齿轮是机器中不可缺少的一项重要另件,它的种类繁多,应用广泛,重量可自几分之一公斤直到几公吨一只.假使用毛胚翻出到铣床上去加工,在我们铸造工作者讲来,倒还不十分费事,只要铁质结实,结构均匀,没有砂眼便行了.但若需要连牙齿翻出,这事情可就麻烦得多,因为齿轮总是至少两个搭配着一起走的,若是做得不准确,那么毛病轻的,还不过声音响些,寿命短点而已,严重的却可能把牙齿都打掉,甚至引起机器其他部份的损坏,不能不特别注意.
Gear is an indispensable part of the machine, and it has a wide range of applications, ranging in weight from a few kilos up to a few metric tons. If the blank is turned out to a milling machine and worked in our foundry It is not too troublesome to say, but as long as the iron is strong and the structure is uniform, there is no trachoma, but if you need to turn out the teeth, it can be much more troublesome because the gears are always matched with at least two If you do not get it right, then you will not have to pay special attention if you do not have the correct light. However, the sound is rather loud and the life span is short. However, serious teeth may be destroyed or even damaged in other parts of the machine.
