摘要： PROBLEM TO BE SOLVED: To easily measure a cage rotating speed for a roller bearing with the large pin-type cage, with high accuracy at low cost without performing any processing on the cage. SOLUTION: In this method of measuring the cage rotating speed of the roller bearing with the pin-type cage, a gap between a flat part 18a of a cage side plate 18 and a welding projecting part 20 is detected by a displacement sensor 30 having a measurement range of 8 mm or more, its detection signal is converted into the cage rotating speed, and the axial movement of the cage movable in the direction separating from the sensor 30 within the measurement range, and the axial movement of the cage movable in the direction close to the sensor 30 within a range not bringing the cage 17 into contact with the sensor 30 from a standard gap position S are respectively determined to be 2.5-3 mm. An operating speed of the mechanical equipment is decelerated or the mechanical equipment is stopped on the basis of the determined measured value. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To easily measure a vibration acceleration of a cage at low cost when machinery facilities are operated. SOLUTION: Vibration acceleration detectors 40 and 41, and 44 are mounted on the cage 26 and a bearing box 30, respectively. By hitting the shaft 20 when the machinery facilities is stopped, the vibration acceleration of the holder 26 and the vibration acceleration of the bearing box 30 during the standstill period of time are measured, respectively, to obtain the relationship between both the measurement values in advance. Thereafter, the vibration acceleration of the bearing box 30 is measured when the machinery facilities are operated, and the vibration acceleration of the holder 26 during the operating period of time is found from the measured value during the operating period of time and the relationship between both the measured values during the standstill period of time. Further, the driving speed of the machinery facilities is decelerated or stopped, according to the thus obtained vibration acceleration and the permissible vibration acceleration.

Further, scales adhered inside each of the through-holes 18, 18 can be easily removed because diameters of each through-hole 18 can be secured large, and accordingly, the problem can be solved.

摘要： PROBLEM TO BE SOLVED: To provide a roller bearing whose seizure or abnormal wear is prevented under scarce lubrication by reliably feeding lubricating oil therein while increasing the loading capacity of the bearing.
SOLUTION: A separator cage 4 consists of a columnar portion 4a arranged on the side of the raceway surface of an outer ring beyond the PCD of the bearing, a ribbed portion 4b arranged on the side of the end faces of rollers 3, and a protruded portion 4c for constraining the movement of the separator cage while holding the rollers 3. The separator cage 4 has the columnar portion 4a located on the side of the raceway surface of the outer ring beyond the PCD of the bearing. Thus, the number of the rollers 3 can be increased and the loading capacity of the bearing can be increased. The ribbed portion 4b is elastically deformed and the separator cage 4 is inserted between the rollers 3, thus allowing easy incorporation of the separator cage 4. Furthermore, great rounding is applied to an angle portion 4d between the ribbed portion 4b and the columnar portion 4a. This relaxes the stress of the separator cage 4 when inserted.

摘要： PROBLEM TO BE SOLVED: To eliminate problems caused by welding without lowering the load capacity of a rolling bearing.
SOLUTION: Two drill holes 11 are formed in the outer diameter surface of a tapered bush 10, and the same quantity of female screw holes are formed in the inner diameter surface of a second side plate 6. When a bolt 13 is screwed into the outer diameter surface of the tapered bush 10 between the two drill holes 11 and the two female screw holes 12 in the inner diameter surface of the second side plate 6, the bolt is caught by the bottom face of the drill hole 11 formed in the tapered bush 10. When the bolt is further screwed in, the tapered bush 10 is advanced in the direction that a pin 7 is tightened together with the bolt 13. As a result, a fitting force occurs between the pin 7, the tapered bush 10, and the second side plate 6 so that the pin 7 can be fixed to the second side plate by a friction force on the fitted surface thereof.
