Description

Bush for engine

Technical Field

The utility model belongs to the technical field of mechanical parts, a bush is related to, in particular to bush for engine.

Background

Automobile engine's energy conversion mainly relies on the cooperation transmission of piston and connecting rod, because the connecting rod need be the swing that does not stop at the during operation, consequently need add between connecting rod rotation end and piston pin and establish the bush and protect the connecting rod, adopt the lubricating oil that splashes to lubricate between most engine connecting rod bush and the piston pin, the continuous motion entering bush of lubricating oil through the connecting rod and the clearance between piston pin, but this present bush single structure, the unable high-efficient abundant entering bush of lubricating oil and piston pin between save the lubrication, lubricated effect is poor.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and make lubricating oil fully get into between bush and the piston pin, improve lubricated effect's bush for the engine.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a bush for engine, a serial communication port, includes the bush main part, bush main part middle part run through and seted up the shaft hole, the tip perisporium of bush main part radially has the oil conservation section and surrounds the section outward in proper order, surround the section buckling extended in oil conservation section periphery department, bush main part internal perisporium on seted up a plurality of oil storage tank along axial interval distribution, oil conservation serve circumference and seted up a plurality of oil feed tank, bush main part tip perisporium on seted up a plurality of inlet port, inlet port and the inside intercommunication of bush main part, the crossing setting of axis of inlet port and oil feed tank's axis, the oil inlet circular arc groove has been seted up on the bush main part tip inner wall.

In the above bushing for an engine, the oil inlet groove has an arc-shaped strip structure.

In the above bushing for an engine, the oil inlet groove has a circular hole structure.

In the above bushing for an engine, the oil inlet hole is obliquely formed and is obliquely arranged toward the oil storage tank.

In the above-described engine bushing, an oil buffer space is formed between the surrounding section, the bushing main body, and the oil retaining section.

In the above-mentioned bush for an engine, the oil retaining section is bent and extended obliquely.

Compared with the prior art, the lining for the engine has the advantages of sufficient lubrication and high-efficiency lubrication effect.

In the drawing, 1, a bush main body; 2. a shaft hole; 3. an oil retention section; 4. an enclosing section; 5. an oil storage tank; 6. an oil inlet groove; 7. an oil inlet hole; 8. an oil inlet arc groove; 9. an oil-buffering space.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, fig. 2, fig. 3, fig. 4 shows, this bush for engine, including bush main part 1, bush main part 1 middle part is run through and is seted up shaft hole 2 and supplies the piston pin to connect and join in marriage, bush main part 1's tip perisporium radially outward along having oil retaining section 3 and surrounding section 4 in proper order, surrounding section 4 is buckled and is extended in oil retaining section 3 periphery department, set up a plurality of oil storage tank 5 along axial interval distribution in bush main part 1 internal perisporium, a plurality of oil feed tank 6 has been seted up to oil retaining end upper circumference, a plurality of inlet port 7 has been seted up on the bush main part 1 tip perisporium, inlet port 7 and the inside intercommunication of bush main part 1, the axis of inlet port 7 intersects the setting with the axis of inlet port 6, oil inlet arc groove 8 has been seted up on the bush main part 1 tip inner wall.

The first scheme is as follows: as shown in fig. 3, the oil inlet tank 6 has an arc-shaped strip structure.

Scheme II: as shown in fig. 4, the oil inlet groove 6 has a circular hole structure.

Preferably, the oil inlet hole 7 is formed obliquely, and the oil inlet hole 7 is obliquely formed toward the oil sump 5.

Preferably, an oil buffer space 9 is formed among the surrounding section 4, the bushing main body 1 and the oil retaining section 3.

Preferably, the oil retaining section 3 is an inclined bending extension.

Lubricating oil splashes to by surrounding section 4 through inlet tank 6 and the interval department that surrounds between section 4 and the bush main part 1, the slow oily space 9 that forms of bush main part 1 and oil-retaining section 3, enter into in the bush main part 1 through inlet port 7 after, because inlet port 7 sets up for the slope, consequently, can play an incline and lead oily effect, additionally, lubricating oil still can follow in the income oil circular arc groove 8 gets into bush main part 1, enter into the lubricating oil in the bush main part 1 in lubricated, reach through a plurality of oil storage tanks 5 and slow oily, the purpose of oil storage, abundant lubricate, reach the lubricated effect of efficient.
