Abstract
The invention relates to an exciting motor, in particular to an exciting force adjusting structure of an exciting motor of a vibrating screen. The exciting force adjusting structure of the exciting motor of the vibrating screen comprises a driving eccentric block. The driving eccentric block is fixed to a rotary shaft of the motor. An arc-shaped sliding groove is formed in the driving eccentric block. A plurality of counter bores are formed in the arc-shaped sliding groove. An adjusting eccentric block is arranged outside the driving eccentric block. The rotary shaft of the motor is sleeved with the adjusting eccentric block through a bearing. A threaded hole is formed in the adjusting eccentric block. Part of a round guiding pin is provided with a thread. The round guiding pin penetrates through the threaded hole, and the front end of the round guiding pin is located in the arc-shaped sliding groove. The round guiding pin can be rotated to be inserted into the counter bores. The exciting force adjusting structure is simple and convenient to adjust; two different kinds of exciting force can be generated when the exciting motor rotates in the positive direction and in the negative direction, two different motion trails of the vibrating screen can be achieved, and the requirements for slurry under various working conditions are met.
Description
Technical field
The present invention relates to a kind of shock electric machine, particularly relate to vibrosieve shock electric machine exciting force adjustment structure.
Background technology
In Process of Oil Well Drilling, it is necessary to use drilling fluid vibrating sieve (abbreviation bore screen) that mud is processed, in order to mud can recycle again, and shock electric machine is to realize in this process of paramount importance one; What set in existing shock electric machine is all fixing sliding shoe, and its exciting force is fixing, nonadjustable, it is impossible to enough adapt to the mud of the various operating mode in down-hole.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, can quickly adjust the size of exciting force, to adapt to the vibrosieve shock electric machine exciting force adjustment structure of the mud of various operating mode.
The technical scheme is that
Vibrosieve shock electric machine exciting force adjustment structure, including driving eccentric block, described driving eccentric block is fixed on machine shaft, eccentric block is driven to have arc chute, some counterbores are had in arc chute, drive eccentric block arranged outside eccentric adjustment block, eccentric adjustment block passes through bearing holder (housing, cover) on machine shaft, eccentric adjustment block has screwed hole, guiding round pin one is threaded, guiding round pin is through screwed hole, and the front end of guiding round pin is positioned at arc chute, and rotary steering round pin can make guiding round pin insert in counterbore.

1 drives eccentric block 2 eccentric adjustment block 3 machine shaft 4 arc chute 5 to lead in the fixing nut 10 of round pin 6 nut 7 Magnet 8 layer of polyurethane 9 diameter of axle six axial back-up ring 14 limiting plates of square bolt 13 in six side's holding screw 11 oilless bearings 12.
Detailed description of the invention
Vibrosieve shock electric machine exciting force adjustment structure, including driving eccentric block 1, described driving eccentric block 1 is fixed on machine shaft 3 by flat key and interior six square bolts 12, eccentric block 1 is driven to have arc chute 4, some counterbores are had in arc chute 4, drive eccentric block 1 arranged outside eccentric adjustment block 2, eccentric adjustment block 2 is enclosed within machine shaft 3 by oilless bearing 11, machine shaft 3 is also cased with the fixing nut 9 of the diameter of axle, the fixing nut 9 of the diameter of axle is outside oilless bearing 11, the fixing nut 9 of the diameter of axle is fixed on machine shaft 3 by interior six side's holding screws 10, machine shaft 3 outer end arranges axial back-up ring 13.
On eccentric adjustment block 2, processing has screwed hole, thin nut 6 is set outside screwed hole, guiding round pin 5 one is threaded, guiding round pin 5 traverse screwed hole and thin nut 6, the front end of guiding round pin 5 is positioned at arc chute 4, rotary steering round pin 5 can make guiding round pin 5 insert in counterbore, guiding round pin 5 is made up of 35CrMo, the front portion of guiding round pin 5 is coated with layer of polyurethane 8, layer of polyurethane 8 effect is buffering collision of closed, reduce the noise driving eccentric block 1 and eccentric adjustment block 2 to produce when mutually clashing into, simultaneously work as deformation buffer effect, it is prevented that the deformation of guiding round pin 5.
The end face driving eccentric block 1 arranges limiting plate 14; the end face of eccentric adjustment block 2 arranges Magnet 7; rely on when shutting down magnetic force drivings eccentric block 1 inhaled with eccentric adjustment block 2 together be rotated in deceleration, reach the noise that both reducing, collision and then reduction produce each other mutually.
The present invention can make vibrosieve realize two kinds of motor patterns, a kind of single-track motor pattern, a kind of dual trace motor pattern.
When single-track motor pattern is execute-in-place, shock electric machine only produces a kind of identical exciting force when rotating, makes vibrosieve realize single movement locus; This pattern is that the front end being directed to round pin 5 enters a counterbore according to required sharp power so that drive eccentric block 1 and eccentric adjustment block 2 to be integrally forming, it is achieved drives eccentric block 1 and eccentric adjustment block 2 to stagger and forms the required angle swashing power, reaches this motor pattern.
When dual trace aeb mode formula is execute-in-place, shock electric machine can produce exciting force two kinds different when rotating, makes vibrosieve realize movement locus two kinds different. This pattern is to screw out to be contained on eccentric adjustment block 2 guiding round pin 5, makes the eccentric adjustment block 2 with guiding round pin 5 can slip in the arc chute 4 driving eccentric block 1; When motor axially turns clockwise, actively eccentric block first rotates as active block, driven eccentric block is not driven by motor shaft because coupling motor shaft by oilless bearing 11, circular arc slideway is by the round pin 5 that leads, once be slid onto ways-end, drive eccentric block 1 eccentric adjustment block 2 will be driven to rotate together by the round pin 5 that leads, and now drive eccentric block 1 and eccentric adjustment block 2 shape to have angle, and the radial direction angle being sized for circular arc slideway two edges and machine shaft 3 center of angle, meanwhile create the exciting force under this state, it is achieved a kind of movement locus; When motor axially rotates counterclockwise, driving eccentric block 1 first to rotate as active block, just there is not sliding in circular arc slideway, drives eccentric block 1 eccentric adjustment block 2 will be driven to rotate together by the round pin 5 that leads. And now driving eccentric block 1 and eccentric adjustment block 2 angle is zero, produce maximum exciting force in this condition, it is achieved another movement locus.
Finally should be noted that: above example is only in order to illustrate that technical scheme is not intended to limit; Although the present invention being described in detail with reference to preferred embodiment, those of ordinary skill in the field are it is understood that still can modify to the specific embodiment of the present invention or portion of techniques feature carries out equivalent replacement; Without deviating from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention is claimed.
