Specific embodiment
For the technical scheme being illustrated more clearly that in various embodiments of the present invention, below will be to required in embodiment description
The accompanying drawing using is briefly described.
Embodiment 1
Refer to shown in Fig. 1 and Fig. 2, it is respectively a kind of present invention Turbine Barring Gears ratchet motor machine jiggering and implements
The front view of example one and side elevational cross-section schematic diagram, described ratchet motor machine jiggering includes: motor 1, decelerator 2, disk move
Gear train is comprising: the first disk moving gear 31, the second disk moving gear 4, the 3rd disk moving gear 5 (afterbody jiggering gear), disk
Car ratchet 6, gear shaft 7, clutch handle 9, wherein said motor 1 is connected with described decelerator 2, described first disk moving gear
31 be located at described decelerator 2 in, described first disk moving gear 31, described second disk moving gear 4, described 3rd disk moving gear 5 according to
Secondary engagement, described jiggering ratchet 6 is engaged in clutch handle 9 bottom with steam turbine ratchet stop 13, and described jiggering ratchet 6
Coaxial with described 3rd disk moving gear 5, clutch shaft 8 is fixed on box house, and clutch shaft 8 is welded with shift fork 10, pulls limit
Position device 13 is moved clutch handle 9 shift fork 10 on clutch shaft 8 can be made to stir jiggering ratchet 6 and slides on gear shaft 7；In conjunction with
Shown in Fig. 8, described jiggering ratchet 6 end face has one group of scallop hole 12 of circumferential ring type arrangement, and described 3rd disk moving gear 5 one side has
One group of sawtooth pattern gear block 11 is corresponding with described scallop hole 12, and described sawtooth pattern gear block 11 can wedge described disk all the time
In scallop hole 12 on car ratchet 6 end face, described jiggering ratchet 6 can slide on gear shaft 7 simultaneously.
Before jiggering starts, described jiggering ratchet 6 and the 3rd disk moving gear 5 are in semi-engagement state, such as Figure 11 Figure 12 Figure 13
Shown in Figure 14.
Using described clutch handle 9, described jiggering ratchet 6 is adjacent to described 3rd disk moving gear 5, described sawtooth pattern
Gear block 11 is completely embedded in described scallop hole 12 it is ensured that described jiggering ratchet 6 can be turned jointly with described 3rd disk moving gear 5
Dynamic, as shown in Fig. 7 Fig. 8 Fig. 9 Figure 10.
When starting jiggering, described motor 1 energising makes described decelerator 2 work, and the first disk on described decelerator 2 moves
Gear 31 and described second disk moving gear 4 engagement rotation, are then driven and are rotated with described 3rd disk moving gear 5, because of the described 3rd
Disk moving gear 5 is engaged by described sawtooth pattern gear block 11 and scallop hole 12 with described jiggering ratchet 6, makes described 3rd disk move tooth
Wheel 5 described jiggering ratchet 6 common rotation of drive.
As shown in Fig. 7 Fig. 8 Fig. 9 and Figure 10, when the speed of the 3rd disk moving gear 5 is more than or close to described jiggering ratchet 6
During speed, the vertical plane of described sawtooth pattern gear block 11 is faced directly with the one of described scallop hole 12 and is suited, and jiggering ratchet 6 is by the 3rd disk
Described sawtooth pattern gear block 11 on moving gear 5 promotes, and makes described 3rd disk moving gear 5 become active rotation, described jiggering spine
Wheel 6 becomes passive rotation, thus described jiggering ratchet 6 drives steam turbine pawl wheel.And steam turbine ratchet running speed is more than
During jiggering ratchet 6, due to the curved surface marriage relation of mating surface, the back side of anti-push-plate car ratchet 6 ratchet is made by steam turbine ratchet
Reversion, make described scallop hole 12 suit the vertical plane that sawtooth pattern gear block 11 is left in face immediately, and make the engagement of described sawtooth pattern
Inclined-plane touching the another of described scallop hole 12 of block 11 suits face, and described scallop hole 12 cannot be with described sawtooth pattern gear block 11
Inclined-plane suits and leads to described jiggering ratchet 6 to completely disengage from and the engaging of steam turbine ratchet, and is in described 3rd disk moving gear 5
Half disengaged position, as shown in Figure 11, Figure 12, Figure 13, Figure 14.Jiggering ratchet 6 is constitutionally stable important with the 3rd disk moving gear 5
Part, and play a protective role be respectively be located at jiggering ratchet 6 and the 3rd disk moving gear 5 on scallop hole 12 and sawtooth pattern nibble
Close block 11, even if there being even several sawtooth pattern gear blocks 11 to damage, other sawtooth pattern gear blocks 11 still can complete work
Make, rather than defencive function is ridden on a widget.It is pointed out that described scallop hole 12 and the engagement of described zigzag
The position of block 11 is interchangeable, will scallop hole 12 be fixedly installed on the 3rd disk moving gear 5, and zigzag gear block 11 fixation is set
Put on jiggering ratchet 6, the function that it plays is consistent with before transposition with effect.Jiggering ratchet 6 and the 3rd disk moving gear 5
Disengage function, play the effect of the overall barring gear of protection and steam turbine ratchet.Clutch handle 9 was in locking before moving
State, because with the stop 13 that its underpart is engaged have a projection 14 can with jiggering casing on the corresponding insertion of lock hole, when extracting
After stop 13, described raised 14 make clutch handle 9 be in can to move state from locking in the hole pull-out, in described stop 13
Also a spring can be contained, make raised 14 can voluntarily embed when running into lock hole.This stop 13 can effectively prevent clutch
Handle 9 is surprisingly moved, and Accident prevention occurs.Jiggering ratchet 6 and the 3rd disk only need to be moved tooth by clutch handle 9 by this jiggering
Wheel 5 is adjacent to the part that can complete whole manual operations, and follow-up work is voluntarily completed by barring gear, without people when occurring unexpected
Industry control jiggering ratchet 6 is separated with steam turbine ratchet, and therefore this barring gear is simple to operate, safe and efficient.
Embodiment 2
Refer to shown in Fig. 3 and Fig. 4, it is the present invention a kind of Turbine Barring Gears ratchet motor machine jiggering embodiment two
Front view and side elevational cross-section schematic diagram, its difference with embodiment one be herein disk moving gear group to increased a disk dynamic again
Gear 32, thus extending gear transmission chain, increases moment of torsion, but the operation logic of whole motor machine jiggering is identical.
Embodiment 3
Refer to shown in Fig. 5 and Fig. 6, it is respectively a kind of present invention Turbine Barring Gears ratchet motor machine jiggering and implements
The front view of example three and side elevational cross-section schematic diagram, with the difference of embodiment two, it is that disk moving gear group herein increases further
One disk moving gear 33, thus extending gear transmission chain further, increases moment of torsion, but the fortune of whole motor machine jiggering
Row principle is identical, also illustrate that in the present invention, the disk moving gear group for intermediate transmission is can be according to actual needs simultaneously
Carry out the setting of multiple disk moving gears.
