Abstract
The utility model relates to a lubricating device of an engine. A piston connecting rod component is arranged into an engine body; a crank shaft is supported in the engine body; the engine body is connected with a cylinder sleeve in a matching manner; a crank shaft box cover is arranged on the engine body; an oil pump is arranged in the crank shaft box cover; and an oil filter and an oil feeding guide pipe are arranged on the crank shaft box cover. The lubricating device is characterized in that: an oil storage passage is formed on the engine body; a bearing bush is matched with the engine body; an oil hole is formed on the bearing bush; and an oil storage cavity is formed by a screw plug locked at the head of the oil storage passage and the oil hole. The oil hole is aligned with the oil storage passage. The lubricating device saves a rolling bearing, reduces the cost of the engine, effectively lubricates the crank shaft and the bearing bush, enhances the reliability of the engine, can lubricate the part between the crank shaft and the bearing bush without importing an oil path from a high pressure conveying oil path of the oil pump, and can simplify a lubricating structure of the engine.
Description
Technical field
The utility model relates to a kind of lubricating fitting of motor, specifically belongs to the engine lubrication technical field.
Background technique
Body rotates in order to support bent axle in the former motor, tends between body and bent axle rolling bearing is set, and carries out lubricating rolling bearing and bent axle by the mode of splash lubrication then.But in order to reduce cost and to simplify engine structure, cancel the rolling bearing on the conventional engines and used the rotation that bearing shell supports bent axle instead, carried lubricant oil to carry out part lubricated between bent axle and the bearing shell by oil pump to the oil circuit of bent axle setting then.
Such lubricating system, in the firm entry into service of motor, lubricant oil needs could to arrive for a long time part between bent axle opposite side and the bearing shell and carries out lubricated to it, causes the damage to motor easily.So, in the past for lubricated bent axle and bearing shell part, tend to adopt and from the high-pressure delivery oil circuit of oil pump, draw an oil circuit again and lubricate bearing shell and bent axle, like this, will cause oil channel structures to become very complicated, also make engine structure become complicated simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of and can omit rolling bearing, and do not need from the high-pressure delivery oil circuit of oil pump, to draw in addition oil circuit and lubricate part between bent axle and the bearing shell and just can carry out lubricating fitting the motor between bent axle and the bearing shell.
The technological scheme that provides according to the utility model, the lubricating fitting of motor comprises crankcase cover, oil pump, oil filter, engine body, the oil-feed conduit, bearing shell, bent axle, cylinder sleeve, piston rod part, piston rod part are vertically mounted in the engine body, and described crankshaft support is in engine body, engine body and cylinder sleeve are connected, crankcase cover is installed on the engine body, and oil pump is installed in the crankcase cover, and oil filter and oil-feed conduit are installed on the crankcase cover, feature is: described engine body is provided with the oil storage road, bearing shell is a tight fit on the engine body, and described bearing shell is provided with oilhole, and plug screw is locked in oil storage road head and oilhole forms a shoe cream room.Described oilhole is aimed at the oil storage road.
Be respectively arranged with first oil leab, second oil leab, the 3rd oil leab on the described crankcase cover.Described bent axle is provided with the 4th oil leab.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Omit rolling bearing, reduced the cost of motor; Can effective lubricating bent axle and bearing shell, improved the reliability of motor; Can simply be arranged on the body, make engine structure become simple; Do not need from the high-pressure delivery oil circuit of oil pump, to draw in addition the part that oil circuit lubricate between bent axle and the bearing shell and just can carry out to simplify lubricating structure of engine, saved cost yet lubricating between bent axle and the bearing shell.

Embodiment
As Fig. 2～shown in Figure 4, comprise the crankcase cover 1(first oil leab 1a, the second oil leab 1b, the 3rd oil leab 1c), oil pump 2, oil filter 3, engine body 4(oil storage road 4a), oil-feed conduit 5, bearing shell 6(oilhole 6a), bent axle 7(the 4th oil leab 7a), oil sealing 8, cylinder sleeve 9, piston rod part 10 and plug screw 11 etc.
The utility model piston rod part 10 is vertically mounted in the engine body 4, and described bent axle 7 is provided with oil sealing 8 and is bearing in the engine body 4, and described bent axle 7 is provided with the 4th oil leab 7a.Engine body 4 is connected with cylinder sleeve 9, and crankcase cover 1 is installed on the engine body 4, and oil pump 2 is installed in the crankcase cover 1, and oil filter 3 is installed on the crankcase cover 1 with oil-feed conduit 5.Be respectively arranged with the first oil leab 1a, the second oil leab 1b, the 3rd oil leab 1c on the described crankcase cover 1.Described engine body 4 is provided with oil storage road 4a, and bearing shell 6 is a tight fit on the engine body 4, and described bearing shell 6 is provided with oilhole 6a, and plug screw 11 is locked in oil storage road 4a head and oilhole 6a forms a shoe cream room.Described oilhole 6a aims at oil storage road 4a.
As shown in Figure 4, before engine start, open plug screw 11, add lubricant oil to oil storage road 4a, lock plug screw 11 then, make lubricant oil be full of the oilhole 6a of oil storage road 4a and bearing shell 6, so just formed a simple lubricating fitting, such lubricating fitting simply is arranged on the body, makes engine structure become simple.
In Fig. 2～Fig. 4, when engine start, oil pump 2 begins to rotate, drive lubricant oil and enter the first oil leab 1a via oil-feed conduit 5, after oil filter 3 filterings, enter the second oil leab 1b again, under the effect of oil pump 2, lubricant oil begins to form extreme pressure lubricant and is pressed into the 3rd high-tension lubrication oil duct 1c through oil pump 2, and lubricant oil begins bearing shell on the crankcase cover 16 and bent axle 7 contacting parts are lubricated then.After having lubricated, lubricant oil enters the 5th oil leab 7a in the bent axle 7 and arrives the piston rod and the contacting part of bent axle and the contacting part of engine body 4 top bearing shells 6 and bent axle 7 and be lubricated.
After engine start, because the bearing shell 6 from oil-feed conduit 5 to engine body on 4 is relative longer with the oil duct of bent axle 7 contacting parts, lubricant oil needs a period of time to arrive this part is lubricated, before extreme pressure lubricant does not have arrival, lubricant oil among the oil storage road 4a just begins to carry out lubricating this part via the oilhole 6a on the bearing shell 6, after extreme pressure lubricant arrives, under the effect of pressure, begin then to carry out oil storage road 4a is supplied lubricant oil, make motor after starting next time, oil storage road 4a also has sufficient lubricating oil to carry out engine lubrication, motor from start to finish can obtain effective lubricating like this, can well improve the reliability of motor like this.
