Abstract: An improved method of holding a key (20) in a keyway (31) includes the steps of: forming an elongated keyway in the member, the member having at least one sharp corner (34) facing into the keyway adjacent either end thereof; forming a key (20) to fit in the keyway, the key being so dimensioned, proportioned and configured that the part of the key immediately adjacent each sharp corner will be recessed with respect to the surface of the member at the corner; placing the key in the keyway; and plastically deforming portions (40) of the member at the sharp corners into the keyway so as to permanently hold the key in the keyway.

Abstract: A spindle assembly (20) adapted to be mounted on the rotatable head (21) of a Davenport® multi-spindle automatic screw machine, broadly includes a one-piece outer spindle (38), a seal member (39), a front bearing assembly (40A, 40B, 40C), a front bearing retainer nut (41) forming with the seal member a tortuous passageway (85), a two-part spacer (37), a rear bearing assembly (44A, 44B), and a rear bearing retainer nut (45).

Abstract: An improved spindle assembly (23) is adapted to be mounted in an opening (22) provided on a rotatable head (20) of a multi-spindle machine tool. The improved spindle assembly includes a tubular main spindle part (26) that is adapted to be inserted into the head opening and having a first abutment surface (42), a bearing retainer (27) adapted to be threaded into engagement with the head and having a second abutment surface (55) arranged to face toward the first abutment surface, at least one bearing (28) positioned radially between the head and spindle main part, and being arranged axially between the first and second abutment surfaces, and a retaining nut (29) adapted to be threaded into engagement with the spindle main part so as to form therewith an assembled spindle.
