摘要： In a gear train in which a gear case encases a first gear meshing with a second gear having a diameter smaller than that of the first gear, a sufficient amount of lubricant is normally supplied to the upper second gear. As a result, it is possible to provide a lubrication structure of a gear train encased in a gear case designed to prevent occurrence of problems such as poor lubrication and seizure of a gear train. In a lubrication structure inside a gear case having a configuration in which the gear case encases the first gear meshing with the second gear having the diameter smaller than that of the first gear, and the first gear is disposed so as to have a minute gap between the gear case and an outer diameter of the first gear, oil inside an oil chamber below the first gear is pumped up with a movement of gear teeth forming a minute gap by a rotation of the first gear; the pumped oil is discharged into a space above the first gear and inside the gear case; the pumped oil is received by an oil receiver provided in the upper portion of the second gear and including a rib for receiving the pumped oil and a recess surrounded by the rib; and then the oil is supplied to lubricate a gear tooth portion and a bearing portion of the second gear.

摘要： An automatic tool changing device capable of cleaning a contact surface of a spindle, which is to be in contact with a tool holder, with a simple structure. The device includes a turret having a plurality of grippers on its outer circumference and holding the tool holder by means of the grippers. At the time of tool change, the grippers grip and pull out the tool holder fixed to the spindle. Rotation of the spindle causes the turret to rotate through a spindle gear, a turret gear, and a decelerating device, to thereby select a tool. At this moment, a coolant is spouted from a nozzle portion of a manifold toward a spindle taper hole in which the tool holder is interfitted and washes the taper hole. Due to the rotation of the spindle, the coolant is spouted onto the whole circumference of the taper hole, and the surface to be in contact with the tool holder is surely washed. Therefore, it is possible to perform the cleaning with a simple structure in which the nozzle portion is arranged near the spindle without machining the spindle and the tool holder.

摘要： A fixed first sleeve and a movable second sleeve are arranged in a center through hole of a main spindle. Balls at the rear end of the second sleeve engage a recessed slope of the first sleeve and a recessed slope of a draw bar, thereby amplifying the urging force of a spring for urging the draw bar upward. Balls at the distal end of the second sleeve hold and pull in the head of the pull stud with the amplified force. The pull stud has an axial through hole and a hole that connects with the through hole and opens sideways. Compressed air passes through these holes, thereby cleaning the respective taper surfaces and end faces of the main spindle and a tool shank. Switching means is used to close the hole that opens sideways, whereby a cutting fluid is allowed to flow through the axial through hole only.
