摘要： The inventive drive device for several units of a machine has an inertia drive with an inertia drive spindle (1) driven by a motor, and several inertia drive nuts (2), said nuts being fitted on the inertia drive spindle (1) and being allocated to the units. The inertia drive nuts (2) are each arranged in the housings of the units in such a way that they can turn but cannot be displaced axially. During the rest phase of a particular unit, the inertia drive nut (2) is solidly connected to the inertia drive spindle (1) with a first positive and/or nonpositive fit. For the movement phase of the aggregate, the nut (2) is disconnected from the spindle (1) and is solidly connected to the housing with a second positive and/or nonpositive fit.

摘要： Mecanisme de vissage et d'engagement et de liberation d'un piston de seringue pour une seringue a injection, ou une paire d'ecrous fendus (22, 23) sont mobiles en engagement et hors d'engagement avec une vis mere (15a) a l'aide d'une commande a came rotative (24), la came rotative etant clavetee avec un disque (25) qui est couple a un bras de manivelle (17), jouant le role de moteur du piston de la seringue. Le bras coude est rotatif en engagement et hors d'engagement avec la seringue (11b), cette rotation forcant la paire d'ecrous fendus a se deplacer en engagement et hors d'engagement avec la vis mere. Des moyens d'index et de came (17a, 17b) sont portes par le bras coude pour faciliter l'alignement correct avec le piston de la seringue, et un detecteur (28) est prevu pour controler et s'assurer du bon engagement du bras coude avec le piston.

摘要： An anti-backlash nut (40) is assembled on a reinforced lead screw (2) for bilateral motion lengthwise of the lead screw is rotated. A hollow, elongate reinforcing rail (8) extends lengthwise of and surrounds the lead screw (2). A slot (10) in the rail (8) extends lengthwise of the central axis of the lead screw (2). The anti-backlash nut (40) comprises two separate portions (70, 72), each portion having a tongue (51) which extends radially through the slot (10) and has threads (57) engageable with the threads (4) of the lead screw (2) for moving both nut portions in reciprocating motion lengthwise of the rail (8) when the screw is rotated. Spring means (88) are employed for forcing the nut portions apart to urge the flanges of their threads into forcible engagement with the threads of the lead screw to prevent backlash, while the anti-backlash nut translates laterally along the reinforcing rail.
摘要翻译：一个防止间隙螺母（40）组装在一个加强的导螺杆（2）上，用于双向运动，丝杠长度方向旋转。一个中空细长的加强导轨（8）沿导螺杆（2）的长度方向延伸并围绕导螺杆（2）。轨道（8）中的槽（10）沿导螺杆（2）的中心轴线的长度方向延伸。防止间隙螺母（40）包括两个分开的部分（70,72），每个部分具有舌状物（51），该舌部沿径向延伸穿过狭槽（10）并且具有可与螺纹（4）接合的螺纹（57）导螺杆（2），用于当螺杆旋转时使两个螺母部分沿轨道（8）纵向往复运动。弹簧装置（88）用于迫使螺母部分分开，以推动其螺纹的凸缘与导螺杆的螺纹强制接合以防止齿隙，同时防侧齿螺母沿着加强轨横向平移。

摘要： A flange forming drill means for drilling a hole through the side of a pipe or the like and for forming a hole encircling flange. The drill means comprises: a body (1), a drive shaft (2) rotatably journalled to the body, a drill rod with its drill bit (5) mounted on the end of the drive shaft (2), forming members (6) partly fitted within the drill rod (5), an adjustment member (7), by turning of which around the drill rod the forming members (6) can be made to project beyond the jacket surface of the drill rod (5), supporting legs (8) by which the device can be supported against a work piece (10) and which are fitted on the body (1) on either side of the drive shaft (2) in parallel relationship therewith, a feeding nut (13) mounted on the supporting legs (8) and which can be opened and closed for removal from and engagement with a feeding screw (14) formed on the drive shaft (2). When the drive shaft (2) is rotating and the feeding nut is in the closed position, the supporting legs (8) project outwards from the body (1) resulting in rising of the projecting forming members (6), rotating along with the drill rod (5), from below the edges of the hole and thus forming a flange. The feeding nut (13) is arranged to close automatically by means of a link mechanism (16-20) when the supporting legs (8) have moved a certain distance into the body (1). To the supporting legs (8) are secured brake bits (11) at such a level that they respond to the adjustment member (7) when the supporting legs (8) have moved said certain distance into the body (1). Thereby said brake bits (11) turn the adjustment member (7) relative to the drill rod (5) and effect the extension of the forming members (6) substantially simultaneously with the closure of the feeding nut (13).
摘要翻译：一种用于在管子等的侧面钻孔并形成孔环绕法兰的凸缘形成钻孔装置。钻头装置包括：主体（1），可旋转地安装在主体上的驱动轴（2），具有安装在驱动轴（2）的端部上的钻头（5）的钻杆，形成构件（6）部分地安装在钻杆（5）内，调节构件（7）通过围绕钻杆绕其旋转，使成形构件（6）能够突出超过钻杆（5）的护套表面，支撑腿（8），所述装置可以被支撑在工件（10）上，并且与所述驱动轴（2）的任一侧平行地安装在所述主体（1）上，所述进给螺母（13）安装在所述支撑腿（8）能够被打开和关闭，以便与形成在所述驱动轴（2）上的进给螺杆（14）移除和接合。当驱动轴（2）旋转并且进给螺母处于关闭位置时，支撑腿（8）从主体（1）向外突出，导致突出成形构件（6）的上升，与钻头一起旋转杆（5），从孔的边缘下方形成凸缘。馈送螺母（13）被布置成当支撑腿（8）已经移动一定距离进入主体（1）时通过连杆机构（16-20）自动关闭。在支撑脚（8）已经将所述一定距离移动到主体（1）中时，支撑腿（8）是固定的制动钻头（11），使得它们响应于调节构件（7）。因此，所述制动钻头（11）相对于钻杆（5）转动调节构件（7），并且基本上与进给螺母（13）的关闭同时地实现成形构件（6）的延伸。
