FIELD: machine building.
SUBSTANCE: group of inventions relates to reduction gears. Method comprises making the following steps: measuring crankcase crash, calculating a first angular play induced at the level of each intermediate gear, based on measured factory defects, further, evaluation of the second angular play induced at the level of each intermediate gear by crankcase deformations during reduction of the threshold torque by the reduction gear, then total angular play is calculated based on first angular play and second angular play and two idle gears are selected, having phase difference compensating for common angular play. Also disclosed is a reduction gear made by this method.
EFFECT: production of reduction gear with reduced weight and reduced dimensions.
