摘要： A drill chuck has a chuck body, a holder body, and an outer sleeve surrounding the bodies, with jaws between them. A ring of teeth on one of the bodies can be engaged by a pawl angularly fixed on the other of the bodies. When engaged, the pawl and the array of teeth allow rotate relative to the chuck body in a tightening direction but not in a loosening direction. Respective interengaging stops on the other body and on the outer sleeve limit relative angular movement of the outer sleeve on the other body between a pair of angularly offset end positions. An inner control sleeve has a cam formation engageable with the pawl in only one of the end positions to hold the pawl in the freeing position. The pawl is biased by a spring in the other end position into the locking position.

摘要： A device for rotation of disc-shaped elements of different diameter, such as matrices for manufacturing audio and video discs. The device comprises a rotatable chuck (10) in which three arms (20) distributed evenly in the peripheral direction are pivotably mounted, the said arms having a radially outer stop element (22) for contact with an outer peripheral edge of a disc element inserted in the chuck. The chuck has a rotatably mounted central gearwheel (18) which is preloaded by means of tension spring elements (28) towards a rotational position in which the central gearwheel (18) tends to hold the arms (20) and their stop elements (22) in a pivoted-in position in the chuck. The arms (20) are synchronously pivotable towards a pivoted-out position counter to the action of the tension spring elements (28). The device comprises a retaining mechanism (30-40) which is configured to lock the rotation of the central gearwheel (18) relative to the base plate (16) when a predetermined speed of the chuck (10) is reached.

摘要： An agitator comprises a main body for supporting rotatably a rotary shaft, a chuck for connecting detachably an agitating rod with the rotary shaft, starting means for starting the rotation of the rotary shaft when the chuck is covered with a chuck cover, and locking means for locking rotary shaft when the chuck is not covered with the chuck cover. The chuck cover is removed from the main body when an external force larger than a predetermined value is applied to the chuck cover. The starting means comprises a permanent magnet provided on the outer periphery of a disk hub and a magnetic sensor provided on the main body so that an output is generated to start the driving source only when the chuck cover is moved to cover the chuck. The locking means comprises a hole formed in the rotary shaft, an eccentric cam to be rotated by the chuck cover, and a lock pin which is moved by the eccentric cam so as to be inserted into the hole of the rotary shaft when the chuck is not covered with the chuck cover. A universal joint comprises a cavity formed in a joint case, a planar plate fitted in the cavity, a spherical member arranged in the cavity so that it is held by a spherical surface receiving seat and a portion of the planar plate, and pressure means for pressing the planar plate toward the spherical surface receiving seat.

摘要： A lathe chuck has a chuck body centered on and rotatable about a main axis and formed with a plurality of radially extending jaw-guide grooves and, transverse to the grooves, with respective guide passages each in turn formed with an abutment. Respective jaws displaceable in the grooves each have at least one tooth exposed in the respective guide passage and respective control rods displaceable along the passages each have at least one tooth meshing with the tooth of the respective jaw. A control pin is axially displaceable in each rod between an extended position projecting into the respective jaw-guide groove and a retracted position. The control pins are displaced on engagement with the teeth of the respective jaws into the retracted positions. A latch pin is axially displaceable in each rod between an extended latching position engaging the respective abutment and preventing movement of the respective rod in the respective passage and a retracted position permitting such movement. A spring urges the pins into their extended positions, and a coupling member engaged between the pins displaces the respective latch pin into the respective retracted position on displacement of the control pin into its retracted position. Thus, when there is no jaw in the guide groove, the latch pin of the respective control rod latches same against movement in the respective passage.
