摘要： [Summary] The invention provides a rolling bearing assembly adapted to prevent a cage from sustaining burn-out on a guided surface thereof even when a rolling bearing is rotated at high speed, and a method of forming a lubrication device for use in the same. An annular groove 8 for storing a grease G therein is provided in adjoining relation with a guiding surface 7 of an outer ring 2, the guiding surface 7 guiding the rotation of a cage 4. An annular grease reservoir member 30, 40 storing a grease G therein is provided in proximity to the annular groove 8. The grease G stored in the grease reservoir member 30, 40 and the grease G stored in the annular groove 8 are interconnected by means of the grease G present therebetween, so as to supply a base oil contained in the grease G to a space between the guiding surface 7 and a guided surface 6. The grease is packed in an oil groove 33a, 43a of the grease reservoir member 30, 40 and the annular groove 8 of a rolling bearing A. At least one of the greases so packed is formed with a grease protrusion projecting toward the other grease. The grease G stored in the grease reservoir member 30, 40 and the grease G stored in the annular groove 8 are interconnected by means of the grease protrusion.

摘要： The present invention relates to a structure for a rotor of removing bearing oil, including a rotor shaft disposed in a casing of a turbine and an annular oil scattering means formed between an oil deflector and a bearing supporter on the rotor shaft in a circumferential direction to scatter bearing oil flowing from the bearing supporter toward the oil deflector along a surface of the rotor shaft. According to the present invention, it is possible to suppress carbonization caused by reaction with high-temperature operating fluid at the oil deflector by removing the bearing oil flowing between the bearing and the oil deflector along the rotor shaft.

摘要： A rotary seal (10) for a fluid handling machine comprising first circular body (12) with circumferential surface (28) and second circular body (16) with similar surface (27), such that the bodies when coaxially assembled, the circumferential surface (28) and similar surface (27) mate with each other forming a sealing surface contact. An internal end face (33) of rotary seal (10) is exposed to fluids with an inclination, such that the fluid pressure on internal end face (33) adds to contact force at sealing contact surface. The first circular body (12) is continuous and second circular body (16) with a split (17) has a spring characteristic such that two ends formed by the split (17), force away from each other, hence exerting a radial force on circumferential surface when assembled with first circular body (12) and compensating for circumferential wear during operation. The second circular body (16) exerts combination of axial, radial and tangential forces on circumferential surface (28) which results in force closure at sealing surface contact.

摘要： Provide a sliding component that actively takes in fluid on the sealing face and discharges it to circulate the fluid while satisfying the mutually exclusive conditions of sealing and lubricating, thereby preventing deposits from generating on the sealing face and maintaining the sealing function of the sealing face for an extended period of time. The sliding component is characterized in that: with respect to a pair of sliding parts that slide relative to each other, one sealing face has a fluid circulation groove 10 comprising an inlet 10a through which fluid enters from the high-pressure fluid side, an outlet 10b through which fluid is released to the high-pressure fluid side, and a communicating part 10c through which the inlet and outlet communicate with each other; wherein the fluid circulation groove 10 is isolated from the low-pressure fluid side by a land, a positive-pressure generation mechanism 11 is provided in the area surrounded by the fluid circulation groove 10 and high-pressure fluid side, and the positive-pressure generation mechanism 11 communicates with the inlet 10a and is isolated from the outlet and high-pressure fluid side by a land R.
