摘要： A bearing apparatus (1) includes: two split outer ring halves (3a,3b) which are mounted to the housing; a plurality of rolling elements (4) which are provided so as to roll on the two split outer ring halves; and a cage (5a,5b) which holds the rolling elements (4) such that the rolling elements (4) 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： A production method of a coated member (20) is performed in the following way. First, a diamond-like carbon film deposition process in which the diamond-like carbon film (21) is formed on a surface of the base material (4) by generating plasma by applying voltage to the base material (4) in a processing chamber (3) that stores the base material (4), while evacuating the processing chamber (3) and introducing feedstock gas that contains at least a carbon compound into the processing chamber (3). After this, a hydrogenation process in which the deposited diamond-like carbon film (21) is hydrogenated using hydrogen gas by stopping the voltage application and introducing hydrogen gas inducted instead of the feedstock gas, while the evacuation is being continued.

摘要： A drive force transmission device (6) has an outer clutch plate (19) and an inner clutch plate (18), which are rotatable relative to each other about a common rotational axis. The inner (18) and outer (19) clutch plates become frictionally engaged with each other with lubricant oil provided in between. The outer (19) and inner (18) clutch plates each have a sliding surface. The sliding surfaces face each other. A diamond-like carbon film is formed on the sliding surface of the outer clutch plate (19). Fine grooves (42) are formed in the sliding surface of the inner clutch plate (18). The proportion of the sliding area to the sliding surface of the inner clutch plate (18) at the initial stage of use is 55 to 90%.

摘要： There is provided a split rolling bearing 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.
The split rolling bearing according to the invention comprises a split outer ring 2 having 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： A rolling bearing includes an inner ring (10), an outer ring (20), and a plurality of rolling elements (31). A large number of inside dimples (16) in which a liquid lubricant is retained and a large number of outside dimples (18) in which a solid lubricant is retained are formed in at least one of an inner ring raceway surface (12) and an outer ring raceway surface (22). The inside dimples (16) are formed in a contact region (13, 23) at which the raceway surface (12, 22) contacts the rolling elements (31) or in a section of each non-contact region (14, 24), the section being close to the contact region (13, 23). The outside dimples (18) are formed outside a portion in which the inside dimples (16) are formed.
