The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Such as Fig. 1～shown in Figure 3, a kind of device of installing and decomposing the non-bolted joint baffle plate comprises base 2, is provided with back-up block 1 and angle alignment pin 6 at described base 2; Be provided with upper cover plate 12 above base 2, described upper cover plate 12 is connected with base 2 by main shaft 4; One end of main shaft 4 is fixedly connected with by screw 3 with base 2, and the other end is connected with nut 11 by upper cover plate 12, is provided with bearing 10 between described main shaft 4 and upper cover plate 12, and the main shaft 4 below upper cover plate 12 is provided with and holds out against nut 9; Be provided with set bolt 5 at described base 2, be provided with baffle limiting pin 7 at described upper cover plate 12.
For the ease of rotary upper cover plate 12, be provided with handle 13 at an end of described upper cover plate 12; The other end at described upper cover plate 12 is provided with the spanner seat 8 with spanner installing hole 14.
For the ease of observing, be provided with observation window 15 at described upper cover plate 12.
Now take the turbine disk of turbine rotor and baffle plate as example, once mounting of the present invention and decomposable process are described:
Described baffle plate 16 is thin-wall annular part, 9 place's lugs are arranged on the mounting edge of core wheel position, and on each lug, all be processed with the hole of a Ф 3.2mm, be used for installing balancing weight and latch, to reach the requirement of radial stop and adjustment amount of unbalance, it is the baffle arrangement of non-bolted joint.
The turbine disk 17 of described turbine rotor cooperates with baffle plate 16, and 9 place's hook grooves are arranged on the turbine card, and wherein 9 place's hook grooves cooperate with 9 lugs of baffle plate 16, and baffle plate 16 is carried out axial location; 9 place's hook grooves are installed fixture block with after 9 place's lug end faces of baffle plate 16 align, and baffle plate 16 is carried out circumferential stop, and with latch to fixture block stop.Because axially and radially all there is a certain amount of interference in baffle plate 16 with the turbine disk 17, its assemble sequence is first baffle plate 16 to be applied axial compressive force, then it is rotated, the lug of baffle plate 16 is packed in the hook groove of the turbine disk 17, make the end face alignment of lug and hook groove, then the spacer pin of packing into prevents mutual rotation.
The present invention selects a wide narrow endless belt of the lower mounting edge 1mm of baffle plate 16, and as the seal face of frock, the axial stroke of frock is exactly the deflection of baffle plate 16, than being easier to control.
During installation, at first, on the back-up block 1 that is placed on base 2 that faces up before the turbine disk 17 with turbine rotor, and carry out the angle location in the hole with two angle alignment pins, the 6 insertion turbine disks, the 17 rear mounting edges on the base 2, prevent that the turbine disk 17 from rotating.Press cover plate 12 downwards by the nut 11 on the rotary main shaft 4, make 12 pairs of baffle plates 16 of upper cover plate apply axial pressure, make baffle plate 16 produce the axial elasticity distortion, the mounting edge of upper cover plate 12 is pressed onto on the lug of 16 times mounting edges of baffle plate, and is close to lug one side of 16 times mounting edges of baffle plate by 3 baffle limiting pins 7; The strength that can bear like this is larger, also can be to baffle plate 16 injuries.Then, press the nut 11 on (clockwise) rotary main shaft 4 of N among Fig. 3, press cover plate 12 by M among the figure to (downwards), produce the axial elasticities distortion thereby drive baffle plate 16; Simultaneously, by the position of the 16 times mounting edge lugs of observation window 15 viewing hoods on the upper cover plate 12 and the hook groove on the turbine disk 17, check whether be seated; When baffle plate 16 can rotate, spanner installing hole 14 interior assembly wrench at spanner seat 8, utilize spanner and handle 13 rotary upper cover plates 12, driving baffle plate 16 rotates, 16 times mounting edge lugs of baffle plate are entered in the hook groove on the turbine disk 17, the limit pin hole of groove aligns until the limit pin hole of 16 times mounting edge lugs of baffle plate and the turbine disk 17 are risen to the bait, even the alignment of the end face of lug and hook groove; Press among Fig. 3 round about rotating nut 11 of N, take off upper cover plate 12, mounting limit pin in limit pin hole, installation.
During decomposition, opposite direction rotation upper cover plate 12 gets final product when only needing by installation.
When rotary resistance is large especially, can base 2 be installed on the square chest by two set bolts 5, in case the locking apparatus unitary rotation.
