Title:
AUTOMATIC LOCKING TYPE JOINING NUT
Document Type and Number:
Japanese Patent JPS57154509
Kind Code:
A
Abstract:
A self-locking coupling nut (14) includes a nut surrounding a first shell (12) for threaded engagement with a second shell (66) to secure the shells in mating engagement. A plurality of balls (52) mounted in the nut are initially engaged with a ball receiving surface (24) on the first shell, and upon threaded engagement between the nut and second shell are cammed outwardly into ball receiving grooves (32) to secure the nut against inadvertent disengagement from the second shell. Outward movement of the balls cams a spring (56) outwardly to provide visual and tactile proof of the locked condition of the self-locking coupling nut. Threaded engagement of the nut with the second shell also compresses a spring between a thrust ring (20) on the first shell and a retaining ring (44) on the nut.
