In contrast with other types of door mechanism , it is smooth and reliable in movement . the - driving gear is installed under the step plate , thus occupying no room inside the bus 它与其它内摆乘客门门机相比，具有密封性能好，运行平稳、可靠，驱动装置安装在踏步板下、不占车内空间等优点。
This machine employs vibration motor driving gears , which ensures stable operation , sturdy and reliable work , steady performance and low vibration and noise . there ' s no powder and it is easy to operate and to provide maintenance to it 本机采用振动电机传动机构，运转平稳，牢固可靠，工艺性能稳定，振动小噪声小，无粉尘外溢，及操作维修方便。
The key factor influencing the automobile ' s drive bridge performance is the reducer assembly quality , and the tightening at the bearing of the front - part of the driving gear axis is an important problem in the process of the reducer assembly 汽车驱动桥主减速器的装配质量是影响驱动桥整体性能的一个关键因素，主减速器装配过程中的一个重要问题就是主动锥齿轮前端的一对圆锥滚子轴承的预紧。
The build - up welding of the meshing surfaces of big gear wheels : during operations of the big driving gears of big rolling mills and squeezers , the meshing surfaces wear easily and form cavities due to the squeezing force and attrition with the thinning of the gears resulting in the rejection of the gear wheels 大齿轮咬合面堆焊：大型轧机和压榨机的传动大齿轮在工作过程中，齿的咬合面产生大的挤压力和磨擦力易磨损和形成凹坑，齿厚减薄，因而报废。
It starts with the structure and functions of the final drive , which helps in testifying the importance of noise or vibration analyzing . then the sources and principles of the noise of final drive gear are presented . and the close relationship between noise and vibration signal is discussed 论文从主减速器的功能和结构入手,说明了对其噪声振动信号进行分析的必要性,阐述了主减速器齿轮噪声产生机理和来源,并分析了噪声信号与振动信号之间的密切关系。
Based on the fact of driven gear moving prior to normal locality when driving gear pair moving from upper dead center to lower dead center , considering all influential elements , the maximum backlash of gear pair can be controlled to satisfy the special driving requirement through controlling the length and deviation of its common normal without increasing its manufacture precision 摘要根据换向传动齿轮副从上止点向下止点运动时被动齿轮运动超前的实际，从影响齿轮副侧隙的各种因素出发，在不提高齿轮副制造精度的前提下，通过拉制齿轮副公法线长度及其偏差从而有效地控制齿轮副的最大齿侧间隙，以满足传动的特殊要求。
So the evaluation index of the bsc embodies both financial indicator and non - financial factors such as customer satisfaction , inner operational process and study and growth , etc . and makes those non - financials plays together as " future driving gear of corporate financial achievement " 平衡记分卡的业绩评价指标既包含财务指标，同时又通过顾客满意度、内部运作过程及组织的学习与成长等非财务指标来补充单一的财务指标，并由这些处在因果关系链上的非财务指标共同作为公司“未来财务绩效的驱动器” 。
