Diesel engine bearing cover

Abstract

The invention relates to a diesel engine bearing cover. The diesel engine bearing cover comprises a bearing cover 1 and installing fixing holes 2 formed in two sides of the bearing cover 1. The middle of the bearing cover 1 is provided with an oil adding hole 3, a semicircular inner side wall of the bearing cover 1 is provided with an H-shaped oil groove 4, and the oil adding hole 3 is communicated with the center of the H-shaped oil groove 4. The oil adding hole 3 is a threaded hole and screwed in through a sealing screw 5. The H-shaped oil groove 4 is an H-shaped two-side groove and is arranged in the circumferential direction of the bearing cover 1. The diesel engine bearing cover is simple in structure, lubricating oil is added conveniently, a large-area lubrication oil film can be formed, and a whole crankshaft journal is lubricated well.

Description

technical field [0001] The invention relates to the field of engine lubricating systems, in particular to a diesel engine bearing cap. Background technique [0002] The lubrication system is an important part of the engine, and the failure of the lubrication system will not only reduce the output power of the engine, but also seriously affect the service life of the engine. The bearing cap and the camshaft are the components of the engine lubrication system. The function of the bearing cap is to position the camshaft and prevent the camshaft from beating during operation. The camshaft rotates at a high speed in the hole formed by the bearing cap and the cylinder head. Existing engines generally use lubricating oil to enter the oil groove of the bearing cover through the oil channel on the camshaft under the action of oil pressure and high-speed rotating centrifugal force, and then under the action of continuous oil pressure, the lubricating oil passes through the hole betwee...

AI Technical Summary

Problems solved by technology

Existing engines generally use lubricating oil to enter the oil groove of the bearing cover through the oil channel on the camshaft under the action of oil pressure and high-speed rotating centrifugal force, and then under the action of continuous oil pressure, the lubricating oil passes through the hole between the camshaft and the bearing cover. The gap spreads to both ends of the bearing cover, thereby forming a lubricating oil film under the high-speed rotation of the camshaft. Because the bearing cover of the engine adopts a sealed design, and because the bearings are in good operation, lubricating oil needs to be added regularly, otherwise it will affect the use of the internal bearings of the engine. life, and often when adding lubricating oil inside the engine, it is necessary to remove the bearing cover as a whole, which is very inconvenient when adding lubricating oil
