The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in FIG. 1 to 3, a kind of device of installing and decomposing non-bolted joint baffle plate, comprises base 2, is provided with back-up block 1 and angle alignment pin 6 on described base 2; Above base 2, be provided with upper cover plate 12, 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, between described main shaft 4 and upper cover plate 12, is provided with bearing 10, on the main shaft 4 below upper cover plate 12, is provided with and holds out against nut 9; On described base 2, be provided with set bolt 5, on described upper cover plate 12, be provided with baffle limiting pin 7.
For the ease of rotary upper cover plate 12, on one end of described upper cover plate 12, be provided with handle 13; On the other end of described upper cover plate 12, be provided with the spanner seat 8 with spanner installing hole 14.
For the ease of observing, on described upper cover plate 12, be provided with observation window 15.
The turbine disk and the baffle plate of turbine rotor of now take is example, and once mounting of the present invention and decomposable process are described:
Described baffle plate 16 is thin-wall annular part, on the mounting edge of core wheel position, there are 9 place's lugs, and on each lug, are all 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 coordinates with baffle plate 16, has 9 place's hook grooves in turbine card, and wherein 9 place's hook grooves coordinate with 9 lugs of baffle plate 16, and baffle plate 16 is carried out to axial location; After 9 place's hook grooves align with 9 place's lug end faces of baffle plate 16, fixture block is installed, baffle plate 16 is carried out to circumferential stop, and with latch to fixture block stop.Because baffle plate 16 and the turbine disk 17 axially and radially all exist a certain amount of interference, its assemble sequence is first baffle plate 16 to be applied to 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 pack spacer pin into, prevent 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, controls.
During installation, first, the turbine disk of turbine rotor 17 is placed on the back-up block 1 of base 2 above upward, and will in the hole of the 6 insertion turbine disk 17 rear mounting edges of two angle alignment pins on base 2, carries out angle location, prevent that the turbine disk 17 from rotating.By the nut 11 on rotary main shaft 4, press cover plate 12 downwards, make 12 pairs of baffle plates 16 of upper cover plate apply axial pressure, make baffle plate 16 produce 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 by 3 baffle limiting pins 7, is close to lug one side of 16 times mounting edges of baffle plate; The strength that can bear is like this larger, also can not cause damage to baffle plate 16.Then, by N in Fig. 3, to the nut 11 on (clockwise) rotary main shaft 4, by M in figure, to (downwards), press cover plate 12, thereby drive baffle plate 16 to produce axial elasticities distortion; Meanwhile, by the position of the 16 times mounting edge lugs of observation window 15 viewing hood on upper cover plate 12 and the hook groove on the turbine disk 17, check and whether be seated; When baffle plate 16 can rotate, the interior assembly wrench of spanner installing hole 14 at spanner seat 8, utilize spanner and handle 13 rotary upper cover plates 12, drive baffle plate 16 to rotate, 16 times mounting edge lugs of baffle plate are entered in the hook groove on the turbine disk 17, until the limit pin hole of 16 times mounting edge lugs of baffle plate and the turbine disk 17 are risen to the bait, the limit pin hole of groove aligns, even the alignment of the end face of lug and hook groove; Press in Fig. 3 N rotating nut 11 round about, take off upper cover plate 12, mounting limit pin in limit pin hole, installation.
During decomposition, only need to press direction rotation upper cover plate 12 contrary while installing.
When rotary resistance is large especially, can base 2 be installed on square chest by two set bolts 5, in case locking apparatus unitary rotation.
