The welding process of the butt welding machine used to weld bicycle joints employs a cam transmission mechanism. Its procedure is decided by the contour of the cam.

自行车接头对焊机焊接过程的进行采用凸轮机构控制，焊接过程由凸轮的外廓形状所决定。

This paper determines the motion of lower rocker arm in valve gear by the dimension of cam mechanism and derives the characteristics of equivalent cam,assuming that the rocker arm ratio varies according to the camshaft angular displacement while the push rod and both the upper and lower rocker arms are in motion.

本文根据凸轮机构的几何尺寸确定配气机构下摇臂的运动，并且考虑上下摇臂及推杆的运动，将摇臂比看作是随凸轮转角变化的变量，从而导出当量凸轮的运动规律。

Axotomized, turn the paper of the cam disconnect switch on the side of the circuit, forcing 3XK press paper cutter and a loss of power, but the operators have not yet had enough time to release the button, turn the paper cutting of the cam over the limit switch 3XK, 4J and 1 c was electric pick-up, gnashing paper cutter does not reset, in this case, a rotating cam on the other side lost your limit switch XM, intermediate relay 5J load-disconnected.

纸张切断后，转动的凸轮一侧断开行程开关3XK的回路，迫使压纸和切纸断电，但是操作者还未来得及松开切纸按钮，转动的凸轮滑过行程开关3XK后，4J和1C仍得电吸合，造成切纸刀不复位，这时，转动的凸轮另一侧断开了行程开关XK，中间继电器5J失电断开。

Relying on the several years experience and technology power of CNC four axis, the factory has become the specialized one manufacturing rotary products like cylinder cam, type cam, abnormal cam, rolling cutter, circle cutter, propeller, impeller, screw groove, adjustable screw groove, closed curve groove etc.

Then a solution of CAD/CAM of the camis put forward. The following work has been completed. Based on analysis of transmission, structure and profile formation principle of thecam, the basic kinematic formula of the gear indexing cam mechanism isdeduced. Furthermore the space meshing contact equation of cam profile and theroller is formulated.

在此基础上提出了弧面分度凸轮的CAD/CAM解决方案，论文得到如下主要结论：在对弧面分度凸轮传动形式、结构和廓面成形理论分析的基础上，推导出了弧面分度凸轮机构的基本的运动学公式，凸轮廓面与滚子的空间共轭接触方程。

The truth of the measuring method is established by precision and feasibility analysis.The restriction of using this method to measure surfaces of roller gear cam is discussed, and the next research direction is confirmed.

分析了这种弧面分度凸轮测量方法的局限性，即该方法只适于对已知参数的弧面分度凸轮进行精度检验；如果要测量参数未知的凸轮，反求参数，这种方法是不适用的；针对该方法的局限性确定了下一步的研究方向。

Using cam for 492Q engine and coupled spherical tappets (R750mm, R2000mm) an investigation in the influence o tappet rotation on anti-scuffing property of camtappet is carried out on TM-1 cam-tappet wearing tester at speed of camshaft 1500r/min and 1050r/min.

本文对498Q发动机凸轮和与之配对的球面挺柱(R750mm、R2000mm)分别在凸轮轴转速为1500r/min和1050r/min两种工况下，在TM—1型凸轮挺柱磨损试验机上，进行了挺柱转动对凸轮挺柱摩擦副抗擦伤性能影响的试验。

Although the valve lift of PA6B is bigger than PA6s, the cam lift becomes small with a bigger ratio of the rocking arm, this is of advantage to enhance the working life of cam.

这样尽管气门升程较PA6柴油机大，但由于其增大了摇臂比，所以凸轮升程反而较小，有利于凸轮设计及提高凸轮寿命。

The valve is mainly made up of body, disc, axle, rocker, connecting rod, cam and spring etc, realizing discharging and air locking making use of the continual action of cam, connecting rod and spring. The cam is controlled by electric pneumatic, so the open angle and time of valve can be controlled in some range by reducing gear.

电动锁气翻板卸灰阀主要由阀体、阀板、阀轴、摇杆、连杆、凸轮、弹簧等零件组成，利用凸轮、连杆、弹簧连续动作实现锁气卸灰，凸轮系统由电气控制，因而阀板的开启角度和时间可由减速装置控制在一定范围内。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
