Technical field
The utility model relates to a kind of control device, more particularly, relates to a kind of magnetic torque control device.
Background technology
The existing mechanical transmission generally realizes by rigidly connected drive disk assembly, thereby has shortcomings such as mechanical friction, wearing and tearing, fragile drive disk assembly, efficient are low, inconvenient operation.
Afterwards, various magnetic drivers have appearred on the market, for example, " magnetic driver " of Chinese patent CN2757421Y bulletin, this magnetic driver comprises prime mover, prime mover is provided with driving shaft, be fixed with main magnet on the described driving shaft, the position corresponding with main magnet is provided with from magnet, is fixed on the output shaft from magnet, and driving shaft and output shaft are by main magnet and from the magnetic force induction transmission between the magnet; This magnetic driver relies on magnetic drives that prime mover is connected with the mechanism loading contactless transmission, reduced power transmission loss, improved transmission efficiency, when the resistance of mechanism loading during greater than the driving force of magnetic force, prime mover just can overcome the driving force of magnetic force and produce idle running, make prime mover and mechanism loading can because of the overload etc. former thereby the damage.Simultaneously, driving shaft or output shaft are provided with reduction gearing, and the gear that is connected with magnet in the reduction gearing is a carrier wheel, by carrier wheel scalable master's magnet with from the distance between the magnet, make output torque, the power of prime mover, moment of torsion, power and the rotating speed of the corresponding generation of mechanism loading change, thereby have clutch action.But because this magnetic driver is regulated main magnet by carrier wheel and from the distance between the magnet, and the adjusting of carrier wheel is wayward, so its adjusting is very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of magnetic torque control device easy to adjust.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of magnetic torque control device, comprise power shaft and output shaft, power shaft and output shaft are separated and are in coaxial position, main magnet is installed on the power shaft, be equipped with on the output shaft from magnet, main magnet with from the mutual magnetic attraction of magnet and contactless transmission is connected, it is characterized in that: be provided with a governor motion between power shaft and the output shaft.
Described governor motion comprises regulates overcoat and holder, regulating overcoat can be enclosed within on the power shaft around power shaft with rotating, holder is fixedlyed connected with output shaft, regulates overcoat and holder by being threaded, and the junction of regulating overcoat and holder is provided with a lock screw; Regulate outer putting and be provided with an annular groove, be positioned at above-mentioned annular groove, be installed with a fixed head on the annular groove from magnet; Main magnet is fixedly mounted on the output shaft by a mount pad, and main magnet is with corresponding from magnet.Because, regulate overcoat and holder by being threaded, holder is fixedlyed connected with output shaft, and is positioned at the annular groove of adjusting overcoat from magnet, so, can be regarded as from magnet and to be installed on the output shaft.
As preferred structure of the present utility model, described adjusting puts outward and is provided with internal thread, and holder is provided with external screw thread, and the internal thread that puts outside regulating is connected with the external screw thread on the holder.Like this, can prevent from adjustment process, to produce skew, thereby guarantee the coaxial position of power shaft and output shaft because of helicitic texture makes the coaxial position of power shaft and output shaft.
Described main magnet and can be annular high strong magnet from magnet, main magnet is corresponding with the position from magnet, and both opposite sex are relatively; Described main magnet and also can be that one of them is annular high strong magnet from magnet, another is annular sensor magnet, both positions are corresponding.
In order to make magnetic drives not be subjected to external influence, described adjusting puts outward and is provided with a cavity, and above-mentioned main magnet is positioned at this cavity, and the upper end of cavity is provided with an end cap that can rotate around power shaft, and end cap and cavity inner wall are by being threaded.Thereby make main magnet and from magnet shielding in a seal cavity, reach the purpose of magnetic field shielding.
Be connected by bearing between described power shaft and the holder, promptly bearing is fixedlyed connected with power shaft, and bearing is fixedly installed on the holder by bearing pedestal.Like this, power shaft just is connected with holder rotationally, has further guaranteed the coaxial position of power shaft and output shaft.
Regulate by the screw thread of regulating between overcoat and the holder, make and regulate overcoat with respect to holder precession or back-out, thereby the distance of regulating between the outer main magnet on magnet and the power shaft that puts is changed, when main magnet and the distance between magnet are near more, main magnet and big more from the magnetic force moment of torsion between the magnet, main magnet and just big more from the actuating force transmitted between the magnet; On the contrary, when main magnet and the distance between magnet are far away more, main magnet and more little, main magnet and just more little from the actuating force transmitted between the magnet from the magnetic force moment of torsion between the magnet.Like this, by regulating the threaded adjusting between overcoat and the holder, thereby regulate main magnet with from the distance between the magnet, make main magnet and change, to adapt to the demand of different loads transmission from the magnetic force moment of torsion of magnet.
Adopt after this structure, owing to be provided with a governor motion between power shaft and the output shaft, and governor motion is regulated by screw thread, so its adjusting is very convenient; By the adjusting of governor motion, make the magnetic torque control device have the ability of different driving loads, to adapt to the demand of different loads transmission.Therefore, this magnetic torque control device is specially adapted to AutoCappingmachine, with main magnet and from the distance between the magnet, makes main magnet and just can be with bottle cap screwing from the magnetic force transmission between the magnet by governor motion.In the process of bottle cap screwing, when bottle cap was subjected to resistance less than the driving force of magnetic force, bottle cap constantly screwed; When bottle cap was subjected to resistance greater than the driving force of magnetic force, prime mover just can overcome the driving force of magnetic force and produce idle running, and at this moment, bottle cap is tightened on the bottle neck rightly.Therefore, use the AutoCappingmachine of this magnetic torque control device, the phenomenon that can not produce the tight and leakage of spiral cover or lid is come off easily can not produce because of the spiral cover tension makes bottleneck yet and revolve phenomenon disconnected or that bottle cap is broken.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
