Model utility content
The technical problems to be solved in the utility model, be exactly for the existing deficiency of prior art, and a kind of heavy speed changing box lubricating system is provided, this lubrication system adopts double pump lubricated, its high lubricating effect, effectively raises functional reliability and the working life of gearbox.
This programme is achieved by the following technical measures: this heavy type speed changing box lubricating system comprises oil pump I and oil pump II, the inlet port I of described oil pump I is connected with main-gear box, oil outlet I is connected with auxiliary transmission by oil pipe, and the inlet port II of described oil pump II is connected with auxiliary transmission, oil outlet II is connected with main-gear box by oil pipe.
Above-mentioned inlet port I is arranged on main-gear box front portion.
Above-mentioned inlet port II is arranged on the front portion of auxiliary transmission.
Above-mentioned oil outlet I is connected with oil pipe II with case inner tube I by oil pipe I.
Above-mentioned oil pipe II is connected with case inner tube III.
Above-mentioned inlet port II is connected with oil pump II by oil pipe V.
Above-mentioned oil outlet II is connected with oil pipe III with case inner tube IV by oil pipe IV.
Above-mentioned case inner tube IV is connected with case inner tube II by oil pipe III.
On the sidewall of above-mentioned case inner tube IV, be processed with radial direction oil hole.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this heavy type speed changing box lubricating system, the inlet port I of oil pump I is connected with main-gear box, oil outlet I is connected with auxiliary transmission by oil pipe, the inlet port II of oil pump II is connected with auxiliary transmission, oil outlet II is connected with main-gear box by oil pipe, realized by this structural type: oil pump I provides pressure lubrication needed lubricant oil from main-gear box oil suction for auxiliary transmission, oil pump II provides pressure lubrication needed lubricant oil from auxiliary transmission oil suction for main-gear box.This lubrication system is compared with lubrication system in existing gearbox, the flowing velocity of lubricant oil is accelerated, and its lubrication effect is better, and can better reduce the temperature of part in casing, its cooling effect is also better, has greatly improved reliability and the working life of gearbox.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
