摘要:
A laminated nut (10) comprising a plurality of conical spring discs or spring washers (14a-14d) and a cage (16) for receiving and holding the spring discs in a stacked, aligned relationship to define a central opening (22) threaded to be matably received upon an associated threaded bolt, with the cage comprising a plurality of fingers (24) nested within slots (25) defined in the flats of the spring discs and including protrusion means at one axial end of the nut cage to preclude gripping of the nut by a wrenching tool at the one axial end and including a method of manufacturing the laminated nut.
摘要:
A lock nut (10) having a plurality of sides (16) having a crimp radius (18) which is consistent with the radius of the threaded bore (14) in the lock nut (10). Preferably, the lock nut (10) is crimped using a three sided die (52), each die having a crimp radius (118) with relief angles (56). The relief angles (56) are provided at a desired angle to result in the desired amount of contact area between the lock nut (10) and the die (52). The device (40) includes a housing (42), and the housing (42) includes at one end (44) a threaded bore (46) which is configured to mount on a ram. An opposite end (48) of the housing (42) provides a tapered die section (50) in which the three sided die (52) is disposed. The three sided die (52) is engaged with a locking die base (66) which is movable within the housing (42).
摘要:
The invention relates to a threaded fastener. In particular, the invention relates to a threaded fastener such as a nut or a bolt. In an embodiment of the invention, a threaded fastener in the form of a nut (10) is disclosed. The nut comprises a main body portion (12); a lip portion (14) extending from the main body portion; and a recess (16) formed in the main body portion adjacent the lip portion. The recess is shaped to receive at least part of the deformable lip portion when a mating torque is applied to the fastener causing the deformable lip portion to deform. In this fashion, when the fastener is used to clamp two or more components together, such as flanges (20, 22) on adjacent pipe sections, the lip portion encounters a surface of the component that the fastener is being used to clamp against. As the fastener is torqued-up to a desired level, to provide a determined mating force, the lip portion is deformed into the recess in the main body portion.
摘要:
A nut and stud assembly (10) for securing workpieces via threaded engagement of the stud (14) with one of the workpieces and engagement of the nut (12) with another of the workpieces and with the nut preassembled on the stud with the stud having a stop preventing the nut from advancing further on the stud until the stud has reached a preselected position in the one workpiece whereby the nut and stud assembly will function similarly to a headed bolt until the preselected position is attained and thereafter the stop will permit movement of the nut on the stud through such stop and be free running to function similarly to a separate nut and stud combination to a final clamp up of the workpieces.
