Abstract
The utility model relates to a two cylinders diesel engine, wherein a transmission gear group is capable of full lubrication and the transmission relationship among each gear of the transmission gear group is identical with that of the two cylinders diesel engine; an oil storage tank is provided on the bushing; an axial and a radial pinholes are provided on the inert gear axis, wherein the axial pinhole is communicated with both the radial pinhole and the oil hole on the engine body; the radial pinhole is communicated with the oil storage tank on the bushing; a gear surface lubrication hole is provided on the inert gear and is opposite to the radial pinholes, wherein the gear surface lubrication hole is communicated with the radial pinhole once the inert gear rotate for a lap. The utility model has the advantages that a forced lubrication to the rotation hole and gear surface of the inert gear with the stressed lubricating oil channel on the diesel engine body is realized by the adoption of the mentioned lubrication structure, and the lubricant condition of the camshaft gear the crankshaft timing gear and the fuel oil pump gear around the inert gear are greatly improved, and a more sufficient lubrication of the transmission gear group is realized by a combination of splash lubrication and forced lubrication of the whole transmission gear group of the diesel engine.
Description
Technical field:
The utility model relates to a kind of two cylinder diesels.
Background technique:
At present in two cylinder diesels, many significant points have all adopted the lubricating system of pressure lubrication, locate all to have realized pressure lubrication as the main journal on the bent axle, rod journal and cylinder head sub-assembly etc., the lubricating system that is positioned at the diesel engine driving gear set of gear chamber then adopts splash lubrication.Driving gear set is made up of camshaft gear wheel, idle gear, crankshaft timing gear, fuel pump gear, originally this driving gear set is by machine oil that splashes and the machine oil that is sprayed by the spiral chute between idle gear and the idle gear axle, lubricate whole train of gearings, but owing to there is the defective of oil spout direction and oil spout structure, the phenomenon that the train of gearings lack of lubrication usually occurs, thereby make the rotational noise of diesel engine driving gear set increase, gear wear is accelerated, and descend to working life.
Summary of the invention:
Goal of the invention of the present utility model is: provide two cylinder diesels of a kind of driving gear set energy sufficient lubrication, to overcome existing two cylinder diesel above shortcomings.
The utility model is achieved by the following technical solution.
Two cylinder diesels of driving gear set energy described in the utility model sufficient lubrication, comprise driving gear set and idle gear axle, described driving gear set is by camshaft gear wheel, idle gear, crankshaft timing gear, the fuel pump gear is formed, drive connection between each gear is identical with existing two cylinder diesels, idle gear is installed on the idle gear axle by lining, it is characterized in that: on the lining of idle gear axle, be provided with oil storage tank, on the idle gear axle, be provided with axial aperture and radial hole, axial aperture both communicated with radial hole, communicate with oil hole on the body again, radial hole communicates with oil storage tank on the lining, on idle gear, also be provided with the lubricated aperture of the flank of tooth of radial arrangement, the lubricated aperture of the flank of tooth is corresponding with the radial hole on the idle gear axle, the moving circle of idle gear revolution, and the lubricated aperture of the flank of tooth communicates once to aperture with the idle gear diameter of axle.
Owing to adopted above-mentioned lubricating structure, thereby can utilize existing pressure lubrication oil duct on the diesel-engine body, the flank of tooth to kinematic pair between idle gear and the idle gear axle and idle gear is carried out pressure lubrication, can also improve simultaneously the lubricating condition of the camshaft gear wheel that is positioned at around the idle gear, crankshaft timing gear, fuel pump gear, make whole diesel engine driving gear set realize that splash lubrication and pressure lubrication combine, driving gear set obtains lubricated more fully.
