 and axial hole 10 collectively form oil circuit.
Because relatively rotating between axis 1 and housing, for making oil not reveal, it is provided with movable sealing structure in axis 1 side and enclosure interior sidewall junction.Movable sealing structure includes dynamic seal 2 and Glais ring；Dynamic seal ring 2 uses politef, is connected with case inside wall by screw thread.Described Glais ring is arranged between described housing and described dynamic seal 2, including inner ring 6 and outer ring 5.The other end of the obstructed oil of axis 1 is connected by shaft coupling with the axle needing associated movement.
The foregoing is only one embodiment of the present of invention, not in order to limit the present invention, within all thought in the present invention and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
