Specific implementation mode
Following further describes the present invention with reference to the drawings：
In conjunction with shown in Fig. 1-Fig. 7, this fluid power-Magnetic drive borehole cleaning tool overload decoupled device by input terminal connector 1,
Overload action body 2, output end connector are sleeved on outside shaft 4 and constitute successively, and output end connector is connect with when work with magnetic axis,
Therefore also referred to as magnetic axis connector 3, input terminal connector 1, overload action body 2, the outer diameter of output end connector three are equal, can be same
The heart is matched with tool housing inner edge.4 left end of shaft, which is connected with input terminal connector 1 by bearing 10, to be not only fitted close, but also is being passed
Interference is not mutually generated in dynamic.4 right end of shaft, by screw connection, ensures the two synchronous rotary with output end connector.Overload
Action body（Shell fragment groove）2 between two connectors can radial free movement, only by transmitting torque influence.
Refering to fig. 1, Fig. 2, input terminal connector 1 is integrally formed by inserting side cooperating teeth 12 with axial engagement flange 11, defeated
It is to insert side cooperating teeth 12 to enter to hold connector 1, inserts side cooperating teeth 12 and is mutually tied with side cooperation tooth socket is held in fluid power reforming unit and magnetic axis
It closes, composition socket joint connection.Socket joint connection upper to greatest extent can save radial space, realize connector compared to flanged joint
Outer edge radius is harmonious with shell inner edge；Compared to threaded connection, it can be achieved that radial be seamlessly connected, tool axial length is reduced.It should
Bindiny mechanism is simple in structure, is easily installed and dismantles.1 other end of input terminal connector is axial engagement flange 11, ring flange
It is ball 9 outside, ball 9 connects radial engaging tooth, and the connector other end is axial engagement flange 11, ring flange rotation, engagement
Tooth drives shaft rotation by ball 9, transmits torque, completes the input of power end torque.In this transmission, it can be rolled by changing
9 diameter of pearl and quantity, outer edge radius in variation tool.Connector inner edge is connected by bearing 10 with shaft 10, and bearing 10 plays branch
The effect of support and reducing friction resistance.The mounting means that bearing 10 uses is bilateral tight fit.
9 usage quantity of ball is related with cylindrical body inner edge radius（Outer edge radius is fixed）, inner edge radius is bigger, ball bearing radius
About small, usage quantity is more.
Refering to Fig. 3, overload action body 2 is bilateral circular ring structure, and side is spherical groove（That is ball engagement face 13）, surface
It is smooth, it is matched with ball；The other side is cylindrical groove (i.e. spring leaf mating surface 14), is matched with disc spring film.Overload acts
Body 2 is limited 9 position of ball by 7 radial compression applied of spring leaf.
Refering to Fig. 5, Fig. 6, Fig. 7, shaft 4 is cylindrical body, and shaft 4 is integrally formed with radial tooth-like engaging mechanism 8, shaft 4
One end is connected with input terminal connector 1 by bearing 4, axial engagement flange 11, radial tooth-like engaging mechanism 8, spherical groove
Ball chamber is collectively formed, several balls are distributed in ball intracavitary, and each ball is located at the engaging tooth of radial tooth-like engaging mechanism 8
In groove, the number of teeth is consistent with 9 quantity of ball.Engaging tooth radial width is that ball diameter engages the sum of tooth height, ball 9 with axial
It can axially move in tooth socket.Shaft 4 is equipped with screw thread, and disc spring film, spring leaf ligand 5, adjusting nut 6 are set with successively
Thereon, disc spring film 7 is located in cylindrical groove for cooperation.Shaft 4 is equipped with magnetic axis side mounting hole 16, and output end connector also has
Shaft matching hole 15, shaft 4 are bolted to connection with output end connector.
Under normal operating conditions, fluid power pressure difference blade input power drives the rotation of input terminal connector, ball to be located at flange
Dish axle makes shaft synchronous rotary into engaging tooth groove, by the transmission of no backlash torque, is finally driven via input terminal connector 1
Magnetic axis rotates, and completes torque and transmits.
Under abnormal operation, magnetic axis is motionless because of retardance so that decoupled device transmits torque and increases, and ball is because by radial direction
Pressure is loaded more than spring leaf, and compression spring leaf 7, ball 9 is detached from axial engaging tooth groove, and input terminal connector 1 is beaten with shaft 4
Sliding to disconnect, input terminal connector 1 is released with output end connector and is connected, and it is decoupled to complete overload.
Radial tooth-like 8 engaging tooth tooth socket part of engaging mechanism, 11 engaging tooth tooth socket part of axial engagement flange are all made of
High-strength alloy, surface are heat-treated, and ensure that transmission is smooth, and can prolong the service life.
Shaft 4 is integrally machined by blank, without any through-hole, it is ensured that cleaner for high-pressure drilling fluid in internal flow not
Thorn leakage shell, causes tool to destroy.
Refering to Fig. 8, the principle that overload protection can be achieved in the present invention is：Mapping is under normal operating conditions, and torque transmission is shown
It is intended to.Under certain restrictions torque, ball 9 is located in radial engagement tooth socket, and 9 directions stress F of ball can be analyzed to radial direction as schemed
Power FXAnd axial force FY, radial load because by overload action body blocking due to be cancelled, ball 9 does circle only by responsive to axial force
Zhou Yundong drives shaft rotation to complete torque and is transmitted in input/output terminal.When blade chance card does not rotate, torque increases, and is more than bullet
The 7 stress limit of reed, ball 9 are detached from groove, and overload action body 2 is changed to such as right figure position, and the movement of ball 9 does not turn by ring flange
It is dynamic to influence, it skids and is detached from, input terminal idle running unloading.After blade restores rotation, torque declines, and ball 9 returns ring flange, connects again
It connects and completes torque transmission.
Overload action body 2 can act in two connectors, when minimum movements amount, the heart position in the grooves of ball 9, and action
Body one end, is close to ring flange；When maximum actuation amount, ball 9 is just detached from tooth socket, and the action body other end is close to output end connection
Body.
Adjusting nut 6 can play the role of regulating device maximum transmitted torque, pass through 7 pine of rotating nut adjustment spring piece
Tight degree changes initial value axial compressive force, and then can play the role of changing maximum delivered torque.
The present invention devises a kind of fluid power-decoupled device of Magnetic drive borehole cleaning tool overload, when permanent magnetism blade is in ring
When sky is stopped operating by external force, fluid power rotary magnetic core and permanent magnetism blade can be made automatically decoupled.
