摘要： PROBLEM TO BE SOLVED: To provide a micro-traction drive with a long transmission torque, wherein the contact surface of an outer ring, a rotary body and an inner ring is hardly broken, and a lifetime is extended.
SOLUTION: The micro-traction drive comprises a housing 101, an input shaft 102, and an output shaft 103 on the coaxial line with the input shaft 102. In the micro-traction drive, a rotary body 108, revolving around the input shaft 102, is set between the inner ring 104 mounted in the input shaft 102 and the outer ring 106 mounted in the housing 101, and a holder 109 mounted in the output shaft 103 and the rotary body 108 are engaged with each other. A pressure annulus ring 110 is disposed around the axial line of the input shaft 102 or the output shaft 103, and a plurality of inclined faces 111 are formed on the rotary body 108 side of the pressure annulus ring 110. A pressure rotary body 112 is set between the pressure annulus ring 110 and the outer ring 106. When the pressure annulus ring 110 is rotated by the inclined faces 111, the relative pressure force of the inner ring 104 and the outer ring 106 toward the rotary body 108 is adjustable.

摘要： PROBLEM TO BE SOLVED: To establish techniques for detecting the occurrence of damage caused by metal fatigue and the catching of foreign matter, specifying the location of the damage, and determining the development of the damage in a bearing provided for a large-scale rotating machine such as an air preheater. SOLUTION: Two AE sensors S1 and S2 are installed to the bearing 1 at an interval to each other to create a difference signal between their output signals. In the case that a variation exceeding a threshold value present in the difference signal is detected, it is recognized that acoustic waves caused by the damage have occurred in the bearing 1.
