In order to find out a clue to the solution of torque slip problem in keyless propeller, this study investigates the effects of taper machining error and surface roughness on friction behavior of tapered contact. Pushing-up tests were conducted using model propeller boss (AIBC3) and shaft (SF440A) .<BR>The experiments revealed that the friction behavior especially grip coefficient is significantly affected by taper machining error compared to surface roughness. Accordingly it is proposed that propeller boss should be pushed up into shaft to the regired push-up distance excepting the zone of low grip coefficient.
