System for securing two tubular components one in the other, carrying a roller bearing

摘要

A system for securing first and second tubular coaxial components carrying a roller bearing is provided. The system includes a forcing nut mounted inside the coaxial components and axially abutting against the first component after screwing-in of the second component; and a locking pin for preventing unscrewing of the nut and being arranged between the nut and the first component. The system also includes a cylindrical sleeve being arranged between the pin and the first component, being secured axially relative to the first component, and including an axial stop against which the pin is applied; and first and second devices for linking the pin and the first component in rotation, respectively, with the sleeve.

1. A system for securing an end of a first tubular component to an inside of a coaxial second tubular component carrying a roller bearing in order to hold the roller bearing in position, said system comprising:
a forcing nut mounted inside the first and second coaxial tubular components, a first end of the forcing nut including external threads which are screwed onto internal threads of the second component and a second end of the forcing nut including an external edge which axially abuts against an internal shoulder of the first component when the forcing nut is screwed onto the second component; a locking pin for preventing unscrewing of the forcing nut, the locking pin being arranged between the forcing nut and the first component; and a cylindrical sleeve arranged between the locking pin and the first component, the sleeve being secured axially relative to the first component, and including an axial stop against which the locking pin is applied, wherein first rotational linkage means are arranged between the locking pin and the cylindrical sleeve, and wherein second rotational linkage means are arranged between the first component and the cylindrical sleeve.
