METHOD OF ASSEMBLING OF GEAR TRAIN Russian patent published in 1997 - IPC

FIELD: mechanical engineering; engines; gear train for transmission of torque from crankshaft to camshafts. SUBSTANCE: method comes to successively fitting gear wheels and gears onto corresponding shafts and relative orientation of train members forming splined connection. Relative orientation of members forming spline connection 4 is carried out by engaging driven gear 3 and driving gear 1 by selecting the position of driven gear 3 on driven shaft 5 with no backlash in meshing. This is done by turning driven shaft 5 relative to driven gear 3 through angle of 380 degrees ((Z_s×Z_t)) where Z_s is number of splines on driven shaft and driven gear and Z_t is number of teeth of driven gear on condition that if Z_s is even number, then Z_t is odd number and vice versa. EFFECT: enhanced reliability of operation. 1 dwg
