Moving belts used in power transmissions are an example of a class of mechanical systems commonly referred to as axially moving materials 传动带系统在机械系统中是一个无法替代的传动装置，它可以代替齿轮传动和连杆机构传动等，但反之不然。
With souble oil cylinders , four - column guide and automatically balancing link rod struture to ensure the completely same cutting depth of each cutting position 采用双油缸、四柱导向，自动平衡连杆机构，保证每一个裁断位置的裁断深度完全相同。
With double oil cylinders , four - column guide and automatically balancing link rod structure to ensure the completely same cutting depth of each cutting position 采用双油缸、四柱导向，自动平衡连杆机构，保证每一个裁断位置的裁断深度完全相同。
A kinematic chain portion composed of two linkages and three lower pairs are taken as primary cell and classified into different schemes 摘要给出了机构基元的定义，提出了连杆机构工程语义的描述方法，实现了基于工程语义的机构轨迹曲线方程的算法。
In the process of the design , some mechanisms are obtained according to experiential formulae , so the ultimate results need to be analyzed further 在连杆机构的设计中有一些结构是根据经验公式设计的，所以对最终设计结果，需要进行进一步的分析。
In this paper , to improve the course teaching of mechanism theorem , a visual analysis and simulation program of planar linkage in three dimensional space has built up 机构分析与仿真是机械原理教学的重要内容，其中连杆机构的运动分析是难点与重点。
Linkages are all made of metal in present researches . metal linkages are cheap but heavy . therefore , servomotor needs more power to drive them 在混合驱动连杆机构研究中，原有构件均采用金属材料制成，因为金属材料强度高、价格低廉，易于制造。
As a rigid rotor with special configuration , the crank is always integrated with its accessory components such as shaft and piston when it is under working conditions 曲轴作为结构特殊的刚性转子，在运行中总是与连杆，滑块一起构成一个整体的曲柄连杆机构。
So , with the reciprocal mass of this combinational equipment , the dynamic unbalance of the crank has the special status in the field of the unbalance theory 由于有往复质量的影响，曲柄连杆机构不可能达到完全的平衡，有其特殊性，因此其理论在动平衡领域内占有特殊地位。
Cam - linkage mechanisms can realize many kinds of motions . it ’ s a kind of increasingly developing used widely combined mechanism . therefore , it is necessary to study on it 凸轮连杆机构可实现多种多样的运动,是一种日益发展、用途广泛的组合机构,很有必要对其进行研究。
