Abstract
The utility model proposes a kind of gas turbine drive axle anti-reverse mechanism.Combustion engine side flange assembly is provided with the mounting groove of circle distribution, anti-reverse ratchet, detent pin, ratchet spring, ratchet backing pin are arranged in groove, gas turbine drive axle and combustion engine side flange assembly by twisting drilling bolt, locking plate is connected, anti-reverse ratchet is provided with the hook tooth of regular distribution, upper cover plate, lower cover plate are connected with anti-reverse ratchet by screw, lock washer, pad, anti-reverse ratchet is provided with the detecting sensor of circle distribution, and anti-reverse ratchet is fixed on gas turbine drive shaft housing body by bolt, locking plate, step pin.The sour jujube of click is used to close principle, its anti-reverse-rotation structure is designed, and optimize its anti-reverse ratchet position of centre of gravity, make when the clockwise high speed rotating of gas turbine drive axle, by centrifugal forces affect, anti-reverse ratchet can not contact with anti-reverse ratchet, reduces noise, and wearing and tearing can not be caused to both, improve the working life of anti-reverse mechanism.
Description
technical field:
The utility model relates to gas turbine field, specifically a kind of gas turbine drive axle anti-reverse mechanism.
background technique:
Gas turbine is advanced power plant, have high efficiency, low stain, startup fast, be convenient to safeguard, the energy can the feature such as cascade utilization.When power system equipment is installed, because of artificial origin, often in installation process, gas turbine drive axle can be caused to reverse, or in drive system working procedure, be constantly vented because of during running, air flowing causes gas turbine drive axle system to reverse, so that harmful effect is caused to the tooth sealing configuration that closes of gas turbine inside, reduces life of equipment.
model utility content:
In order to solve the problem, the utility model devises a kind of sliding bearing for supporting connecting cylinder.
The technical solution of the utility model is: a kind of gas turbine drive axle anti-reverse mechanism, comprise combustion engine side flange assembly, combustion engine side flange assembly is provided with the mounting groove of circle distribution, anti-reverse ratchet, detent pin, ratchet spring, ratchet backing pin is arranged in groove, gas turbine drive axle and combustion engine side flange assembly are by twisting drilling bolt, locking plate connects, anti-reverse ratchet is provided with the hook tooth of regular distribution, upper cover plate, lower cover plate passes through screw, lock washer, pad is connected with anti-reverse ratchet, anti-reverse ratchet is provided with the detecting sensor of circle distribution, anti-reverse ratchet passes through bolt, locking plate, step pin is fixed on gas turbine drive shaft housing body.
The utility model has following beneficial effect: gas turbine anti-reverse mechanism of the present utility model, namely the ratchet sour jujube cooperation of ratchet is used to use, when gas turbine drive axle causes reversion because of other reasons, its reversion is limited, compare with current other anti-reverse mechanism, the gas turbine anti-reverse mechanism of the utility model research, the sour jujube of click is used to close principle, its anti-reverse-rotation structure is designed, and optimize its anti-reverse ratchet position of centre of gravity, make when the clockwise high speed rotating of gas turbine drive axle, by centrifugal forces affect, anti-reverse ratchet can not contact with anti-reverse ratchet, reduce the noise because frequent impact produces, and comparatively galling can not be caused to both, improve the working life of anti-reverse mechanism.
accompanying drawing illustrates:
Fig. 1 is the utility model exemplary construction sectional drawing.
Fig. 2 is Fig. 1 sectional view.
1-combustion engine side flange assembly in figure, the anti-reverse ratchet of 2-, 3-ratchet backing pin, 4-detent pin, 5-ratchet spring, the anti-reverse ratchet of 6-, 7-bolt, 8-locking plate, 9-screw, 10-lock washer, 11-pad, 12-step pin, 13-upper cover plate, 14-lower cover plate, 15-twists drilling bolt, 16-detecting sensor, 17-gas turbine drive shaft assembly, 18-closes tooth sealing, 19-combustion engine frame.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 composition graphs 2, a kind of gas turbine drive axle anti-reverse mechanism, comprise combustion engine side flange assembly 1, combustion engine side flange assembly 1 is provided with the mounting groove of circle distribution, anti-reverse ratchet 6, detent pin 3, ratchet spring 5, ratchet backing pin 4 is arranged in groove, gas turbine drive axle 17 and combustion engine side flange assembly 1 are by twisting drilling bolt 15, locking plate 8 connects, anti-reverse ratchet 2 is provided with the hook tooth of regular distribution, upper cover plate 13, lower cover plate logical 14 crosses screw 9, lock washer 10, pad 11 is connected with anti-reverse ratchet 2, anti-reverse ratchet 2 is provided with the detecting sensor 16 of circle distribution, anti-reverse ratchet 2 is by bolt 7, locking plate 8, step pin 12 is fixed on gas turbine drive shaft housing body 19.
The active force that anti-reverse ratchet 6 on combustion engine side flange assembly 1 is subject to ratchet spring 5 upwards lifts, ratchet backing pin 3 carries out spacing to anti-reverse ratchet 6, make when gas turbine drive axle rotates backward, anti-reverse ratchet 6 can carry out sour jujube cooperation use at the anti-reverse ratchet 2 of gas turbine drive shaft housing body with connecting firmly, therefore, realize the counter-rotational restriction of gas turbine drive axle.When gas turbine drive axle presses forward (clockwise) high rotational speed, the anti-reverse ratchet 6 on combustion engine side flange assembly does not contact with anti-reverse ratchet 2 inner circumference, and sour jujube is not closed, and does not affect the normal work of gas turbine.
Anti-reverse mechanism peripheral assembly: detecting sensor 16, gas turbine drive shaft assembly 17, close tooth sealing 18, gas turbine drive shaft housing body 19.
