The controllable synchronizer is characterized in that the two-way overrunning clutch is a two-way overrunning clutch of chain-ring type. The electric motor of the electric drive mechanism is a step motor. Compared with the prior art, the controllable synchronizer has the advantages that the controllable synchronizer can avoid the problems of clutch sliding and empty running. The controllable synchronizer can enhance the operating reliability, prolong the serving life of the synchronizer and connect to a computer. The accurate control of the movement amount of the T-type joint can be achieved. The control precision of the synchronizer can be enhanced.
Description
The novel may command steam turbine generator that belongs to of this reality starts the device of speed change and change of load.
Synchronizer is that the control steam turbine generator starts, speed change and the device that adds load shedding.When steam turbine set starts, has the extension lock, functions such as control turbine speed.During unit operation, handle the rotating speed load that synchronizer can change unit, it is a vitals of Turbo-generator Set regulating system.Existing synchronizer mainly is by T junction, transmission shaft, and direct current generator and driving mechanism thereof, free wheel device and driving gear are formed.T shape connecting head links to each other with the T-slot of the control box throttle of governor box throttle.Drive the case throttle with this and move, the control box accelerator open degree.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 T shape connecting head by actuation gear driving mechanism and free wheel device and moves back and forth.During manually-operable, because the self-locking of direct current generator driving mechanism, direct current generator can not rotate on the spot, and at this moment the handwheel of hand-operating device rotates directly by free wheel device, drives the gear rotation coaxial with leading screw, thereby makes transmission shaft reciprocating.This synchronizer has the following disadvantages:
(1) free wheel device wherein is a roller type, and wearing and tearing easily in use easily produce and skid and the null phenomenon, cause master side far away electric functions to break down.
(2) because direct current generator is uncontrollable, make synchronizer wayward and be not easy to communication, be unfavorable for the automation of unit.
The purpose of this utility model just is to provide a kind of controlled synchronizer that can avoid above-mentioned 2 deficiencies.
The purpose of this utility model is achieved in that it comprises T junction, directly is connected in the transmission shaft under this T junction, double rolling key clutch, manual transmission and by motor-driven electric transmissio mechanism; Said manual transmission and said electric transmissio mechanism are transmitted in said transmission shaft between said double rolling key clutch respectively by oneself, it is characterized in that: said double rolling key clutch is the chain ring type double rolling key clutch, and the motor of said electric transmissio mechanism is a stepper motor.
Working principle of the present utility model is: utilize said electric transmissio mechanism can carry out distant place control.Promptly turn round, and this electric transmissio mechanism drives said transmission shaft rotation between said chain ring type double rolling key clutch, make said T junction produce to-and-fro motion by the said electric transmissio mechanism of said step motor drive.Because said manual transmission and said electric transmissio mechanism are transmitted in said transmission shaft between said double rolling key clutch respectively by oneself, so when said electric transmissio mechanism turned round, said manual transmission was unaffected, not by interlock.When desiring directly then to drive said manual transmission when manually driving said T junction, this mechanism drives said transmission shaft rotation between said chain ring type twin-direction clutch.In like manner, when said manual transmission turned round, said electric transmissio mechanism was unaffected, not by interlock.
Compared with the prior art the utility model has the following advantages:
(1) owing to adopt the chain ring type double rolling key clutch, thoroughly avoids the sliding and idle stroke problem of clutch button, improved reliability, prolonged the working life of synchronizer.
(2) owing to adopt stepper motor, can be connected, can accurately control the amount of movement of T junction, improve the control accuracy of synchronizer with computer.This directly helps the automatic improving of steam turbine set.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure schematic representation of the present utility model.
According to Fig. 1, synchronizer of the present utility model comprises T junction 5, directly be connected in the transmission shaft 4 under the T junction 5, chain ring type double rolling key clutch 6, the affixed gear 1 on the main shaft of stepper motor 7 that constitutes electric transmissio mechanism that constitutes the rotation hand wheel 3 on the inner core that is enclosed within double rolling key clutch 6 of manual transmission and drive by stepper motor 7; Gear 1 is meshed with the actuation gear 2 of chain ring type double rolling key clutch 6.The external screw-thread of transmission shaft 4 is connected with the thread bush 9 that got up by bearing bracket, and this thread bush 9 has gear disk 10, and this gear disk 10 is meshed with the output gear 8 of double rolling key clutch 6.
There is not the problem of skidding with idle stroke in chain ring type double rolling key clutch 6, is a kind of desirable free wheel device, and its structure has belonged to known technology, and (as application number is 98117227.X.Name is called the chain ring type list, the structure of double rolling key clutch or the ROC-SL75 type double rolling key clutch that has been produced), so it no longer is described in detail in detail here.When stepper motor 7 runnings, gear 1 rotates, and actuation gear 2 is rotated, and the output gear 8 of twin-direction clutch 6 also rotates synchronously.So gear disk 10 is turned, thread bush 9 rotates, and makes transmission shaft 4 rotations produce the moving forward or backward of T junctions 5.
When the actuation gear 2 of double rolling key clutch 6 rotated, the inner core of twin-direction clutch 6 did not rotate, so handwheel 3 does not rotate.That is to say that manual transmission is unaffected, not by interlock when working as the electric transmissio mechanism running.
When desiring directly when manually driving said T junction, then rotation hand wheel 3, so the inner core of twin-direction clutch 6 rotates, output gear 8 rotated.At this moment, actuation gear 2 does not rotate, and electric transmissio mechanism is unaffected, not by interlock.
As seen by above-mentioned, the electronic and manual nothing mutually influence of synchronizer can freely be changed.
Further, stepper motor 7 can be connected with computer, by by the rotating speed of computer-controlled stepper motor 7 and corner etc., can accurately control the amount of movement of T junction 5, improves the control accuracy of synchronizer.So can satisfy Turbo-generator Set requirement to synchronizer under different operating modes, this directly helps the automatic improving of steam turbine set.
