Abstract
The utility model provides a controllable intelligent synchronizer. A rigidity drive mechanism is used to replace an overrunning clutch. A step motor is used to replace a direct current electric motor. A bearing of a drive shaft adopts an axial thrust bearing. The utility model has the advantages that the problems of slippage and idle stroke caused by a clutch are eliminated because of the elimination of the overrunning clutch; because the step motor is adopted, the utility model can communicate with the computer and set various speed outputs, which is favorable for the automatic reconstruction of steam turbine units. The axial thrust bearing is adopted and the drive mechanism is improved, which makes the pretightening force of the bearing and the axial clearance adjustable. The controllable intelligent synchronizer is used in the steam turbine generating units.
Description
The utility model belongs to the device of startup of control steam turbine generator and change of load.
Synchronizer is the startup of control steam turbine generator, speed change and the device that adds load shedding.When steam turbine starts, has the extension lock, functions such as control turbine speed.During unit operation, handle rotating speed, load that synchronizer can change unit, it is a vitals of Turbo-generator Set regulating system.Existing synchronizer mainly is made up of T type connecting head, transmission shaft, direct current generator and driving mechanism, free wheel device and driving gear.T type connecting head links to each other with the control guiding valve T type groove of speed regulator pilot valve, drives guiding valve with this and moves, the aperture of control pilot valve.This synchronizer can distant place electric operating, manually-operable on the spot again.Remote operation is realized by direct current generator.Direct current generator finally makes transmission shaft drive the to-and-fro motion of T type connecting head by actuation gear driving mechanism and free wheel device.On the spot during manually-operable, because the self-locking of direct current generator driving mechanism, direct current generator can't passive rotation, and at this moment the handwheel of hand-operating device rotates and directly passes through free wheel device, drive the gear rotation coaxial, thereby make transmission shaft (leading screw) reciprocating with leading screw.This synchronizer has the following disadvantages:
(1) free wheel device wherein is roller type or chain ring type, and wearing and tearing easily in use easily produce and skid and the idle stroke phenomenon, cause distant place electric functions to break down.
(2) because direct current generator is uncontrollable, has only an output speed.Control accuracy is low, makes synchronizer wayward and be not easy to communication, is unfavorable for the automation of unit.
(3) spring bearing of transmission shaft is common ball bearing, fixes by jackscrew between gear and the screw.Be easy to generate axial clearance, gear and screw are easy to generate and come off.
The purpose of this utility model just is to provide a kind of Controllable Intelligence Synchronizer that can avoid above-mentioned 3 deficiencies.
The purpose of this utility model is achieved in that it is to having the following improvement of synchronizer now: replace free wheel device with positive drive mechanism, realize that by motor manual and electric does not disturb mutually.Replace direct current generator with stepper motor, export multiple rotating speed by the software set motor as required.Because the transmission shaft thrust output reaches 1000kg sometimes, the spring bearing axial thrust bearing of transmission shaft improves drive mechanism, and its axial clearance can be adjusted, and improves transmission accuracy.The technical solution of the utility model is: it comprises T type connecting head, transmission shaft, handwheel and driving mechanism, the axial thrust bearing that it is characterized in that: further comprising stepper motor, positive drive mechanism and supporting drive shaft, positive drive mechanism wherein is made up of axle and the gear that is fixed on these two ends, these two gears separately with the actuation gear of stepper motor, the gear engagement on the transmission shaft.
Working principle of the present utility model is:
(1) electronic remote operation.Because motor has multiple output speed, in the control room operation, can accurately control the steam turbine raising speed, add load shedding, hang lock fast.Motor driven gear rotates manual axle, rotates by the gear driven screw, and transmission shaft is moved forward and backward.
(2) manually-operable.Hand on the spot handwheel, driven gear and screw rotate, and transmission shaft is moved forward and backward.Drive simultaneously motor yet and rotate, and motor is not subjected to manual interference.
The utility model with there to be technology to compare, have the following advantages:
(1) owing to cancel free wheel device, thoroughly eliminated owing to skidding and the idle stroke problem that clutch causes.Improved reliability.
(2) owing to adopt stepper motor, can with the computer communication, multiple speed output can be set.Can accurately control the amount of movement of T connector, can realize remote operation steam turbine raising speed, improve the control accuracy of synchronizer, help the automatic improving of steam turbine set.
(3) adopt axial thrust bearing, improved drive mechanism, bearing pre-fastening and axial clearance can be adjusted.Improve the transmission accuracy of synchronizer, eliminated gear and screw and produced the hidden danger that comes off, reduced the maintenance of carrying out greatly owing to drive gap and adjusted number of times, prolonged the working life of synchronizer.
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a kind of concrete structure schematic representation of the present utility model.
It comprises T type connecting head 9, handwheel 4 and driving mechanism (gear 10, transmission shaft 5 and screw 7), it also comprises the axial thrust bearing 8 of stepper motor 1, positive drive mechanism and supporting drive shaft, positive drive mechanism wherein is made up of axle 12 and the gear 3,11 that is fixed on these two ends, gear 3 meshes with the actuation gear 2 of stepper motor, gear 10 engagements on gear 11 and the transmission shaft.Stepper motor 1 actuation gear 2 rotates positive drive organization gear 3, axle 12, gear 11 and handwheel 4, and gear 11 driven gears 10 rotate screw 7, and transmission shaft 5 is moved forward and backward, and T connector 9 is fixed on the transmission shaft.Round nut 6 is to adjust bearing 8 pretightening forces.Same driven gear 2 and motor 1 rotated when handwheel rotated, and the rotation of following of motor does not influence performance electrically and manually.
