摘要： A valve opening and closing timing control apparatus includes a phase adjustment mechanism of a gear type specifying a relative rotation phase between a driving-side rotation member and a driven-side rotation member by an electric actuator, the phase adjustment mechanism causing a revolution of a position of an eccentric axis about a rotation axis by 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： A combined gear cutting apparatus includes a workpiece drive portion, a first processing portion holding and moving a first tool to a processing position for a workpiece, a second processing portion holding and moving a second tool to a processing position for the workpiece, and a control portion which includes a storage portion storing workpiece information indicating a configuration of the workpiece before first processing is performed, first tool information, second tool information and relative position information. The control portion includes a tooth groove configuration calculation portion calculating tooth groove configuration information of the workpiece based on the first tool information, the workpiece information and the relative position information obtained when the first processing is completed. The second tool is configured to move to a start position of second processing for the workpiece based on the tooth groove configuration information, the second tool information and the relative position information.

摘要： A damper includes: first and second rotating elements rotatable around a rotation center; an elastic element elastically expanding and contracting in response to relative rotation of the first and second rotating elements; and a limiter provided in the first rotating element. The limiter includes a lining plate having a first sliding surface, a first cover plate having a second sliding surface and a first abutting surface, a second cover plate having an outer edge part and an inner edge part, and a biasing member. When a difference in torque between the lining plate and the first cover plate is a predetermined value or more, the first sliding surface slides with the second sliding surface, and the second sliding surface is inclined with respect to the first abutting surface so as to face the second direction as going radially inward in a free state of the first cover plate.

摘要： A gear manufacturing device includes a control unit for synchronously rotating a work rotating about a work axis and a cutter rotating about a cutter axis, the work axis and the cutter axis being skew to each other, the control unit relatively moving the cutter and the work in an axial direction of the work with a predetermined cutting depth, and a correction control portion executing at least one of a position correction and a phase correction when an amplitude value of a vibration detected by a vibration sensor during a machining reaches equal to or greater than a set value, the position correction for correcting a relative positional relationship in a direction to correct the cutting depth, the phase correction for correcting a relative phase in a direction to correct an unbalance cutting that is otherwise to be applied on a pair of tooth surfaces formed on the work.

摘要： A method for processing a gear includes a first cutting process starting the cutting of a work by moving a cutter in a first cutting direction while maintaining a cutting depth of the work at a setting value and reducing the cutting depth of the work before a first cutter portion reaches an end portion of a cutting area in the first cutting direction and a second cutting process synchronously rotating the work and the cutter in a reverse direction of rotational directions of the work and the cutter in the first cutting process, maintaining the cutting depth of the work at the setting value, and cutting the end portion of the cutting area by moving the cutter in a second cutting direction.
