Abstract
A backlash reducing apparatus for a gearbox, the gearbox having a hollow bore and a shaft in the hollow bore, with the hollow bore having a counter-bore at each end includes: a first pair of tapered, interlocking rings engaging the shaft within the hollow bore at one end of the hollow bore; a second pair of tapered, interlocking rings engaging the shaft within the hollow bore at the opposite end of the hollow bore; and a fastener engaging the shaft and applying axial pressure to the first and second pairs of tapered, interlocking rings to thereby force the first and second pairs of tapered, interlocking rings against the shaft and the hollow bore. A method for reducing backlash in a gearbox, the gearbox having a hollow bore and a shaft in the hollow bore, consists of: engaging a first pair of tapered, interlocking rings against the shaft within the hollow bore at one end of the hollow bore; engaging a second pair of tapered, interlocking rings against the shaft within the hollow bore at the other end of the hollow bore; and applying axial pressure to the first and second pairs of tapered, interlocking rings to thereby force the first and second pairs of tapered, interlocking rings against the shaft and the hollow bore.
