OPERATING MECHANISM OF NUCLEAR REACTOR CONTROL RODS FOR SPACE POWER PLANT Russian patent published in 1998 - IPC

FIELD: space nuclear reactors. SUBSTANCE: operating mechanism of control rods arranged over circumference in side reflector has servodrives, gear-type distributor, and links for control rods; distributor has antifriction bearings, housings with stops, shafts with projections, controlled couplings, and is made in the form of annular body. Inner wall of annular body functions as inner cage of antifriction bearing whose outer cage is formed by distributing gear which is in mesh with gears fitted onto output shafts coupled with control rods which form groups. Antifriction bearings are roller bearings with roller length greater than width of distributing gear ring. Connected to one of shafts of group is servodrive whose shaft or one of gears of group is provided with projection and body has stop. EFFECT: improved design. 2 cl, 9 dwg
