蜗杆传动装置的润滑,既要保持蜗杆传动散热良好,温升低,又要具有足够的粘度或油性,以增强抗粘着磨损的能力。重载、低速的蜗杆传动装置采用低粘度50号机械油添加油性剂集中循环润滑较好,还可采用28号轧钢机油灌注式润滑,效果也较理想。如我公司冷床蜗杆传动是中心距为420毫米的球面蜗轮副,原用45号机械油集中润滑,但箱体温度较高,铜蜗轮上啮合部位常有金属烧熔撕裂的痕迹,钢蜗杆上常粘有铜末,粘着磨损严重。64年,我们改为灌注式润滑,在50号机械油中添加了1～3%的硫化鲸鱼油,粘着情况有了明显的改善。
Worm gear lubrication, it is necessary to keep the worm drive heat dissipation, low temperature, but also have sufficient viscosity or oil, in order to enhance anti-adhesive wear ability. Heavy-duty, low-speed worm gear with a low viscosity of 50 mechanical oil added oily agent concentrated circulation lubrication is better, can also be used on the 28th rolling oil filling lubrication, the effect is also more satisfactory. Such as my company’s cold bed worm drive center distance 420 mm spherical worm gear, the original 45 oil lubrication, but the box body temperature is high, the copper worm gear meshing often metal burning tearing marks, steel Worm often sticky copper, adhesive wear serious. In 64 years, we changed to perfusion lubrication, adding 50% of the mechanical oil 1% to 3% of the whale oil, the adhesion has been significantly improved.
