Abstract
The invention discloses a crankshaft thrust plate lubricating structure, which comprises: the main bearing, the thrust plate and the main bearing cover. The main oil duct is arranged in the main bearing, an oil inlet hole is formed in the main oil duct, and lubricating oil enters the main oil duct through the oil inlet hole. The thrust plates are arranged on the end faces of the two sides of the main bearing in pairs, and lubricating oil channels are formed in the thrust plates. And the main bearing cover compresses the main bearing from the upper part and is fixed on the machine body by bolts penetrating through the bolt holes of the main bearing. The inlet of a lubricating oil passage of the thrust plate is communicated with the main oil passage, and the outlet of the lubricating oil passage is arranged on the outer side of the thrust plate. Therefore, the crankshaft thrust plate lubricating structure is simple and reasonable in structure, the fault rate of the thrust plate is reduced, and the reliability of the whole machine is improved.
Description
Technical Field
The invention relates to the technical field of engine lubrication, in particular to a crankshaft thrust plate lubricating structure.
Background
At present, a crankshaft thrust plate is not provided with a special lubricating oil channel, and dry grinding is easily caused on a large machine type, so that the whole machine is in failure.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Disclosure of Invention
The invention aims to provide a crankshaft thrust plate lubricating structure which is simple and reasonable in structure, reduces the fault rate of a thrust plate and improves the reliability of the whole machine.
In order to achieve the above object, the present invention provides a crankshaft thrust plate lubrication structure, including: the main bearing, the thrust plate and the main bearing cover. The main oil duct is arranged in the main bearing, an oil inlet hole is formed in the main oil duct, and lubricating oil enters the main oil duct through the oil inlet hole. The thrust plates are arranged on the end faces of the two sides of the main bearing in pairs, and lubricating oil channels are formed in the thrust plates. And the main bearing cover compresses the main bearing from the upper part and is fixed on the machine body by bolts penetrating through the bolt holes of the main bearing. The inlet of a lubricating oil passage of the thrust plate is communicated with the main oil passage, and the outlet of the lubricating oil passage is arranged on the outer side of the thrust plate.
In one embodiment of the present invention, the main oil gallery is perpendicular to one end of the lubricating oil gallery.
In one embodiment of the present invention, the lubricating oil passage includes a lateral oil passage and a longitudinal oil passage that communicate with each other.
In one embodiment of the present invention, the thrust plate has a semicircular plate structure.
Compared with the prior art, the crankshaft thrust plate lubricating structure is simple and reasonable in structure, the fault rate of the thrust plate is reduced, and the reliability of the whole machine is improved.

Description of the main reference numerals:
1-main bearing, 2-main oil duct, 3-thrust plate and 4-lubricating oil duct.
Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
Fig. 1 is a schematic structural view of a part of a lubricating structure of a crankshaft thrust plate after being assembled according to an embodiment of the invention. As shown in fig. 1, a crankshaft thrust plate lubricating structure according to a preferred embodiment of the present invention includes: main bearing 1, thrust plate 3 and main bearing cap. The main oil gallery 2 is arranged in the main bearing 1, an oil inlet hole is formed in the main oil gallery 2, and lubricating oil enters the main oil gallery 2 through the oil inlet hole. The thrust plates 3 are arranged in pairs on the end faces of the two sides of the main bearing 1, and the thrust plates 3 are provided with lubricating oil channels 4. And the main bearing cover presses the main bearing 1 from the upper part and is fixed on the machine body through a bolt hole of the main bearing by a bolt. Wherein, the inlet of the lubricating oil passage 4 of the thrust plate 3 is communicated with the main oil passage 2, and the outlet of the lubricating oil passage 4 is opened at the outer side of the thrust plate 3.
In one embodiment of the present invention, the main gallery 2 is perpendicular to one end of the lubricating oil gallery 4. The lubricating oil passage 4 includes a lateral oil passage and a longitudinal oil passage that are communicated with each other. The thrust plate 3 is a semicircular plate structure.
In practical application, the crankshaft thrust plate lubricating structure disclosed by the invention has the advantages that holes are drilled in the main bearing 1 and are communicated with the main oil duct 2 (the lubricating oil duct 4 of the thrust plate 3) of the engine body, the pressure of the main oil duct 2 is higher than that of an engine crankcase, engine oil is sprayed out and splashed onto a crankshaft counterweight block, and after accumulation, the engine oil flows onto the thrust plate 3, so that the fault rate of the thrust plate 3 is reduced.
In a word, the crankshaft thrust plate lubricating structure is simple and reasonable in structure, the fault rate of the thrust plate is reduced, and the reliability of the whole machine is improved.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
