Problems solved by technology

Most of the existing four-cylinder crankshafts are in-line transmission. During the transmission process, due to the increase of stroke and cylinder diameter, the vibration of the four-cylinder crankshaft in the process of power transmission is also increasing, which reduces the transmission accuracy of the four-cylinder crankshaft. It is easy to cause the cylinder movement to be stuck, reduce work efficiency, and affect the service life of the four-cylinder crankshaft

Embodiment 1

[0052] see Figure 1-10 , a four-cylinder diesel engine crankshaft for preventing shaking, comprising a crankshaft body 1, the crankshaft body 1 includes a main shaft 102, a plurality of eccentrically arranged connecting rod shafts 103 are fixedly connected to the main shaft 102, and the outer ends of the main shaft 102 are fitted with multiple Two main force shaft half sets 3 arranged in pairs, and a plurality of main force shaft half sets 3 arranged in pairs are respectively arranged at intervals with the connecting rod shaft 103, and the inner wall of the main force shaft half sets 3 is equipped with a plurality of anti-shake lubrication components 4, anti-vibration The outer side of the shaking lubrication assembly 4 is connected with a plurality of damage induction assemblies 5 distributed in circular arcs. The anti-shaking lubrication assembly 4 includes an anti-shaking buffer arc bar 401, and the inner wall of the main shaft half sleeve 3 is provided with a plurality of ...

Embodiment 2

[0065] see Figure 1-11 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 11 , the installation method of crankshaft body 1 comprises the following steps:

[0066] S1. Pre-install the main shaft half sleeve 3 located on the lower side to the crankshaft installation place of the fuel engine casing;

[0067] S2. Then install the crankshaft body 1 into the fuel engine casing, and make the main shaft 102 correspond to the main shaft half sleeve 3 located on the lower side, so that the anti-shake buffer arc 401 snaps into the anti-shake groove 104 of the main shaft;

[0068] S3. Finally, install the upper main shaft half sleeve 3 on the main shaft 102 so that the anti-shake buffer arc 401 snaps into the corresponding main...

Abstract

The invention discloses a diesel engine four-cylinder crankshaft capable of preventing shaking, and belongs to the field of diesel engines. The diesel engine four-cylinder crankshaft capable of preventing shaking comprises a crankshaft body, wherein the crankshaft body comprises a main force shaft, and multiple connecting rod shafts which are eccentrically arranged are fixedly connected with the main force shaft. By making main force shaft half sleeves, anti-shake lubricating assemblies and the crankshaft body match one another, anti-shake buffering arc strips can buffer vibration generated in a transmission process of the crankshaft body, the multiple anti-shake lubricating assemblies and the connecting rod shafts are arranged at intervals, under conditions of a long stroke and a large cylinder diameter, the anti-shake buffering arc strips effectively have an anti-shake effect on the crankshaft body, thus the transmission precision of the crankshaft body is improved, air cylinder motion jamming is reduced, the working efficiency of a diesel engine is improved, the service life of the crankshaft body is effectively guaranteed, and surface contact is changed into electric contact through anti-friction steel balls, so that friction force is reduced, the energy conversion rate of the diesel engine is effectively increased, and the energy utilization rate is increased.

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...
