A bearing is a machine element that constrains relative motion and reduces friction between moving parts to only the desired motion. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent ...
Simplified Calculation MethodsShallow FoundationBottom SurfaceSizeEccentric LoadDirect calculating method was deduced from the requirements of pressure on foundation bottom surface to avoid loop computing and verified by an example.

δ is a function of the load on the ball bearing, the sum of the curvatures, the materials of the bodies in Calculation procedure The calculation procedure consists of defining the initial and final coordinates of the centres of curvature, studying the contacts between diagonally opposed centres...
Figure03shows the sequence for the statistic tolerance analysis in this example. The calculation is configured in an XML file in which the components and the form and position deviations are defined. The samples are then automatically created based on the input file and the configured sampling stra...
Each bearing section is wedge shaped, as shown at the right below, for the purposes of design calculation, it is considered to be a rectangle with a length b equal to the circumferential length along the pitch line of the section being considered and a width a equal to the difference in ...
In the calculation, the axial load is only taken into account from a certain ratio to the radial force, otherwise it is assumed to be "0". This condition applies in our example and reduces the test to a purely radial load. 5 test items can be verified simultaneously. On the one hand,...
Simple Calculation of Tank Semi-trailer Bearing Coefficient The longitudinal center and bearing coefficient of tank semi-trailer was simply calculated by Excel.Time was saved and efficient was improved compared with... Yu Yan-hua - 《Special Purpose Vehicle》 被引量: 0发表: 2011年 Trailers and ...
Calculation of centre of rotation The centre of rotation of the talus relative to the calcaneus was determined as the central pivot of the talus at the subtalar joint axis. A sphere fitting approach21was used, assuming the centre of rotation to be stationary and lying on the helical axis62(...
For each bearing type, a data base which contains boundary dimensions, basic load ratings, limiting speeds, mass, company name and load factors of bearings is created. Knowledge about bearing type suitability, seals, lubrication, and fits and tolerances is also stored in separate data bases. Inpu...
