Software für technische Berechnungen im Maschinenbau

Info

Die MESYS AG in Zürich entwickelt Software für technische Berechnungen im Maschinenbau. Der Schwerpunkt ist die Auslegung von Maschinenelementen (Verzahnungen, Wälzlager, Schrauben, …). Neben Standardsoftware wird auch kundenspezifische Software entwickelt. Wir unterstützen Sie auch in der Auslegungen von Maschinenelementen insbesondere von Verzahnungen oder bei der Erstellung von Festigkeitsnachweisen mit moderner Berechnungssoftware. Als Standardprodukte bieten wir Software für die Berechnung von Wälzlagern nach ISO/TS 16281 und eine dazugehörige Wellenberechnung oder Wellensystemberechnung an. Die MESYS Wälzlagerberechnung wird bereits von Kunden aus 24 Ländern auf 4 Kontinenten eingesetzt. Zusätzlich vertreiben wir die Standard Maschinenelementberechnung eAssistant, TBK2014 und den GearEngineer von GWJ Technology sowie die Gear Production Suite von Dontyne Systems.

    The final drafts ISO/FDIS 16281 and ISO/FDIS 17956 are available for voting now. ISO/FDIS 16281 is an update of the existing ISO/TS 16281. The technical content is unchanged, but it includes some clarifications and has proper coordinate systems. Hybrid bearings are now mentioned too. ISO/FDIS 17956 defines the calculation of an effective static safety factor and requires the load distribution within the bearing to be known as in ISO 16281. The effective static safety factor is then calculated based on the rolling element load. This allows to see an influence of clearance or misalignment. As ISO 16281 extends ISO 281 by considering the actual load distribution, ISO 17956 extends ISO 76 by considering the actual load distribution.

    In case of hollow shafts centrifugal forces lead to a radial expansion and an axial shortening of the shaft. This can be considered in the MESYS Shaft Calculation by using FEA based 3D-elastic parts. In this example the left bearing is fixed and the right bearing has a spring pretension. The axial movement of the left end of the shaft is -10µm and the axial movement on the right end is -20µm. Therefore the shaft is shortened by 10µm at 20'000rpm.

    Track roller bearings usually have a point (or line) load to the outer ring and therefore a thicker outer ring. The MESYS Rolling Bearing Calculation allows to calculate reduced working load ratings Cw and C0w for track rollers based on a FEA-beam model for the outer ring. Maximum contact stress and minimum life are calculated when the load is applied on the position of a rolling element, while the maximum stresses in the ring occurs if loaded between two rolling elements.

    If two gears are connected by two intermediate gears with the same geometry in both load paths, how is the load shared between the gears? In the example below for equal backlash in both paths the upper intermediate gears transmits 64% of the power based on the stiffness in the coupled system calculation. Because of the direction of the gear forces the upper shaft is pulled into the contact which leads to reduced backlash. The lower shaft is pushed out off the contact leading to larger backlash. This results for the load sharing should not be taken for real as there are tolerances and also not all stiffnesses are considered in this model. There should be a possibility to adjust the backlash during mounting of the system. The diagram shows the load sharing in the two paths based on the backlash of the upper path. An increase of the backlash in the upper path improves the load sharing between the gears. In the design of a system with different load paths the problem with load sharing should be considered.

    Several customers asked about contact dimensions for ball bearings, like half axes of contact ellipses or contact surface. The half axes for all contact ellipses had been available as numerical results for long time in result tables. In version 06/2024 also a diagram for contact dimensions was added to the MESYS Rolling Bearing Calculation. In addition to the half axes of the contact ellipse the contact area is also directly available. Like for all diagrams, the data values can be exported into a table for further processing.

    Napoleon Engineering Services provided an encrypted database including internal geometry for split inner ring three point bearings for MESYS Software version 06/2024. The database is included in the standard installation. The split ring three point bearings are something between a four point bearing and a deep groove ball bearing having one raceway with one full arc and another with a gothic arc. Thie bearing is suited mainly for axial loads in both directions and has less axial clearance than a deep groove ball bearing. Some technical backgound is shown at https://lnkd.in/ePcfJWGV
