Description
Technical field
This utility model relates to well dynamic technical field of tools, particularly to a kind of fancy ten thousand being applicable to helicoid hydraulic motor
To axle.
Background technology
Universal drive shaft is the important component part of helicoid hydraulic motor, uses ball-type universal drive shafts and scratches axle universal drive shaft more.Wherein, axle is scratched
Universal drive shaft lasts a long time, but cannot be used for the helicoid hydraulic motor that camber is bigger, and price is higher simultaneously；Spherical universal axle uses spherical
Key transmission, service life is longer, is most widely used universal, but after using more than certain time simultaneously, spherical universal axle interior
Portion's parts depreciation is more serious, and sealing property is deteriorated, and mud can enter in joint, and then accelerates its rate of wear, causes rubber
Parts against wear.The now application of the low rotation speed large torque motor of helicoid hydraulic motor is to the operation torque of articulated joint for screw drilling rod and use
Life-span has higher requirement.
Summary of the invention
For the problems referred to above, the purpose of this utility model is just to provide a kind of fancy universal drive shaft being applicable to helicoid hydraulic motor,
Its running part uses the tooth of petal shape to be engaged transmission, and mate contact area is big, can transmit bigger moment of torsion, and
And mate is positioned in annular seal space, completely cut off drilling fluid, improve service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fancy universal drive shaft being applicable to helicoid hydraulic motor, including respectively with the motor rotor of helicoid hydraulic motor and power transmission shaft even
Connect two live hinge and the connecting rods that two work are hinged, the two ends of described connecting rod are expanded and become petal tooth, the flower of connecting rod
Lobed tooth, is embedded in two ends respectively and lives in the lobed groove cutting with scissors endoporus；Live in cutting with scissors in endoporus and be respectively mounted dimple, connecting rod two ends in two ends
Inlaying projection seat, the convex spherical of projection seat fits with the concave spherical surface of dimple；The support ring being split into two halves is enclosed within the thin neck of connecting rod, rubber
Gum cover one end is enclosed within the annular groove of support ring, and the other end is enclosed within the thin neck of connecting rod；Gland compresses rubber sleeve；Rubber sleeve passes through larynx
Hoop is tightened on connecting rod.
Further, being threaded in of described gland is lived on hinge endoporus.
Further, it is filled with grease between described connecting rod and hinge alive.
Further, described universal drive shaft two-end structure is symmetrical.
The fancy universal drive shaft being applicable to helicoid hydraulic motor described in the utility model having the beneficial effect that compared to existing technology
1, the fancy universal drive shaft being applicable to helicoid hydraulic motor described in the utility model, its running part uses petal shape
Tooth carries out grinding tooth transmission, and grinding tooth part contact surface is long-pending big, can transmit bigger moment of torsion；
2, the fancy universal drive shaft being applicable to helicoid hydraulic motor described in the utility model, mate is positioned in annular seal space, every
Drilling fluid, improves its service life absolutely.
With detailed description of the invention, milling formula fishing socket described in the utility model is carried out further below in conjunction with the accompanying drawings
Very thin description.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fancy universal drive shaft being applicable to helicoid hydraulic motor described in the utility model；

Description of reference numerals is as follows:
1 lives cuts with scissors；2 dimples；3 projection seats；4 connecting rods；5 rubber sleeves；6 support rings；7 glands； 8—
Larynx hoop.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of fancy universal drive shaft being applicable to helicoid hydraulic motor that present embodiment provides, its effect is
The planetary motion of motor is changed into the fixed-axis rotation of power transmission shaft, and the moment of torsion produced by motor and rotating speed pass to power transmission shaft to boring
Head.Described fancy universal drive shaft includes two hinges 1 alive being connected respectively with the motor rotor of helicoid hydraulic motor and power transmission shaft and by two
The connecting rod 4 of hinge of living 1 connection, the two ends of described connecting rod 4 are expanded and become petal tooth, the petal tooth of connecting rod 4, being embedded in respectively
Live in the lobed groove cutting with scissors 1 endoporus in two ends；Living in cutting with scissors in 1 endoporus and be respectively mounted dimple 2 in two ends, projection seat 3 is inlayed at connecting rod 4 two ends, convex
The seat convex spherical of 3 fits with the concave spherical surface of dimple 2；The support ring 6 being split into two halves is enclosed within the thin neck of connecting rod 4, rubber sleeve 5 one
End is enclosed within the annular groove of support ring 6, and the other end is enclosed within the thin neck of connecting rod 4；Gland 7 compresses rubber sleeve 5；Rubber sleeve 5 passes through larynx
Hoop 8 is tightened on connecting rod 4.
Further, being threaded in of described gland 7 is lived on hinge 1 endoporus.
Further, it is filled with grease between described connecting rod 4 and hinge 1 alive.
Further, described universal drive shaft two-end structure is symmetrical.
Below it is only to realize a kind of method of the present utility model, other ways of realization also Ying Ben based on this structural principle
Within the scope of invention.
