Bolt with retaining ring for obtaining a mechanically strong connection of two or more elements sealed by a sealant |
摘要 |
A lockbolt includes a bolt head, a shank, a locking portion, a predetermined breaking point, and a break-away portion. The locking portion includes a knurled surface having knurling peaks between intersecting knurling grooves that extend in a direction with an axial component, e.g. spiraling helically. A sealant on two workpieces smears onto the knurled surface when the bolt is inserted in a hole therein, but does not need to be removed. A locking collar is swaged onto the locking portion to secure the workpieces between the head and the collar. The sealant is distributed as a thin layer to provide a seal and an adhesive bond between the collar and the knurled surface. Excess sealant is squeezed-out axially, without forming encapsulated pressurized sealant pockets and without hindering the swaged engagement of the locking collar onto the knurling. Then the break-away portion is broken-off at the breaking point. |
