杠

In this system the motion controlling centers upon regulating the speed of wire feeding and movement of lead screw in each direction.Four motors separately drive the wire-feeding tape roll and the lead screw move respectively following their directions of X, Y, Z axis. If all the motors are controlled by 89C51 directly,it will rise great difficulty for software and hardware implementation. So the suggested solution is to combine the microcomputer with stepper motor driver and control of their motion.

在本系统中运动控制的关键即送丝与各丝杠移动的调节，由四个电机分别驱动X，Y，Z轴方向的丝杠行走以及送丝操作，运动控制部分如果用89C51直接驱动各电机则在软件和硬件实现上都比较困难的，所以选用单片机与步进电机驱动器结合起来控制它们的运动。

Ordinary lathe knife rest vertical and crosswise enter, give sport to turn from main shaft round sport hang wheel transmit, with cross, enter give gearbox, drive, slip away board case by mere thick stick or guide screw, vertical to slip away the board, slip away board move sideways.

普通车床刀架的纵向和横向进给运动是由主轴回转运动经挂轮传递而来，通过进给变速箱后，由光杠或丝杠带动溜板箱，纵溜板，横溜板移动。

Alistair MacGrath has compared the Christian to a trapeze artist who has let go of one bar and is soaring through the air to catch the other bar swinging toward him. There's a moment when the trapeze artist is suspended in midair—caught in an act of faith.

麦格夫以高秋千杂技演员比喻基督徒，当杂技演员放开一边的杠飞跃空中，伸手准备去抓荡到他身边的另一条杠的那一瞬间，他正悬在半空中，这便是一个单靠信心维系的时刻。

Realizes the robot rotary motion using Step Motor machine actuation and the overtone gear drive, uses another tablecloth Step Motor actuation ball bearing guide screw to revolve, thus causes with the ball bearing guide screw nut vice- solid company at the together arm realization the vertical motion, his/her the arm expansion and contraction movement actuates by the hydraulic cylinder, the entire manipulator through two straight lines directions and a hand of rotation, the realization work piece transporting work, this article has carried on the detailed design to manipulator's mechanism.

利用步进电机驱动和谐波齿轮传动来实现机器人的旋转运动，利用另一台步进电机驱动滚珠丝杠旋转，从而使与滚珠丝杠螺母副固连在一起的手臂实现上下运动，其手臂的伸缩运动由液压缸驱动，整个机械手通过两个直线方向和一个旋转方向，实现工件的搬运工作，本文对机械手的机械结构进行了详细的设计。

Of square-thread form the leadscrew ran through a long "full-nut" of bronze bolted to the underside of the saddle front; because the carriage was permanently connected to the leadscrew the latter carried a dog-clutch at its headstock end and a handwheel, to drive the carriage under manual control, at the other.

方螺纹丝杠跑的形式经过长期&全螺母&青铜螺栓的底面鞍前；因为运输是永久连接到丝杠后者进行狗离合器年底在其启闭和手，驾驶马车手动控制下，在其他。

This is achieved by a split nut.

而丝杠产生的运动是通过溜板箱与丝杠之间的直接机械连接来实现的，对开螺母可以实现这种连接。

An integrated unit of ball screw stripping,ball bearing tapered wedge and fixed-distance pull off was adopted in the design of injection mould for screw plug.

在螺塞注射模具设计中，采用了滚珠丝杠脱模装置和滚珠、斜楔拉模、定距联合装置，利用滚珠、螺母、丝杠及齿轮传动自动拧出螺纹塑件，实现塑件自动脱模；利用滚珠、斜楔、滑块机构拉开定模板和浇口板并控制其拉开距离，从而达到自动生产目的。

For each nut, and screw all gap exists, but in General, there is no gap and screw.

差每个螺母来说与丝杠都有间隙活命，但是从个体来说与丝杠操纵间隙。

This resolves the conflict raised above, guarantees that the screw turning taking ordinary screw joint occurs.

这样不离处置了上背提不入的和解，既可包管丝杠转不静，又可制止别致丝杠呈现的间隙不差错。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
