Non-impact keyless chuck

摘要

A non-impact keyless chuck suitable for use with manual or powered drivers is disclosed. The chuck comprises a body (16) having a relatively fine thread and a plurality of slidable jaws (18), which may be identical, driven by the rotatable nut (38). An anti-friction bearing (48) is disposed between the rotatable nut (38) and a bearing thrust ring (50) mounted on the body (16). The front sleeve (12), and rear sleeve (14), if used, may be formed from a structural plastic to reduce manufacturing costs. The nut (38) has axially directed serrations formed around its circumferential edge and adapted for press fitting of the front sleeve.
