Abstract
The invention discloses a kind of rotation oil circuit connection device, the oil circuit for connecting rotation switching.The invention mainly comprises have outer housing, bearing, sealing ring, oil circuit interface, snap ring, sealing cover, gland, rotation axis, oil circuit, outage.Mainly by being fitted with rotation axis in columnar structured outer housing, bearing, snap ring, sealing ring are set in rotation axis, oil discharge outlet is also equipped on outer housing can be by the pressure reduction for the high pressure reserve that Inner inside outer housing is let out.Using after the present invention compared with can be played than the prior art prevent from leading to the problem of high pressure reserve in outer housing after so that outer housing strength is followed rotation axis rotation destroys sealing ring and rotation axis connect with outer housing the problem of inconvenience installed.
Description
Technical field
The present invention relates to a kind of rotation oil circuit connection devices.
Background technology
There is its internal high pressure reserves that generates, and outer housing strength to be made to follow for rotation oil circuit connection device in the prior art
The problem of rotation axis rotation destroys sealing ring and rotation axis connect the inconvenient problem of installation with outer housing.
Invention content
The object of the present invention is to provide a kind of rotation oil circuit connection devices, can solve above-mentioned outer housing strength in the prior art
The problem of following rotation axis rotation to destroy sealing ring and rotation axis connect the inconvenient problem of installation with outer housing.
A kind of rotation oil circuit connection device of the present invention, mainly includes outer housing, bearing, sealing ring, rotation axis, oil circuit, outside
Shell is cylindrical in shape structure and is fitted with bearing, snap ring, sealing ring by rotation axis, sealing cover, gland inside it, has on outer housing
Oil circuit interface, oil extraction interface, the oil circuit in rotation axis are connected with the rotation of oil circuit interface, rotation axis and the height formed inside outer housing
Reserve is pressed to be connected with oil discharge outlet rotation, gland is compressed by screw thread with outer housing and connected.
Using such structure, when the present invention is worked in rotating hydraulic equipment, the internal high pressure storage generated
Oily area exists when building the pressure, and oil discharge outlet can timely be built the pressure venting, to make after preventing its internal high pressure reserve to build the pressure
The problem of outer housing strength follows rotation axis rotation to destroy sealing ring.Again because disassembly and installation only needs to answer when of the invention
This is dismantled or is installed the extraction that can complete its internal rotational axis or is transferred to, therefore can eaily realize in it
It dismantles or safeguards in portion.
Description of the drawings
Below in conjunction with attached drawing, the present invention is described in further detail.
Fig. 1 is the main view cross-sectional view of the present invention.
Specific implementation mode
As shown in Figure 1, the present invention rotate oil circuit connection device, mainly include outer housing 1, bearing 2, sealing ring 3, rotation axis 10,
Oil circuit 11.Outer housing 1 be cylindrical in shape structure inside it by rotation axis 10, sealing cover 8, gland 9 be fitted with bearing 2, snap ring 6,
Sealing ring 3.There are oil circuit interface 4, oil extraction interface 12 on outer housing 1；Oil circuit 11 in the rotation axis 10 is revolved with oil circuit interface 4
Switching is logical.The high pressure reserve 5 that rotation axis 10 is formed with 1 inside of outer housing is connected with the rotation of oil discharge outlet 12.Gland 9 and outer housing
1 compresses connection by screw thread.
As shown in Figure 1, when manufacturing and using the present invention, lateral surface should be equipped with sealing ring 3 in sealing cover 8.
