Oil tank, lube pipe, lubricating oil control system, driving mechanism, link mechanism, the linkage ring etc. that traditional regulative mode needs are saved
Structure simplifies structure, reduces cost.
Detailed description of the invention
Fig. 1 is the fast structural schematic diagram of adjusting of the utility model angle-regulating block group；
Fig. 2 is the adjusting block scheme of installation of the utility model angle-regulating block group；
Fig. 3 is that the adjusting of the utility model angle-regulating block group changes schematic diagram fastly.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.
As depicted in figs. 1 and 2, a kind of angle-regulating block group provided by the utility model, for adjusting engine stator leaf
The angle of piece, the angle-regulating block group include multiple adjusting blocks 1, and the adjusting block 1 is rectangular flat plate, the adjusting block 1
A short side on be provided with cotter way 2, shape is adapted with the pin 5 for fixing rocker arm, the adjusting block 1 another
Parallel surface slot compatible with the parallel surface of axle journal 6 on stator blade is provided on short side；In one long side of the adjusting block 1
It is additionally provided with mistake proofing groove 4, top and bottom are anti-loaded when preventing from installing.
Also, the axle center of the cotter way 2 of multiple adjusting blocks 1 of the angle-regulating block group and the upper axle journal slot
3 axle center spacing R is fixed；Wherein
As shown in figure 3,2 axle center of cotter way of each adjusting block 1 is along the adjusting block 1 in multiple adjusting blocks 1
Distance L on short side direction to upper 3 axle center of axle journal slot is different.
When immobilizing in the axle center of the cotter way 2 with the axle center spacing R of the upper axle journal slot 3, when the distance of L is by Fig. 3
In B state under length when becoming the length under A condition, a ° of angle of value changes therewith, and the value of L is with a ° of value at positive
It closes.For example, in engine test, it, can be according to following setting for easy making process when the adjusting block produces and processes:
If R value is set as 28.57mm, L can approximately as shown in table 1 with a ° of relationship:
Table 1
If R value is set as 57.29mm, L can approximately as shown in table 2 with a ° of relationship:
Table 2
In engine performance test part, after determining the angle that stator blade needs to adjust, due on engine crankcase
Equipped with multi-disc stator blade, identical adjusting block in multiple angle-regulating block groups can be chosen, stator blade angle is adjusted
Section.
To use L=0mm, on the basis of the angle of stator blade when a °=0 angle-regulating block, when installation, first will
The upper axle journal slot 3 of angle-regulating block is mounted on stator blade on axle journal, is then rotated stator blade, is made the pin of angle-regulating block
Slot 2 is directed at the position of fixation hole on casing, fixed by pin 5, for example, if stator blade needs to adjust 1 degree, select a °=
1 angle-regulating block after the upper axle journal slot 3 of angle-regulating block is mounted on stator blade on axle journal, then rotates stator leaf
Piece makes the cotter way 2 of angle-regulating block be directed at the position of fixation hole on casing, then the angle of stator blade rotation is 1 degree.
Stator blade angle is adjusted by the angle-regulating block, saves oil tank, cunning that traditional regulative mode needs
The structures such as oil pipe line, lubricating oil control system, driving mechanism, link mechanism, linkage ring, simplify structure, reduce cost.Including multiple
Angle-regulating block group described in above embodiments is used for through identical adjusting block in the multiple angle-regulating block group to stator
Blade angle is adjusted.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with described
Subject to scope of protection of the claims.
