凡转动的机械部位,装上滚珠轴承后,马上轻快省力。而滚珠轴承所需的钢珠是标准件,一般都可买到。但是,对于长期浸泡水中,要求耐锈蚀的滚珠—铜珠和不锈钢珠等是买不到的。我厂所用滚珠,外径D=φ6h,表面光洁度△9以上,椭圆度不得大于0.02。由于直径小,要求精度高,用一般加工方法难以解决。我们采用车削和研磨滚压相结合的方法,使该件达到了技术要求。我厂采用的加工程序是: 一、车削
Where the rotating mechanical parts, fitted with ball bearings, immediately light and labor-saving. The ball bearings required ball is the standard parts, generally available. However, for long-term immersion water, balls, copper balls and stainless steel balls that are resistant to corrosion are not available. I plant ball, diameter D = φ6h, surface finish △ 9 above, ovality can not be greater than 0.02. Due to the small diameter, the requirements of high precision, difficult to solve with the general processing methods. We use a combination of turning and grinding rolling method, so that the pieces meet the technical requirements. I plant processing procedures used are: First, turning
