随着国内外建材市场需求的不断增长,磨机、回转窑用的大模数、大规格、高精度齿轮的制造量在逐年上升,其中大型斜齿轮的数量占到65％以上,精度等级已提高到8级,制造难度相应增加。例如,目前为美国SWEDALA公司制造的直径7.468m、重量达31.85t的大齿轮装置。但在实际加工过程中,还会因种种原因出现各种各样的问题。
With the continuous growth of domestic and international market demand for building materials, mill, rotary kiln with a large modulus, large size, high precision gear manufacturing volume increased year by year, of which the number of large helical gears accounted for more than 65% accuracy level Increased to 8, a corresponding increase in manufacturing difficulty. For example, currently a large gear device with a diameter of 7.468m and a weight of 31.85t, manufactured by SWEDA, USA. However, in the actual processing, but also for a variety of reasons, a variety of problems.
