MESYS rolling bearing analysis
Professional rolling bearing calculation and analysis software developed by Swiss MESYS AG
ABOUT software
MESYS rolling bearing calculation and analysis software is a professional rolling bearing calculation and analysis software developed by the Swiss company MESYS AG. The rolling bearing calculation and analysis software MESYS calculates the strength and life of rolling bearings in accordance with the ISO/TS 16281 standard. In the calculation, the detailed geometric dimensions of the bearing are considered, and the load distribution inside the bearing is considered.
Product Advantage
The software provides a basic material database and lubricant database, and commonly used materials and lubricant properties can be extracted from the database. The results of bearing calculation and analysis are output in the form of text reports, curves and graphs. The software automatically generates analysis reports.
In addition to calculating and analyzing individual bearings, it is also possible to calculate and analyze bearing groups. The software can consider the influence of a variety of parameters: bearing clearance, changes in bearing clearance due to fit and stability, centrifugal force, lubrication, roller profile, load spectrum, elastic deformation, and installation of bearings integrated on the shaft.
The user can provide the internal geometric dimensions of the bearing for calculation and analysis, or the geometry can be approximated by the software according to the bearing capacity for calculation and analysis. The calculation can get the pressure distribution on the ball or roller and the reference life under the set load (force and moment) according to the ISO/TS 16281 standard.
It can be easily obtained by calculation: load distribution in the bearing, Hertzian contact stress, subsurface stress for selecting the required harness depth, load-related friction moment of the ball bearing, contact angle under load, displacement and tilt of the bearing, minimum film thickness, Rotation roll ratio, extension of pressure omitted, load distribution in a set of bearings.
Application Field
MESYS rolling bearing calculation and analysis software is a professional rolling bearing calculation and analysis software developed by the Swiss company MESYS AG. The rolling bearing calculation and analysis software MESYS calculates the strength and life of the rolling bearing in accordance with the ISO/TS 16281 standard. In the calculation, the detailed geometric dimensions of the bearing are considered, and the load distribution inside the bearing is also considered.
The main function
The rolling bearing calculation and analysis software MESYS calculates the strength and life of rolling bearings in accordance with the ISO/TS 16281 standard. In the calculation, the detailed geometric dimensions of the bearing are considered, and the load distribution inside the bearing is considered. The main functional modules are as follows:
Single bearing calculation under tilting moment
- Under normal circumstances, you will try to avoid the tilting moment on the bearing, but on track rollers or slewing bearings, the tilting moment may be the main load. For roller bearings, the effect of tilt on load distribution or life can be checked.
Angular contact bearing set calculation
- Angular contact bearings are often used in combination bearings, but the load distribution between single bearings is difficult to evaluate. The software can calculate the load distribution, life and stiffness of the bearing according to the preload of the bearing group. The preload can be set individually for each bearing. Allows the user to check whether the pretension is large enough and whether the bearing is under load under each load condition.
Calculation of the influence of clearance and preload
- The influence of bearing clearance and preload on bearing life and load distribution can be evaluated. The nominal gap can be selected according to the C2...C4 standard, or directly provided as a number. Bearing tolerance grade can be selected as P0...P2, shaft and housing tolerance can be selected as ISO 286. You can also directly specify the fit as a number. Bearing fit, thermal effect and centrifugal load cause the change of clearance to determine the running clearance.
High-speed rotating bearing calculation
- In most cases, the load on the inner ring of the bearing is higher than the outer ring. For high-speed working conditions, it may change as the centrifugal load changes. The contact angle will also change.
Four-point slewing ring calculation
- Large slewing bearings use different bearing types: one or two rows of four-point bearings and three sets of roller bearings. The software can analyze the configuration of one or two rows of four-point bearings. The important results are contact stress, friction moment and shear stress under the surface to determine the necessary hardness depth. According to NREL DG03 life and static safety calculation guidelines, the hardness of the seat ring should be reduced. The calculated contact stress id at all four (or eight) contact points. So the user can see if the 4-point contact occurred and how often. In a calculation using the load spectrum, multiple load cases can be considered.
