Thrust plate forced lubricating structure

Abstract

The invention discloses a thrust plate forced lubricating structure. The thrust plate forced lubricating structure comprises a main shaft bushing, thrust plates, and a main bearing cap, wherein the inner circumferential face of the main shaft bushing is provided with an oil storage groove in the circumferential direction and provided with an oil inlet hole communicating with the oil storage groove; the thrust plates are arranged on the end faces of the two sides the main shaft bushing in pair; the upper portion of the main shaft bushing is tightly pressed by the main bearing cap, and the main bearing cap is fixed to a machine body by penetrating a bolt through a main bearing cap bolt hole, and the main bearing cap bolt hole communicates with the oil storage groove of the main shaft bushing; and the main bearing cap is provided with thrust plate lubricating oil channels, inlets of the thrust plate lubricating oil channels communicate with the main bearing cap bolt hole, and outlets of the thrust plate lubricating oil channels are formed in the outer sides of the thrust plates. The lubricating condition between the thrust plates and a crankshaft is improved through the thrust plate forced lubricating structure, lubrication can still be ensured after long-time thrust suffering, the failure rate of the thrust plates is lowered, and the reliability of a complete machine is improved.

Description

technical field [0001] The invention relates to the field of engine lubrication, in particular to a thrust plate forced lubrication structure. Background technique [0002] In the existing engine, the friction pair of the thrust plate and the crankshaft is mainly lubricated by splash lubrication, but with the development of supporting technology of the engine, the contact working time between the thrust plate and the crankshaft is getting longer and longer, and the force is getting stronger. If it gets bigger and bigger, this will lead to the destruction of the oil film between the thrust plate and the crankshaft, resulting in abnormal wear and even failure of the thrust plate. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those ...
