The lubricating oil external circulation equipment of the worm gear reducer products has lower oil temperature. The worm equipment reducer plans to traverse its power. The worm equipment is created of non-ferrous steel. Master data worms are typically produced of tough steel. Therefore, utilizing a whole lot of warmth in the software, coupled with the impact of the ambient temperature, it is difficult to handle the temperature of the reducer. Use within the temperature assortment. When the ambient temperature is lower than 0℃, the operating temperature of the worm equipment reducer ought to be managed at -40℃~40℃.
