Abstract
Nut with positive and micrometric locking intended to be screwed on a shaft (1)(23)(60)(70) comprising a serrated part (2)(24)(59)(72) and locking segments (15)(37)(44)(75) having each one at least one tooth (19)(41)(58)(76), and which are intended to fix in rotation the nut (4)(26)(54)(73) on the shaft (1)(23)(60)(70), said locking segments (15)(37)(44)(75) being movable between a first locked position and a second unlocked position, the locking segments (15)(37)(44)(75) being constantly and independently radially stressed by a torical spring (21)(43)(45)(78).
Claims15
A positive and micrometric locking assembly comprising:
- a threaded shaft,
- a nut threadably engaged on said shaft,
- plural locking segments movable between a locked position and an unlocked position, each said locking segment including an aperture and at least one tooth,
- wherein one of said shaft or nut comprises axial grooves and the other of said shaft or nut has said at least one locking segment pivotally connected thereto, and said locked position comprises the engagement of said at least one tooth with at least one said axial groove, rotationally locking said nut relative to said shaft,
- a resilient ring received in said aperture for urging said locking segments radially toward said locked position,
- whereby each said locking segment is constantly and independently urged toward said locked position by said resilient ring allowing each said locking segment to move independently of other segments and at least one said locking segment achieves said locked position.
A positive and micrometric locking assembly comprising:
- a threaded shaft including an end having axial grooves,
- a nut threadably engaged on said shaft, said nut including an external circular groove located in an external surface of said nut,
- plural locking segments carried by said nut and movable between a locked position and an unlocked position, each said locking segment including a externally oriented aperture and at least one tooth, said locked position comprising the engagement of said at least one tooth with at least one said axial groove, rotationally locking said nut relative to said shaft, and
- a resilient ring received in said external circular groove and said externally oriented aperture for the purpose of urging said locking segments radially inwardly toward said locked position,
- whereby each said locking segment is constantly and independently urged toward said locked position by said resilient ring and at least one said locking segment achieves said locked position.
