我公司一台CY5112单柱工作台移动立式车床,电机扭矩经Ⅰ轴齿轮4×39/4×20传递给减速器。齿轮副靠减速器外端面,原结构没有润滑系统,电机输出轴功率大、转速高,齿轮使用寿命受到严重影响,曾因齿轮磨损,需连夜采购,通宵突击抢修的情况,再者,更换齿轮须将工作台及以下部件全部吊起才能拆下,工作量相当大。1984年该设备安排大修,进行了改进(如图),在减速器集油槽底部铆-φ6铜管,其一端穿过箱壁至齿轮上方,使油滴在齿轮上。改善了润滑条件,保证了该齿轮良好润滑,而改 My company a CY5112 single-column table mobile vertical lathe, the motor torque through the Ⅰ-axis gear 4 × 39/4 × 20 passed to the reducer. Gear pair by the outer surface of reducer, the original structure without lubrication system, the motor output shaft power, high speed, gear life is seriously affected, had gear wear, need overnight purchase, overnight assault repair, and then replace the gear Workbench and the following components must be lifted to be removed, the workload is quite large. In 1984, the equipment was overhauled and improved (pictured). At the bottom of the reducer sump, a rivet -φ6 copper tube was inserted through one end of the tank wall above the gear so that the oil dripped onto the gear. Improved lubrication conditions to ensure good lubrication of the gear, and change
