Problems solved by technology

However, on the one hand, the oil grooves are spaced apart from each other in the circumferential direction, resulting in unsatisfactory distribution of lubricating oil on the friction surface; Under the circumstances, the oil will be thrown out radially under the action of centrifugal force while traveling in the circumferential direction, and the radial oil groove provides a channel for the oil to be thrown out, resulting in oil loss, which obviously reduces the impact of the oil on the gasket. Lubrication effect, shortening the service life of the gasket
Moreover, general gaskets only consider applying a layer of lubricating grease during installation, or periodically replenishing lubricating grease, and do not consider continuous lubrication
[0004] Generally, gaskets are cheap components, and they are used in large quantities. The installation location is relatively hidden and inconvenient to disassemble. Therefore, maintenance personnel are required to regularly add lubricating grease to gaskets or replace gaskets regularly. The labor cost is much higher than the cost of gaskets.
In fact, the maintenance personnel generally wait for the wear of the gasket to exceed a certain limit, which will cause problems such as loud noise or other faults in the engine and other devices, before passively replacing the gasket

Embodiment Construction

[0027] figure 1 A fuel pump drive mechanism in an engine timing train employing a spacer 100 is shown by way of example. Of course, those of ordinary skill in the art should understand that the gasket 100 can also be used in other timing trains such as generator drive mechanisms, or in other positions of the engine with shaft parts and gear parts, or in other parts of the automobile. Location. The gear 500 is driven by power from the crankshaft to drive the shaft 200 to rotate in the shaft hole of the flange 400 , and the flange 400 is fixedly installed on the cylinder body 300 . The washer 100 is sleeved on the shaft 200 and located between the gear 500 and the flange 400 . An oil passage 410 for supplying oil to the annular oil groove 210 on the shaft 200 is processed on the flange 400 , and the annular oil groove 210 serves as an oil passage for supplying oil to the gasket 100 .

[0028] refer to figure 2 , the gasket 100 is annular, with an inner circle 110 and an out...

Abstract

The invention discloses a gasket which is circular. The surface of the gasket is provided with an oil groove which is provided with openings at both the inner circle and the outer circle of the gasket. The oil groove is planar and spiral and surrounds the inner circle for at least one circle. The invention also discloses an engine with the gasket and a car with the gasket. The gasket can be continuously lubricated by an oil circulation lubricating system of the engine, and the lubricating effect is good.

Description

technical field [0001] The invention relates to the fields of machinery and automobiles, in particular to a gasket with a plane helical oil groove, and an engine and an automobile using the gasket. Background technique [0002] Ring gaskets are often used in shaft transmissions, such as engines or other engineering machinery, to adjust installation accuracy, axial positioning, thrust, etc. [0003] Generally, the installed gasket will generate friction with the surrounding parts that are in contact with it and undergo relative motion during the working process, so the gasket needs to be lubricated. Under the existing technical conditions, one way is to open holes on the gasket. The more holes are opened, the larger the lubricating surface is, and the better the lubricating effect is. However, the more holes there are, the poorer the rigidity and strength of the gasket, and the poorer the ability to bear axial force. Another way is to process oil grooves on the gasket. Gene...
