Drilling tool.Enter motor when the mud that slush pump pumps out flows through by-passing valve, certain pressure differential is formed in the import and export of motor, is pushed away
Turn is rotated around the axis of stator, and rotating speed and moment of torsion are passed to drill bit by universal shaft and transmission shaft, so as to fulfill brill
Well operations.Had many advantages using helicoid hydraulic motor probing compared with routinely drilling, as drill rod abrasion significantly declines, rate of penetration
It is high.It is beat directional hole major appliances, the particularly application in directional well, horizontal well technology, in order to improve drilling quality
Important positive effect is played with bit speed, there is indispensable meaning in drilling field.
The service life of conventional screw drilling tool be generally 150 it is small when within, its weak link has very much, wherein universal shaft live
Hinge is threadedly coupled failure etc. with water cap and happens occasionally, and directly results in drilling tool operational failure, seriously affects life of product and drilling well peace
Entirely, it would be highly desirable to solve.
Prior art majority is hinged in connecting rod lower end and work, and hinge living connects water cap, this knot with thread forms again
Structure is cumbersome, and of high cost and security risk point is more.
In consideration of it, the present invention provides a kind of novel conjoined water cap formula universal shaft and helicoid hydraulic motor.
The content of the invention
For above-mentioned majority existing in the prior art it is hinged in connecting rod lower end and work, hinge living is again with thread forms
The problem of structure of connection water cap, this structure is cumbersome, and of high cost and security risk point is more, the present invention provides a kind of Novel connection
Body water cap formula universal shaft and helicoid hydraulic motor.
To achieve the object of the present invention, the present invention provides a kind of novel conjoined water cap formula universal shaft, it is characterised in that bag
Include articulated joint 11, connecting rod 4 and Contiuum type water cap 1 living, 11 upper external screw thread of the articulated joint connection motor living, lower end and connecting rod 4
It is hinged；1 upper end of Contiuum type water cap is hinged with connecting rod 4, and lower end internal thread is connected with transmission shaft.
Preferably, 1 material of Contiuum type water cap is 40CrNiMoA.
Correspondingly, present invention also offers a kind of helicoid hydraulic motor, novel conjoined water cap formula universal shaft described above is used.
Compared with the prior art, beneficial effects of the present invention are, The present invention reduces an articulated joint living, to reduce processing
Cost, optimization remove a threaded connection place, reduce security risk point, so that it is cumbersome to solve prior art construction, it is of high cost
And security risk point it is more the problem of, extend life of product and drilling safety and improve drilling efficiency.
