摘要： A drill chuck has a chuck body centered on a longitudinal axis and formed with a plurality of forwardly open angled guides spaced about the axis. Respective jaws displaceable along the guides in the chuck body are each formed with a row of teeth. A tightening sleeve rotatably surrounding the body is axially fixed to a ring rotatable on the body about the axis and formed with a screwthread meshing with the teeth of the jaws so that rotation of the sleeve and ring in one direction moves the jaws radially together and opposite rotation moves them radially apart, A first axially elastically deformable spring seated in the chuck body bears axially forward on the ring, and a second axially elastically deformable spring seated in the chuck body bears axially rearward on the sleeve.

摘要： A drill chuck has a body formed with an axially forwardly open tool recess and holding a plurality of tool-gripping jaws. A socket formed with an axially forwardly open polygonal-section seat is nonrotatable in a seat of the chuck body and axially displaceable in the chuck body into and out of a tool-releasing position. A latch is radially displaceable in the socket in the tool-releasing position of the socket between an inner retaining position projecting radially into the seat and an outer freeing position clear of the seat and projecting radially into the pocket. The latch is aligned radially with the pocket only in the tool-releasing position. The chuck body engages the latch and forces it into the inner retaining position.

摘要： A drill chuck has a body formed with an axially forwardly open tool-receiving recess and with a plurality of angled guides opening axially forward in the recess. Respective jaws axially and radially displaceable in the guides are each formed with a row of teeth. A tightening ring axially fixed but rotatable about the axis on the body has a screwthread meshing with the teeth so that rotation of the ring displaces the jaws in their guides. An adjustment sleeve is rotatable about the chuck axis on the body. The body has rearward of the tightening ring an outer surface directed toward an inner surface of the adjustment sleeve. Mechanism inside the adjustment sleeve couples the adjustment sleeve to the tightening ring. A support washer has an inner periphery axially fixed to the outer body surface and an outer periphery axially fixed to the inner adjustment-sleeve surface.

摘要： A chuck has a body centered on an axis and formed with a rearwardly open bore adapted to fit with a drive spindle. Respective jaws are displaceable in angled guides of the body and a ring rotatable on the body has an internal screwthread meshing with the jaws for moving the jaws between their end positions on rotation of the ring. A latch element is radially displaceable on the body between a holding position projecting radially into the bore and locking the spindle therein and a freeing position clear of the bore. A sleeve is displaceable between a latched position forcing the element into the holding position and an unlatched position allowing it to move into the freeing position. A spring between the sleeve and the body urges the sleeve into the latched position. The spring is mostly forward of rear ends of the jaws in the rear-end positions thereof.

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.

摘要： A drill chuck has a chuck body formed with a plurality of forwardly open angled guide passages and with a radially open groove having an axially rearwardly directed front face and an axially forwardly directed rear face. Respective jaws displaceable in the passages each have a row of radially outwardly directed teeth exposed at the groove. A tightening ring engaged in the groove and having an internal screwthread meshing with the teeth of the jaws is formed with a front face axially confronting the front groove face and can rotate on the body about the axis. An angled front spring washer engaged between the front faces is elastically deformable on axial forward displacement of the tightening ring to permit limited relative axial movement of the ring and body.

摘要： A chuck has a chuck body rotatable about a main axis and a plate displaceable axially on the body between an outer position and an inner position. Springs urge the plate into the outer position. A locking element on the body can move between a blocking position preventing displacement of the plate from the outer position into the inner position and a freeing position permitting such displacement. A plurality of jaw holders angularly spaced about the axis are fixed axially on the plate and each have radially displaceable outer and inner ends. A piston axially displaceable in the body has cam formations engaging the jaw-holder inner ends for radially displacing the jaw-holder outer ends on axial displacement of the piston.

摘要： A drill chuck has a chuck body centered on an axis and forming an axially forwardly open bit-receiving recess, an axially forwardly open polygonal-section seat at a base of the recess, and a plurality of jaws spaced angularly around the seat. The jaws can be displaced radially inward and outward to grip a bit in the recess. An element can move in the base of the recess between a blocking position in front of the polygonal-section seat and preventing entry of a bit thereinto and a freeing position clear of the seat and permitting entry of a bit thereinto. This element can be actuated for movement between the blocking and freeing positions either manually or automatically.
