据不少单位反映,在Y4232C剃齿机上剃削低合金钢的齿轮时,存在齿面拉毛剃不光的缺陷。低合金钢材料具有韧、粘、硬化等特性,切削加工性能很差,这是齿面剃不光的主要原因。对此,我们采取两种措施,效果较好。一、合理选用切削用量 1.适当降低切削速度从国内剃齿情况来看,切削速度只能选择得低些,一般都在10～20m/min左右。考虑到低合金钢材质的特性,其切削速度最好再下降60～70%为宜。现在以油泵直齿轮m=5.5、z=12,剃齿刀z=29、d_0=165.127、β_0=15°、n_0=50为例,剃削速度为6.71m/min。采取了降低剃刀转速的办法,特别对模数较
According to many units, when shaving a low-alloy steel gear on a Y4232C shaving machine, there is a defect that the tooth surface is not shaved. Low-alloy steel with tough, sticky, hardening and other characteristics, poor machinability, which is not the main reason shave shaved. In this regard, we take two measures, the effect is better. First, a reasonable choice of cutting 1. Appropriate to reduce the cutting speed From the situation of domestic shaving, the cutting speed can only be selected lower, generally 10 ~ 20m / min or so. Taking into account the characteristics of low-alloy steel material, the cutting speed of the best descending 60 to 70% is appropriate. Now with pump spur gear m = 5.5, z = 12, shaving cutter z = 29, d_0 = 165.127, β_0 = 15 °, n_0 = 50 as an example, the shaving speed of 6.71m / min. Taken to reduce razor speed approach, especially on the modulus comparison
