The lubricating oil external circulation gear of the worm equipment reducer gear has lower oil temperature. The worm equipment reducer programs to traverse its electrical power. The worm equipment is made of non-ferrous metallic. Master data worms are typically made of challenging metal. Therefore, using a great deal of warmth in the software, coupled with the affect of the ambient temperature, it is tough to management the temperature of the reducer. Use within the temperature assortment. When the ambient temperature is reduced than 0℃, the doing work temperature of the worm equipment reducer need to be managed at -40℃~40℃. It is recommended to warmth or use a lower freezing point lubricant ahead of the oil is fully dissolved.
