This Straight pull single crystal growing furnace has following characteristics with seed crystal lifting gear and prior art:
1. push up the chamber.Top top of chamber centre hole is processed upper and lower step surface, mounting plane bearing in the step with one heart.Two surface bearings rely on upper and lower step transition to cooperate, guarantees concentric with top top of chamber centre hole, again by pin connection pulley assembly.During working order, it is in a single day stressed to penetrate the pulley rope, and pulley assembly drives bearing pin and rotates to required angle automatically.Be that the rope center overlaps with the brilliant magnetic fluid rotating shaft center of changeing.Even the chamber, top is promoting the variation of chamber generation setting angle at every turn, the inner pulley assembly all can rotate by slight stressed down at rope (50 gram) drive bearing pin automatically, and it is concentric to make rope and crystalline substance change the magnetic fluid rotating shaft.The wheel rope is subjected to pulling force big more, and its pulley assembly angle of rotation is accurate more, and rope is accurate more with the brilliant magnetic fluid rotating shaft concentricity of changeing.Rope is stressed greater than 5Kg during working order.Pulley assembly upper sensor flexible lead passes chamber, top through wires hole, fixedlys connected with the top cover flange; The trace rotation in 10 ° of scopes of the actual required angle of rotation maximum of pulley assembly.Even pull down rope, because the lead constraint, the positive and negative rotating range of pulley assembly also is no more than 90 °.
But 2. pull transmission shaft.But bipolar variator transmission output shaft is the pull transmission shaft, but bipolar variator is given the pull transmission shaft by the flat key driving torque, but the pull transmission shaft passes through the inner hole sleeve of band keyway again outside the splined shaft axle, and transmission shaft endoporus flat key driving torque is given and promoted the chamber female splined shaft, finishes the moment of torsion transmission.But pull transmission shaft advantage: positive and negative stable drive, the required torque size can be controlled, the speed of rotation may command, apply moment of torsion according to socket screw hexagon wrench in the rotary course, can judge flexibly whether stuck point is arranged in the rotary course, counter-rotating in time avoids the device security accident to take place; Whole maintenance process, flexibly, quick, save time, single can finishing the work.But pore area inner hole key slot in pull transmission shaft one end, effect: location and driving torque are given and are promoted the chamber splined shaft; Another axle head has hex tool hole in six millimeters, effect: manual rotating drive shaft; The hex tool hole is processed with the M5 screw thread with one heart in six millimeters, effect: by being screwed into the screw rod in the threaded hole, but the pull transmission shaft that takes out, packs into; But pull transmission shaft external diameter processing keyway.Effect: but bipolar transmission torque is passed to the pull transmission shaft.
3. rotary components.Crystalline substance in the rotary components rises base plate and is processed with through wires hole, and slip ring power supply signal bus vertically by brilliant belt wheel and the base plate through wires hole of changeing, is connected with the electrical part of the required power supply of the brilliant lifting mechanism of son.Advantage: cabling mode is reasonable, structure is ingenious, good looking appearance (circuit is all walked internally, and good looking appearance almost be can't see cabling).
4. the brilliant type of drive of changeing.The brilliant commentaries on classics installed brilliant speed reduction unit and the brilliant drive-motor that changes of changeing of worm and gear on the support, changeing the static mount pad of magnetic fluid with crystalline substance fixes, the brilliant drive-motor that changes drives the brilliant speed reduction unit that changes, after the brilliant commentaries on classics of the worm and gear speed reduction unit speed change, small pulley that output shaft is installed drives many contracts band, the brilliant big belt wheel that changes is given in the transmission of many contracts band, the big belt wheel of brilliant commentaries on classics is fixed on brilliant the commentaries on classics on the rotatable shaft shoulder of magnetic fluid, and brilliant the commentaries on classics on the big belt wheel is equipped with young brilliant lifting mechanism, rotates thereby drive young brilliant lifting mechanism.
5. slip ring circuit.Slip ring is divided into ring in static outer shroud and the rotation, and inner and outer rings is connected with many group leads, and lead connects the power-on and power-off device respectively, and inside and outside slip ring electrically conducting manner is fixedly carbon brush and conductive copper.Working order: outer slip ring and outer slip ring are organized the lead stationary fixing more, and interior slip ring and interior slip ring are organized the rotation of lead circumference more.
6. brilliant ascending, descending transmission.At a slow speed during lifting, slow speed motor is by first shaft coupling, first shaft coupling drives clutch pack, clutch pack is imported bipolar variator, but bipolar variator is by the pull transmission shaft, but the pull transmission shaft drives splined shaft, and splined shaft drives the rotation of clue pipe, after the rope that twines on the clue pipe was walked around pulley assembly, up-and-down movement was at a slow speed done with the brilliant also vertical and brilliant magnetic fluid baseplane of changeing of magnetic fluid endoporus centres of changeing in the rope center.During fast lifting, fast speed motor is by second shaft coupling, second shaft coupling is imported bipolar variator, but bipolar variator is by the pull transmission shaft, but the pull transmission shaft drives splined shaft, splined shaft drives the rotation of clue pipe, and after the rope that twines on the clue pipe was walked around pulley assembly, up-and-down movement was at a slow speed done with the brilliant also vertical and brilliant magnetic fluid baseplane of changeing of magnetic fluid endoporus centres of changeing in the rope center.
7. the spacing control of brilliant ascending, descending.Splined shaft rotates, synchronous pulley is installed on the splined shaft is done synchronous rotation, synchronous pulley is given and to be lifted a position-limit mechanism by the transmission that will rotatablely move of synchronous band, will rotatablely move and change translational motion into by lifting a position-limit mechanism, lifts a position-limit mechanism control rope and is in correct position.
