The relative velocity of the two surfaces can be determined in coordinate system K2F using the transformation between K1F (x1F, y1F, z1F) coordinate system for worm and the K2F (x2F, y2F, z2F) coordinate system for worm gear: ( ) FFFFF rM dt dr dt dv 11,22 )12( 2 rrr ⋅=⋅= (18)	cache/hjic-405.pdf	txt/hjic-405.txt
