Abstract
The utility model relates to an automatic lubricating device for a valve rocker arm of a diesel engine, which is characterized in that an oil baffle partition plate is directly casted on a radial direction of a valve tappet hole in a diesel engine body, after a flying wheel and a crank shaft of the diesel engine rotate at high speed, engine oil in the engine body is driven to shake, so that engine oil at the bottom of the engine body splashes to the partition plate, and a part of engine oil flows into from the valve tappet hole and enters an air cylinder cover along a valve push rod for lubrication. Parts such as a traditional engine oil pipe, a hollow bolt and the like are eliminated, cost is effectively reduced, and the automatic lubricating device has the characteristics of simple structure and the like, and is easy to cast.
Description
Technical field
The utility model relates to machining, particularly a kind of air-valve swinging arm of diesel engine automatic lubricator.
Background technique
The sae number of each part of diesel engine (or motor) depends on environment, the speed of related movement of this part and bears the size of mechanical load, heat load.According to the difference of degree of lubrication, several lubricating systems below engine lubrication system adopts: (1) pressure lubrication: utilize oil pump, the lubricant oil that will have certain pressure is constantly delivered between rubbing surface in a steady stream.Formation has certain thickness and can bear certain mechanical load and the oil film that do not break, two friction partss is separated fully as far as possible, realizes lubricating reliably.(2) splash lubrication: the rotation of some motion rotating part when utilizing engine operation (mainly being bent axle, camshaft or gear etc.) is taken fluid to splash lubrication needed position, it is by oil droplet and mist of oil that the part that is sealed in the cabinet has splashed lubricant oil to be formed self oiling from take friction pair to oilyly, a kind of mode that friction surface is lubricated.Splash lubrication is suitable for exposing part surface (such as casing wall or cam etc.); The part that speed of related movement is lower (such as wrist pin etc.); The part that mechanical load is lighter (such as tappet etc.).Cylinder wall adopts splash lubrication also can prevent because lubricating oil pressure is too high, and oil mass is excessive, enters the firing chamber and causes engine condition to worsen.(3) intermittent oiling:, the position that disperse not too important to some, adopt the mode of regular grease up to be lubricated, lubricated such as assemblies such as engine water pump bearing, generator, starter motor and distributors.At present, the lubricating system of the valve rocker of single cylinder diesel generally is to draw in the machine oil injected gas cylinder head cover from body hole by the machine oil pipe to lubricate, and the inventor finds, this mode complex structure, and cost is high.
Summary of the invention
The purpose of this utility model namely is to provide a kind of and can overcomes the deficiency that prior art exists, air-valve swinging arm of diesel engine automatic lubricator simple in structure.
To achieve these goals, air-valve swinging arm of diesel engine automatic lubricator of the present utility model, comprise body and valve tappet hole, be characterized in: also comprise directly and to cast in the radial direction a dividing plate that can keep off oil in the internal body valve tappet hole of diesel engine.
Compared with prior art, the beneficial effect of this air-valve swinging arm of diesel engine automatic lubricator is:
The utility model utilizes the principle of splash lubrication, keep off oily dividing plate by directly being cast with in the radial direction of the valve tappet hole in diesel-engine body, after diesel engine flywheel and crankshaft high-speed rotation, cause that the machine oil in the body rocks, the machine oil that is positioned over organism bottom splashes, because dividing plate resembles a stifled oily wall and stands in the body, so, the machine oil that splashes is just directly brought into valve tappet and valve actuating push rod by the inner chamber of body, thereby arrival rocking arm, realization is lubricated to valve and rocking arm, this air-valve swinging arm of diesel engine automatic lubricator is owing to cancelled traditional machine oil pipe, the parts such as hollow bolt, effectively reduce cost, have simple in structurely, cast the characteristics such as easy.
Description of drawings
Fig. 1 is the main TV structure simplified schematic diagram of the utility model air-valve swinging arm of diesel engine automatic lubricator.
Fig. 2 is the sectional structure simplified schematic diagram of A-A of Fig. 1.
Fig. 3 is main TV structure simplified schematic diagram of the embodiment 1.
Component title and sequence number among the figure:
Body 1, the oily dividing plate 2 of gear, valve tappet hole 3, machine oil 4, cooling system 5, cylinder head assembly 6, Piston and rod assembly 7, crankshaft-flywheel assembly 8, camshaft 9, valve tappet 10, valve actuating push rod 11.
Embodiment
Below in conjunction with drawings and Examples structure of the present utility model is described.
Shown in accompanying drawing 1～2, air-valve swinging arm of diesel engine automatic lubricator of the present utility model, comprise body 1, the oily dividing plate 2 of gear and valve tappet hole 3, keep off valve tappet hole 3 that oily dividing plate 2 is cast directly in diesel-engine body 1 inside in the radial direction, after utilizing the rotation of diesel engine flywheel and crankshaft high-speed, cause that the machine oil in the body 1 rocks, so that the machine oil 4 of body 1 bottom splashes, splash the oily dividing plate 2 of gear, keep off oily dividing plate 2 tops and divide machine oil 3 inflows from valve fore-set hole, enter the purpose that reaches lubricated in the valve mechanism cover along valve actuating push rod 11.
Embodiment 1
In December, 2011, the body 1 that the inventor will be cast with the oily dividing plate 2 of gear is used on the YC180A diesel engine, shown in accompanying drawing 3, the YC180A diesel engine comprises cooling system 5, cylinder head assembly 6, Piston and rod assembly 7, crankshaft-flywheel assembly 8, camshaft 9, valve tappet 10 and valve actuating push rod 11, by having adopted this air-valve swinging arm of diesel engine automatic lubricator, greatly descended from the cost that body hole draws lubricating fitting in the machine oil injected gas cylinder head cover than the original machine oil pipe that passes through.Over 4 months, according to customer response, the lubrication system of YC180A diesel engine obviously is improved.
Claims (1)
1. an air-valve swinging arm of diesel engine automatic lubricator comprises body (1) and valve tappet hole (3), it is characterized in that: also comprise directly and keep off oily dividing plate (2) being cast with in the radial direction of body (1) inner valve tappet hole (3) of diesel engine.
