MULTILINE NONPLANETARY DOUBLE-STAGE GEARING Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: gearing has a body, coaxial driving and driven shafts with gears and intermediate gears of the first and second stages engages with them mounted on their supports and coupled to each other by intermediate shafts. Number of splines on spline shafts is different at opposite ends. Spline shafts are made for couping of device to them intended for their displacement. After installation of the first-line spline shafts, the second-line spline shafts are installed in succession with gearing loaded by normalized torque and rated axial force is applied to each spline shaft installed. In case of free axial displacement of one of spline shafts its angular position is changed, and operation of loading by torque and checking by axial force is repeated prior to assembly of all gearing lines, which ensures preset accuracy of power distribution over lines. EFFECT: enhanced efficiency. 2 cl, 1 dwg
