Description
Technical field:
The utility model relates to a kind of single cylinder diesel, is particularly useful for cylinder diameter at the single cylinder diesel more than 95 millimeters.
Background technique:
In cylinder diameter is single cylinder diesel more than 95 millimeters, at the bent axle brachycephaly crankshaft timing gear is housed, during the diesel engine proper functioning, all gears drive by crankshaft timing gear in the driving gear set, the drive connection of diesel engine driving gear set as shown in Figure 1, this driving gear set is by crankshaft timing gear 9, starting gear 10, camshaft gear wheel 11, speed regulation gear 12, last balance shaft gear 13 and following balance shaft gear 14 are formed, speed regulation gear 12 and crankshaft timing gear 9, starting gear 10, camshaft gear wheel 11 and following balance shaft gear 14 mesh simultaneously, starting gear 10 and last balance shaft gear 13 engagements.On this class diesel engine, the lubricated of driving gear set is to lubricate by the mist of oil that the lubricant oil that the crank-shaft link neck of single-cylinder diesel engine forced lubricating system overflows at home and abroad forms when the bent axle high speed rotating, by the resuscitation apparatus on the gear chamber cover mist of oil is sucked in the gear chamber, thereby driving gear set is lubricated, this lubricating system oil mass is few, reliability is very low, diesel engine is when work, because the poor lubrication of driving gear set, gear tooth noise is very big, friction velocity is fast between gear, causes the machine temperature higher, and the working life of driving gear set is short.This is the common fault of cylinder diameter single cylinder diesel more than 95 millimeters, in order to overcome this defective, drawing a high-pressure unit oil pipe outside someone adopts from lubricant pump is connected on the gear chamber cover, with the oil outlet tube hydraulic fluid port to living driving gear set, the difficulty of this scheme implementation is bigger, not only to increase external high-pressure oil pipe, also will be to the gear chamber cover processing of holing, the cost of every machine will increase by 10～15 yuan, and the not all type of this improvement project can both implement, and is all right obstructed as types such as condensing type diesel engine, electric starter types.Understand according to the claimant, up to the present, also do not have a kind of both economical and reliable solution.The claimant has carried out conscientious research and analysis by the lubrication system to existing diesel, has found the lubricated scheme of a kind of effective solution diesel engine driving gear set.
The model utility content:
The purpose of this utility model provides a kind of forced lubrication structure for transmission gear set of single-cylinder diesel engine, adopt such lubricating structure, the lubricated oil that loses can not appear in driving gear set, gear tooth noise and machine temperature have not only been reduced, and wear resistance and the working life that can improve driving gear set, do not increase cost again, not only economy but also practicality.
A kind of forced lubrication structure for transmission gear set of single-cylinder diesel engine, it is characterized in that: it comprises the long head supporting diameter of axle, crankshaft journal, the brachycephaly supporting diameter of axle, the gear diameter of axle, oil input channel, bent axle oil pocket, oil road, brachycephaly bearing and crankshaft timing gear, oil input channel and bent axle oil pocket interlink, one end and the bent axle oil pocket of oil road interlink, the other end is arranged on the surface of the brachycephaly supporting diameter of axle, be provided with oil groove at the brachycephaly supporting diameter of axle with the section of cooperation of brachycephaly bearing, one end of oil groove communicates with the oil outlet of oil road, and the other end is to living the Surface of action of crankshaft timing gear.
Further, described oil groove is opened on the surface of the brachycephaly supporting diameter of axle.
Further, described oil groove is opened on the bore area that brachycephaly bearing and the brachycephaly supporting diameter of axle cooperates.
Further, the sectional shape triangle of described oil groove.
Diesel engine pressure lubrication oil pump is imported lubricant oil by oil input channel to the bent axle oil pocket, lubricant oil is input to the surface of the brachycephaly supporting diameter of axle from oil outlet by oil road, because the oil outlet of oil groove and oil road interlinks, lubricant oil can be ejected on the flank of tooth of crankshaft timing gear from the oil groove straight line, because crankshaft timing gear drives speed regulation gear, and speed regulation gear drives starting gear simultaneously, camshaft gear wheel and following balance shaft gear, starting gear drives balance shaft gear again, begin to lubricate from crankshaft timing gear and speed regulation gear engagement place from the lubricant oil of oil groove ejection, again by the lubricated starting gear of speed regulation gear, camshaft gear wheel and following balance shaft gear, by the lubricated again balance shaft gear of going up of starting gear, so just can successfully be lubricated at last all gears in the driving gear set of diesel engine.This lubricating structure can not only thoroughly improve the lubricating condition of diesel engine driving gear set, and improved the lubricating condition of all the lining cooperation places on camshaft, starting shaft, the speed governing axle, this scheme does not need to increase any part, only with hand is carried bistrique and is offered an oil groove get final product on the brachycephaly supporting diameter of axle, 0.1 yuan of the cost less than that increases increases cost hardly.Not only economy but also practicality prove through claimant's repetition test, adopt this lubricating structure, almost can't hear the engagement driving noise of diesel engine, start lightly, and the machine temperature decreases, and can improve more than 20% the working life of driving gear set.
