摘要:
A steering shaft coupling (1) comprising: an outer tubular shaft member (20), a coaxial inner shaft member (24) slidably inserted within the outer tubular shaft member, and a plurality of wedges (22) located between the outer tubular shaft member (20) and the inner shaft member (24). The plurality of wedges (22) being locking wedges wherein the wedges tend to be retained in the spaces between the shaft members upon application of torque from one shaft member to the other shaft member through the wedges.

A split outer ring (40) has a raceway on a radially inwardly directed surface (54) and a circumferential groove (58) with tapered side walls (44) on a radially outwardly directed surface (46) and comprises a first arcuate portion (50) and a second arcuate portion (52). An alignment ring (48) engages the circumferential groove (58) of the split outer ring, forming an interference fit with the tapered side walls (44) of the circumferential groove such that alignment of the first arcuate portion (50) with respect to the second arcuate portion (52) is maintained. A method of assembling a housed bearing, utilising opposing jaws engaging a similar circumferential groove in the split outer ring, is also disclosed.

An open seam friction rock stabilizer having a compressible body (12) with portions alternately in contact with and not in contact with borehole wall, the contacting portions (30) being separated by an angle (31) between 70 degrees and 150 degrees.
摘要:
A bearing split outer ring (40) for mounting in a bearing housing (12), the split outer ring (40) having a first-portion (44) subtending somewhat more than 180 degrees of arc and a second portion (42) subtending somewhat less than 180 degrees of arc. The first and second portions (44, 42) of the split outer ring (40) being sized with respect to the bearing housing (12) to provide an interference fit therein. In another aspect of the present invention, this is accomplished by providing a method of assembly of a housed bearing. The assembly steps comprise providing a split outer ring (40) with two unequal portions, retaining the split outer ring (40) over an inner raceway with rolling elements (30) therebetween to form a subassembly, positionning the subassembly in a housing base such that the ends of the outer ring are all contained within the housing base, and thereafter, mounting a housing cover over the subassembly.

A door lever assembly having a locked and an unlocked position includes a trim housing (16) and a lever handle (12) and cam (42) rotatably connected to the trim housing. A rotatable shaft (48) extends between the lever handle and the cam, with the shaft defining a connection groove (51) therethrough to provide access to a shaft interior (49). The shaft interior is configured to accept a pin (56) for connecting the cam and the shaft. This pin can be wedgably disconnected following controlled slippage of frictional wedge surfaces in response to excessive force applied to rotate the cam.

An overhead adjustable door holder assembly (10) for attachment between a door jamb (14) and a door (13) to hold the door in an open position includes a jamb bracket (16) attached to the door jamb and a jamb arm (18) pivotally attached to the jamb bracket. A channel assembly (22) having a longitudinally extending channel (23) is attached to the door and a mechanism for holding the door is positioned within the channel assembly, the door holding mechanism having a slide assembly (26) with a slot (30) defined therein for engagement with rollers (42). An adjustment assembly (50) for varying force on the rollers for engagement with the slot of the slide assembly includes a primary wedge (52) connected to a wedge adjust screw (56), with the primary wedge being configured for horizontal movement with respect to a secondary wedge (54) through adjustment of the wedge adjust screw, the horizontal movement acting to vary the force on the rollers.
