Abstract
The invention provides a camshaft for a diesel engine with a vertical shaft structure, wherein an impeller is arranged at the bottom of the camshaft, the cross section of blades uniformly distributed on the impeller is of a zigzag type, one end of each blade extends to the center of the impeller, the other end of each blade extends to the periphery of the impeller, and the rotation direction of each blade is the same as that of the camshaft. The bottom of the camshaft is uniformly provided with the convex blades, so that the lubricating capability between each cylinder rocker arm, the valve and the push rod of the camshaft is improved, the gravity of the camshaft is balanced, and the reliability of a vertical diesel engine is improved.
Description
Technical Field
The invention belongs to the technical field of engine mechanical parts, and particularly relates to a camshaft for a diesel engine with a vertical shaft structure.
Background
At present, the diesel engine with a vertical shaft structure adopts splash lubrication between the rocker arm and the valve, and between the rocker arm and the push rod, the splash lubrication cannot meet the lubrication requirements between the rocker arm, the valve and other parts due to the influence of gravity.
Disclosure of Invention
In view of this, the invention aims to provide a camshaft for a diesel engine with a vertical shaft structure, and the camshaft is provided with a blade structure, so that the gravity of the camshaft is balanced, and the lubrication reliability of the camshaft can be improved.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
the invention has the following inventive concept: according to the rotation of the impeller, the engine oil generates splashing, the lubricating capability is improved, and the self gravity is balanced.
The utility model provides a camshaft for vertical axis structure diesel engine, the bottom of camshaft sets up the impeller, the cross-section of the blade of equipartition is the broken line type of class on the impeller, and one end extends to the impeller center, and the other end extends to the periphery department of impeller, and the direction of rotation of blade is the same with the direction of rotation of camshaft.
Further, the bottom of the cam shaft is provided with an impeller in an interference fit mode, or the impeller is installed through a bolt, or the cam shaft and the impeller are integrally formed.
Compared with the prior art, the invention has the following advantages:
the bottom of the camshaft is uniformly provided with the convex blades, so that the lubricating capability between each cylinder rocker arm, the valve and the push rod of the camshaft is improved, the gravity of the camshaft is balanced, and the reliability of a vertical diesel engine is improved.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1, a camshaft 1 of a vertical axis diesel engine is vertically arranged, an impeller is arranged at the bottom of the camshaft 1 in an interference manner, blades 2 are uniformly distributed on the impeller, the cross sections of the blades are of a zigzag type, one end of each blade extends to the center of the impeller, the other end of each blade extends to the periphery of the impeller, and as shown in fig. 3, the rotating direction 5 of each blade 2 is the same as the rotating direction of the camshaft 1; the impeller can also be connected by bolts, or the camshaft 1 and the impeller are integrally machined. The camshaft 1 is driven by the engine transmission system.
The working process is as follows:
camshaft 1 is driven by engine transmission system, along with camshaft 1's rotation, blade 2 is rotatory, has accelerateed the flow of machine oil for machine oil produces bigger splashing, as shown in figure 2, improve rocking arm 3 and valve 4 of each jar of camshaft 1, lubricating ability between the push rod, along with blade 2's rotation, can produce the axial force moreover, the self gravity of balanced camshaft 1, thereby guarantee the axial clearance between camshaft 1 and the cylinder cap, guarantee the reliable work of vertical axis diesel engine.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
