Method for manufacturing split nut

Abstract

A method of manufacturing a split nut comprising the steps of fabricating a first semi-arc shaped member ( 1 ) having thin-walled hinge parts ( 2, 12 ) and thick-walled center parts ( 5, 15 ) at one end and thin-walled engagement parts ( 3, 13 ) at the other end and a second semi-arc shaped member ( 11 ) of the same shape and size as those of the first semi-arc shaped member ( 1 ) and assembling said first and second semi-arcshaped members together enabling the first and second semi-arc shaped members ( 1, 11 ) to be provided by a single metal mold.

1 . A method for manufacturing a split nut comprising the steps of 
 preparing first and second semi-arc shaped parts, each part comprising a thin-walled hinge section, a thick-walled center section and a thin-walled catching section, said first and second semi-arc shaped parts having inner circular surfaces;    coupling said first and second semi-arc shaped parts together such that each catching section faces each other and overlap and the hinge sections of said first and second semi-arc-shaped part face each other and overlap; and    forming threads on the inner circular surface of said first and second semi-arc-shaped parts.    
   
   
       2 . The method of  claim 2  wherein the catching section of said first and second semi-arc shaped parts have substantially identical main subsections that extend outward horizontally, and have substantially identical engaging teeth connected to their main subsections and protrude step-wise with respect to the main subsection, the main subsections and the engaging tooth subsections being slanted in the same direction at the edge surfaces, enabling the catching sections to mate.
