Through the intermediate gear Z12, the elevator shaft's gear Z13 and shaft are driven to turn, then via friction cone clutch or planetary mechanism the drum obtains six hoisting speeds.

a、冲击钻进：将变速箱右手柄板至&卷扬&位置，变速箱Ⅲ轴齿轮Z8与Ⅳ轴的齿轮Z10啮合，经中间齿轮Z12带动升降机轴上齿轮Z13及轴旋转，通过锥形摩擦离合器或游星轮机构使卷筒获得六种提升进度

The declination axis is set on the two ends of the inner frame in east-west direction.Using a hand-operated screw adjusting mechanism,the angle between the receive plane and the right ascension axis is controlled to be equivalent to the latitude every day.Tracking time is limited from 7 am to 5 pm,the concentrating area is 10 m~2,and the driver power is only 12 W.

自行设计了双轴调节太阳跟踪装置，其特征在于通过南北向布置的赤经轴按时钟角速度转动，同步带动一个挂在赤经轴两端的内框转动，在内框的东西框边的赤纬轴上安装有接收面支架，由手动螺旋调节机构调节接收面支架的平面与赤经转轴的夹角每天等于赤纬度。

In this thesis, agitating shaft is defined as an assembly including shaft and accessories , such as agitators, shaft couplings.

本论文中所指的搅拌轴包括轴本身和随轴转动的附件，如搅拌器、联轴器等。

The introductive robot arm of this text can output two lines pulses by the PLC, driving the horizontal stalk, and the perpendicular stalk to drive the electrical engineering actuator respectively, to control the robot arm precision of the horizontal stalk and perpendicular stalk at the fixed position, tiny move switch input the position signal to the PLC.The direct current motor drags along to begin the claw and bedrocks to revolve, the position signal from revolve the code dish and near to the switch feedback to host of PLC;The electromagnetism valve control the machine hand open and close, thus carry out the function of the machine hand precision work.

本文介绍的机械手是由PLC输出两路脉冲，分别驱动横轴、竖轴步进电机驱动器，控制机械手横轴和竖轴的精确定位，微动开关将位置信号传给PLC主机；直流电机拖动手爪和底盘旋转，位置信号由旋转码盘和接近开关反馈给PLC主机；电磁阀控制气开阀的开关来控制机械手手爪的张合，从而实现机械手精确运动的功能。

The formulae of the anterior surface are ellipsoids, with the major axis on the Z axis and the short axis on the Y axis.

正视儿童角膜前表面为长轴在Z轴、短轴在Y轴的长椭球面。

Related keyway, and bolt coupling mainly refers to camshaft keyway, keyway and flexible coupling flange connection piece (with the pump power transmission coupling), Half key, as well as fixed coupling bolts.

相关键槽、联轴节及螺栓主要是指凸轮轴键槽、联轴节凸缘键槽和弹性连接片（用联轴节传递动力的油泵）、半圆键以及联轴节固定螺栓。

All the actuators of the three-axis turntable are brushless torque motors, all the bearings are aerostatic air bearings, so the friction caused by these elements can be neglected. The main source of friction is the metal-to-metal friction on the slip rings. Hence the "Columb+Viscous+Static" friction model is used here for analysis.

由于三轴转台的驱动系统选用的是无刷电机，轴承则采用的是气浮轴承，轴系上的摩擦力已大大降低，三轴转台上的摩擦主要是滑环轴上金属对金属的摩擦，所以文中选用&库仑＋粘滞＋静摩擦&的摩擦模型来进行分析。
