摘要： A pressed cage for a ball bearing is particularly suited for use in severe lubrication conditions. The pressed cage arrangement reduces seizure, holds lubricant for long periods, and thus prolongs the life of the bearing. In the pressed cage arrangement, two annular holding plates include ball holders and flat portions that alternate at regular intervals. The holding plates have a first recess (that may be spherical or semi-elliptic) that has a radius of curvature larger than the ball's radius of curvature. A second, preferably spherical, recess, with a radius of curvature smaller than that of the ball, is formed in the first recess. The ball rotates, being supported only on the boundaries between the first and second recesses, thereby reducing seizure. Spaces formed in the second recess, and spaces between the front portion of the ball and the junction between the holding plates, function as lubricant sumps.

摘要： At least one of constituent elements of a rolling bearing is formed of a metallic material which contains an alloy element having a strong affinity for nitrogen while being of low grade in terms of cost and characteristics, and has a nitriding layer formed on surfaces thereof to be hardened. Accordingly, it is possible to use such rolling bearing as a substitute for conventional rolling bearings or rolling bearings of high grade which are known as general rolling bearings.

摘要： A bearing retainer having a body formed of steel has a nitride layer on the body surface. The average particle diameter of a nitride contained in the nitride layer is not more than 1 .mu.m. The surface of the retainer is subjected to fluoriding treatment, and is then subjected to nitriding treatment. The above-mentioned oxide is removed by replacing an oxide on the surface of the retainer with a metal fluoride film by the fluoriding treatment. In the nitriding treatment, a gaseous mixture of gas for nitriding, for example, ammonia gas and hydrogen gas for removing the metal fluoride film is brought into contact with the surface of the retainer. A precise and uniform nitride layer is obtained in a state where the oxide is reliably removed from the surface of the retainer.

摘要： A screw compressor includes a screw rotor, a gate rotor and an injection mechanism. The screw rotor is provided with multiple helical grooves. The gate rotor is provided with multiple gates meshing with the helical grooves to form at least one compression chamber between at least one of the helical grooves and at least one of the gates. The compression chamber is configured and arranged such that refrigerant taken-in from a starting-end side of the helical groove is compressed and discharged from a dead-end side of the helical groove. The injection mechanism is configured and arranged to inject oil or refrigerant from a discharge hole of the injection mechanism into the compression chamber such that rotational torque is imparted in a direction in which the screw rotor is rotated at a time of compression.

摘要： An inner ring is shaped in its contour by a cold-shaping treatment and is hardened on its surface by a nitrosulphurizing treatment or a soft-nitriding treatment. As a result, the hardness of the surface of the inner ring is enhanced by the cold-shaping treatment and further by the subsequent hardening treatment. As a result, the inner ring is improved in its wear resistance and its seizure resistance. Moreover, the hardening treatment is effected by the nitrosulphurizing treatment or the soft-nitriding treatment so that it can be suppressed from straining in that treating procedure.
