Embodiment
In order to be illustrated more clearly in the technological scheme in each embodiment of the utility model, below the accompanying drawing used required in describing embodiment is briefly described.
Embodiment 1
Refer to shown in Fig. 1 and Fig. 2, it is respectively plan view and the side elevational cross-section schematic diagram of a kind of Turbine Barring Gears ratchet of the utility model motor machine jiggering embodiment one, described ratchet motor machine jiggering comprises: motor 1, retarder 2, it comprises to coil moving gear group: the first dish moving gear 31, second dish moving gear 4, 3rd dish moving gear 5 (afterbody jiggering gear), jiggering ratchet 6, gear shaft 7, clutch handle 9, wherein said motor 1 is connected with described retarder 2, described first dish moving gear 31 is positioned at described retarder 2, described first dish moving gear 31, described second dish moving gear 4, described 3rd dish moving gear 5 engages successively, described jiggering ratchet 6 engages in clutch handle 9 bottom with steam turbine ratchet snubber 13, and described jiggering ratchet 6 and the described 3rd to coil moving gear 5 coaxial, clutch shaft 8 is fixed on box house, clutch shaft 8 is welded with shift fork 10, pull snubber 13 to move clutch handle 9 shift fork 10 on clutch shaft 8 can be made to stir jiggering ratchet 6 slide on gear shaft 7, shown in composition graphs 8, one group of fan shaped borehole 12 that described jiggering ratchet 6 end face has circumferential ring type to arrange, described 3rd dish moving gear 5 one side has one group of zigzag fashion gear block 11 corresponding with described fan shaped borehole 12, described zigzag fashion gear block 11 can be wedged in the fan shaped borehole 12 on described jiggering ratchet 6 end face all the time, and described jiggering ratchet 6 can slide on gear shaft 7 simultaneously.
Before jiggering starts, described jiggering ratchet 6 and the 3rd coils moving gear 5 and is in half engagement, as shown in Figure 11 Figure 12 Figure 13 Figure 14.
Utilize described clutch handle 9 that described jiggering ratchet 6 and the described 3rd is coiled moving gear 5 to be adjacent to, described zigzag fashion gear block 11 embeds in described fan shaped borehole 12 completely, ensure that described jiggering ratchet 6 can coil moving gear 5 common rotation with the described 3rd, as shown in Fig. 7 Fig. 8 Fig. 9 Figure 10.
When starting jiggering, described motor 1 energising makes described retarder 2 work, the first dish moving gear 31 on described retarder 2 coils moving gear 4 engagement rotation with described second, then drive and coil moving gear 5 rotate with the described 3rd, because described 3rd dish moving gear 5 is engaged by described zigzag fashion gear block 11 and fan shaped borehole 12 with described jiggering ratchet 6, described 3rd dish moving gear 5 is made to drive described jiggering ratchet 6 common rotation.
As shown in Fig. 7 Fig. 8 Fig. 9 and Figure 10, when the speed of the 3rd dish moving gear 5 be greater than or speed close to described jiggering ratchet 6 time, the vertical plane of described zigzag fashion gear block 11 and one of described fan shaped borehole 12 is faced directly and is suited, jiggering ratchet 6 is promoted by the described zigzag fashion gear block 11 on the 3rd dish moving gear 5, described 3rd dish moving gear 5 is made to become active rotation, described jiggering ratchet 6 becomes passive rotation, thus described jiggering ratchet 6 drives steam turbine pawl wheel.And steam turbine ratchet running speed is when being greater than jiggering ratchet 6, due to the curved surface marriage relation of combination surface, the back side of anti-push-plate car ratchet 6 ratchet is made it reversion by steam turbine ratchet, described fan shaped borehole 12 is made to suit the vertical plane that zigzag fashion gear block 11 is left in face immediately, and another making the inclined-plane of described zigzag fashion gear block 11 touch described fan shaped borehole 12 suits face, described fan shaped borehole 12 cannot suit with the inclined-plane of described zigzag fashion gear block 11 and cause described jiggering ratchet 6 to depart from completely and the engaging of steam turbine ratchet, coil moving gear 5 be in half disengaged position with the described 3rd, as Figure 11, Figure 12, Figure 13, shown in Figure 14.It is constitutionally stable vitals that jiggering ratchet 6 and the 3rd coils moving gear 5; and play a protective role be lay respectively at jiggering ratchet 6 and the 3rd dish moving gear 5 on fan shaped borehole 12 and zigzag fashion gear block 11; even if having one even several zigzag fashion gear blocks 11 damage; other zigzag fashion gear blocks 11 still can be finished the work, but not are ridden in by protective function on a widget.It is to be noted, the position of described fan shaped borehole 12 and described zigzag fashion gear block 11 is interchangeable, be fixedly installed on the 3rd dish moving gear 5 by fan shaped borehole 12, be fixedly installed on by zigzag fashion gear block 11 on jiggering ratchet 6, its function played is consistent with before transposition with effect.Jiggering ratchet 6 and the 3rd coils the disengagement function of moving gear 5, plays the effect of the overall barring gear of protection and steam turbine ratchet.Clutch handle 9 was in the lock state before moving, because having a projection 14 correspondingly with the locking aperture on jiggering casing to insert with the snubber 13 that its underpart is engaged, when after extracting snubber 13 described protruding 14 in locking aperture pull-out clutch handle 9 is in can move state, also can containing a spring in described snubber 13, making protruding 14 can embed voluntarily when running into locking aperture.This snubber 13 can effectively prevent clutch handle 9 from surprisingly being moved, and Accident prevention occurs.Jiggering ratchet 6 and the 3rd only need be coiled moving gear 5 by clutch handle 9 and be adjacent to the part that can complete whole manual operation by this jiggering, follow-up work is completed voluntarily by barring gear, be separated with steam turbine ratchet without the need to manual control jiggering ratchet 6 when meeting accident, therefore this barring gear is simple to operate, safe and efficient.
Embodiment 2
Refer to shown in Fig. 3 and Fig. 4, it is plan view and the side elevational cross-section schematic diagram of a kind of Turbine Barring Gears ratchet of the utility model motor machine jiggering embodiment two, the difference of itself and embodiment one is to coil moving gear group herein and turn increases one and coil moving gear 32 thus extend gear transmission chain, increase moment of torsion, but the running principle of whole motor machine jiggering is identical.
Embodiment 3
Refer to shown in Fig. 5 and Fig. 6, it is respectively plan view and the side elevational cross-section schematic diagram of a kind of Turbine Barring Gears ratchet of the utility model motor machine jiggering embodiment three, the dish moving gear group that the difference of itself and embodiment two is herein further increases one and coils moving gear 33 thus extend gear transmission chain further, increase moment of torsion, but the running principle of whole motor machine jiggering is identical, to also illustrate that in the utility model for the dish moving gear group of intermediate transmission it is to carry out the setting of multiple dish moving gear according to actual needs simultaneously.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for the utility model, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that the utility model claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
