Equivalent dynamic bearingload

Radial load Fig 4 When considering load, a distinction ismade between:•load direction–radial loads ( If the load acting on • radial and angular contact sphericalplain bearings is purely radial• spherical plain thrust bearings ispurely axial• rod ends is purely radial and also inthe direction of the shank axisand is of constant magnitude, then theload can be directly inserted in the equation for the specific bearing load p ( âž” fig
4 )–axial loads ( âž” fig
5 )–combined (axial and radial) loads( âž” page30 )should be followed. âž” fig
6 )•the way in which the load acts –loads of constant direction ( âž” page21 ). In all other cases it isnecessary to calculate the equivalent dynamic bearing load P. If the load is not of constant magnitude, then the procedure given under “Variable load and sliding velocity” (
Axial load Fig 5 âž” fig ),change direction so that loaded zones at opposite positions in the bearing are continuously loaded and unloaded•the type of load –dynamic load is when sliding move-ment takes place in the loaded bearing–static load is when no movementtakes place in the loaded bearing. âž” fig
7 ), i.e. the direction inwhich the load is applied does not change and the same part of the bearing (loaded zone) is always subjected to the load–alternating loads (
