摘要： A main shaft drive includes a supply groove that opens to a friction surface, that extends so as to surround a main shaft within a contact range where the friction surface and a pressing surface oppose each other, and that includes an intersecting groove and a discharge opening. The intersecting groove extends in a direction of intersection with a circumference in which a rotational center of the main shaft is a center. The discharge opening is connected to a location that is outside the contact range. By opening a nozzle hole, used for supplying lubricant, towards the supply groove, as the main shaft rotates, four intersecting grooves move relative to the contact range, so that the lubricant is supplied to the four moved intersecting grooves. Therefore, the lubricant easily reaches a location within the contact range where the friction surface and the pressing surface oppose each other.

摘要： In a spindle head for a machine tool in which a spindle (10) to which a tool is mounted is rotated around an axial line of a support shaft (58, 59), two rotating members (9, 58) that form a rotation transmission mechanism for rotating the spindle (10) and that transmit drive force of the rotation driving device (56) are fastened to each other at respective connection sections thereof by a bolt group (301) and are connected to each other so as to be prevented from rotating relative to each other by friction force resulting from the fastening. Rotation prevention torque based on the friction force is a value greater than torque applied to the connection sections during processing and smaller than torque applied to the connection sections when external force that causes the spindle (10) to deform beyond a permissible range is applied to the spindle (10). Therefore, even if the tool or the spindle (10) collides with, for example, a processing tool, the spindle (10) does not become deformed beyond the permissible range.
摘要翻译：在其中安装有工具的主轴（10）围绕支撑轴（58,59）的轴线旋转的机床的主轴头中，形成旋转传递装置的两个旋转构件（9,58）用于使主轴（10）旋转并传递旋转驱动装置（56）的驱动力的机构通过螺栓组（301）在其各自的连接部分处彼此紧固，并且彼此连接以防止通过紧固产生的摩擦力相对于彼此旋转。基于摩擦力的防转矩大于在加工期间施加到连接部的扭矩的值，并且当使主轴（10）变形超过容许范围的外力施加到连接部的扭矩时，施加到连接部的扭矩小于主轴（10）。因此，即使工具或主轴（10）与例如加工工具碰撞，主轴（10）也不会变形超过容许范围。

摘要： In a rotary index device for a machine tool, in which the index position of, for example, a circular table is maintained by normally clamping a clamp disc with a clamping mechanism and in which, for example, the circular table is unclamped by an unclamping mechanism when an indexing operation is performed, the clamping mechanism includes a fixing portion, a resiliently deformable supporting portion, and an urging mechanism. The fixing portion is fixed to a housing of the rotary index device for the machine tool. One end of the supporting portion is secured to the fixing portion, and a pressing portion having a face that opposes the clamp disc is secured to the other end of the supporting member. The urging mechanism normally urges the supporting portion towards the clamp disc to realize a state in which the clamp disc is pressed by the pressing portion.

摘要： A rotational resistance applying device in which a hollow roller is provided between a first surface of a clamp piston (pressing member) and a second surface of a sliding disc (a press member), and in which a pressing force applied to the clamp piston acts upon the sliding disc through the hollow roller that press-contacts the first and second surfaces by displacement of the clamp piston. By this, rolling resistance of the hollow roller resiliently deformed by the pressing force causes a rotational resistance to be applied to a main shaft within a range allowing rotation. This makes it possible to prevent pulsation from being generated in the rotation of the main shaft. In addition, even if the pressing force is applied to the clamp piston, the hollow roller rolls, so that wear of the clamp piston and wear of the sliding disc can be restricted.
摘要翻译：一种旋转阻力施加装置，其中中空辊设置在夹紧活塞（按压构件）的第一表面和滑动盘（压力构件）的第二表面之间，并且施加到夹紧活塞的按压力起作用在通过中空辊的滑动盘上，通过夹紧活塞的位移来压接第一和第二表面。由此，通过按压力弹性变形的中空辊的滚动阻力导致在允许旋转的范围内对主轴施加旋转阻力。这使得可以防止在主轴的旋转中产生脉动。此外，即使对夹紧活塞施加按压力，中空辊滚动，从而可以限制夹紧活塞的磨损和滑动盘的磨损。
