摘要： A bearing apparatus includes: two split outer ring halves which are mounted to the housing; a plurality of rolling elements which are provided so as to roll on the two split outer ring halves; and a cage which holds the rolling elements such that the rolling elements are disposed at substantially equal intervals in a circumferential direction of the cage and which is split at a position of the cage to form joint surfaces, an outside diameter of the cage being guided by inner circumferential surfaces of the split outer ring halves. An outside diametrical dimension in a normal direction to the joint surfaces is made larger than an outside diametrical dimension of the cage in a direction parallel to the joint surface, and vicinity of an outside diametrical position of the cage lying in the normal direction is made to be guided by the outer ring halves.

摘要： There are provided a split outer ring which can suppress the reduction in durability and which can suppress largely the generation of noise or vibration which is caused in association with the passage of rolling elements over a mating surface and a split rolling bearing which employs the same outer ring.A split outer ring 2 according to the invention has first and second split outer ring members 5, 6 which are formed into a cylindrical shape by being butted against each other at circumferential end portions. First flat plane portions 7 and a V-shaped recess portion 8 which is recessed in a circumferential direction are formed at one end portion 5a of the circumferential end portions which are butted against each other. Secondary flat plane portions 9 which are to be brought into abutment with the first flat plane portions 7 and a projecting portion 10 which projects in the circumferential direction from the second flat plane portion 9 so as to be introduced into the recess portion 8 are formed at an end portion 6a which is to be butted against the end portion 5a. A space S is formed between the recess portion 8 and the projecting portion 10 so as to avoid a contact between a bottom portion 8b of the recess portion 8 and a vertex portion 10b of the projecting portion 10.

摘要： There is provided a rolling bearing including an inner ring having an inner ring raceway surface, an outer ring having an outer ring raceway surface and a shoulder portion formed on one axial side of the outer ring raceway surface, a plurality of rolling elements which roll between the inner ring raceway surface and the outer ring raceway surface, and a cage adapted to hold the plurality of rolling elements at predetermined intervals in a circumferential direction and having a guided surface which confronts the shoulder portion of the outer ring in such a manner as to be brought into sliding contact therewith. The rotation of the cage is guided through sliding contact of the guided surface of the cage with a guiding surface of the shoulder portion of the outer ring. A guiding space which is a radial space between the guiding surface of the shoulder portion of the outer ring and the guided surface of the cage is made to increase as approaching the rolling elements.
