Background technique
At present, the blade angle-adjustable controlling device of gas turbine mainly contains simple rocking bar regulative mode, this device is the adjustment being carried out blade angle by rocking bar band moving vane, for the structure of simple rocking bar regulative mode, interlock ring not only will carry out circumferential movement, there is the axial motion of relative casing simultaneously, when therefore completing adjustment of blade angle, need larger space; This its complex structure of mode by rocking bar adjusting vane angle, the difficulty adding gas turbine installation and keep in repair, during interlock ring circumferential movement, mechanical wear is very fast, in addition, due to the drawback that adjusting vane angular range is little, then the situation of the adjustment of blade angle scope can not satisfying the demand larger.
Summary of the invention
The purpose of this utility model is to provide a kind of device adjusting casing blade angle, the problem that original controlling device complex structure, required adjustment movement space are comparatively large to solve, gas turbine I&M difficulty is comparatively large, regulating blade angle scope is less.
The technological scheme that the utility model adopts is: provide a kind of device adjusting casing blade angle, includes casing 1, self-locking nut 4, adjustable vane 3, bolt 5, interlock ring 8, spheroid 9, bolt 10 and plectrum 11.Described plectrum 11 one end is provided with ears structure, plectrum 11 is fixed on interlock ring 8 through the through hole on plectrum 11 by bolt 10, described spheroid 9 is connected with adjustable vane 3 by bolt 5, and spheroid 9 is arranged between the ears of plectrum 11, and the ears of the external diameter of spheroid 9 and plectrum 11 are tangent.When needs adjusting vane angle, interlock ring 8 only needs to do circumferential movement, and interlock ring 8 drives plectrum 11 to move, and plectrum 11 is stirred adjustable vane 3 by spheroid 9 and rotated, thus realizes the angular adjustment of adjustable vane 3.In adjustment process, interlock ring 8 only needs to do circumferential movement, saves adjustment space.
Alternatively, described interlock ring 8 is set to " U " type structure, interlock ring 8 connects the position of plectrum 11, is provided with roller bearing core 13 between two side, " U " type structure can alleviate the weight of interlock ring 8, and the effect of support is played in the two side of roller bearing core 13 pairs of interlock rings 8.
Alternatively, on the external diameter of described roller bearing core 13, cover has roller 12, and roller 12 external diameter two ends are provided with boss structure, the groove that two ends boss is formed is stuck on casing 1, when interlock ring 8 does circumferential movement, roller 12 rolls around roller bearing core 13, decreases the mechanical wear of interlock ring 8 and casing 1.
Alternatively, on casing 1 for adjustable vane 3 is installed through hole in can be provided with lining 14, lining 14 one end is provided with boss structure, and the two ends of lining 14 are also provided with pad 6, and lining 14 can reduce mechanical wear when adjustable vane 3 rotates and between casing 1.
Alternatively; lining 7 is provided with between described spheroid 9 and adjustable vane 3; the large external diameter of lining 7 is less than the sphere diameter of spheroid 9; lining 7 can prevent in blade adjustments process; interfere between plectrum 11 and adjustable vane 3; be provided with square washer 2 between self-locking nut 4 and adjustable vane 3, namely square washer 2 can protect adjustable vane 3 from wearing and tearing, again can retaining washer 6.
The beneficial effects of the utility model are, just can realize the regulatory function of blade angle by means of only the circumferential movement of interlock ring; Secondly, the utility model structure is simple, easy for installation, makes the regulation range of blade angle under same space condition, increases more than 1.5 times than original simple rocking bar regulative mode; The utility model also can be applicable in the machinery relevant to turbine structure adjustable vane such as space industry.In addition, the roller in the middle of interlock ring and roller bearing core coordinate cleverly makes the mechanical wear in movement process obtain obvious improvement.
