Description
Technical field
This utility model relates to oil drilling cementing technology field, particularly relates to a kind of double containment closed everything axle.
Background technology
At present, the helicoid hydraulic motor used in the drilling engineering of petroleum gas, is to provide power with slush pump, mud is medium, enters in screw motor, and the motion mode of motor is off motion, in order to eccentric motion is changed into dead axle motion, we add universal drive shaft between power transmission shaft and motor.General universal drive shaft goalpost list seals structure, and connecting rod is open architecture, and this structure is with oils and fats as lubricant, and it is internal that sealing sheath stops mud to enter strand of living, and it is smooth and easy, without jam phenomenon that open architecture makes universal drive shaft swing.But owing to, in drilling process, universal drive shaft amplitude of fluctuation is excessive, sealing shroud larynx hoop lost efficacy and came off or the unexpected breakage of rubber sheath, causes strand seal failure of living, causes inter deterioration to increase, and service life reduces；Taking off post in open architecture has axial sliding friction and friction displacement big with strand of living, open type connecting rod respectively, and the rate of wear is very fast, and the inefficacy that makes to take off post cannot play transmission moment of torsion.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of double containment closed everything axle, improves sealing effectiveness, improves the service life taken off post.
This utility model for achieving the above object, by the following technical solutions:
A kind of double containment closed everything axle, it is characterised in that: including closed link, the two ends up and down of described closed link are connected to the everything joint that structure is identical；Described everything joint include living strand, lock sleeve, trim ring, ball seat, take off post, bulb, fixed larynx hoop, sealing shroud and rectangular seal；Described ball seat is fixed on the intracavity bottom of described strand of living, described bulb coordinates with described ball seat, described bulb is fixed on the top of described closed link, and the end loops week of described closed link is provided with rolling groove, described in take off post be arranged on described rolling groove and described live strand inner chamber between；Described rectangular seal is arranged between described rolling groove and described inner chamber, is fixed by described trim ring bottom rectangular seal, and described lock sleeve is threadeded with described strand of living, and bottom lock sleeve is fixed on the positioning described trim ring and rectangular seal；One end of described sealing shroud is fixed on described living in strand by described fixed larynx hoop, and the other end of sealing shroud is connected between described lock sleeve and described trim ring.
Preferably, described sealing shroud is horn-like.
The beneficial effects of the utility model are: compared with prior art, and this utility model simple in construction is prone to processing, assembling, member replacing is convenient, service life is long, and production cost is low.In the structure of double containment enclosed goalpost universal drive shaft, rectangular seal avoids because rubber sheath is unexpected damaged, seal failure causes strand internal entrance mud of living, accelerate to live and twist the abrasion of each parts in inside, being allowed to the life-span is greatly decreased, closed link structure makes the axial internal clearance taken off post reduce, and then decreases strand of living, takes off post and axially wearing and tearing between connecting rod, and the service life making universal drive shaft overall is improved, avoid because of cardan shaft failure, cause unnecessary trip-out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail detailed description of the invention of the present utility model.As it is shown in figure 1, a kind of double containment closed everything axle, including closed link 1, the two ends up and down of described closed link are connected to the everything joint 2 that structure is identical；Described everything joint includes strand 3, lock sleeve 4, trim ring 5, ball seat 6 alive, take off post 7, bulb 8, fixed larynx hoop 9, sealing shroud 10 and rectangular seal 11；Described ball seat is fixed on the intracavity bottom of described strand of living, described bulb coordinates with described ball seat, described bulb is fixed on the top of described closed link, and the end loops week of described closed link is provided with rolling groove, described in take off post be arranged on described rolling groove and described live strand inner chamber between；Described rectangular seal is arranged between described rolling groove and described inner chamber, is fixed by described trim ring bottom rectangular seal, and described lock sleeve is threadeded with described strand of living, and bottom lock sleeve is fixed on the positioning described trim ring and rectangular seal；One end of described sealing shroud is fixed on described living in strand by described fixed larynx hoop, and the other end of sealing shroud is connected between described lock sleeve and described trim ring.Described sealing shroud is horn-like.
Ball seat is put in the inner chamber of strand of living after smearing grease, one end of closed link is sequentially placed into lock sleeve, rubber sealing boot, trim ring and rectangular seal, grease is smeared on rectangular seal, take off post and smear grease and put into the blind groove of interlinking lever end, bulb inserts in the hole of connecting rod end face, tightens rubber sleeve with fixed larynx band, and lock sleeve is connected with strand of living, screw thread smears anaerobic adhesive, and closed link other end dress method is the most identical.
This utility model simple in construction is prone to processing, assembling, member replacing is convenient, service life is long, and production cost is low.In the structure of double containment enclosed goalpost universal drive shaft, rectangular seal avoids because rubber sheath is unexpected damaged, seal failure causes strand internal entrance mud of living, accelerate to live and twist the abrasion of each parts in inside, being allowed to the life-span is greatly decreased, closed link structure makes the axial internal clearance taken off post reduce, and then decreases strand of living, takes off post and axially wearing and tearing between connecting rod, and the service life making universal drive shaft overall is improved, avoid because of cardan shaft failure, cause unnecessary trip-out.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
