在齿輪滾銑生产中,如何縮短齿輪加工机动工时的問題,是近几年来世界各国研討的中心,將相应而采取的方法归納起来,可以看出以下几个方向:(1)使用硬質合金刀具,提高切削速度,目前已达200~335公尺/分,生产率提高5倍以上。(2)高速鋼刀具方面,主要是改进滾刀的結構和工作法。例如,苏联新克拉馬托尔斯克的斯大林机器制造厂工程师西多連柯以接触帶——滾刀外圓直徑和毛坯被加工齿槽的表面接触的部分来分析滾刀各个刀齿的負荷,改变了滾刀的結構,它的外圓不是如普通滾刀一样的直綫形,而是做成曲綫狀的(即通常所謂“进步”滾刀——校者)。使用这种滚刀有可能大大增加进給量,使粗加工齿輪的生产率提高近4~8倍。(3)加長同时参加工作的切削刃。例如“車齿法”,即用插齿刀代替泼齿刀在滾齿机上加工。采用多头滾刀,使在同样的滾刀轉数下,工作物轉数成倍地增加,但因
In the gear hobbing production, how to shorten the time of the gear processing machine is the center of research in all countries in the world in recent years, and the corresponding methods are summarized, we can see the following directions: (1) the use of cemented carbide Cutting tools to improve the cutting speed, has reached 200 to 335 meters / min, productivity increased more than 5 times. (2) high-speed steel cutting tools, mainly to improve the hob structure and working method. For example, Sidolinko, a Stalin machine shop engineer in New Kramatorysk, the Soviet Union, analyzed the load on each tooth of a hob by touching the part where the outer diameter of the hob - the hob - was in contact with the surface of the tooth being machined, Change the hob structure, its outer circle is not like a straight hob like a straight line, but made of curved (ie, the so-called “progressive” hob - school). The use of such hobs may greatly increase the amount of feed, so that the roughing gear productivity increased by nearly 4 to 8 times. (3) Lengthen the cutting edge of the work at the same time. For example, “car tooth method”, that is, instead of using a gear shaper cutter gear hobbing machine processing. The use of long hob, so that in the same hob revolutions, the number of workpieces doubled, but due to
