Tapered Land Thrust Bearing

In most designs a flat land extends an additional 10 to 20 of the.

Tapered land thrust bearing.

The surfaces of the pads and the thrust collar are in parallel by design. Purpose to make an oil film break of lubricating oil so as not to happen there as well as to prevent the occurrence of cavitation erosion by removing an angular end in a corner angle of a tapered land end part and thereby forming it into a smooth spherical form. Tapered land bearings are ideal for use in mid to large sized high speed machines and thrive on consistency. The flat land bearing is the simplest design formed from a washer shaped plate with radial grooves to channel fluid to the bearing surface see image 3.

Pad crown can be present and modeled for the tilting pad thrust bearing particularly when the pivot is centrally located. Tapered land thrust bearing there are three basic types of hydrodynamic thrust bearings used in industrial rotating machinery. For applications with low thrust loads limited space and negligible misalignment bearings plus designs and supplies thrust plates with simple or compound taper land faces. Thrust bearings are usually classified as fixed geometry or tilting pad.

Our extensive offering of tapered roller bearing combi nations provides equipment builders and operators simple reliable and less costly. Constitution plural tapered lands 14 being successively made up in the circumferential direction of a sliding bearing surface 12 are. Tapered land bearings use lubricating oil to provide additional thrust load capacity where it is necessary. The source of its load carrying capacity was extensively.

Depending on size and predicted bearing temperatures under the designed load and oil viscosity thrust plate bearing materials can include babbitt copper bronze and polymer. The dam shroud can be present at inner and outer diameters for the taper land. Figure 1 shows a simple flat land fixed geometry bearing. Due to the lack of obvious converging wedge this bearing is only suitable to carry a light thrust load 0 5 mpa or 75 psi.

Flat land thrust bearings will never hold more than 20 to 25 of the load supported by their tapered land or stepped counterparts which have physical wedges to pressurize oil in the direction of. Rayleigh step thrust bearing with uni or bi directions. Tapered land bearings are essential to delivering the results you expect and need.
