What is the load strength of the oil bearing

Qinhuangdao Zhongwei Precision Machinery Co., Ltd. has special equipment for powder metallurgy, strong technical force, advanced technology and perfect powder metallurgy process detection method. The company mainly produces powder metallurgy processes and sells copper based, iron based and copper - iron alloy powder metallurgy products containing oil. As a professional oil bearing manufacturer of powder metallurgy process, let's talk about how strong the bearing capacity of oil bearing is.

In our laboratory, we clearly found that the bearing capacity of bearings is often related to the eccentricity and friction coefficient of oil-bearing bearings. We're not going to explain everything to you here.

Let's talk about how to increase carrying capacity:

Oil-bearing has the characteristics of low cost, vibration absorption, low noise, no need to add lubricating oil in a long working time, especially suitable for the work environment that is not easy to lubricated or does not allow oil dirty. Porosity is an important parameter of oil bearing.

Self-lubricating bearing manufacturers

Oil bearing working under high speed and light load requires more oil content and high porosity; Oil bearing working at low speed and large load requires high strength and low porosity. This kind of bearing was invented in the early 20th century. Because of its low manufacturing cost and convenient use, it has been widely used. It has become an indispensable basic part for the development of various industrial products such as automobiles, household appliances, audio equipment, office equipment and agricultural machinery.

Through continuous experiments, it can be found that when the eccentricity of oil-bearing bearings is large, the corresponding bearing capacity will be increased, and the friction coefficient of bearings will be reduced. However, the change of eccentricity value of oil-bearing bearings is relatively passive, and it will not be changed autonomously when in use. Therefore, the larger the bearing load is in the process of use, the greater the bearing eccentricity will increase, and the bearing capacity will continue to increase.

In this series of experiments, it can be found that the load capacity, eccentricity, friction coefficient and other aspects of oil-bearing will affect each other in the process of use.

There are many ways to improve the load capacity of oil-bearing and reduce the friction coefficient of bearing.

Self-lubricating bearing manufacturers

The common way is to improve the load capacity of oil-bearing bearings by adjusting the permeability of bearings. The main operation mode is to properly reduce the permeability of the bearing material, which can improve the load capacity of the bearing and ensure that the oil-bearing has a small friction coefficient. But the permeability of oil-bearing can not be reduced indefinitely, because too small permeability will make the oil content inside the bearing is insufficient, so that the bearing can not get enough lubrication.

Self-lubricating bearing manufacturers point out that by optimizing the two parameters of bearing permeability and oil content, it can effectively improve the load capacity of oil-bearing and reduce the friction coefficient of bearing.

In general, we greatly reduce the friction coefficient of oil-bearing by adjusting the permeability of oil-bearing. Here we need to remind you that the permeability of oil-bearing bearing in powder metallurgy process cannot be reduced all the time, because the unreasonable ultra-low permeability will make the oil content in the oil-bearing insufficient, resulting in insufficient bearing lubrication.
