Abstract
The invention discloses a four-point thrust angular contact type rotating joint and belongs to the field of the mechanical manufacturing technology. A rotating joint fixing body and a hydraulic rotating fixture are connected into a whole body through bolts. An oil return pipeline a and an oil return pipeline b are formed in the rotating joint fixing body. Two circuit openings are connected to an oil outlet of a rotary body. An oil hole A and an oil hole B are located in the rotary body. An O-shaped ring and a sealing ring are arranged between the fixing body and the rotary body. A four-point thrust angular contact ball bearing is arranged at the tail end of the fixing body and is compressed through an end cover. The four-point thrust angular contact type rotating joint has the advantages that the four-point thrust angular contact ball bearing and an annular ball bearing are matched with the rotating joint, the four-point thrust angular contact ball bearing bears all axial loads input to the axial direction of the fixing body by the rotary body, and the rotating joint is made to maintain the axial rotating stability in a working chamber through the combined utilization of the four-point thrust angular contact ball bearing and the annular ball bearing.
Description
technical field4 thrust angular contact formula swivel joints, belong to Machining Technology field.
background techniqueproduct is in mechanical processing process, relating to hydraulic power unit provides the fixture of clamping force, during this hydraulic fixture work, to be rotated, for guaranteeing the normal pressure of the unimpeded and maintenance oil circuit of hydraulic circuit in rotary course, need to the swivel joint that can rotate freely be installed at hydraulic fixture and pipeline joint, because the clamping structure of some hydraulic fixture is complicated, the processing work time is long, higher hydraulic pressure need to be provided, especially working pressure more than 40MPa, common swivel joint cannot meet the usage requirement of specialities machining.
summary of the inventiondefect in view of prior art existence, the object of this invention is to provide a kind of 4 thrust angular contact formula swivel joints, realization can guarantee the object of the normal rotation of hydraulic fixture in high-pressure environment, and has easy accessibility, easy to maintenance, smooth running, lasting reliable, feature that friction ractor is little.
For achieving the above object, the technology used in the present invention solution is: 4 thrust angular contact formula swivel joints, swivel joint fixed body and hydraulic rotating clamp are bolted and are integral, inside has oil returning tube a, oil returning tube b, two return openings are connected on the oil outlet of solid of rotation, oilhole A, oilhole B is positioned on solid of rotation, mounting O-shaped rings and seal ring between fixed body and solid of rotation, 4 angular contact thrust ball bearings are arranged on the end of fixed body, by end cap, compressed, radial ball bearing is arranged on the thin axle of fixed body, by end cap location and compression.
Described seal ring is teflon seal ring.
Described O type circle is O type rubber seal.
4 thrust angular contact formula swivel joints, its beneficial effect is: owing to adopting 4 thrust angular contact formula swivel joint technology, 4 angular contact thrust ball bearings coordinate swivel joint with radial ball bearing, 4 angular contact thrust ball bearings bear whole thrust loads that solid of rotation is input to fixed body axial direction, by being used in combination with radial bearing, make swivel joint in working room, preserve the stability of axis rotation.

Fig. 1 reference character is as follows: 1, fixed body, 2, solid of rotation, 3, O type circle, 4, seal ring, 5,4 angular contact thrust ball bearings, 6, radial bearing, 7, end cap, 8, oil returning tube a, 9, oil returning tube b, 10, oilhole a, 11, oilhole b.
Embodiment
The structural drawing of 4 thrust angular contact formula swivel joints that show according to Fig. 1 is below described as follows: 4 thrust angular contact formula swivel joints, swivel joint fixed body (1) is bolted and is integral with hydraulic rotating clamp, inside has oil returning tube a(8), oil returning tube b(9), two return openings are connected on the oil outlet of solid of rotation (2), oilhole a(10), oilhole b(11) be positioned on solid of rotation (2), when hydraulic fixture clamps, hydraulic oil is by swivel joint oilhole a(10) enter oil pocket, by fixed body (1) oil returning tube a(8) distribute to each hydraulic element, hydraulic oil under input pressure effect in oil circuit is from fixed body (1) oil returning tube b(9) enter in oil pocket, and from oilhole b(11) flow out, when hydraulic fixture unclamps, when swivel joint oil circuit moves towards with clamping, oil circuit trend is contrary, be that hydraulic oil enters oilhole b(11) flow to oil returning tube b(9), oil return is from oil returning tube a(8) flow to oilhole a(10), in fixed body (1), between solid of rotation (2), O type circle (3) and seal ring (4) are housed, fixed body (1) is dynamic sealing with Sealing, in oil-feed and fuel-displaced handoff procedure, can produce impact force, therefore described seal ring (4) adopts teflon seal ring design, O type circle (3) is O type rubber seal, teflon seal ring and O type rubber seal are used in conjunction with, this structure is that to take O type rubber seal be elastomer, teflon seal ring is seal, in this combination, O type circle (3) is as being subject to compressive strain after seal ring pressure after elastomer assembling, produce reaction force simultaneously and make seal ring (3) and fixed body (1) close contact, thereby reach, oil circuit is sealed, after the long-time use of swivel joint, seal ring (4) can produce wearing and tearing, wearing and tearing can cause sealing load between seal ring (4) and fixed body (1) to produce and leak not, O type circle (3) coordinates with seal ring (4) as elastomer compressive strain, can discharge the sealing load that elasticity can be covered the loss to the seal ring (4) after wearing and tearing, thereby keep the sealing of oil circuit, 4 angular contact thrust ball bearings (5) are arranged between fixed body (1) and solid of rotation (2), radial ball bearing (6) is arranged on the thin axle in fixed body (1) rear end, utilize end cap (7) location and compress, due to the swivel joint project organization that adopts 4 angular contact thrust ball bearings (5) to coordinate with radial ball bearing (6), 4 angular contact thrust ball bearings (5) bear whole thrust loads that solid of rotation (2) is input to fixed body (1) axial direction, by being used in combination with radial bearing, make swivel joint in working room, preserve the stability of axis rotation.
Claims (3)
1. 4 thrust angular contact formula swivel joints, it is characterized in that: swivel joint fixed body and hydraulic rotating clamp are bolted and are integral, inside has oil returning tube a, oil returning tube b, two return openings are connected on the oil outlet of solid of rotation, oilhole A, oilhole B are positioned on solid of rotation, mounting O-shaped rings and seal ring between fixed body and solid of rotation, 4 angular contact thrust ball bearings are arranged on the end of fixed body, by end cap, compressed, radial ball bearing is arranged on the thin axle of fixed body, by end cap location and compression.
