我公司的一台CW6180×1500车床床头箱皮带轮轴的法兰式轴承座漏油,需经常更换三角皮带。油液漏在电动机上,也影响电动机的正常运转和使用寿命。 一、原因 经检查测量,发现分油环内孔及装分油环的轴颈磨损,造成配合间隙增大,油液从间隙处流出;三角皮带轮和法兰式轴承座之间靠回油槽密封,有少量油液可经回油槽内油孔流回床头箱,当油量多时便回油不畅,油液沿法兰式轴承座流向床头箱外而造成漏油。 My company’s a CW6180 × 1500 lathe headstock pulley shaft flange bearing leaks, the need to frequently replace the V-belt. Leakage in the motor oil, but also affect the normal operation of the motor and service life. First, the reasons for the inspection and measurement, found that the sub-oil ring and the installation of the oil ring shaft neck wear, resulting in increased clearance with the oil from the gap at the outflow; V-belt pulley and the flange between the oil seal back seat , A small amount of oil can be returned to the headstock through the oil hole back to the headstock, when the amount of oil will return poor, fluid along the flange to the bedside headstock leakage caused.
