Abstract
The utility model discloses a single-cylinder diesel engine capable of sufficiently lubricating a drive gear set, which comprises a crankshaft and a driving gear set, wherein the short head of the crankshaft is also provided with a transverse oil hole communicated with an oblique oil hole; the tooth root part of a crankshaft timing gear is provided with small oil holes communicated with the transverse oil hole; the small oil holes and keyways on the crankshaft timing gear form dislocation distribution. Because the short head of the crankshaft is provided with the transverse oil hole communicated with the oblique oil hole, and the tooth root part of the crankshaft timing gear is provided with the small oil holes communicated with the transverse oil hole, the pressure lubrication of the crankshaft timing gear is realized by using the oil path for the existing pressure lubrication of the diesel engine; simultaneously, the lubricated conditions of a starting gear positioned above the utility model and an upper balancing shaft gear are greatly improved so that the combination of splash lubrication and pressure lubrication of the driving gear set of the whole diesel engine is realized so as to sufficiently lubricate the driving gear set of the diesel engine.
Description
One, technical field:
The utility model relates to a kind of single cylinder diesel, specially refers to the single cylinder diesel that a kind of driving gear set adopts pressure lubrication and splash lubrication to combine.
Two, background technique:
At present in the single cylinder diesel of cylinder diameter more than or equal to 95mm, many significant points have all adopted the lubricating system of pressure lubrication, locate all to have realized pressure lubrication as two main journals, crank-shaft link neck and cylinder head sub-assembly etc. on the crankshaft component, what be positioned at that the diesel engine driving gear set of gear chamber cover then adopts is splash lubrication.Because driving gear set is made up of balance shaft gear on camshaft gear wheel, speed regulation gear, crankshaft timing gear, the starting gear and following balance shaft gear, and crankshaft timing gear, starting gear and last balance shaft gear are in apart from the higher position of machine oil face, thereby the phenomenon of driving gear set lack of lubrication appears often, thereby make the transmission noise of diesel engine driving gear set increase, transmission efficiency descends, gear wear is accelerated, and descend to working life.
Three, summary of the invention:
Goal of the invention of the present utility model is to provide the single cylinder diesel of a kind of driving gear set energy sufficient lubrication.
Its lubricating system changes pressure lubrication into by existing simple splash lubrication and adds splash lubrication.
The utility model is to realize the foregoing invention purpose by following technical solution.
The single cylinder diesel of the utility model driving gear set energy sufficient lubrication, comprise bent axle and driving gear set, driving gear set is made up of camshaft gear wheel, speed regulation gear, crankshaft timing gear, starting gear, following balance shaft gear and last balance shaft gear, connection drive connection between them is identical with existing single cylinder diesel, wherein crankshaft timing gear is installed in the left end of bent axle brachycephaly, passes through key connecting between the two; Connecting rod neck center at bent axle is provided with accumulator, be provided with inclined oil hole of air at the bent axle brachycephaly, be provided with inclined oil hole of air at the long head of bent axle, and two inclined oil hole of air all communicate with accumulator, also be provided with horizontal oilhole at the bent axle brachycephaly, horizontal oilhole communicates with inclined oil hole of air, is provided with little oilhole in the tooth root portion of crankshaft timing gear, this little oilhole communicates with horizontal oilhole, and the keyway on little oilhole and the crankshaft timing gear is dislocatedly distributed.
Because the bent axle brachycephaly is provided with the horizontal oilhole that communicates with inclined oil hole of air, offered the little oilhole that communicates with horizontal oilhole at the tooth root place of crankshaft timing gear, thereby the oil duct that can utilize the existing pressure lubrication of diesel engine is realized the pressure lubrication of crankshaft timing gear, simultaneously the starting gear above being positioned at and the lubricating condition of last balance shaft gear there is bigger improvement, make whole diesel engine driving gear set realize splash lubrication and pressure lubrication combination, thereby it is lubricated more fully that the diesel engine driving gear set is obtained.
Four, description of drawings: Fig. 1 is for being equipped with the structural representation of the bent axle of crankshaft timing gear in the utility model; Fig. 2 is the transmission distribution map of driving gear set in the utility model; 1-accumulator among the figure; 2-bent axle brachycephaly inclined oil hole of air; The long inclined oil hole of air of 3-bent axle; The little oilhole of 4-; The horizontal oilhole of 5-; The 6-camshaft gear wheel; The 7-speed regulation gear; The 8-crankshaft timing gear; The 9-starting gear; Balance shaft gear under the 10-; The last balance shaft gear of 11-; 12-silently; Keyway on the 13-crankshaft timing gear.
Five, specific embodiments:
Below in conjunction with accompanying drawing mode of execution of the present utility model is elaborated.The single cylinder diesel of the utility model driving gear set energy sufficient lubrication, comprise bent axle and driving gear set, driving gear set is made up of camshaft gear wheel 6, speed regulation gear 7, crankshaft timing gear 8, starting gear 9, following balance shaft gear 10 and last balance shaft gear 11, its link position is identical with existing single cylinder diesel with drive connection, wherein crankshaft timing gear is installed in the left end of bent axle brachycephaly, passes through key connecting between the two; Connecting rod neck center at bent axle is provided with accumulator 1, be provided with inclined oil hole of air 2 at the bent axle brachycephaly, be provided with inclined oil hole of air 3 at the long head of bent axle, and inclined oil hole of air 2 and inclined oil hole of air 3 all communicate with accumulator 1, also are provided with horizontal oilhole 5 at the bent axle brachycephaly, and horizontal oilhole 5 communicates with inclined oil hole of air 2, be equipped with silently 12 in the left side of horizontal oilhole 5, tooth root portion at crankshaft timing gear is provided with a little oilhole 4, and this little oilhole 4 communicates with horizontal oilhole 5, and the keyway 13 on little oilhole 4 and the crankshaft timing gear is dislocatedly distributed.
