Torque transmission drive shaft - operates between centrally rotating driven shaft and eccentrically rotating drive pin, using sections plugged together

摘要

The drive shaft (19) for transmitting torque between a centrally rotating driven shaft of a motor and an eccentrically rotating drive pin of an eccentric screw-pump consists of several shaft-sections (20) joined by plug-in connections. The plug connections have tolerances allowing the shaft sections (20) to move in any lengthwise plane. The identical shaft sections each have one insertion part, and one holder part. USE/ADVANTAGE - The drive shaft is more durable and has a reduced min. distance between the motor and the drive-pin of the rotor.
