rim speed
Examples
- Driving elements ; circumferential speeds
传动元件.圆周速度 - Power take - off pulley for agricultural tractors - peripheral speed and width
农业拖拉机动力输出皮带轮圆周速度和宽度 - Generally high speed gear is that circumference speed exceeds 25m / s . it is execesively applied in power transmission equipment and other kinds of machineries
通常将圆周速度大于25m s的齿轮或旋转速度超过3000r min的齿轮称为高速齿轮，它广泛应用于透平机械及其他机械中。 - Haloes in the two accretion phases show systematically different properties , for example , the circular velocity vh increases rapidly with time and approximately equals the inner circular velocity vs in the fast accretion phase , but remain almost constant and less than vs in the slow accretion phase : the inner properties of a halo , such as rs and ms increase rapidly with time in the fast accretion phase but change only slowly in the slow accretion phase : the halo concentration changes slow in the fast accretion phase , but increases rapidly with the hubble expansion in the slow accretion phase . the inner structure and potential well associated with a halo is built up mainly in the fast accretion phase , while a large amount of mass can be accreted in the slow accretion phase without changing significantly the inner properties and the potential well
~ 4 ，其束缚能和具有相同圆周速度的等温球大致相等; ( s )在这两个阶段，暗晕的行为特征迥异(例如，圆周速度均‘在快速吸积阶段增长迅速且略大于内部圆周速度: 、 ，而在缓慢吸积阶段基本恒定甚至降低，且小于、 、 . : 、和呱在快速吸积阶段增长迅猛，而在缓慢吸积阶段增长滞缓) : ( l )一个暗晕的内部结构和引力势阱主要是在早期的快速吸积阶段成长起来的，虽然在缓慢增长阶段可以吸积大量的质量(超过10倍) ，但这并不显著地改变其内部特征和引力势阱 - This phenomenon makes the circumferential velocity of the driven wheel be slower than the drive wheel ' s decrease the efficiency of the belt drive abrade the belt and shorten its life . so , it is very important for those who design and use it to know and understand qualitatively and quantitatively the phenomenon of elastic slippage
弹性滑动的存在使从动带轮上的圆周速度低于主动带轮上的圆周速度，带传动效率降低，带磨损和工作寿命缩短，因此，定性和定量地认识和理解带传动中的弹性滑动现象对于带传动的设计和使用是十分重要的。
