Abstract

The invention discloses a four-cylinder crankshaft of a diesel engine that prevents shaking, and belongs to the field of diesel engines. A four-cylinder crankshaft of a diesel engine that prevents shaking includes a crankshaft body, which includes a main shaft, and the main shaft is fixedly connected with a plurality of eccentrically arranged crankshafts. The connecting rod shaft can cooperate with the main shaft half sleeve, the anti-shake lubrication assembly and the crankshaft body, so that the anti-shake buffer arc can buffer the vibration generated by the crankshaft body during the transmission process. Multiple anti-shake lubrication assemblies and the connecting rod The shaft interval is set. In the case of long stroke and large cylinder diameter, the anti-shake buffer arc effectively stabilizes the crankshaft body, improves the transmission accuracy of the crankshaft body, reduces the occurrence of cylinder motion stuttering, and improves the working efficiency of the diesel engine. Ensure the service life of the crankshaft body, and change the surface contact to electrical contact through the anti-friction steel ball to reduce friction, effectively improve the energy conversion rate of the diesel engine, and improve the energy utilization rate.

Description

technical field

[0001] The invention relates to the field of diesel engines, more specifically, to a four-cylinder crankshaft of a diesel engine capable of preventing shaking. Background technique

[0002] A diesel engine is an internal combustion engine that uses diesel as fuel. The diesel engine is a compression ignition engine, and it is often called the Diesel engine after the main inventor Diesel. When the diesel engine is working, the air sucked into the cylinder of the diesel engine is compressed to a high degree due to the movement of the piston, reaching a high temperature of 500-700°C. Then the fuel is sprayed into the high-temperature air in the form of mist, and mixed with the high-temperature air to form a combustible mixture, which automatically ignites and burns. The energy released in the combustion acts on the top surface of the piston, pushing the piston and converting it into mechanical work of rotation through the connecting rod and crankshaft. [0003...
