CROSS ROLLER BEARING, ANGULAR ROLLER BEARING, AND MANUFACTURING METHOD OF CROSS ROLLER BEARING AND ANGULAR ROLLER BEARING

摘要

PROBLEM TO BE SOLVED: To separately use a cross roller bearing and an angular roller bearing composed of a small number of components according to demanded rigidity and incorporating spaces, etc.;SOLUTION: As the cross roller bearing 14 having a rolling element 25 between an inner ring 14Ir and an outer ring 14Or, a bearing composed of first/second inner/outer rings 21-24 and a roller 25 is used. Both of the inner ring 14Ir and the outer ring 14Or are respectively divided into the first/second inner/outer rings 21-24 along a surface P passing a center 26A of a space 26 surrounded by rolling surfaces 21A-24A of the inner ring 14Ir and the outer ring 14Or and vertical to the axial direction X of a supported body. Thus, a pair of angular roller bearings 16, 18 can be constituted using the inner/outer rings 21-24 and the roller 25.;COPYRIGHT: (C)2010,JPO&INPIT
