Abstract
The utility model relates to a locking device, concretely relates to locking device of blade locking plate. The technical solution of the privacy body weight scale is characterized in tha, including hex nut and screw rod, hex nut with the screw rod passes through thread connection, the screw rod end is equipped with a tang, with listrium cooperation under the blade, hex nut with locking is implemented to two blade locking plates inserting between blade and rotor dish tongue -and -groove simultaneously to the screw rod. The utility model discloses the locking work of blade locking plate is accomplished in the realization in the narrow and small space under set shaft group state, not only shortened assembly period, has also improved blade locking plate locking qualification rate, has kept the crude balanced state of rotor, has reduced the vibration risk of taking a trial run.
Description
Technical field
The utility model relates to a kind of locking device, is specifically related to a kind of locking device of blade locking plate.
Background technique
At present in aeroengine and gas turbine field, the progression of rotor is more, and the operating space between adjacent two-stage dish is narrow.When blade locking plate is installed between blade and rotor disk tongue-and-groove, need to decompose after the rotor initial balance not with blade completes, under single-deck state, adopt hard object to knock the locking method assembling of blade locking plate, finally carry out dish axle again and connect and final balance.This method easily causes locking plate bending part to crack defect, and locking plate locking up-to-standard rate is low, and assembly period is long, the more important thing is the state of equilibrium destroying rotor original, adds test run vibration risk.
Model utility content
The utility model provides a kind of locking device of blade locking plate, realize the locking work completing blade locking plate in the small space under dish shaft assembly state, not only shorten assembly period, also improve the tight up-to-standard rate of blade lock mortice lock, maintain the state of equilibrium of rotor original, reduce test run vibration risk.
The utility model is a kind of locking device of blade locking plate, comprises hexagon nut and screw rod, and described hexagon nut and described screw rod pass through scyewed joint; Described screw end head is provided with place's seam, coordinates with blade inframarginal; Described hexagon nut and described screw rod are implemented to lock to two the blade locking plates be inserted between blade and rotor disk tongue-and-groove simultaneously.
The locking device of described blade locking plate, utilizes spanner to turn described hexagon nut and implements locking to blade locking plate.
The locking device of blade locking plate of the present utility model carries out last blade locking work when coiling shaft assembly and connecting, the wherein hexagon nut of scyewed joint and screw rod, turn their generations by spanner to move to axial slowly, locking device two ends withstand on the blade locking plate bending part of two-stage dish assembly respectively, complete the locking work of two-stage blade locking plate simultaneously.The utility model not only maintain rotor original state of equilibrium, reduce test run vibration risk, and decrease the labor intensity of workman, reduce the difficulty of operation, improve working efficiency, shorten assembly period, and structure be simple.
Accompanying drawing explanation
Fig. 1 is the locking device schematic diagram of blade locking plate;
Fig. 2 is the blade locking plate schematic diagram of one end bending;
Fig. 3 is the rotor structure schematic diagram with two-stage dish assembly;
Fig. 4 is that the locking device of blade locking plate is implemented to lock schematic diagram to two the blade locking plates be inserted between blade and rotor disk tongue-and-groove simultaneously.
Embodiment
As shown in figures 1-4, a kind of locking device of blade locking plate, comprises hexagon nut 2 and screw rod 1, and described hexagon nut 2 and described screw rod 1 pass through scyewed joint; Described screw rod 1 termination is provided with place's seam 3, coordinates with blade inframarginal; Utilize spanner to turn described hexagon nut 2 makes described hexagon nut 2 and described screw rod 1 implement to lock to two the blade locking plates 4 be inserted between blade and rotor disk tongue-and-groove simultaneously.
Working procedure is as follows: primary rotor dish 5 and secondary rotor dish 6 are installed as component states with main shaft 9, first clamp angle certain for blade locking plate 4 bending with locking plate, then together with hexagon nut 2 being screwed in screw rod 1, according to the gap adjustment overall length between primary rotor dish 5 and secondary rotor dish 6, the two ends of hexagon nut 2 and screw rod 1 are made to withstand on two blade locking plates 4 respectively, the head of hexagon nut 2 is tightened finally by spanner, compress two the blade locking plates 4 be inserted between blade and rotor disk tongue-and-groove simultaneously, realize the locking to primary rotor blade 7 and secondary rotor blade 8.
Claims (2)
1. a locking device for blade locking plate, is characterized in that, comprises hexagon nut and screw rod, and described hexagon nut and described screw rod pass through scyewed joint; Described screw end head is provided with place's seam, coordinates with blade inframarginal; Described hexagon nut and described screw rod are implemented to lock to two the blade locking plates be inserted between blade and rotor disk tongue-and-groove simultaneously.
2. the locking device of blade locking plate according to claim 1, is characterized in that, utilizes spanner to turn described hexagon nut and implements locking to blade locking plate.
