Embodiment Construction

[0009] The present invention will be further described in conjunction with the accompanying drawings.

[0010] As shown in Fig. 1, Fig. 1 is a schematic structural diagram of a crank bush and a connecting rod bush without lubricating oil passages on the inner surface, and the inner surface 1 is a smooth arc without lubricating oil passages.

[0011] As shown in Figure 2, the crankshaft and connecting rod bushes of the present invention are provided with several lubricating oil channel grooves 2 on the inner surface 1 in contact with the crankshaft, which reduces the frictional contact surface, increases the oil contact surface, and reduces At the same time, with the operation of the internal combustion engine, the oil pump pumps the lubricating oil to the lubricating surfaces, and the oil passage grooves on the inner surfaces of the crankshaft and connecting rod bushes are also filled with lubricating oil. The lubrication between the connecting rod bush and the crankshaft is m...

Abstract

The invention relates to a crank bush and connecting rod bush of internal combustion engine, wherein the invention is characterized in that: the inner surfaces of crank bush and connecting rod bush that contacted with the crank have lubricant grooves, to reduce the friction contact area, and the groove contains oil to realize better lubricant effect, reduce the friction factor, improve the power of engine and reduce the energy consumption.

Description

Technical field: [0001] The invention relates to an internal combustion engine assembly, in particular to a crankshaft bush and a connecting rod bush of an internal combustion engine. Background technique: [0002] When the internal combustion engine is working, there is friction between the crankshaft bush, the connecting rod bush and the crankshaft, and the friction coefficient directly affects the power and energy loss of the internal combustion engine. In the current internal combustion engine, the contact surfaces of the crankshaft bush, the connecting rod bush and the crankshaft are smooth arc surfaces, the friction surface is large, and the friction coefficient is relatively large, which affects the power and fuel consumption of the internal combustion engine. Invention content: [0003] The object of the present invention is to provide a crank bush and connecting rod bush with small contact surface with the crankshaft and good lubricating effect. [0004] The tech...
