Abstract
A lubricating structure for the crankshaft connecting rod neck of single-cylinder diesel engine features that an oil pump driven by cam shaft is additionally arranged at the inner side of gear chamber cover, the oil sucking inlet of oil pump is communicated with the bottom of casing via oil sucking channel, the oil outlet of oil pump is communicated with small jet hole via oil outlet channel, and the outlet of small jet hole is correspondent to the timing gear of cam shaft or crankshaft. The single cylinder diesel engine with the lubricating structure is matched with fixed operation machinery or walking operation machinery, as long as engine oil is stored in a diesel engine box body, an oil pump can pump out the engine oil and spray the engine oil to a camshaft timing gear or a crankshaft timing gear set from a small injection hole, so that the engine oil can be ensured to be sequentially sent to a crankshaft main bearing, a crankshaft oil slinger and a crankshaft connecting rod neck by the pair of gears meshed with each other, and the occurrence of serious accidents such as tile biting and the like caused by oil loss of a kinematic pair can be effectively prevented.
Description
Technical field:
The present invention relates to a kind of single cylinder diesel, be particularly useful for the single cylinder diesel of supporting walking Work machine.
Background technique:
In single cylinder diesel, the lubricated of crank-shaft link neck and connecting rod bearing shell relative movement pair is the emphasis problem that the single cylinder diesel lubrication system need solve.At present, the lubricating oil that single cylinder diesel is used for crank-shaft link neck and connecting rod bearing shell kinematic pair obtains by following approach: camshaft timing gear partly immerses below the interior machine oil liquid level of casing, be meshed with crankshaft timing gear simultaneously, during diesel engine work, camshaft timing gear is constantly taken machine oil out of, be meshing with each other through gear the machine oil that sticks to gear surface is extruded, the machine oil that is extruded enters crankshaft main bearing, crankshaft oil slinger and crank-shaft link neck oilhole successively, thereby realizes the lubricated of this kinematic pair.This oil lubricating supply pathway structure is simple, low cost of manufacture, and also machine oil squeezes by nibbling of high speed rotating engaging gear and makes the mechanical admixture that has in the machine oil effectively be separated and pulverize.Facts have proved that this lubrication system is a mature and reliable to the single cylinder diesel of fixed operation, it is widely used.But when single cylinder diesel be matched in the walking operation mechanical the time; as microtractor, field tillage machine etc.; because this class running mechanism is in operation process; occur rising and falling through regular meeting; when heeling condition appears in diesel engine; just can cause camshaft timing gear detachment machine pasta; this moment, lubricating oil then can't be sent into the crank-shaft link neck kinematic pair through camshaft timing gear; cause oil-break to sting a watt fault; therefore single cylinder diesel only depends on existing lubricating system, can not satisfy the supporting requirement with the walking Work machine.
Summary of the invention:
In order to overcome existing single cylinder diesel above shortcomings, the invention provides a kind of lubricating structure of crank-shaft link neck of single-cylinder diesel engine, adopt such lubricating structure, single cylinder diesel does not have appoints and the fixed operation machinery support, still supporting with the walking Work machine, the lubricated of crank-shaft link neck kinematic pair can not stung watt because of losing oil.
The lubricating structure of crank-shaft link neck of single-cylinder diesel engine of the present invention, comprise casing, gear chamber cover, camshaft, camshaft timing gear, bent axle, crankshaft timing gear, crankshaft main bearing, oil thrower ring, connecting rod bearing shell and connecting rod, it is characterized in that: set up an oil pump in the inboard of gear chamber cover, oil pump is by camshaft actuated, the inlet port of oil pump communicates with bottom half machine oil by the oil suction road, the oil outlet of oil pump communicates with jet apertures by oil road, and the outlet of jet apertures is corresponding with camshaft timing gear or crankshaft timing gear.
Owing to set up oil pump in the inboard of gear chamber cover, oil pump is by camshaft actuated, the inlet port of oil pump communicates with bottom half by the oil suction road, the oil outlet of oil pump communicates with jet apertures by oil road, and the outlet of jet apertures is corresponding with camshaft timing gear or crankshaft timing gear.Thereby nothing is appointed a single cylinder diesel and a fixed operation machinery support, still supporting with the walking Work machine, when even the inclination working state appears in diesel engine, oil pump can both be extracted machine oil out, spray to camshaft timing gear or crankshaft timing gear group from jet apertures, so just can guarantee that this adheres to machine oil all the time to the pitch wheel surface and machine oil extruded enters crankshaft main bearing, crankshaft oil slinger and crank-shaft link neck successively, thereby guarantees the lubricated of this kinematic pair.
Description of drawings:
Fig. 1 is the schematic representation of existing crank-shaft link neck of single-cylinder diesel engine lubricating system;
Fig. 2 is a structural representation of the present invention;
Among the figure: the 1-casing; The 2-gear chamber cover; The 3-oil pump; The 4-camshaft; The 5-bent axle; The 6-crankshaft timing gear; The 7-camshaft timing gear; The 8-oil road; 9-oil suction road; The 10-jet apertures; 11-machine oil; 12 oil thrower rings; The 13-crankshaft main bearing; The 14-bearing shell; The 15-connecting rod; 16-crank-shaft link neck oilhole.
Embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention:
The lubricating structure of crank-shaft link neck of single-cylinder diesel engine of the present invention, comprise casing 1, gear chamber cover 2, camshaft 4, camshaft timing gear 7, bent axle 5, crankshaft timing gear 6, crankshaft main bearing 13, oil thrower ring 12, bearing shell 14 and connecting rod 15, an oil pump 3 is housed in the inboard of gear chamber cover 2, oil pump 3 is driven by the end face of camshaft 4, the inlet port of oil pump 3 communicates by the bottom of oil suction road 9 with casing 1, the oil outlet of oil pump 3 communicates with jet apertures 10 by oil road 8, the outlet alignment cam axle timing gear 7 of jet apertures 10 and the engagement place of crankshaft timing gear 6.
Its working procedure is as follows: camshaft 4 driving machine oil pumps 3, oil pump 3 is extracted machine oil 11 by oil suction road 9 out from bottom half, machine oil 11 ejects from oil outlet, oil road 8 and the jet apertures 10 of oil pump 3, the engagement place of the outlet of jet apertures 10 and camshaft timing gear 7 and crankshaft timing gear 6, lubricating oil 11 is sent into crankshaft main bearing 13, oil thrower ring 12 through the gear train extruding, be transported to bearing shell 14 from crank-shaft link neck oilhole 16, thereby guarantee the lubricated of crankshaft journal and 14 kinematic pair of bearing shell.
