Tapered Land Thrust Bearing Design

Flat thrust plate bearing design formulas and calculator.

Tapered land thrust bearing design.

Machinery s handbook by eric oberg franklin d. Tapered land bearings provide reliable designs for a large variety of midsize to large high speed machines such as turbines and pumps. In most designs a flat land extends an additional 10 to 20 of the. Horton industrial press inc new york ny 10157.

This chapter discusses six common types of thrust bearing. In a tapered land thrust bearing design variables include the slope width. The analysis takes account of the two dimensional reynolds and energy equations and the hot oil carry over between the pads. Complete analysis requires consideration of heat generation oil flow bearing material load capacity and stiffness.

Thrust bearing typical loads. Tapered land thrust bearings find use in mid to large sized high speed machines such as turbines compressors and pumps. Step thrust plate bearing design formulas calculator. In many outlines a level area extends an extra 10 to 20 of the circumferential expansiveness b at the trailing edge of every section.

Tapered land thrust plate bearing design equation and calculator. Full bolt screw bearings are held together by special positioning components. Pivoted pad thrust bearings springs or other flexible supports step bearings flat landbearings tapered land bearings and hydrostatic thr. Tapered land thrust plate bearing design calculator.

The rollers incorporated in skf tapered roller thrust bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. Tapered thrust plate bearing. Max loads lbs in 2. Steady wear expands this level bit to around.

Jones and holbrook l. Optimum values of taper land geometry are given. A computer analysis of oil lubricated pad taper land bearings of varying geometries enables load flow and power loss to be calculated from non dimensional design graphs. Tapered land thrust bearing tilting pad thrust bearing and hydrodynamic pocket thrust bearing.

This provides optimal load distribution and enables the bearings to accommodate heavy axial loads. The tapered thrust bearing with cage is a split design so that the two washers as well as the roller and cage thrust assemblies can be easily installed separately. Parallel surface 75 150. Richard booser mcgraw hill book company new york ny.

For ease of operation the washers have threaded holes for lifting bolts. This augmentation can help load limit 10 to 15 and lessen wear amid begins stops and at low speeds.
