the V-belt is an important element in the field of power transmission.It is continually being improved by the various manufacturers and loading values are revised from time to time.The designer generally is guided by the current literature for the particular brand of belt he expects to use.The forgoing development should be considered a methed that shows how the fatigue life of a belt is influenced by factors such as bending,centrifugal effects,and power transmitted.
A clutch is a devise for quickly and easily connecting or disconnecting a rotatable shaft and a rotating coaxial shaft.Clutches are usually placed between the input shaft to a machine and the output shaft from the driving motor,and proved a convenient means for starting and stopping the machine and permitting the driver motor or engine to be started in an unloaded state.
The rotor(rotating member) in an electric motor has rotational inertia,and a torque is required to bring it up to speed when the motor is started.If the motor shaft is rigidly connected to a load with a large rotational inertia ,and the motor is started suddenly by closing a switch,the motor may not have sufficent torque capacity to bring the motor shaft up to speed before the windings in the motor are burned out by the excessive current demands.A clutch between the motor and the load shafts will restrict the starting torque on the motor to that required to accelerate the rotor and parts of the clutch only.On some machine tools it is convenient to let the driving motor run continuously and to start and stop the machine by operating a clutch.

V带是功率传递中很重要的元件.因为各生产厂家不停地改善,所以它的载荷量也时而不时被更新.通常,机械设计者可查阅其需要使用品牌的产品手册来选择使用V带.上述的发展是应该考虑一种方法来展示皮带寿命是如何受弯曲、离心力及传动功率等因素的影响.
离合器是一种很迅速及容易连接或松开正在旋转的主动轴与另一根同心从动轴的器件,它通常用在机器的输入动力轴及电机的输出动力轴之间.离合器使启动或停止机器变得方便,并且能使电机或引擎在无负荷状态下启动.
电机的转子（转动原件之一）是有惯性的.当电机启动时,需要一个力矩使转子提升速度.如果电机轴与负荷是刚性连接,就会有更大的惯性.这样一合闸,电机在还没有足够的力矩使转子提升到一定速度,可能就被过电流烧毁了线圈.在电机和负荷之间的离合器,会限制启动转矩来保证有足够的力矩只加速转子和离合器.有些机床,可以非常方便的在电机连续运转时,通过操作离合器来启动或停止机器的.
