(Unit: N)

Thermal load on the inner ring

The thermal load is uniformly distributed over the body. In other words, this is the ambient operating temperature.

(Unit: C)

Thermal load on the outer ring

The thermal load is uniformly distributed over the body. In other words, this is the ambient operating temperature.

(Unit: C)

Elasticity modulus of the ball

Enter the elasticity modulus of the material of the ball.

Usually, the balls of bearings are made of steel and the elasticity modulus equals to 210 GPa. In special applications the balls can be made of high performance ceramic materials.

(Unit: GPa)

Elasticity modulus of the inner race

Enter the Elasticity modulus of the material of the inner race.

Usually, the races are made of steel and the elasticity modulus of steel equals to 210 GPa.

(Unit: GPa)

Elasticity modulus of the outer race

Enter the elasticity modulus of the material of the outer race.

Usually, the races are made of steel and the elasticity modulus of steel equals to 210 GPa.

(Unit: GPa)

Poisson's ratio of the ball

Enter Poisson's ratio of the material of the ball

Usually, the balls of bearings are made of steel and the Poisson's ratio equals to 0.3. In special applications the balls can be made of high performance ceramic materials.

(Unit: )

Poisson's ratio of the inner race

Enter Poisson's ratio of the material of the inner race.

Usually, the races are made of steel and the Poisson's ratio of steel equals to 0.3.

(Unit:)

Osculation

Enter the osculation of the contact between inner race and balls
$http://latex.codecogs.com/gif.latex?fs = rs $/Dw$
fr = rs/Dw
Where: fr = Osculation
Dw = Nominal diameter of the balls (mm)
rs = Radius of the gothic arcs of the races ()

(Unit: )

Number of balls in the bearing

This is the total number of rolling elements in the ball bearing

(Unit: )

Force on balls

Input the expected maximum contact force on the balls.
This is a coarse estimation of the force excerting on balls. Estimated value should be high enough to bound the actual value. At the same time, the value should not be exaggerated, since exaggeration may negativelly affect the quality of the result.

(Unit: N)

Ball nominal diameter

Input the value of the nominal diameter of the rolling elements. A ball with the size of the nominal diameter leads to no pretension.

(Unit: mm)

Pitch circle diameter

Enter the value OR leave blank

When the input is not assigned here, the value is calculated automatically from the corresponding outside and inside diameters of the inner and outer races.

(Unit: mm)

Ball oversize of radius

This is the amount of pretension in the precision bearings. Pretension impedes the rolling elements from creating backlash. In the oversized ball preloading method, slightly oversized balls are used to prevent backlash. The amount of ball oversizing varies and is directly related to the stiffness.

At the same time, higher pretension leads to faster wearing of the race ways of the balls.

(Unit: µm)

Outer diameter of inner race

Enter the outer diameter of the inner race.

(Unit: mm)

Outer diameter of the bearing

Enter the outer diameter of the bearing.

(Unit: mm)

Outer diameter of the inner race

Enter the diameter of the cylindrical outer surface of the inner race.

This value may influence the pitch circle diameter of the bearing if the pitch circle diameter is not explicitly assigned by user.

(Unit: mm)

Inner diameter of the outer race

Enter the diameter of the cylindrical inner surface of the outer race.

This value may influence the pitch circle diameter of the bearing if the pitch circle diameter is not explicitly assigned by user.

Enter the radius of fillet on both edges at the cylindrical inner surface of the inner race.

(Unit: mm)

Fillet radius of the outer race

Enter the radius of fillet on both edges at the cylindrical outer surface of the outer race.

(Unit: mm)

Width of the inner race

In common cases both the inner and outer races of a bearing have same width. However, there are other types of bearing those have different inner and outer race width.

Version name

This is the version name of your bearing configuration.
It should be a single word without spaces.

Parameters configuration

This is the one-row configuration of your bearing.
There are two ways from this to the final FE model and simulation results:

Order a Finite Element Analysis for this configuration.
Our team will double-check the configuration, generate the FE model with the help of the Meshparts software, perform the solution and send you the simuation report within one day.
Copy and paste this configuration into your Excel table (you receive a template along with your Meshparts license for bearing modeling) of bearing configurations.
In the Meshparts software, open the bearing assembly and write the name of your new configuration in the assembly equations.
Hit the "Solve" button.

Existing configuration of parameters

You can quickly insert a complete parameter set from one of the previously configured bearings by copying the one-row configuration from an order confirmation email into this input field. The parameter values from the one-row configuration will be inserted automatically into the corresponding input fields, and you will see the updated configuration in the canvas.

Help on the Configurator for bearing simulation

How it works

Step 1. You configure your bearing
Step 2. You order a simulation report for your bearing
Step 3. We analyse your input and generate a complete structural elastic, nonlinear finite element model of the bearing
Step 4. We send you a detailed report of the simulation of your bearing

FAQ

What is the "Configurator for bearing simulation"?

The "Configurator for bearing simulation" is an interactive web page, that helps you enter geometry, material and load parameters for a specific bearing. The current parameters configuration is shown on the canvas as an axial section view through the bearing. After you change a bearing parameter, hit the return key to see the effect on the canvas. The canvas will reflect the changes.

What can I do with the "Configurator for bearing simulation"?

You can use it as parameters source for the simulation of bearings. When you are done with the configuration of your bearing, go the Step 2 (Order simulation report). The simulation report is a HTML document containing pictures, animations and graphics of various simulation results.

How is the bearing simulated?

With the help of the Meshparts® software we generate a complete structural elastic, nonlinear bearing model based on your input configuration. The simulation is performed with the help of the finite element analysis (FEA) software Ansys®.

What results does the simulation report contain?

The report includes:

Total deformation
Contact forces for each ball and each contact point (up to four contact points for each ball)
Contact pressures for each ball and each contact point.
Contact angles for each ball.
Length and width of each contact ellipse for all balls and contact points.

How much does it costs?

Unless we have a special agreement, we price one simulation report for one bearing configuration at 300.- EUR.
