Specific implementation mode
1-4 below in conjunction with the accompanying drawings is clearly fully described by technical scheme of the present invention.
Embodiment 1：With reference to figure 1-4.A kind of gear lubrication system of diesel engine, be applied to single cylinder diesel, including bent axle 1,
Crankshaft timing gear 2, gear chamber are located at 6 one end of output shaft of bent axle 1, are fixed on the output shaft 6 and transfer power to tooth
The crankshaft timing gear 2 of engineer room middle gear power train supports and opens up the offer of oriented bent axle 1 in the main beating cap 9 of bent axle input terminal
The input oil duct 11 of pressure lubrication oil, 6 inside axial direction of the output shaft offer axial output oil duct 5, are also opened on bent axle
Equipped with the first oblique oil duct 10, the second oblique oil duct 7 and accumulator 8, the first oblique oil duct 10 is respectively communicated with input oil duct 11
With accumulator 8, the second oblique oil duct 7 is respectively communicated with accumulator 8 and axial output oil duct 5, radial in the crankshaft timing gear 2
On offer perforation a diameter of φ 1mm gear nozzle opening 3, be further opened with radial direction in 6 inner radial direction of the output shaft
Oil duct 4 is exported, one end of the radial output oil duct 4 is connected with the axial output oil duct 5；The other end is sprayed with the gear
Oilhole 3 is connected.
When diesel engine works, lubricating oil enters input oil duct 11 under the pumping effect of lubricating oil pump, by body main oil gallery,
Pass through the first oblique oil duct 10, accumulator 8, the second oblique oil duct 7, axial output oil duct 5, radial output oil duct 4 successively, enters
Gear nozzle opening 3, under the oil pressure of lubricating oil pump elevated pressures, lubricating oil is in that oily line is spouting from the gear nozzle opening 3, with
The rotation of bent axle 1, spouting lubricating oil is ejected into the other teeth of pinion unit along gear direction of rotation, successively forward direction
The flank of tooth of wheel, and when crankshaft timing gear 2 is rotated to gear nozzle opening 3 towards gear chamber cover inner surface, lubricating oil beam is also
It can be sprung back to from gear chamber cover inner surface on the gear of lower section, to realize that the good lubrication to pinion unit acts on.
Embodiment 2：With reference to figure 1-4.A kind of gear lubrication system of diesel engine is applied to single cylinder diesel, structure and work
Make mode and embodiment 1 is almost the same, difference lies in a diameter of φ for radially offering perforation in the crankshaft timing gear 2
The gear nozzle opening 3 of 1.5mm.
The gear lubrication system of diesel engine of above-described embodiment 1,2 is cooperated with output shaft 6, crankshaft timing gear 2 and is installed
Keyway on the basis of, radial output oil duct 4 and gear nozzle opening 3 are process using equal angular design, therefore just by bent axle
When gear 2 be mounted on output shaft 6 after, the radial output oil duct 4 is mutually just being connected to relatively with the gear nozzle opening 3.Meanwhile
Because crankshaft timing gear 2 is interference fit with output shaft 6, it ensure that lubricating oil in the radial output oil duct 4 by output shaft 6
Oil circuit sealing effect between the gear nozzle opening 3 of crankshaft timing gear 2.
It is well known that being further sleeved with connecting rod bearing shell on the rod journal of crankshaft of diesel engine, original lubricating oil on bent axle is utilized
The force feed between rod journal and connecting rod bearing shell is realized in road, and when diesel engine peak torque operating mode, connecting rod bearing shell stress is most
Greatly, too low engine oil pressure can cause the problems such as connecting rod bearing shell high temperature or even bearing shell peeling, change watt.As previously mentioned, bavin of the present invention
Oil machine gear lubrication system, be on the basis of bent axle original lubricant passage way, add the second oblique oil duct 7, axial output oil duct 5,
Radial output oil duct 4, gear nozzle opening 3, form gear lubrication oil duct, reduce the engine oil pressure of former lubricant passage way.
In the prior art, to its oil flow rate, engine oil pressure, there are enough surpluses, machine oil when diesel engine oil pump designs
When pump normal work, oil flow rate, oil pressure force value reach far away design limit.Oil pump of single cylinder diesel engine in the prior art
Technology requirement " at 70 DEG C of oil temperature, when output pressure is 350 kPa, oil pump capacity is not less than 7L/1000rpm ", by adjusting
Lubricating oil pump pressure regulator valve carries out lubricating oil pump bulge test test, 70 DEG C of oil temperature, the oil flow rate 7L/1000rpm the case where
Under, lubricating oil pump surveys output pressure highest can be to 450 kPa.
To solve the problems, such as the reduction of lubricant passage way engine oil pressure, applicant is by adjusting lubricating oil pump pressure regulator valve, by lubricating oil pump
Operating pressure is improved to 400 kPa, respectively to having carried out machine oil using 6 diesel engines of gear lubrication system of diesel engine of the present invention
Pressure measurement, experimental data are shown in Tables 1 and 2.
Table 1：φ 1.5mm gear nozzle opening engine oil pressure test datas
2 φ 1mm gear nozzle opening engine oil pressure test datas of table.
By 1 table of table, 2 data it is found that engine oil pressure test result ranging from 200-300 kPa, it is normal to meet diesel engine
To the requirement of engine oil pressure when work, that is, the diesel engine of gear lubrication system of diesel engine of the present invention is used, engine oil pressure can
Meet and uses needs.
Above-mentioned given embodiment 1,2, advantageous effect having the same are：Pass through the radial direction of the output shaft in bent axle
Direction offers the radial output oil duct being connected with axial output oil duct, while in the bent axle with output shaft interference fit installation
The gear nozzle opening for radially offering perforation of timing gears corresponding position need not be reconnected in the end face of output shaft and be carried
The atomizer of spray orifice reduces number of parts, and with the rotation of bent axle and its operating of drive pinion unit, lubricating oil
It is spouting from the gear nozzle opening on the crankshaft timing gear flank of tooth, it can recycle and positively spray to the other teeth of pinion unit
The flank of tooth of wheel realizes the lubrication to pinion unit.Solve that prior art lubricating oil is arranged from crankshaft end-face with spray
The atomizer in hole is sprayed with dynamic umbrella, it cannot be guaranteed that lubricating oil can be directly injected to the flank of tooth of pinion unit proximal end gear
The upper problem that can be directly injected to again on the flank of tooth of distal end gear, the effectively lubricating to preferably solve pinion unit are asked
Topic.
The present invention on the output shaft of bent axle by being arranged radial output oil duct, being opened up in crankshaft timing gear corresponding position
Gear nozzle opening, reduces the quantity of prior art part, and realizes the best lubricant effect of pinion unit.
In addition, single cylinder diesel is often provided with mechanical governing system in crankshaft output end, including flies block, flies block and tune
The parts such as fast axis are used for mechanical speed governors, therefore do not have position that the atomizer with spray orifice is arranged again on crank shaft output shaft end face,
And the present invention need not arrange the atomizer with spray orifice, efficiently solve by the way that radial output oil duct and gear nozzle opening is arranged
The problem.
