FIG. 6 is another schematic view of a rotor spider section.
the force-bearing structure of the rotor support section 110 shown in fig. 6 is not realized by adding the L-shaped rib plate 116 and the annular rib plate 115, but the structural rigidity is enhanced by adopting a detachable reinforcing ring which is assembled by a plurality of reinforcing ring sections 119. Compared with the lattice shape of the L-shaped rib plate 116 and the annular rib plate 115, the peripheral wall of the reinforcing ring section 119 is plate-shaped, so that when the reinforcing form of the reinforcing ring section 119 is adopted within a possible adjustment area and adjustment thickness range, the same or similar reinforcing effect as that of the reinforcing form of the L-shaped rib plate 116 and the annular rib plate 115 of the previous embodiment can be achieved by structurally ensuring the reinforcing mode through the combined action of the L-shaped rib plate 116 and the annular rib plate 115. The stiffening ring segments 119 are fixed by welding (the amount of welding may not be too large for subsequent disassembly) at the locations where the amount of yoke deformation of the spider segments 110 is large, and 1 spider segment 110 may correspond to one or more stiffening ring segments 119. After the rotor support sections 110 are joined, the adjacent reinforcement ring sections 119 at the rotor support joint are spot-welded together at the welding point 190, while ensuring that the adjacent reinforcement ring sections 119 do not contact at the welding point 190, so that the rotor support sections 110 are connected only by the first and second connection flanges 111, 112, or the rotor support sections 110 are connected only by the third and fourth connection flanges 121, 122.
it should be noted that the sealing grooves on the first connecting flange 111 of the rotor support section 110 and the third connecting flange 121 of the rotor cover section 110 may be designed as needed, and only the sealing requirements of the modular rotor may be satisfied without completely penetrating the entire contact surface.
After the rotor assembly is assembled with the stator and shafting as a single unit, the stiffener ring section 190 can be removed and the stiffener ring section 190 can be retained as desired.
