158 so engaged the shaft is received by a split aperture 220 formed in side edge 178 of the outer diameter platform a corresponding split aperture 222 is formed in side edge 176 that receives a portion of a shaft of a variable vane of an adjacent vane not shown the inner diameter platform incorporates a bearing 224 that receives distal end 226 of the shaft 202 in some embodiments bearing 224 can be configured as a cartridge bearing and or contain a spherical bearing it should be noted that by providing a spherical surface misalignment of the inner diameter and outer diameter platforms should not induce a bending moment on the on airfoil 154 as mentioned before multiple vanes typically are configured in an annular arrangement of vanes to form a vane assembly the vane assembly defines an annular gas flow path between the vanes and platforms multiple vanes similar in construction to vane 150 can be provided in such an assembly as such the annular arrangement includes alternating stationary and variable airfoils assembly detail of the embodiment of fig3 is shown in the schematic diagram of fig4 as shown in fig4 stationary portions of the vane are provided as an assembly 230 that.
