VERKTYG FOR DEMONTERING AV LASNING

摘要

A tool for dismantling a locking ring consisting of an annular portion having a plurality of radially projecting circumferentially spaced locking tongues for supporting a bearing element such as a ring in an opening in a housing or the like. The annular portion of the locking ring seats against the axial end face of the bearing element and the tongues wedge against the sidewall of the housing at an angle. The dismantling tool comprises a generally disc-like member having a circumferential rib depending from one axial face thereof adapted to abut the annular portion of the locking ring radially inwardly of the locking tongues. An outer member overlies the disc-like member and has a depending flange closely circumscribing the outer sidewall of the disc member of a diameter slightly smaller than the opening in the housing. The outer member has a plurality of circumferentially spaced teeth with gripping elements adapted to engage through the spaces between tongues of the locking ring and upon rotation confront the back of the tongues and means for axially displacing the gripping member axially relative to the disc whereby the gripping elements of the teeth deform the tongues upwardly to release them from engagement with the sidewall of the opening in the housing.
