各种传动的特点
1.齿轮传动
优点：1）适用的圆周速度和功率范围广；2）传动比准确；3）机械效率高；4）工作可靠；5）寿命长；6）可实现平行轴、相交轴、交错轴之间的传动；7）结构紧凑
缺点：1）要求有较高的制造和安装精度,成本较高；2）不适宜于远距离两轴之间的传动
2.带传动
多是利用摩擦原理进行工作的,它适用于圆周速度较高和圆周力较小时的工作条件
同步带传动是带传动中的一种形式,属于啮合型传动带,没有弹性滑动,可用于要求有准确传动比的地方；所需的张紧力小； 允许有较高的线速度和较小的带轮直径,可获得较大的传动比；有较高的传动效率,但其对制造和安装精度要求较高,成本也较高
3.链传动
链传动是利用链轮轮齿与链条的啮合来实现传动的,它适用于圆周速度较低和圆周力较大时的工作条件
链传动属于带有中间挠性件的啮合传动.它具有能够保持准确的平均传动比,结构比较紧凑,作用于轴上的径向压力较小,承载能力较大和传动效率较高,在极其恶劣的工作条件下仍能很好地工作等优点.但链传动存在链节易磨损而使链条伸长,从而造成跳齿,甚至脱链,不能保持恒定的瞬时传动比,工作时有噪音,不宜在载荷变化大和急速反向的传动中应用等缺点

All kinds of transmission characteristics
1. Gear
Advantages: 1) applicable circumference speed and power range; 2) ratio accurate; 3) mechanical high efficiency; 4) reliable work; 5) long life. 6) can implement parallel axis, intersection between axial and staggered shaft transmission; 7) compact structure
Faults: 1) to a higher manufacturing and installation accuracy, cost is higher; 2) disagrees with distance between two axis of transmission
2. Belt transmission
Using a friction principle is more work, it applies to the circumferential velocity is higher and more hours of work circle force conditions
Synchrobelt transmission is a form of belt transmission, belong to mesh type belt, no elastic slide, can be used to require a accurate ratio areas; The tensioner force required for small; Allow a higher velocity and smaller belt wheel diameter can acquire larger ratio; Have high transmission efficiency, but its manufacturing and installation higher accuracy, cost is higher also
3. Chain
Chain is use of mesh with the chain sprocket teeth to achieve transmission, it applies to the circumferential velocity is low and the circular force bigger when working conditions
Chain with flexible thing belonging to the middle of meshing transmission. It has to keep accurate average velocity ratio, the structure is compact, actions on shaft radial stress is lesser, carrying capacity and transmission efficiency is higher, large in extremely bad working conditions can still work very well, etc. But chain exist chain wear easily and make chain section, causing elongation jumping gears, and even take off, can't keep the chain of the instantaneous velocity ratio, constant tome noise, unfavorable work
