Problems solved by technology

Since the piston reciprocates at high speed in the cylinder and bears the power of oil and gas explosion, if the piston is not lubricated enough, the small end of the connecting rod will be locked with the piston pin, resulting in an accident

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0009] Such as figure 1 As shown, a piston connecting rod 3 includes a body 31; the two ends of the body 1 are respectively provided with a large end 32 and a small end 33; the large end 32 is provided with a large end shaft hole 321; the small end 33 is provided with a small end shaft hole 331 The top of the small end 33 is provided with two vertical small end oil inlet holes 332; the small end shaft hole 331 is provided with a copper sleeve 4; the copper sleeve 4 is provided with a copper sleeve oil inlet corresponding to the small end oil inlet hole 332 Hole 41.

[0010] Due to the arrangement of the copper sleeve 4, the better oiliness of the copper sleeve 4 can be utilized to increase the lubricating effect. Simultaneously, lubricating oil can reach the effect of increasing lubricating performance through the joint of small end oil inlet hole 332 and c...

Abstract

The invention discloses a piston rod. The piston rod comprises a body (31), wherein two ends of the body (1) are a large end (32) and a small end (33) respectively; a large end shaft hole (321) is formed in the large end (32); a small end shaft hole (331) is formed in the small end (33); two small end oil inlet holes (332) which are perpendicular to each other are formed in the top of the small end (33); a copper bush (4) is arranged in the small end shaft hole (331); and copper bush oil inlet holes (41) which correspond to the small end oil inlet holes (332) are formed in the copper bush (4). The piston rod and a piston pin can be lubricated effectively, so that working reliability of an engine is improved.

Description

technical field [0001] The invention relates to a piston connecting rod. Background technique [0002] The lubrication between the piston connecting rod and the piston pin usually uses an oil pump to supply oil to the large end of the piston connecting rod, and then is thrown out by the centrifugal force of the crankshaft rotation, so that the oil enters the joint between the small end of the piston connecting rod and the piston pin. Because the piston reciprocates at a high speed in the cylinder and bears the power of oil and gas explosion, if the piston is not lubricated enough, the small end of the connecting rod will lock with the piston pin, resulting in an accident. [0003] Therefore those skilled in the art devote themselves to developing a kind of piston connecting rod that makes the small end of the connecting rod and the piston pin lubricate. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the technical problem to be ...
