Abstract
The utility model relates to a four-cylinder engine double-shaft balancer, comprising a casing, a balancing shaft, a balancing block and a gear drive device. The utility model is characterized in that the bearing of the balancer is a sliding bearing with a special-purpose fluid oil channel. The four-cylinder engine balancer of the utility model achieves the goal of reducing cost, simple process, the convenience of users for the use of the sliding bearing, and at the same time the fluid oil channel thereon can ensure the substantial and effective work of the sliding bearing.
Description
Technical field: the utility model belongs to engine art, relates to a kind of double-shaft balance device of four cylinder engine.
Background technique: four cylinder engine second-order inertia force unbalance, engine luggine are relatively more severe.This is a geneogenous problem in motivation design, the manufacturing, in order to overcome this problem, begin to develop this second-order inertia equilibrium of forces mechanism, present most of limousine all has been equipped with this four cylinder second-order inertia equilibrium of forces mechanisms, and the four-cylinder diffusion that progressively turns to minibus, Light-duty Vehicle, intermediate-size car, truck etc. to use.Now big, the complex structure of the four cylinder second-order inertia equilibrium of forces agency costs developed of Cummins Corp, assembling difficulty, counterbalance effect is also poor.
Summary of the invention: existing this type of balanced controls cost is big in order to solve for the utility model, complex structure, assembling difficulty, the not good problem of counterbalance effect, a kind of double-shaft balance device of four cylinder engine is proposed, comprise housing, trunnion shaft, equilibrium block and gear drive, it is characterized in that: the bearing of described balace weight is a sliding bearing, and has the special lube road.The utility model four cylinder engine balace weight reduces cost, simplifies technology, user friendly purpose owing to adopt sliding bearing to reach; The lubricating oil path that has simultaneously can guarantee that sliding bearing works fully effectively.
Description of drawings: Fig. 1 is the structural representation of the double-shaft balance device of the utility model four cylinder engine;
Fig. 2 is the special-purpose oil duct of the double-shaft balance device of the utility model four cylinder engine;
Fig. 3 is that the oil pipe lubricating structure is drawn in special-purpose spray bar of the double-shaft balance device of the utility model four cylinder engine and pressure-limit valve overflow.
Embodiment: the double-shaft balance device of the utility model four cylinder engine mainly is the lubrication problem that solves motor double-shaft balance device.What american commings adopted is needle bearing, not high to lubricating requirement, only needs just much of that with splash lubrication.But, needle bearing cost height, the structure and the manufacture cost of correlated parts all increase substantially.Adopt sliding bearing can reduce cost, simplify technology, make things convenient for the user, but sliding bearing needs effective lubricant method to the lubricating requirement height, could guarantee that sliding bearing works effectively.
As shown in Figure 1, 2, the double-shaft balance device of this four cylinder engine comprises housing 1, trunnion shaft 2, equilibrium block 3 and gear drive 4, and balance shaft bearing 5 is a sliding bearing, special lube road 6.Wherein oil leab 6 comprises two kinds of structures.A kind of lubricating oil path is to have by oil leab structure a plurality of part combinations, that have multiple asphalt channel to link to each other, is by custom-designed special-purpose oil duct on a plurality of parts, oil pump, and the pressure oil that pumps, guiding comes to lubricate the bearing of double-shaft balance device.As shown in Figure 2, constitute by several perpendicular inclined hole oil ducts 11 on horizontal oil duct 9 that reaches hole 7 corresponding on the housing 1, hole 8, housing 1 bottom on the main bearing cap that is arranged on motor and the partition wall 10.
Now be that example illustrates: on the main bearing cap of motor, punch 7 with Fig. 2, the lubricant oil of main bearing is extracted, in position punching 8 corresponding on the double-shaft balance device housing 1 with hole 7 on the main bearing cap, lubricant oil is guided to lubricating bearings in the bearing 5 of double-shaft balance device, the purpose that the pressure oil of realizing pumping with oil pump lubricates the bearing of double-shaft balance device.Simultaneously, the adjacent bearing that punches again draws oil and goes to lubricate.The rear bearings of double-shaft balance device, adopt use the same method lubricated.The intermediate bearing of double-shaft balance device adopts and designs horizontal oil duct 9 in the bottom of double-shaft balance device housing 1, beats several perpendicular inclined holes 11 again on front wall and middle wall, and oil is drawn lubricated in the past two middle bearings.When reality is used, bore the part of asphalt channel, not necessarily above those parts, also can be some other part.
Second kind of structure of oil leab 6 as shown in Figure 3, bearing 5 is that the overflow after utilizing the special-purpose spray bar 12 be installed in the straight-through main oil gallery in motor middle part and being positioned at pressure-limit valve is drawn oil pipe 13 and drawn oil and come lubricated.Specifically be by spray bar 12 oil to be sprayed to bearing 5 filler openings after special-purpose oil duct by motor attracts lubricant oil, the lubricant oil that while is come out bypass after the pressure limiting of engine oil pressure limiting valve, guide bearing 5 filler openings into drainage tube 13, by oil leab machine oil being driven into needs lubricated position again.
Claims (3)
1, a kind of double-shaft balance device of four cylinder engine comprises housing, trunnion shaft, equilibrium block and gear drive, it is characterized in that: the bearing of described balace weight is a sliding bearing, and has the special lube road.
2, the double-shaft balance device of four cylinder engine as claimed in claim 1 is characterized in that: described oil leab is to be made of several perpendicular inclined holes on the horizontal oil duct of the hole that is arranged on the correspondence on main bearing of engine lid and the described housing, described lower housing portion and the partition wall.
3, the double-shaft balance device of four cylinder engine as claimed in claim 1 is characterized in that: described oil leab by the special-purpose spray bar that is installed in the straight-through main oil gallery in motor middle part and the overflow after being positioned at pressure-limit valve draw oil pipe and form.
