Abstract:
1. An incremented force bearing comprising a bearing substrate formed of multiple rings comprising an outer ring, an inner ring, and at least one intermediate ring interposed between said outer ring and inner ring, said outer ring, inner ring and at least one intermediate ring being coaxially rotated, rotators interposed between respective outer, inner and intermediate rings so as to be mutually rotated while being coaxially rotated, horizontally swingable levers serving as an incremented force medium for transmitting a rotative force from said outer ring to said inner ring interposed between said outer and inner rings and arranged in equal intervals in the circumferential direction, and an annular recess provided on and recessed in the upper surface of said bearing substrate, said levers being arranged on said annular recess about a rotating center of the outer and inner rings, said outer and inner rings having annular wavy slide surfaces formed of repeated concavities and convexities, wherein said annular wavy slide surface of said outer ring has a pitch L of the concavities and convexities greater than a pitch M of the concavities and convexities of said annular wavy slide surface of said inner ring such that when said levers are positioned between said annular wavy slide surfaces, a driving force due to the engagement of said concavities and convexities of said annular wavy slide surface of said outer ring and said levers can be transmitted as an incremented force to said inner ring due to the engagement between said concavities and convexities of said annular wavy slide surface of said inner ring and said levers.
