The rotor3 is arranged at centre of the motor shell1. Rotating spindles of the rotor3 are arranged at two end of the motor shell1. The rotor3 is in a shape of a cylinder body, at one end of which is provided with a fixed stator2 and at the other end of which is provided with a winding component4 which can turn around the rotor3 in radian rotation. The moveable and speed adjusting motor not only has a simple structure, a reliable performance, a convenient maintenance, but also has a wide smooth speed adjusting range, an extensive application range which can be extensively used in facilities of explosive and inflammable areas.
Description
The utility model relates to a kind of improvement of buncher, specifically a kind of moving type buncher.
At present, the motor that uses divides direct current machine and alternating current machine, alternating current machine because of make easily, the reliability height of motor own, contactless element, cost be low, so be widely used, but motor stepless speed control problem is a difficult problem under the mechanical load of speed governing in broad range, though it is DC motor has obtained good solution on the speed governing problem, low because of direct current machine manufacturing technology complexity, the reliability of motor own, contact element, cost height are arranged, so on using, also be very limited.In the prior art, the stepless speed-regulating motor that moves axially stator or rotor is arranged, as high-performance birotor asynchronous machine and cage type stepless speed-regulating motor, the buncher that moves for rotor, though solved the problem of stepless speed regulation in the machine, the movable part volume is big, inertia is big but exist, and is difficult to realize the drawback of the electronic speed governing of complete machine; For the motor that stator moves, it moves the stator regulating branch does not have locking mechanism, and after stator was removed from former magnetic coupling position, because the effect of magnetic pull, stator will produce to original magnetic coupling locality and move, and causes the speed governing shakiness; Also have in addition changing the power supply frequency, change the motor logarithm, to change method such as revolutional slip and realize the motor etc. of speed governing, though these speed regulating methods also can speed governing, equipment investment is big, it is complicated to make, volume is big, is of limited application.
The purpose of this utility model be to provide a kind of not only simple in structure, easy to manufacture, production cost is low, reliable, easy to maintenance, and the stepless speed control scope is big, applied range, adjusting are controlled easily, volume is little, the moving type buncher that speed governing is stable.
The utility model is achieved in that this moving type buncher, adopt moving, fixed in conjunction with the change that realizes the magnetic coupling amount, and then realization speed governing, by motor casing, fixed stator, rotor, support constitutes, motor casing is a cylindrical shell, rotor is located at the center of motor casing, the rotation axis of rotor is located at the two ends of motor casing, rotor is a cylinder, end at rotor is established fixed stator, establishes winding spare at the other end of rotor, and winding spare that can rotate is made radian and rotated, by the rotation of winding spare and the displacement of winding spare relative fixed stator, realize the change of the magnetic coupling amount of fixed stator and winding spare.The middle part spiral-lock semicircle arcuation worm gear of winding spare, and be fixed on the worm gear set bolt on the core body of winding spare, slip cap is established at the two ends of winding spare, and fix with set bolt, semicircle arcuation worm gear and worm engaging, worm screw is rotated, then driving semicircle arcuation worm gear rotates, worm screw stops operating, then the position of semicircle arcuation worm gear is locked, and slip cap is stuck in the motor casing inwall rail groove, makes winding spare make arcuation in rail groove and rotates, on the worm screw housing, worm screw housing and motor casing are fixed as one worm screw by bearing fixing; The rotate displacement radian of sub-relative fixed stator and semicircle arcuation worm gear of winding spare is consistent with the transmission distance of worm screw, and by worm screw the resting position of residing position, locking winding spare when static, so that speed governing is stable, micro servo motor is by speed governing machinery load cell control in the broad range.When using the utility model, the buncher that will be shifted is connected with mechanical load, and mechanical load is connected with transducer, and transducer is connected with micro servo motor, start buncher, when mechanical load requires speed governing, send instruction by transducer, transducer instructs micro servo motor to open again, micro servo motor starts, drive worm screw and rotate, thereby winding spare is rotated, realize speed governing.
The utility model has the advantages that: compare with existing buncher, not only simple in structure, cheap, reliable, easy to maintenance, and the stepless speed control scope is big, applied range, adjusting control easily, speed governing are stablized, volume is little, the startup of large and medium-sized especially motor can not have impact to electrical network, need not add starting device, is particularly useful for inflammable, explosive occasion facility strategic point.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structure office cross-sectional schematic.
Fig. 2 is the utility model cross-sectional schematic vertically.
Fig. 3 is the utility model winding spare running status schematic diagram.
Make the utility model with reference to accompanying drawing 1,2,3.This moving type buncher, constitute by motor casing 1, fixed stator 2, rotor 3, support 13, motor casing 1 is a cylindrical shell, rotor 3 is located at the center of motor casing 1, the rotation axis of rotor 3 is located at the two ends of motor casing 1, and rotor 3 is a cylinder, establishes fixed stator 2 at an end of rotor 3, establish winding spare 4 at the other end of rotor 3, winding spare 4 son 3 that can rotate is made radian and is rotated.The middle part spiral-lock upper semi-circle arcuation worm gear 8 of winding spare 4, and be fixed on worm gear set bolt 9 on the core body of winding spare 4, slip cap 6 is established at the two ends of winding spare 4, and it is fixing with set bolt 7, semicircle arcuation worm gear 8 and worm screw 10 engagements, slip cap 6 is stuck in the motor casing 1 inwall rail groove, and worm screw 10 is fixed on the worm screw housing 12 by bearing 11, and worm screw housing 12 is fixed as one with motor casing 1; The rotate displacement radian of sub 3 relative fixed stators 2 and semicircle arcuation worm gear 8 of winding spare 4 is consistent with the transmission distance of worm screw 10; and by worm screw 10 resting position of residing locking position winding spare 4 when static; the startup of micro servo motor 5 and shutdown are by the mechanical load transducer control of speed governing in the broad range.
