Technical field
The present invention relates to a kind of locking disk auxiliary device, fastening system and locking method that is used to realize the axle connection.
Background technique
Between the main shaft and gearbox input shaft of wind power generating set, need closely cooperate by locking plate, to reach good drive connection, as shown in Figure 1, the function of locking plate is the requirement that main shaft 2 and gearbox input shaft 1 is reached transmitting torque by its taper fit.Locking plate mainly is made up of external conical sleeve 31, inner conical drogue 32 and high-strength bolt 33, keeps inner conical drogue 31 motionless in when assembling, 33 external conical sleeve 31 is moved to regulation moment along the conical surface by tighting a bolt.
Locking plate assembling at present mainly be by torque spanner successively or symmetry tighten each bolts 33, when tighting a bolt for external conical sleeve end face height difference h in guaranteeing in the specified altitude scope, moment can not once be screwed to specified value when tightening, the one, be easy to generate height difference h and do not reach specified value, the 2nd, the bolt strained excessive easy generation fracture of part, so moment of torsion increases gradually, when reaching this value Deng a circle Bolt Torque, whether the measuring height difference meets the demands, as not meeting the demands, then correct and can continue to increase moment after height difference reaches specified value, repetitive operation always is to reaching regulation moment and height difference; Correct back h value as height difference and throw away and can not reach requirement, the whole dismounting locking plate of palpus is reinstalled.This kind mounting type needs great amount of manpower and a large amount of time, and assembling a cover usually needed 8-48 hour and can assemble more than 4 people, brought difficulty to mass.
Summary of the invention
The present invention has overcome above-mentioned shortcoming, and a kind of simple in structure, easy-to-install locking disk auxiliary device, fastening system and locking method are provided.
The present invention solves the technological scheme that its technical problem takes: a kind of locking plate locking auxiliary device, comprise oil hydraulic cylinder and the hydraulic station that links to each other with described oil hydraulic cylinder through high-pressure oil pipe, described oil hydraulic cylinder evenly is arranged on the end face and the circumference between support of locking plate.
Be provided with backing plate between the end face of described oil hydraulic cylinder and locking plate.
The end face of described locking plate is the end face of inner conical drogue or external conical sleeve.
A kind of fastening system comprises locking plate and above-mentioned locking auxiliary device.
A kind of locking plate locking method comprises
Be contained in external conical sleeve, inner conical drogue on the gearbox input shaft respectively;

Startup connects the hydraulic station of oil hydraulic cylinder by high-pressure oil pipe, and regulates the pressure of hydraulic station;
Bolt is inserted inner conical drogue and external conical sleeve, and tighten;
With oil hydraulic cylinder release and dismounting.
Place the step between inside/outside tapered sleeve and the support to be specially oil hydraulic cylinder, place pad on the backing plate on the inside/outside tapered sleeve at oil hydraulic cylinder one end, the other end places in the support.
After step, also comprise the screw-down torque of checking bolt with the torque spanner of regulation with oil hydraulic cylinder release and dismounting.
The present invention provides the power of opposite direction for inside and outside tapered sleeve by oil hydraulic cylinder, keeps whole end force even, realizes highly consistently, adopts apparatus of the present invention and method can realize quick mounting, saves time, manpower, can save cost greatly.
Description of drawings
Fig. 1 is the structural representation of existing locking plate;
Fig. 2 is a structural representation of the present invention.
Embodiment
As shown in Figure 2, be used as the fastening system that electric machine main shaft and gearbox input shaft interfix, comprise by external conical sleeve 31, inner conical drogue 32 and high-strength bolt 33 form locking plate, also comprise the locking auxiliary device that constitutes by oil hydraulic cylinder 5, backing plate 6, high-pressure oil pipe 7 and hydraulic station 8, described oil hydraulic cylinder 5 (also being hydraulic jack) is arranged on external conical sleeve 31 and one and supports between 4, and it is on the circumference in axle center that described oil hydraulic cylinder 5 is evenly arranged in described main shaft, wherein, can be with the described support 4 of the outer side wall of gear-box.Described oil hydraulic cylinder 5 is connected to described hydraulic station 8 through high-pressure oil pipe 7, and described backing plate 6 is arranged between described oil hydraulic cylinder 5 and the external conical sleeve 31.
In the installation process, earlier with external conical sleeve 31, inner conical drogue 32 is contained in respectively on the gearbox input shaft 1, backing plate 6 is positioned on external conical sleeve 31 end faces, oil hydraulic cylinder 5 one ends are placed on the backing plate, the other end places in the support, quantity is that one or several symmetry is uniform, be bound up on each high-pressure oil pipe 7 of 5 of hydraulic station 8 and oil hydraulic cylinders, by starting hydraulic station 8 and regulating the pressure of hydraulic station 8, fluid promotes external conical sleeve 31 forward along inner conical surface 32 by oil hydraulic cylinder 5, after reaching authorized pressure or height difference, external conical sleeve in all high-strength bolts 33 are inserted, and tighten with electric wrench and to get final product; Release and with oil hydraulic cylinder 5 dismounting is gradually then checked the screw-down torque of bolt with the torque spanner of regulation, satisfies regulation moment end then is installed.
In addition, described support 4 can adopt other relatively-stationary planes to realize, also can be arranged at inner conical drogue one side, and oil hydraulic cylinder is arranged between inner conical drogue and the support, and inner conical drogue is promoted to the external conical sleeve direction.
