在当前社会主义竞赛及提高产品质量的运动中,各类机器的水平正迅速提高。为了增加齿轮箱的传递动力,缩小尺寸,延长寿命以及减小噪声等,愈来愈多的齿轮要求淬火。而且,不同精度等级的齿轮(6～7级)均希望磨齿,最好还能对齿形进行修形。但是,现有展成法磨齿工艺效率很低,成本很高。其原因是展成磨齿时,直线运动的砂轮要往复运动多次才能包络出轮齿的一个渐开线齿面。若采用成形砂轮磨齿时,砂轮往复一次就可磨出两个齿面。因而,效率要高数倍,有人甚至认为要高十余倍。而且,成形磨齿时,机床可省去展成机构。其工作情况与在万能铣床上用片铣刀铣齿轮一样。故有可能显著
In the current socialist race and the campaign to improve product quality, the level of various machines is rapidly rising. In order to increase the transmission power of the gear box, reduce the size, extend the life and reduce the noise, more and more gears require quenching. Moreover, different levels of precision gears (6 to 7) are expected to grind, it is best to modify the shape of the tooth. However, the current exhibition method grinding process is inefficient and costly. The reason is the development of grinding teeth, the linear motion of the wheel to reciprocate several times to envelop the tooth of an involute tooth surface. If the use of forming grinding wheel, the wheel can reciprocate once grinding two tooth surfaces. Therefore, the efficiency is several times higher, and some people even think that it should be ten times more high. Moreover, the formation of grinding teeth, the machine can save the formation of institutions. Its working conditions are the same as milling milling gears on a universal milling machine. It may be significant
