Abstract
The utility model relates to a bearing used for a four-cylinder engine double-shaft balancer, which is characterized in that the bearing is a sliding bearing, the bearing sleeve is provided with an oil-guiding groove, an oil hole and an oil channel arranged along the circumference, wherein the oil hole is communicated with the oil channel which is communicated with the oil-guiding groove. The use of the structure of the bearing and the oil channel makes the oil inlet hole have the oil outlet function and impurity outlet function at the same time, thereby improving the recirculation and metabolism of fluid oil, and prolonging the life time of the fluid oil and the bearing.
Description
Technical field: the utility model belongs to engine art, relates to a kind of bearing that is used for four cylinder engine double-shaft balance device.
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.In this four cylinders second-order inertia equilibrium of forces mechanism, the fuel-displaced problem of slagging tap of bearing will have influence on the work of bearing.
Summary of the invention: the utility model is for the fuel-displaced problem of slagging tap of the bearing that solves this type of balace weight, a kind of bearing that is used for the four cylinder engine balace weight is proposed, it is characterized in that: described bearing is a sliding bearing, bearing housing is provided with oil guide slot, oilhole and along the oil duct of circumference, described oilhole communicates with oil duct, and described oil duct communicates with oil guide slot.Owing to adopt the bearing of this structure and oil duct to make oil inlet hole have fuel-displaced simultaneously and go out the function of impurity, strengthened the circulation and the metabolism of lubricant oil, the life-span of having improved lubricant oil and bearing.
Description of drawings: Fig. 1 is the structural representation that is used for the bearing of four cylinder engine double-shaft balance device of the present utility model;
Fig. 2 is the oil duct schematic representation that is used for the bearing embodiment one of four cylinder engine double-shaft balance device of the present utility model;
Fig. 3 is the oil duct schematic representation that is used for the bearing embodiment two of four cylinder engine double-shaft balance device of the present utility model.
Embodiment: this bearing 1 that is used for four cylinder engine double-shaft balance device is sliding bearing, bearing housing 2 is provided with oil guide slot 3, oilhole 4 and along the oil duct 5 of circumference, oilhole 4 communicates with oil duct 5, oil duct 5 communicates with oil guide slot 3: wherein oilhole 4 can be on oil duct 5, also can be on the next door of oil duct 5, be communicated with by little oil groove.As shown in Figure 2, the center oilhole 41 of bearing 1 is positioned on the central oil passage of along the circumferential direction arranging 51, and oil guide slot 3 communicates with oil duct 5, after lubricant oil enters central oil passage 51, flows out bearing by center oilhole 41 again, and impurity is also discharged through center oilhole 41 simultaneously.Fuel-displaced in order to improve, go out the impurity performance, the side that oil duct 5 can be arranged in bearing housing 2 is a side oil channel 52, be not arranged in the central position, as shown in Figure 3, oilhole 42 is positioned at the sidepiece of bearing housing 2, and formed pressure reduction because oil guide slot 3 distances on oil duct 52 both sides are different this moment, be beneficial to the unimpeded of oil circuit, be convenient to lubricant oil and impurity and from oilhole 42, discharge.
The bearing oil of this moment has two kinds of functions: fuel-displaced and oil-feed.Specifically the time be in the sort of state, will see rotating speed and oily state on every side and decide in work.No matter be the sort of state, always to the best state of bearing.Promptly when rotating speed low, automatically the amount of oil-feed after a little while, oil enters bearing just from top through oil-through hole, lubricate guarantees lubricating of bearing.When the rotating speed height, the amount of oil-feed is many automatically, and when oil pressure was also high, oil spilt out through oil-through hole just from following, plays a metabolic effect, also fricative heat was led out simultaneously; Otherwise lubricant oil is not metabolic, and oily temperature rise De Taigao can reduce life-span of lubricant oil, and lubricating oil viscosity descends, and reduces lubrication effect, and lubricant oil also can coking, rotten, aging.
Oil discharge passage and go out booty, the impurity passage is substantially the same.Oil is light, and booty, impurity weigh, so oil is in recurrent state always; And booty, impurity is metal impurities particularly, just may accumulate in oil duct or oilhole outer.
