摘要
FIELD: mechanical engineering, in particular, stretching equipment for belt drive.;SUBSTANCE: stretching apparatus has first pulley 34, drive belt 24, first lever for supporting of first pulley 34, first bearing for mounting of first pulley, second pulley 35, second lever for supporting of second pulley 35, and second bearing for second pulley. Stretching apparatus is additionally equipped with spacer attached to first spacer attachment point and second spacer attachment point. First lever is positioned for rotation in first pivot joint. Second lever is positioned for rotation in second pivot joint. First pulley 34 and first spacer attachment point are offset crosswise relative to first pivot joint and are substantially balanced as to parasitic torque on first pivot joint.;EFFECT: increased service life and reduced wearing of bearings owing to utilization of two pulleys.;26 cl, 8 dwg
