Abstract

A bearing structure beneficial to lubrication comprises a base body and an alloy layer, wherein the alloy layer is arranged on the section of the base body, and grooves are uniformly distributed on the end face of the base body. The utility model discloses a do benefit to lubricated bearing arrangement through increasing the recess like the picture on the terminal surface of bearing, alright avoid vacuum adsorption's appearance in letting high-speed operation, can deposit a small amount of lubricating oil in the recess during operation simultaneously for lubricated terminal surface, and can satisfy high-speed moving performance.

Description

Do benefit to lubricated bearing arrangement

Technical Field

The utility model relates to a diesel engine technical field.

Background

The oil supply unit of the diesel engine is an important part of the diesel engine, and a reliable lubricating oil path and high-pressure fuel oil need to be provided for the whole diesel engine. In a normal state, the rotation speed of the oil pump gear is about 1000rpm, and high-speed rotation requires extremely high lubrication of the bearing. After the pressure of the lubricating oil is increased to a certain degree, the structure of the bearing is required to be adjusted to meet the requirements of reliable lubrication and minimum abrasion. This puts new demands on the structural design of the bearing.

As shown in fig. 3, the structure of the whole diesel engine equipment, the oil supply unit bearing is composed of the base 1 and the alloy 2 in fig. 2, and the gap between the bearing and the end face of the shaft is required to ensure the roughness of the surface under normal conditions. I.e., the smaller the roughness, the smaller the coefficient of friction, but two excessively smooth surfaces may be present during high speed operation with the vacuum absorption phenomenon. But the problem of rapidly improving the surface in operation causes the oil film to lose efficacy, reduces the lubricating effect and finally causes the ablation phenomenon.

Disclosure of Invention

In order to solve the above-mentioned problem that current diesel engine bearing exists, the utility model provides a do benefit to lubricated bearing arrangement.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: a bearing structure beneficial to lubrication comprises a base body and an alloy layer, wherein the alloy layer is arranged on the section of the base body, and grooves are uniformly distributed on the end face of the base body.

And the end surface of the base body is uniformly distributed with a plurality of grooves.

The utility model discloses a do benefit to lubricated bearing arrangement through increasing the recess like the picture on the terminal surface of bearing, alright avoid vacuum adsorption's appearance in letting high-speed operation, can deposit a small amount of lubricating oil in the recess during operation simultaneously for lubricated terminal surface, and can satisfy high-speed moving performance.

Drawings

Fig. 1 is a main sectional structure view of the bearing beneficial to lubrication.

Fig. 2 is a side view structural diagram of the bearing beneficial to lubrication.

FIG. 3 is a block diagram of a bearing assembly to facilitate lubrication.

In the figure: 1. the bearing comprises a base body, 2, an alloy layer, 3, a groove, 4, a bearing, 5, a gear, 6 and an oil pump.

Detailed Description

The utility model discloses a do benefit to lubricated bearing arrangement is shown in fig. 1 and fig. 2, including base member 1 and alloy-

layer

2, 1 section of base member is equipped with alloy-

layer

2, 4 recesses 3 of evenly distributed on the 1 terminal surface of base member.

The groove is added in the processing process at the position of the end face of the bearing as shown in a circle in figure 1, so that the vacuum adsorption can be avoided in high-speed operation. And a small amount of lubricating oil can be stored in the groove during operation and is used for lubricating the end face. And can satisfy the usability in high-speed operation. Through the use of the bearing bush which is compared with the bearing bush without the groove processing technology, the ablation phenomenon can occur within 10000h of the average service life. The service life of the bearing bush adopting the groove processing technology can be far more than 50000 h.
