What are the structural types of radial and thrust dynamic journal bearings?
The vertical axis of the radial sliding bearing is the symmetrical surface of the bearing, that is, the middle of the ball or cylindrical rollerThe thrust roller bearings are asymmetric on both sides of the vertical axis, that is, the roller in the middle of the cone is the force of the axial thrust
The upper and lower two parts are bolted together. The bearing cover is provided with an oil cup. In order to install, it is easy to have a ladder shaped locating stop on the middle and the parting surface, and the small oil pipe in the upper oil hole of the bearing also has a stopping effect. Split bearings are easy to assemble and disassemble, so they are widely used.Thrust bearing is the axial thrust and limit shaft axial movement of the sliding bearing. The two frictional surfaces of hydrodynamic thrust bearings and hydrostatic thrust bearings are completely separated by fluid membranes and are suitable for high and high speed operation. The two friction surface, which is not completely separated by the fluid film, works under the boundary lubrication and is suitable for low speed operation.Turn left and turn right |
There are many kinds of sliding bearings, which can be divided into two kinds of radial (Xiang Xin) sliding bearing and thrust (axial) sliding bearing according to the direction of bearing load.Sliding bearings can be divided into integral and partial and integral type sliding bearings with bolts connected with the frame. The bearing seat hole pressure, the bearing seat is arranged on the top of an oil sleeve on the oil hole. The integral sliding bearing is simple in structure, but the bearing clearance can not be adjusted when the working surface of the bearing is too large. The journal can only be loaded from the end. Split sliding bearings are mainly composed of bearing housings, bearing housings, split upper and lower bearings.
