Abstract
The utility model discloses a lever lubricating mechanism of a vertical single-cylinder diesel engine, which comprises a valve rocker-arm, a rocker-arm shaft and a rocker-arm base, wherein the valve rocker-arm is supported at two ends of the rocker-arm shaft which is fixed on the rocker-arm base; the valve rocker-arm is provided with an oil drain hole, the inner hole of the valve rocker-arm is internally provided with a shaft housing, and an oil drain port corresponding to the oil drain hole is arranged on the shaft housing and communicated with the oil drain hole on the valve rocker-arm in an abutt-jointing way. By adopting the additional arrangement of the lubricating mechanism with the structure, the product realizes compound type lubrication of pressure and splash inside a rocker-arm chamber and guarantees that friction pairs of all parts can obtain uniformity, controllability and good lubrication in high-speed running, thus improving the reliability of parts in running and prolonging the service lives.
Description
Technical field
The utility model belongs to vertical type single-cylinder diesel engine, is specifically related to a kind of lever lubricating structure of vertical type single-cylinder diesel engine.
Background technique
At present, vertical type single-cylinder diesel engine on the market, friction pair between its valve rocker and the pitman arm shaft is a rolling friction pair, the lubricated main mode that combines with oil mist lubrication by grease lubrication of this rolling friction pair realizes, be embodied in: a plurality of little needle rollers that scribble lubricating grease are contained in the axis hole of valve rocker equably, valve rocker cooperates installation with pitman arm shaft after, little needle roller is clipped in the centre of valve rocker and pitman arm shaft as needle bearing, thereby realizes valve rocker and pitman arm shaft rolling friction; The lubricant mist that lubricant mist in the rolling friction pair has then splashed from the gear chamber inner chamber, mist of oil penetrates in the rolling friction pair from the oil inlet hole on the valve rocker, realizes that mist of oil is cunning.But, the shortcoming of its existence is: the rolling friction pair initial stage is lubricated by grease lubrication, along with after the lubricating grease on the needle roller runs off gradually, main by oil mist lubrication, but oil mist lubrication forms the harmony and the poor controllability of oil film on the friction pair between valve rocker and the pitman arm shaft, and this has restricted diesel engine on the one hand toward higher rotary speed direction development; On the other hand, it is more to assemble required part, be not easy to install and structure not compact.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, compact, lubricated harmonious good and reliability is high, the lever lubricating structure of the vertical type single-cylinder diesel engine of long service life.
Goal of the invention of the present utility model is achieved in that a kind of lever lubricating structure of vertical type single-cylinder diesel engine, comprise valve rocker, pitman arm shaft and rocker arm bracket, described valve rocker is supported on the two ends of pitman arm shaft; pitman arm shaft is fixed on the rocker arm bracket; wherein, and valve rocker is provided with the draining hole, it is characterized in that: be provided with associated axle sleeve in the endoporus of described valve rocker; axle sleeve is provided with and the corresponding drain tap in draining hole, and the draining hole on drain tap and the valve rocker is docked and connected.
Described axle sleeve and pitman arm shaft are the gap installation that matches.
Respectively be provided with an oil outlet that is communicated with the gap on the end face at the two ends of described pitman arm shaft.
Oil outlet on the described pitman arm shaft with the draining hole, drain tap is corresponding communicates.
The bottom surface at described pitman arm shaft middle part is provided with oil inlet hole.
The oil duct that is provided with on oil inlet hole on the described pitman arm shaft and the rocker arm bracket is docked and connected.
Described pitman arm shaft is a hollow tubular, and its two ends are provided with obstruction, thereby forms shoe cream room.
The utility model is compared the lubricating structure of the vertical type single-cylinder diesel engine of prior art, the advantage that has is: by the lubricating structure of this structure, make the combined type that has realized pressure in the rocker arm chamber and splashed lubricated, the part friction pair that has fully guaranteed distribution devices such as valve rocker, axle sleeve and pitman arm shaft, valve can obtain down harmony, controllability, good lubricated running up, thereby improved the reliability that part is in operation and increase the service life.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment;
Fig. 2 is the A-A sectional structure chart of the utility model Fig. 1;
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to Fig. 1 and shown in Figure 2, the lever lubricating structure of vertical type single-cylinder diesel engine of the present utility model is made up of valve rocker 1, pitman arm shaft 2, axle sleeve 5 and rocker arm bracket 3.Wherein, valve rocker 1 is supported on the two ends of pitman arm shaft 2, and pitman arm shaft 2 is fixed on the rocker arm bracket 3 by fastening piece, and 5 on axle sleeve is installed in the endoporus of valve rocker 1.This valve rocker 1 is provided with draining hole 4, and axle sleeve 5 be provided with valve rocker 1 on draining hole 4 corresponding drain taps 6, drain tap 6 is logical in succession with draining hole 4.Described axle sleeve 5 and pitman arm shaft 2 cooperate installation for gap 7, and valve rocker 1 can freely be rotated, and lubricant oil can be entered in the gap 7, thus the formation lubricant film.This pitman arm shaft 2 is a hollow tubular, and its two ends are provided with stops up 11, thereby forms shoe cream room 12.And, respectively be provided with an oil outlet 8 on the end face at the two ends of pitman arm shaft 2, this oil outlet 8 respectively with the drain tap 6 of shoe cream room 12, axle sleeve 5, draining hole 4 corresponding communicating on the valve rocker 1.Simultaneously, the bottom surface at the middle part of pitman arm shaft 2 is provided with oil inlet hole 9, and oil duct 10 butt joints that are provided with on this oil inlet hole 9 and the rocker arm bracket 3 communicate.In diesel engine when work,, lubricant oil enters shoe cream room 12 from the oil duct 10 of rocker arm bracket 3, oil inlet hole 9 under pressure successively.Wherein, the lubricant oil shunting of a part enters 7 li in the gap of axle sleeve 5 and pitman arm shaft 2, forms film lubrication axle sleeve 5 and pitman arm shaft 2; The lubricant oil of another part flows out through oil outlet 8, draining hole 4, drain tap 6, flows on the top and gas bar of valve 14 along the surface 13 of valve rocker 1, forms the valve guide bushing that oil film lubricates valve 14 and cooperation thereof.The lever lubricating structure of this vertical diesel engine, overcome outside the existing single splash lubrication mode, also designs of part such as rocker arm bracket 3, pitman arm shaft 2, valve rocker 1 are brought brand-new variation, it shows as: rocker arm bracket 3 can change the supporting of single shaft symmetry into by the asymmetric supporting of twin shaft, make the volume-diminished of valve rocker 1, cause the reduction movement inertia, help further improving the rotating speed of vertical diesel engine, can realize that existing vertical type single-cylinder diesel engine is not higher than 2400 rev/mins from rated engine speed, be 2600 rev/mins to 3200 rev/mins rotating speed designs to rated engine speed.Therefore, the lever lubricating structure of vertical type single-cylinder diesel engine of the present utility model, it can guarantee fully that part friction pair of valve rocker 1, axle sleeve 5 and distribution devices such as pitman arm shaft 2, valve 14 can obtain under 2600 to 3200 rev/mins running up reliable, good lubricated, the stability of raising part, reliability with and working life.
