The structure and characteristics of rolling bearings

Under normal circumstances, the correct choice of bearing lubrication method determines the conditions and life of the triple gear oil pump bearing, so this is also a very important part of the gear pump design. At present, three gear oil pumps have the following lubrication methods: using high-pressure leaking oil for lubrication;

Grease in bearings: the importance of choosing grease

The grease used in the bearing must have an anti-rust effect,and the anti-rust agent is preferably insoluble in water.The grease should have good adhesion to form an oil film on the surface of the steel,even if the grease is filled with water,it can be maintained.

Which factors must be considered in bearing selection?

"Various types of bearings have different characteristics due to their different designs.Due to the variability and complexity of the specific mounting position of the bearing and the application,the selection of the non-fixed mode of the bearing type can be adapted to the specific mounting position of a certain host When selecting bearing types based on application conditions,it is recommended to consider the following major factors.

Seven measures can improve the reliability of engine main shaft bearings

In recent years, silence has been an important technical indicator of hydraulic gear oil pumps. However, because the flow rate and pressure pulsation of gear oil pumps are inherent characteristics, the causes of noise are more complicated, and it is often difficult to find noise generation only from theoretical analysis.
