我厂于70年代初购进1台芜湖重型机床厂生产的C5225型双柱立式车床,现已使用近20年。主要用于大直径工件的外圆及端面加工。但自1982年起,我厂改产XMZ型全自动压滤机,该产品的主要零件——滤板、头板、尾板的加工均由该设备来完成。从零件图(附图)中可以看出,零件的加工过程是断续切削,工作台每转一周都要承受4次冲击载荷,由于原设备主传动系统与电机的联接是刚性柱销联接,因此车削时冲击噪声很大(有时可达100dB以上)。又由于无过载保护装置,导致了变速箱内经常性的打齿现象。几乎每隔月余就损坏1次齿轮,最严重的1次共损坏了3件齿
I plant in the early 70s purchased a heavy machine tool factory in Wuhu C5225 double-column vertical lathe, has been used for nearly 20 years. It is mainly used for the machining of the outer circle and end face of large diameter workpieces. However, since 1982, I converted XMZ automatic filter plant, the main components of the product - filter plate, head plate, tail plate processing by the equipment to complete. As can be seen from the parts drawings (with photos), the machining process of the parts is intermittent cutting, the impact load of the worktable is subjected to 4 times per revolution, since the connection between the main drive system of the original equipment and the motor is the rigid pin connection, Therefore, the impact of noise when turning a lot (sometimes up to 100dB or more). And because there is no overload protection device, led to the gear box regular hit phenomenon. Almost every month more than a gear damage, the worst one total damaged three teeth
