    摘要： A valve opening and closing timing control apparatus which restrains generation of hitting sound in a case where a driven-side rotation member and a driving-side rotation member rotate relative to each other by an electric actuator includes a phase adjustment mechanism of a gear type specifying a relative rotation phase between the driving-side rotation member which rotates synchronously with a crankshaft and the driven-side rotation member which rotates integrally with at least one of an intake camshaft and an exhaust camshaft by a driving force of the electric actuator, the phase adjustment mechanism causing a revolution of a position of an eccentric axis about a rotation axis by the driving force of the electric actuator so that an input gear connected to the driven-side rotation member via an Oldham coupling rotates relative to an output gear fixed to the driven-side rotation member, a groove portion in a linear form and a protruding portion in a rectangular form in the Oldham coupling slidably engaging with each other between the driving-side rotation member and an Oldham ring, a groove portion in a linear form and a protruding portion in a rectangular form in the Oldham coupling slidably engaging with each other between the Oldham ring and the input gear.

    摘要： Provided are a method of grinding a cutter for skive-machining a work and a device for grinding the skive-machining cutter which method and device allow formation of a better gear with a cutting operation. The target of grinding is a skive-machining cutter in which a plurality of helical groove portions are formed. A first grinding step is effected for grinding one of a pair of blade lateral faces facing the groove portion. A second grinding step is effected for grinding the other of the pair of blade lateral faces. Then, a third grinding step is effected for forming a blade tip face to be continuous with the blade lateral face formed in the first grinding step and the blade lateral face formed in the second grinding step.

    摘要： Provided is a method for manufacturing a base material for a wave gear which enables the effective suppression of man-hours and manufacturing cost while providing the required strength and elastic deformation characteristics for an external gear of a wave gear. In this manufacturing method, steel having a carbon content of 0.48% or less is subjected to primary molding by being cold worked into the shape of an external gear for a wave gear. The resulting primary molded article is heated to a temperature range (T 1 ) in which the main phase of the metallographic structure thereof forms an austenitic structure. The main phase of the metallographic structure is formed into bainite by carrying out quenching to a predetermined temperature (T 3 ) higher than the martensitic transformation starting temperature and maintaining the temperature for a predetermined time. The product is then cooled to normal temperature.
