Description
Technical field
This utility model is related to oil drilling cementing technology field, more particularly to a kind of petal type ball-type universal drive shaft.
Background technology
At present, the helicoid hydraulic motor used in the drilling engineering of petroleum gas, is to provide power with slush pump, and mud is
Medium, in screw motor, and the motion mode of motor is eccentric 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 is six goalpost formula universal drive shafts, and connecting rod is six balls with strand living
Slot type structure, this structure are that, with oils and fatss as lubricant, sealing sheath prevents mud from entering strand inside living, and six ball slot type structures make ten thousand
Swing smooth to axle, without jam phenomenon.But as, in drilling process, universal drive shaft amplitude of fluctuation is excessive, six ball groove formula connecting rods knot
Structure intensity is not high, and rod deformation is easily caused in the case of long-time, and six ball groove formulas are lived and twisted as cell wall is excessively thin, in the case of high pulling torque
Easily there is " roller " phenomenon, it is impossible to which transmitting torque, service life are reduced.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of petal type ball-type universal drive shaft, is resisted
Turn round intensity to be strengthened, contact area increases, service life is improved.
This utility model for achieving the above object, is employed the following technical solutions：
A kind of petal type ball-type universal drive shaft, it is characterised in that：Including the top connection of structure identical and lower contact, it is described on connect
Connected by connecting rod between head and lower contact, the top connection and lower contact include petal type work strand, ball seat, bulb, pressure respectively
Circle, lock sleeve, rubber sleeve, petal type connecting rod, larynx hoop and steel ball；The ball seat is fixed on the inner chamber that the petal type work is twisted
In, the bulb is arranged on the front end of the petal type connecting rod, and bulb is coordinated with the ball seat, and steel ball is arranged on the petal type
In the ball groove of connecting rod sidepiece；The trim ring is enclosed within the petal type connecting rod, the top of rubber sleeve be enclosed within the trim ring it is outer and by
The lock sleeve is fixed, and locking external threading and the petal type are lived in twisting and be threadedly coupled, and the larynx hoop is by the rubber sleeve
Bottom is fixed on the petal type connecting rod.
Preferably, be provided with three petal type grooves in the living inner chamber for twisting, the petal type connecting rod be provided with it is described
The petal type boss of petal type groove fit.
The beneficial effects of the utility model are:Compared with prior art, this architecture it is simple it is easy to process, assemble, match somebody with somebody
Part changes convenient, long service life, low production cost.In petal type ball-type universal drive shaft, connecting rod end face petal design is abundant, antitorque
Strengthen, be unlikely to deform, petal type is lived and twists internal structure compared with tradition strand living, simple structure and torsional strength increases, it is living twist with
The contact area of connecting rod increases, and wear-resisting enhancing, service life are improved.The service life for making universal drive shaft overall is improved,
Avoid because of cardan shaft failure, cause unnecessary trip-out.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the interior shape figure of petal type work strand in this utility model；
Fig. 3 is the sectional view of petal type connecting rod in this utility model；
Fig. 4 is the axonometric drawing of petal type connecting rod in this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1-Fig. 4 institutes
Show, a kind of petal type ball-type universal drive shaft, including the top connection of structure identical and lower contact, lead between the top connection and lower contact
Connecting rod connection is crossed, the top connection and lower contact include that petal type is lived respectively and twist 1, ball seat 2, bulb 3, trim ring 4, lock sleeve 5, rubber
Gum cover 6, petal type connecting rod 7, larynx hoop 8 and steel ball 9；The ball seat is fixed on the petal type and lives in the inner chamber for twisting, the ball
Head is arranged on the front end of the petal type connecting rod, and bulb is coordinated with the ball seat, and steel ball is arranged on the petal type connecting rod sidepiece
Ball groove in；The trim ring is enclosed within the petal type connecting rod, and the top of rubber sleeve is enclosed within outside the trim ring and by the locking
Set is fixed, and the locking external threading is lived in twisting with the petal type and is threadedly coupled, and the bottom of the rubber sleeve is fixed by the larynx hoop
On the petal type connecting rod.Be provided with three petal type grooves in the living inner chamber for twisting, the petal type connecting rod be provided with
The petal type boss of the petal type groove fit.
During installation, the ball seat is put into petal type and lives in I inner chamber of strand after smearing grease, one end of the petal type connecting rod
Lock sleeve I, rubber sealing boot, trim ring and steel ball are sequentially placed into, grease on steel ball, is smeared, the ball groove of petal type connecting rod is placed on
In, in the hole of the bulb insertion petal type connecting rod end face, rubber sleeve is tightened with fixed larynx band, lock sleeve I twists I company with living
Connect, screw thread smears anaerobic adhesive, connecting rod other end dress method is identical therewith.
This architecture is simply easy to process, assemble, member replacing is convenient, long service life, low production cost.Petal type
In ball-type universal drive shaft, connecting rod end face petal design is abundant, and antitorque reinforcement is unlikely to deform, and petal type is lived and twists internal structure with tradition work
Strand is compared, and the contact area of simple structure and torsional strength increase, strand living and connecting rod increases, and wear-resisting enhancing, service life are obtained
Improve.The service life for making universal drive shaft overall is improved, it is to avoid because of cardan shaft failure, causes unnecessary trip-out.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
