Abstract
The invention is an improved clutching means for driving between axially aligned parts and is particularly adaptable in tapping attachments having free axial float. The clutch drive means is in the form of a sleeve having a ball race carrying driving balls interposed between axial splines on a driving part and on the driven splindle part in both direct and reverse drive. A torque release clutch is provided. It acts on a drive member through which drive is transmitted in both direct and reverse drive so that it will release in the event of excessive torque in either direct or reverse drive.
Claims6
In a coupling means for transmitting torque, in combination, a means for imparting rotary drive, a driven member, direct drive means for driving the member and reverse drive means for driving the member in the opposite direction, a clutch means for shifting between direct and reverse drive, a driving sleeve which is driven by the drive means and having a part positioned to be engaged for direct drive and a second part which engages the reverse drive means, a torque release clutch interposed between the driving means and said driving sleeve whereby the said torque release clutch will respond to excessive torque load either in direct drive or reverse drive.
