Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of crankshaft thrust piece, especially to an engine crankshaft thrust piece with self-lubricating structure. BACKGROUND

[0002] With the continuous development of the automobile industry and the machinery industry, the performance requirements of engines are becoming higher and higher. Modern engines need to output more power in smaller volume and weight to meet people's demand for high efficiency of transportation tools and mechanical equipment. In the background of global energy crisis and environmental problems becoming increasingly serious, governments of various countries have formulated strict regulations on fuel consumption and exhaust emission of engines. Engine manufacturers are under great pressure and need to continuously improve engine technology to reduce fuel consumption and harmful gas emission. This promotes the design and operation of engines to be more refined, and higher requirements are put forward for the performance of each part. The crankshaft thrust piece is an important wear-resistant part in the engine, and its performance improvement has an important influence on the energy saving and environmental protection performance of the whole engine. The lubrication of the traditional thrust piece mainly relies on the lubricating oil film. However, under some special working conditions, such as engine starting and stopping instant, high temperature and high pressure environment or inappropriate lubricating oil viscosity, the lubricating oil film may be difficult to form or unstable. This makes the thrust piece in a boundary lubrication or dry friction state in a short period of time, causing serious wear. In addition, factors such as the quality of lubricating oil and the stability of the supply system also affect the lubrication effect of the thrust piece, reducing the reliability and stability of the engine. The engine crankshaft thrust piece with self-lubricating structure is produced under the joint action of the continuous development of engine technology, the limitations of traditional thrust piece, the progress of material science and lubrication technology, and the application experience enlightenment in related fields.

[0003] In the prior art, the crankshaft thrust piece of the engine is mainly used to limit the axial movement of the crankshaft to prevent the crankshaft from deviating due to excessive axial force and ensure the normal operation of the engine. However, the traditional crankshaft thrust piece has large friction with the internal parts of the engine during operation, which is prone to wear. Moreover, due to the harsh working environment, the thrust piece may be damaged prematurely due to insufficient lubrication. Therefore, we propose an engine crankshaft thrust piece with self-lubricating structure to solve this problem. UTILITY MODEL CONTENTS
