摘要： A chuck assembly (16) for use with a power driver (10) having a forward end (34), a housing (12), a gearbox (26), and a rotating spindle (30) extending therefrom includes a separate interface plate (24). The interface plate (24) is received by and is rotationally fixed to the forward end (34) and includes a forward face (125) defining a center opening (66) and a forward-facing rotational stop (62, 64). The spindle (30) extends through the center opening (66) to receive a chuck. The chuck includes a body (110) having a nose (122) and a tail (124), the tail (124) being configured to rotate with the spindle (30), and the nose (122) including an axial bore (126). Chuck jaws (118) are received by the body (110) and movable toward and away from the chuck axis (31). A bracket (70) is disposed about the body (110) and extends rearward of the tail (124). The bracket (70) defines a rearward surface (71) engaging the stop (62, 64) to rotationally fix the bracket (70) to the interface plate (24).

摘要： Chuck (20) for use with a driver having a rotatable shaft, including a body (26) and jaws (28) slidably positioned in angled passageways (30) formed in the body (26). The chuck (20) further includes a nut (60) rotatably mounted relative to the body (26) and in engagement with threads (62) on the jaws (60). A generally cylindrical sleeve member (22) is disposed in driving engagement with the nut (60) and overlying the nose section (23) of the body (26) so that when the sleeve member (22) is rotated with respect to the body (26), the jaws (28) will be moved thereby to grip the shank of a tool. A pawl member (80) is biased to engage the sleeve member (22) and is disposed selectively rotatably with respect to the body (26). When the nut (60) is tightened, the pawl member (80) can be disposed to become nonrotatable with respect to the body (26) and restrains the nut (60) from loosening during vibration of the chuck (20) in use.

摘要： A tool driver includes a housing (30) and a rotatable drive shaft (28). A chuck (10) for holding the tool includes a generally cylindrical body (12) having a nose section (80) and a tail section (82). Jaws (16) are slidably positioned in angularly disposed passageways (42) in the body (12). Each jaw (16) has a jaw face (34) and threads (36) formed thereon. A nut (18) is in operative communication with the drive shaft (28) so that the drive shaft (28) rotationally drives the nut (18). The nut (18) engages the jaw threads (36) so that rotation of the nut (18) moves the jaws (16) axially within the passageways (42). A locking mechanism (20, 48) is mounted to at least one of the housing (30) and the body (12) and is selectively actuatable to first and second operative positions. In the first position, the locking mechanism (20, 48) rotationally locks the housing (30) and the body (12) with respect to each other. In the second, it permits relative rotation between the body (12) and the housing (30).

摘要： A chuck (10) transmits the rotational force of an operating ring (17) fitted over a body (11) to a nut ring (15), opening and closing the jaws (12). An input ring (18) is fitted into the inner surface of the operating ring (17) opposing the nut ring (15), and a thrust bearing (22) between the inner side of the input ring (18) and the body (11) positions a ball holder (21) on the body (11) side, forming a ball thread (23) between the inner surface of the input ring (18) and the outer surface of the nut ring (15), which feeds the nut ring (15) in the direction of thrust by balls (27) held in a retainer (26) through the rotation of the input ring (18) in the clamping direction. An inner edge of the nut ring (15) is engaged with the inner surface of the ball holder (21), and a return spring (30) between the operating ring (17) and the nut ring (15) returns the nut ring (15) when the clamping load is released from the nut ring (15).

摘要： A chuck (10) for use with a manual or power driver having a rotatable drive shaft. The chuck includes a generally cylindrical body member (16) with a nose section (20) and a tail section (22). The tail section has an axial bore (26) formed therein to mate with the drive shaft of the driver, and the nose section has an axial bore (24) therein and a plurality of annularly disposed passageways (30) formed therethrough and intersecting the axial bore for receipt of a plurality of jaws (18) slidably positioned therein. The chuck further includes a generally cylindrical front sleeve member (12) overlaying the nose section and rotatable with respect thereto. The front sleeve member includes a threaded nut portion (36) integral therewith and in engagement with the threads on the jaws such that when the front sleeve member is rotated with respect to the body member, the jaws will be advanced or retracted, depending on the direction of rotation.

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). A clutch or torque limiting mechanism is provided to limit the tightening torque to a predetermined value while the loosening torque may be limited or unlimited. The front sleeve (12), and rear sleeve (14), if used, may be formed from a structural plastic to reduce manufacturing costs. The front sleeve (12) is located with respect to the nose section (20) of the body (16) by a press-fitted retainer disc (84).

摘要： The chuck (10) includes a slitted body (25) with an axial bore (20) that holds the tool shank (23) during rotation of the chuck (10). A gripping sleeve (50) applies compressive pressure via cam elements (36) to reduce the diameter of the axial bore (20). A spring biased locking sleeve (60) can activate locking elements (61) to lock the gripping sleeve (50) to the body member (25) in the locked position. An engagement mechanism (14) connects the chuck (10) to a drive spindle and also has a mounting mechanism (11) for facilitating automated mounting of the chuck (10) to a drive spindle.
