Function.
Specifically, drilling fluid enters compound speed-raising helicoid hydraulic motor from top connection 1, flow through between stator rubber 4 and rotor 5
Gap between screw when, drive rotor 5 around the axis of stator rubber 4 to do planet gyration movement, torque and revolving speed successively passed downwards
Pass universal shaft 7, upper transmission shaft 8, lower drive shaft 12, drive joint 19 and drainage tray 23, above each part by rotor 5 drive around
Tool axis does revolution at a high speed movement.And by top connection 1, motor case 3, universal shaft housing 6, bearing case 11, transmission shaft outside
Shell 14 and the tool outer casing formed with liquid set 22 do with upper drilling string and slowly run or do not rotate.Due to upper vibrating mass 15 and transmission
Shaft housing 14 is spline connection, and lower vibrating mass 17 with lower drive shaft 12 is that spline is connect, therefore upper vibrating mass 15 and lower vibration
It there are rotational speed difference and can move up and down between block 17, and there are balls in upper 15 lower end surface of vibrating mass and lower 17 upper surface of vibrating mass
Hole, several balls 16 are pressed in centre by upper vibrating mass 15 and lower vibrating mass 17.
When compound speed-raising helicoid hydraulic motor is normally crept into, drill pressure can successively pass to upwards drive joint 19,
Anti- to cap off 18, lower vibrating mass 17, ball 16, upper vibrating mass 15, disc spring 13 and upper transmission shaft 8, the above part is by axial compression, axis
Bearing group 10, bearing block 9, each part of upper transmission shaft 8 and lower part have been carried out axial limiting by the interior step for holding shell 11.It is normal to bore
Into when, lower drive shaft 12 drives lower vibrating mass 17 to do revolution at a high speed movement, due to ball 16 by axial compression in ball hole, and on
There are rotational speed differences between vibrating mass 15 and lower vibrating mass 17, therefore the lower vibrating mass 17 of revolution at a high speed will lead to ball 16 and rotate out
Ball hole, and upper vibrating mass 15 is jacked up upwards, energy is compressed and put aside to disc spring 13, when ball 16 returns in ball hole, disc spring 13
The energy of savings can be released, and upper vibrating mass 15 can impact downwards lower vibrating mass 17, with the revolution at a high speed of lower drive shaft 12, axis
It can be passed down to drill bit incessantly to vibrational energy.It is the working principle of axial vibration mechanism above, it can be achieved that axial vibration
Dynamic function.
It is done with liquid set 22 with tool outer casing and slowly runs or do not rotate, the outer drainage hole for being with arc at two, lower part has
Four radial nozzles.Drainage tray 23 does revolution at a high speed movement with drive joint 19, there is axially extending bore everywhere thereon.Drive joint
Two a chambers and two b chambers are divided by pendulum 24 inside 19, the axially extending bore everywhere on drainage tray 23 respectively with four chamber phases
Connection.There are four radial nozzles on the cylindrical surface of pendulum 24.There are four spray-holes for 19 inside of drive joint.Wherein, drive joint
The angle of four spray-holes on 19, the angle with four radial nozzles on liquid set 22, axially leading on drainage tray 23 everywhere
The angle in hole and the angle of four radial nozzles on pendulum 24 are all identical.
For drilling fluid after 12 central passage stream of lower drive shaft, a part flows to shaft bottom, and another part passes through drive joint 19
Four spray-holes radially enclose injection, only when four spray-holes simultaneously with on liquid set 22 four radial nozzles,
When four radial nozzles on pendulum 24 are connected, 24 ability quick rotation of pendulum simultaneously taps drive joint 19, while a chamber or b
Intracavitary liquid then the axially extending bore everywhere on drainage tray 23 and with liquid set 22 on two at arc drainage hole work is discharged upwards
Tool flows to bore hole annulus gap, such as D-D sectional view, expression be pendulum 24 two dead-centre positions, a chamber is opened and b chamber is closed,
B chamber is opened and a chamber is closed, two kinds of working conditions, can percussion vibration drive joint 19, it is uninterrupted to form circumferential impact vibration energy
Amount, and drill bit is passed to by drive joint 19.It is the working principle of rotational vibration mechanism above, it can be achieved that rotational vibration function.
Therefore, it with the compound speed-raising helicoid hydraulic motor of axial vibration and rotational vibration function, can be provided for drill bit substantially
Torque and revolving speed, and axial vibration and rotational vibration function can be added.
In conclusion the contents of the present invention are not limited in the above embodiments, the knowledgeable people in same area can
Can propose other embodiments easily within technological guidance's thought of the invention, but this embodiment is included in this hair
Within the scope of bright.
