Abstract
The utility model discloses a coupling joint, which belongs to a mechanical link mechanism; in particular to a coupling joint which is especially used between a control mechanism and an adjusting mechanism. The coupling joint is composed of a connecting sleeve, a joint, and a shaft pin. The inner part of the bore diameter of the joint is provided with a spherical joint bearing which makes the rotation of the connecting joint flexible; the clamping and rolling phenomenon in the prior art can be overcome, and the installation of the control mechanism is convenient. Simultaneously, the end surface of the bore diameter of the joint which is dust-proof through adopting a sealing ring and a sealing cover can be also used as a refuelling chamber, and the service life of the coupling joint can be increased. The utility model is suitable for the control mechanism of the industries, such as the power station, metallurgy, chemical industry, petroleum, light textile, etc. and the coupling joint of the adjusting mechanism.
Description
The utility model relates to a kind of mechanical linkage, particularly a kind of joint that is connected that is used to connect control mechanism and controlling mechanism.
Connecting the joint is requisite auxiliary equipment in industrial automation and the telecontrol engineering, is widely used in industry such as power station, metallurgy, chemical industry, oil, light textile.Control mechanism is by connecting the joint, connecting rod with at a distance of in addition 5 meters outer controlling mechanisms link to each other.At present, connect the joint in the domestic prior art and mostly adopt the V shape joint, this pattern, because joint and the flexible rotatability of pivot pin are poor, the deflection of connecting rod is difficult to compensation, pivot pin usually causes that with the gap of nipple orifice being connected the joint card rolls.In order to improve switching performance, very high to the mounting point size requirement of control mechanism, but can not fundamentally change the generation that its card rolls phenomenon, and also it is serious to connect the joint laying dust, the lubricating oil filling difficulty, and working life is short.
For addressing this problem, West Germany Hartmamn ﹠ Braun company adopts spherical linkage structure to pivot pin and joint, can stop card effectively and roll phenomenon, but this constitutional detail processing request height also needs special device.
The purpose of this utility model provides a kind of improved connection joint, makes to connect to close energy-conservation flexible rotation, eliminates card and rolls phenomenon, improves working life, makes things convenient for the installation of control mechanism.
The purpose of this utility model is achieved in that the connection joint of being made up of connecting sleeve, joint, pivot pin.A spherical joint bearing is arranged, the internal diameter of bearing and pivot pin external diameter close proximity in the joint aperture.
A sleeve is arranged on the pivot pin external diameter, and an end of sleeve contacts with the spherical joint bearing face, and an end in joint aperture has a seal ring, and the other end has a sealing cover.
The utility model compared with prior art owing to adopted the spherical joint bearing, makes to connect the joint rotation flexibly, eliminates card and rolls phenomenon, and part processing is convenient, is convenient to the installation of control mechanism.Adopt sealing configuration to prevent dust, can make fueling cavity again, improve and connect joint working life.
Description of drawings
Fig. 1 is the utility model and control mechanism, the schematic representation that controlling mechanism connects, and control mechanism pivoted arm 10 among the figure connects joint 11, connecting rod 12, controlling mechanism pivoted arm 13.
Fig. 2 is a section of structure of the present utility model.
Seal ring 1 among the figure, sleeve 2, pivot pin 3, sealing cover 4, spherical joint bearing 5, connecting sleeve 6, joint 7, connecting rod 8, control mechanism or controlling mechanism pivoted arm 9.
Embodiment of the present utility model as shown in drawings, it is existing that the utility model is described in further detail in conjunction with the accompanying drawings.
With reference to shown in Figure 2, a spherical joint bearing 5 is housed in the aperture of joint 7, and brearing bore matches with the pivot pin external diameter, by the spherical joint bearing joint and pivot pin can be rotated flexibly like this, eliminated the card that causes because of the gap and rolled phenomenon, joint and pivot pin are easy to process simultaneously.Sleeve 2 is enclosed within on the pivot pin external diameter.One end is used for preventing the axial displacement of joint shaft bearing near the joint shaft bearing plane.The pivoted arm 9 of control mechanism or controlling mechanism is housed on the one end cylindrical of pivot pin 3, and its mutual Conncetion cimension meets national professional standard ZBy217-84.Rotation pivoted arm 9, by pivot pin 3, spherical joint bearing 5 drives joint 7 and connecting rod 8 and moves.Connecting rod 8 links to each other with joint 7 by connecting sleeve 6, and screw thread one end on the joint 7 is that the left-handed the other end is dextrorotation, and bar 8 can regulate that are rotatably connected during use connect the distance size, install easy to adjust.Joint 7 is ± 5 ° with the vertical axis corner of pivot pin 3, as shown in the figure, allows the deflection ranges of connecting rod like this, makes control mechanism easy for installation.At two ends, joint 7 aperture seal ring 1, sealing cover 4 are housed, enter joint shaft bearing, go back the function of double as fueling cavity, improve to connect joint working life to prevent dust.
Claims (3)
1, a kind of connection joint is made up of connecting sleeve 6, joint 7, pivot pin 3, it is characterized in that the spherical joint bearing 5 that has closely to contact with pivot pin 3 external diameters in joint 7 apertures.
2, connection according to claim 1 joint is characterized in that an end that is positioned at spherical joint bearing 5 on pivot pin 3 external diameters has a sleeve 2.
