The mechanism for cable winding comprises a drive means to a spindle carrying a cable reel, having a spur gear the output member of which is axially displaceable in relation to the input member while still permitting torque to be transmitted by the spur gear. The spur gear applies torque to the spindle via a slippable friction clutch the input member of which is biassed against the output member by axial displacement of a shaft carrying the output member of the spur gear; the shaft displacement being taken up by axial displacement of the output member. The spur gear is efficient in transmitting torque and avoids difficulties due to under or overheating of the lubricant. The clutch is a simple but convenient means of transmitting the torque delivered by the spur gear to the spindle. |
