The type of Sliding Bearing
2017-10-12
The bearing is a rotating part that supports the journal or shaft.
According to the working principle of the bearing can be divided into: rolling friction bearings (rolling bearings) and sliding friction bearings (sliding bearings).
Sliding bearings: If the surface of the sliding bearing can form a lubricating membrane to separate the moving sub-surface, the sliding friction can be greatly reduced, and the wear is avoided because the moving sub-surface is not in direct contact. Sliding bearing bearing capacity, high rotation accuracy, lubricating film with impact resistance, therefore, in the project to obtain a wide range of applications.
The formation of the lubricating film is the basic condition for the plain bearing to work normally. The factors that affect the formation of the lubricating film are the lubrication method, the relative movement speed of the moving pair, the physical properties of the lubricant and the roughness of the moving surface. The design of the sliding bearing should be based on the bearing working conditions, determine the type of bearing structure, select the lubricant and lubrication methods and determine the bearing geometry.
The type of sliding bearing
According to the direction of the load is divided into:
Thrust plain bearings: Thrust plain bearings are parallel to the shaft centerline.
Radial plain bearings: Radial sliding bearing force perpendicular to the center line of the shaft.
According to the formation of lubricating film different principles are divided into:
Dynamic sliding bearings: the relative movement of the relative movement of the surface and the shape of the surface, by means of fluid viscosity, the lubricant into the friction between the surface, relying on the natural establishment of the fluid pressure membrane, the movement of the surface separation of the lubrication method for fluid power lubricating.
Static pressure sliding bearings: in the sliding bearing and journal surface between the high pressure lubricant to withstand external load, so that the movement of the surface separation of the lubrication method to become hydrostatic lubrication.
