To a question on function of differential in adjustment tooth milling machine

Clause states a technique of adjustment of a circuit of division tooth milling machine with the differential mechanism. This summing mechanism is applied to reception by independent cinematicsing of adjustment on a corner of an inclination tooths thread of a wheel. In this mechanismthe addition of two movements in one under the formula Villisa is analyzed, with the purpose of reception of the transfer relation of unit of adjustment of a circuit of division. Two widespread types of differential mechanisms are considered.
