The requirements for lubricating oil quantity of different models of worm gear reducers are mainly affected by factors such as center distance and power. Generally, there are the following differences:
By center distance :
For ordinary cylindrical worm gear reducer with a center distance of 50-100mm, the oil tank lubrication oil injection volume is 0.3-0.8L.
When the center distance is 100-160mm, the oil injection volume is 0.8-2L.
When the center distance is 160-250mm, the oil injection volume is 2-5L.
When the center distance is 250-400mm, the oil injection volume is 5-10L.
For arc cylindrical worm reducer, when the center distance is 80-125mm, the oil injection volume is about 0.5-1.5L.
When the center distance is 125-200mm, the oil injection volume is 1.5-3L.
When the center distance is 200-315mm, the oil injection volume is 3-8L.
Estimation by power : For single-stage transmission reducers, you can refer to the standard of about 0.35-0.7L of oil required for every 1kW of power transmitted. If it is a multi-stage transmission, the amount of oil required increases exponentially by stage, but this is just a rough estimate, and it also needs to be combined with factors such as actual structure and working conditions.
Overall, the larger the center distance and higher the power of the reducer, the more lubricating oil is usually required. In addition, factors such as installation method will also have a certain impact on the oil volume, such as the amount of a vertically installed reducer may be slightly higher than that of a horizontally installed.
