  • Patent number: 9021460
    Abstract: A software management system provides a software management device which manages a plurality of software programs installed in a plurality of managed devices in connection with a plurality of software-updating module delivery devices. The software management device receives adaptive version data from the managed device and current version data from the software-updating module delivery device. When the current version of software, indicated by current version data, is later than the adaptive version of software, indicated by adaptive version data, the software management device downloads software-updating modules from the software-updating module delivery device, thus updating the adaptive version of software installed in the managed device by use of software-updating modules.

  • Patent number: 7309197
    Abstract: An internal gear shaving machine 1 which brings a shaving cutter 3 and an internal gear held by a workpiece chuck 2 into engagement with a crossed axes angle, and subjects the tooth flanks of the internal gear to final machining while it rotationally drives at least one of the shaving cutter 3 and the workpiece chuck 2. The workpiece chuck 2 and shaving cutter 3 are supported movably toward and away from each other in a vertical direction with the workpiece chuck 2 higher and supported movably in the horizontal direction relative to each other. The workpiece chuck 3 is constituted to hold the outer circumferential surface of the internal gear with the axis of rotation of the internal gear oriented in a up-down direction so that shavings produced during processing by the shaving cutter can fall downwardly from the internal gear.

  • Patent number: 5882154
    Abstract: A gear finishing apparatus with helix compensation is disclosed, in which a helical gear is supported and rotated on a table by a gear holder and a tail stock, a finishing wheel is supported and rotated on a slider that can move toward and away from the finishing wheel in a substantially perpendicular direction to the gear axis, and the table and the slider are structured to relatively reciprocally move in the gear axis, wherein the gear holder comprises a drive motor for rotating a holder shaft for holding the helical gear; and a compensation drive unit by which a motor drum holding the drive motor is rotated about the gear axis, thereby compensating the circumferential speed in accordance with the helix angle of the helical gear during the relative movement of the helical gear and the finishing wheel in an axial direction of the gear and realizing high accuracy in the tooth profile of a helical gear.

  • Patent number: 5615982
    Abstract: A gear finishing apparatus having a construction in which a support gear supported by a finishing wheel holding section can support and fix a plurality of finishing wheels in parallel, wherein a finishing wheel holding section makes it possible to move an operating portion for holding and rotating the finishing wheel in a direction parallel to the axis of the finishing wheel and to fix it at predetermined positions within the extent of the movement. If the plurality of finishing wheels are attached to the support gear and the positions thereof are adjusted in advance, a new finishing wheel in an adjusted position can be brought into a processing position by moving and fixing the operating portion of the finishing wheel holding section when one of the attached finishing wheels is worn out, thereby obtaining a rapid and continuous finish processing. Further, if different kinds of finishing wheels are attached in advance, the time required for finishing different kinds of gears to be processed can be reduced.

  • Patent number: 4971488
    Abstract: A first table (1) slidable leftwards and rightwards of a gear finishing machine and a second table (2) slidable forwards and rearwards of the machine are disposed in an overlapped relationship such that one of the tables is mounted on the top of the other table. Of these tables, the upper table is guided by a horizontal guide member (3) which is adapted to be rotated to any desired angular position and to be clamped at such position. A feed motor (5) drives the first table to slide.For sliding the table assembly along a diagonal direction, the angular position of the guide member is adjusted so that it extends along such direction.A horizontal stability of the table assembly is secured without employing a conventional parallel link mechanism. The table assembly is driven to slide so as to pass the center of machine so that an accuracy of gear finishing is assured.
