DRIVE FOR HEDDLE FRAMES OF HEALD MACHINE Russian patent published in 2004 - IPC

FIELD: textile engineering.

SUBSTANCE: drive has drive shaft mounted in drive casing and connected through kinematic transmission with main shaft of weaving machine. Drive shaft carries planetary actuating clutches, each engageable through control lever with program device and through carrier, crown gear and pair of retainers with lever transmission to heddle frame. Number of planetary actuating clutches is equal to number of heddle frames. Crankshaft of lever transmission is mounted on carrier. Rotational shaft of crown gear retainer is fixed on drive casing and rotational shaft of carrier retainer is fixed on beam for vibration relative to drive shaft axis. Control lever is equipped with blocking mechanism for preventing planetary actuating clutches predetermined change-over phase from upsetting and for controlling maximal admissible operating parameters of drive.

EFFECT: increased efficiency and enhanced reliability in operation.
