UNIT OF RATCHET FREE WHEEL MECHANISMS Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: unit has unmovable housing, ratchet wheels, dogs, reactor, and output shaft, which are arranged concentrically and form housing and output free-wheel mechanisms. The dogs are mounted on the inner and outer sides of the reactor. The ratchet wheel of the housing free-wheel mechanism has teeth of outer engagement, is connected with the unmovable housing, and engages the dogs of the inner set of the reactor. The ratchet wheel of the output free-wheel mechanism has teeth for inner engagement, is mounted on the output shaft, and engages the dogs of the outer set of the reactor. The reactor dogs are made for permitting their affecting by the centrifugal and tangential forces which occur when the reactor rotates. These forces press the dogs of the outer set to the teeth of the ratchet wheel of the output mechanism during the direct pulse and press the dogs of the inner set to the teeth of the ratchet wheel of the housing mechanism during the back pulse.

EFFECT: simplified design and enhanced reliability.
