It is intended to provide jigs enabling a worker to hold a lock ring while resisting the elastic repulsion force urging contraction of the lock ring, inward in the radial direction, without the need for propping up a heavy lock ring. There is provided a lock ring mounting/demounting jig, the jig including two jigs in pairs, the jigs (41, 42) in pairs, constituting the jig, being joined with each other by a screw bolt (8), in which the jigs in pairs are mountable on respective ends (4a, 4b) of a lock ring (4), the jigs (41, 42) each include a main block (41B, 42B) and a clamp (41C, 42C), and the jigs (41, 42, 410, 420, 411, 421) in pairs are structured such that an interval therebetween is stretchable.
L'invention concerne la fourniture d'un gabarit, qui ne nécessite pas que l'ouvrier maintienne un anneau de verrouillage à l'encontre de la force élastique de rétreint radial et de supporter le poids de l'anneau de verrouillage. Le gabarit de montage/démontage d'anneau de verrouillage est constitué d'un ensemble de deux gabarits (41 et 42), qui sont reliés par un seul boulon fileté (8) et peut être monté individuellement sur les deux parties d'extrémité (4a et 4b) d'un anneau de verrouillage (4). Les gabarits appariés (41 et 42) sont constitués pour comprendre des parties de corps (ou blocs (41B et 42B)) et des parties de pince (41C et 42C) de sorte que le jeu entre les gabarits assemblés (41, 42, 410, 420, 411 et 421) peut s'agrandir et se contracter.
