Abstract
Det er beskrevet en forbedret, styrbar bore- hullsmotormontasje (5) og en beslektet fremgangs- måte. Et problem ved kjente montasjer er at avstanden fra et bøyd hus sin bøyningsakse til frontsiden av en borkrone trenger å holdes forholdsvis kort, noe som resulterer i at lengden av lagerpakken og dens aksial- rrykkskapasitet er begrenset. Oppfinnelsen tilveie- bringer følgelig en borehullsmotormontasje (5) som omfatter en motor (115), minst ett trykklager (l 16) og en bøyd del (117), idet montasjen (5) har en første ende (135) og en andre ende (140), idet den første ende (135) ligger nærmere overflaten enn den andre ende (140) ved bruk, hvor den bøyde del (117) ligger nærmere den andre ende (140) enn det minst ene trykklager (l 16).
