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。
In addition , under high sintering temperatures , iron powder can result in the graphitization of diamonds . these two reasons will affect the mechanical properties of the metal bond and its retention capacity . as a result , the wear resistance of metal bond is poor and diamond grits can be easily pulled out from the matrix , thereby shortening the life of the saw - blade 而且在高温下,铁粉会对金刚石产生较严重的化学侵蚀,这两方面的原因都会影响结合剂本身的力学性能及其对金刚石的有效把持,导致锯切过程中结合剂耐磨性差,金刚石容易脱落,使锯片寿命缩短。
