    摘要: A linear-motion device has: a linear-motion element fitted on a shaft which moves straight along the shaft; a plurality of balls which are retained in a ball groove formed on the inner side of the linear-motion element and roll over between the ball groove and the shaft; a separator interposed between the balls; and, a circulating path formed in the linear-motion element through which the balls are circulated from one end of the ball groove to the other, which is filled with a grease, wherein the separator is a formed product comprising as a resin component a polybutylene naphthalate-based elastomer formed by a hard segment made of a polybutylene naphthalate and a soft segment made of a polycondensate of 2,6-naphthalanedicarboxylic acid with a polytetramethylene ether glycol.

    摘要: A abnormality diagnosing apparatus used in a machine equipment including a rotating or sliding part relative to a stationary member includes a detecting portion 31 fixed to the rotating or sliding part or the stationary member and including a vibration sensor 32 and a temperature sensor 33, and a signal processing portion 81 for determining a state of the part from a detecting signal outputted by the detecting portion 31. The signal processing portion 81 determines presence or absence of a abnormality, or presence or absence of the abnormality and a degree of a damage of the part based on a combination of a measured result by the vibration sensor 32 and a measured result by the temperature sensor 33.

    摘要: In a case where crowning is provided on a contact surface of a tappet roller by the combination of, for example, two circular arcs, a logarithmic crowning is determined in which an edge load does not occur in the bearing pressure even if its inclination with respect to the cam is {fraction (5/1,000)} or thereabouts, and a crowning profile is set between two logarithmic crownings. In addition, the crowning profile is defined so as to be present between the logarithmic crownings in a case where the axial position x with the center in the direction of a bus set as an origin is at a position 0.85-fold and at a position 1.0-fold the half Le of the effective contact length, respectively.
