Abstract
A kind of gear ring stopping means, it is spacing for the rotatable gear ring being arranged on casing is carried out rotational angle, at least two stopper slot it is provided with outside described gear ring, it connection conduit including being welded on described casing, being connected, with described, the alignment pin that conduit is threaded connection, described stopper slot is stretched in described alignment pin end.A kind of gear ring stopping means provided by the utility model, can be limited to the rotational angle of gear ring in certain scope more accurately.
Description
Technical field
This utility model relates to ground gas turbine field, particularly to a kind of pinion rotation angle to ground gas turbine
The gear ring stopping means that degree is defined.
Background technology
The rotation of gear is 360 °, therefore the gear ring on ground gas turbine or maintain static, or with regard to energy
360 ° of rotations, it is difficult to the rotational angle of gear ring is limited in certain scope.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of gear ring stopping means, to be carried before being reduced or avoided
The problem arrived.
For solving above-mentioned technical problem, the utility model proposes a kind of gear ring stopping means, it is for being arranged on machine
It is spacing that rotatable gear ring on casket carries out rotational angle, is provided with at least two stopper slot outside described gear ring, and it includes weldering
Being connected on the connection conduit of described casing, be connected, with described, the alignment pin that conduit is threaded connection, described alignment pin end is stretched into
Described stopper slot.
Preferably, described connection conduit is provided with an end cap.
Preferably, described alignment pin includes having threaded pin rod and plunger, and described plunger is provided with one group and passes through spring
The ball connected, described connection conduit is evenly equipped with the hemispherical groove that multiple and described ball is corresponding.
Preferably, described plunger and described pin rod are provided with a locking groove at sidewall.
Preferably, described connection conduit is evenly equipped with eight described hemispherical groove.
A kind of gear ring stopping means provided by the utility model, can be limited to one by the rotational angle of gear ring more accurately
In fixed scope.
Accompanying drawing explanation
The following drawings is only intended to, in schematically illustrating this utility model and explaining, not limit model of the present utility model
Enclose.Wherein,
Fig. 1 is that the broken section structure of a kind of gear ring stopping means according to a specific embodiment of the present utility model is shown
It is intended to；
Fig. 2 is the partial cross structural representation of the alignment pin of Fig. 1；
Fig. 3 is the sectional structure schematic diagram connecting conduit of Fig. 1.
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing explanation
Detailed description of the invention of the present utility model.Wherein, identical parts use identical label.
Fig. 1 is that the broken section structure of a kind of gear ring stopping means according to a specific embodiment of the present utility model is shown
It is intended to；Shown in Figure 1, this utility model provides a kind of gear ring stopping means, and it is for being arranged on revolving on casing 1
It is spacing that the gear ring 2 turned carries out rotational angle, is provided with at least two stopper slot 21 outside described gear ring 2, and it includes being welded on institute
Stating the connection conduit 3 of casing 1, be connected, with described, the alignment pin 4 that conduit 3 is threaded connection, institute is stretched in described alignment pin 4 end
State stopper slot 21.
When in described gear ring 2 rotary course, when described stopper slot 21 edge and described alignment pin 4 ends contact, described tooth
Circle 2 can stop the rotation, and therefore, by controlling the arc length of described stopper slot 21, can control the rotatable angle of described gear ring 2
Degree.
In a preferred embodiment, described connection conduit 3 can arrange an end cap 5 further, so can avoid described
When gear ring 2 spinning force is excessive, described alignment pin 4 is ejected.
Fig. 2 is the partial cross structural representation of the alignment pin of Fig. 1, and Fig. 3 is the sectional structure signal connecting conduit of Fig. 1
Figure, sees shown in Fig. 2-3, and in a preferred embodiment, described alignment pin 4 includes having threaded pin rod 41 and plunger 42,
Described plunger 42 is provided with one group of ball 421 connected by spring, and described connection conduit 3 is evenly equipped with multiple and described ball
The hemispherical groove 31 of 421 correspondences, so, when rotating described alignment pin 4, described ball 421 and described hemispherical groove 31
Will send sound during occlusion, operator just can judge the anglec of rotation of described alignment pin 4 the most accurately, thus controls described
Pin rod 41 stretches into the distance of described stopper slot 21.
In a preferred embodiment, described plunger 42 and described pin rod 41 also can be provided with a locking groove at sidewall
411.So, after described alignment pin 4 is screwed into place, a latch can be inserted at described locking groove 411 and (figure not show
Go out), thus avoid the most described alignment pin 4 to rotate displacement.
In a preferred embodiment, described connection conduit 3 is evenly equipped with eight described hemispherical groove 31.
A kind of gear ring stopping means provided by the utility model, can be limited to one by the rotational angle of gear ring more accurately
In fixed scope.
Although it will be appreciated by those skilled in the art that this utility model is to be described according to the mode of multiple embodiments
, but the most each embodiment only comprises an independent technical scheme.In description, so narration is only used to clear
For the sake of, description should be understood by those skilled in the art as an entirety, and by skill involved in each embodiment
Art scheme is regarded as and can be understood protection domain of the present utility model in the way of being mutually combined into different embodiment.
The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to model of the present utility model
Enclose.Any those skilled in the art, the equivalent variations made on the premise of without departing from design of the present utility model and principle,
Amendment and combination, all should belong to the scope of this utility model protection.
