1. more can adapt to compact-sized gear-box by the improvement to oil duct is arranged on disc, disc made to exist
The oil thrown away in rotation process can achieve the effect that pressurization, and lubricating oil gets rid of to obtain more Gao Gengyuan；
2. a lubrication piping is arranged above disc, the oil in disc can be made to enter lubrication piping and spray,
Realize the effect of lubricating oil secondary booster, lubrication piping sprays the position that section alignment needs to lubricate, the profit of lubricating oil from top to bottom
Sliding all parts, reduce and stir heating of oil and churning loss, improve lubricating efficiency and transmission efficiency.
3. the oil duct being arranged on disc can be realized the effect of quantitative oil storage and quantitative oil suction according to the size of oil duct,
Lubricating oil in oil duct enters in lubrication piping, can be realized the effect that disc orientation gets rid of oil.
