    Abstract: The chuck includes a body with an axial recess and a transverse opening intersecting the recess. First and second cam members are disposed at least partially within the transverse opening and have first and second passages, respectively, which squeeze a cylindrical, slitted inner sleeve that holds the tool shank during rotation of the chuck. The inner sleeve is spring-biased for axial movement relative to the body and has a tapered upper end that is compressed when engaging a tapered retainer sleeve and thereby retains the tool shank during nonrotation of the chuck. An outer sleeve including comolded inner and outer shells, is configured and disposed to move axially about the body. A remote actuating member effects axial movement of the outer sleeve and inner sleeves to permit insertion or withdrawal of the tool shank from the chuck. An engagement mechanism connects the chuck to a drive spindle and also has a mounting mechanism for facilitating automated mounting of the chuck to a drive spindle.

    Abstract: A collet chuck (1) having a chuck body (3), a collet (11) disposed in the body (3), a nose ring (23) for radially compressing the collet (11), and a locknut (30) for axially moving the nose ring (23) into compressive engagement with the collet (11) is provided with a bearing assembly (45) disposed between the nose ring (23) and the collet (11) which loads compressive forces in a direction which is advantageously parallel to the axis of rotation (A) of the chuck. Both the locknut (30) and the nose ring (23) include flange portions (27, 43) that confront each other with opposing surfaces (47, 49) that are complementary in shape to the spherical profile of the ball bearings (50) and which traverse a line (L) parallel to the axis of rotation (A) of the chuck. The collet chuck (1) further includes O-rings (61, 65) disposed between the nose ring (23) and the locknut (30) both in front of and behind the ball bearings (50) for sealing the bearing assembly (45) against dust and debris and retaining lubricant. Finally, the portion of the nose ring (23) which wedgingly engages the collet (11) to compress it inwardly is undercut with a groove (72) in order to enhance the compliance between the nose ring (23) and the collet (11), thus providing a more uniform radial compressive force around the collet (11) which in turn results in improved gripping characteristics.

    Abstract: Hydraulic bushings (1) are generally provided with a peripheral flange in which a pressurizing means (3, 4, 5) is arranged. A desire has been expressed to eliminate the peripheral flange. According to the present invention this is made possible by placing the pressurizing means (3, 4, 5) in the rear end (6) of the bushing (1).

    Abstract: This invention relates to a chuck assembly (12) for a drill box (10) of a mine drill for releasably securing a mining tool (14) including a working end (16) and a depending rod-like member (18) for roof bolting and roof and face drilling operations and a method of using the chuck assembly. The drill box (10) includes a source of rotary power (20) and a drive member (22) operatively connected to the source of rotary power (20) to rotatably drive the chuck assembly (12). The chuck assembly (12) includes a spindle (28), a collet closer (32) and a collet (30). The spindle (28) is operatively connected to the drive member and has a sleeve (34) of a cylindrical shape including a threaded collar end (40) and a bottom end (37) and an opening (35) extending a selected distance from the collar end (40) to the bottom end (37). The collet closer (32) includes an annular housing (54) having an aperture (62) threaded for threadingly engaging the threaded collar end (40) of the spindle. The collet (30) includes a forward end portion (48) and an opposing tapered rear end portion (50) and an internal bore (56) capable of receiving the rod-like member (18) of the mining tool. The collet (30) extends a selected distance within the opening of the sleeve (34) such that the collet (30) closes uniformly around the rod-like member (18) of the mining tool (14) as the collet (30) is compressed within the opening of the sleeve (34) by the action of the collet closer (32) threadingly engaging the threaded collar end (40).
