machine for the adaptation for lapping for the government or for the functional control of land available conjugated gears

摘要

For a machine for running pairs of gears together, e.g., for lapping or testing one pair at a time, there is provided an incoming magazine, an outgoing magazine, a conveyor device which moves gear pairs toward the front of the incoming magazine; a conveyor device which moves gear pairs toward the back of the outgoing magazine; a transfer device which moves two pairs of gears across the machine at once: taking one pair from the machine's work station and another from the front of the incoming magazine and shifting these pairs, respectively, to the front of the outgoing magazine (or to a reject chute) and the machine's work station. The gears are oriented in the incoming magazine so they will mesh when mounted at the work station. The server is responsive to tests performed at the work station to reject and replace any damaged or improperly paired gears or any gear pair improperly installed at the work station and to indicate the reaons for rejection on a register which shifts as additional pairs are rejected so the machine operator can quickly discern which gear pair was rejected for which reason. A telescoping cover encloses the work station during the lapping operation to prevent contamination of the transfer mechanism.
