Description
Technical field
The present invention relates to helicoid hydraulic motor technical field, particularly relate to the split type universal drive shaft assembly of a kind of helicoid hydraulic motor.
Background technology
At present, the helicoid hydraulic motor used in the drilling engineering of oil, natural gas, the object of its universal drive shaft is exactly the dead axle motion eccentric motion of motor rotor being converted to power transmission shaft.The form of structure of general universal drive shaft is divided into two kinds, a kind of petal type, a kind of ball shape structure at present.The structure of petal type is simple (movable joint-connecting rod-movable joint composition), and completely by drilling fluid erosion, the life-span is shorter.Ball shape structure groundwork position is protected by sealing shroud, connecting rod be structure as a whole renewal part time need whole more conversion materials to cause waste, by spacial influence in ting model screw rod, assembling is inconvenient.In addition, conventional universal drive shaft inner seal structure is sealing shroud, is fixed on connecting rod by larynx hoop, and this result is cumbersome in assembling, and fixing bad, can in use cause hermetically-sealed construction ineffective, universal drive shaft premature failure.
Summary of the invention
Main purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides a kind of helicoid hydraulic motor split type universal drive shaft assembly.Improve universal drive shaft application life, it is convenient to assemble, good airproof performance.
The present invention for achieving the above object, by the following technical solutions: the split type universal drive shaft assembly of a kind of helicoid hydraulic motor, it is characterized in that: comprise live strand, left lock sleeve, right lock sleeve, left connecting rod, right connecting rod, adapter sleeve, water cap, described left and right connecting rod is linked together by described adapter sleeve, the end of left connecting rod and described work are provided with left roller slot between twisting, in described left roller slot, the post that rolls left is housed, the described post that rolls left is wrapped in described living between strand and left connecting rod by described left lock sleeve, between described left lock sleeve and described left connecting rod, O RunddichtringO is housed; Be provided with right roller slot between the end of right connecting rod and described water cap, in described right roller slot, right roller be housed, described right roller is wrapped between described water cap and right connecting rod by described right lock sleeve, between described right lock sleeve and described right connecting rod, O RunddichtringO is housed.
Preferably, described water cap has and is vertically provided with hydrophthalmia, ensure the water conservancy impact effect in power transmission shaft.
Preferably, described left and right connecting rod and described live twist, water cap linkage section is respectively spherical structure.Eliminate the ball in conventional universal drive shaft and ball seat, the inefficacy that not only avoid between ball and ball seat also saves material.
Preferably, the middle part of described water cap is provided with plug.
Beneficial effect: two connecting rods are linked together by adapter sleeve, moment of torsion can as routine with rotating speed transmission.Water cap there is vertical hydrophthalmia, ensures the water conservancy impact effect in power transmission shaft.Connecting rod and work are twisted, water cap linkage section is spherical structure, and eliminate the ball in conventional universal drive shaft and ball seat, the inefficacy that not only avoid between ball and ball seat also saves material.This structure universal drive shaft not only structure is simple, convenient when assembling, and solves the transmission of moment of torsion and rotating speed under little space; The universal drive shaft of this form combines the advantage of petal type and ball shape structure universal drive shaft in addition, can as petal universal shaft random replacing inoperative component, ensure that the commutativity of part without integral replacing and reduce maintenance cost, but also preserved ball-type universal drive shaft main working parts sealing, ensure that the transmission effect of working life and moment of torsion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.The split type universal drive shaft assembly of a kind of helicoid hydraulic motor, comprise strand 1 alive, left lock sleeve 2, right lock sleeve 3, left connecting rod 4, right connecting rod 5, adapter sleeve 6, water cap 7, described left and right connecting rod is linked together by described adapter sleeve, the end of left connecting rod and described work are provided with left roller slot 8 between twisting, in described left roller slot, the post 9 that rolls left is housed, the described post that rolls left is wrapped in described living between strand and left connecting rod by described left lock sleeve, between described left lock sleeve and described left connecting rod, O RunddichtringO 10 is housed; Right roller slot 11 is provided with between the end of described right connecting rod and described water cap, in described right roller slot, right roller 12 is housed, described right roller is wrapped between described water cap and right connecting rod by described right lock sleeve, between described right lock sleeve and described right connecting rod, O RunddichtringO 13 is housed.
Described water cap has and is vertically provided with hydrophthalmia 14, ensure the water conservancy impact effect in power transmission shaft.Described left and right connecting rod and described work are twisted, water cap linkage section is respectively spherical structure.Eliminate the ball in conventional universal drive shaft and ball seat, the inefficacy that not only avoid between ball and ball seat also saves material.
The middle part of described water cap is provided with plug 15.The same with conventional universal drive shaft, the strand alive of this structure universal drive shaft and water cap are also provided with oil filler point, the lubrication keeping inner goalpost and live between strand, ensure the universal drive shaft life-span at work, in work, the impact of mud, seals with plug, ensure that the environment of its work.
Two connecting rods are linked together by adapter sleeve, and moment of torsion can as routine with rotating speed transmission.Water cap there is vertical hydrophthalmia, ensures the water conservancy impact effect in power transmission shaft.Connecting rod and work are twisted, water cap linkage section is spherical structure, and eliminate the ball in conventional universal drive shaft and ball seat, the inefficacy that not only avoid between ball and ball seat also saves material.This structure universal drive shaft not only structure is simple, convenient when assembling, and solves the transmission of moment of torsion and rotating speed under little space; The universal drive shaft of this form combines the advantage of petal type and ball shape structure universal drive shaft in addition, can as petal universal shaft random replacing inoperative component, ensure that the commutativity of part without integral replacing and reduce maintenance cost, but also preserved ball-type universal drive shaft main working parts sealing, ensure that the transmission effect of working life and moment of torsion.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
