9.4. Gearbox Tutorial (DriveTrain)

9.4.1. Getting Started

DriveTrain Toolkit can design the mechanical system composed of shaft, gear, bearing, etc. It can consider the material and dynamic properties of its parts. For shaft, it can design and analyze the shaft with the various radii using the FE Beam Element. For gear, it co-simulates with KISSsoft for more accurate and detailed result and it can be used with Involute Analytic Gear Contact for reduced simulation time with accurate result. For bearing, it also co-simulates with KISSsoft for more accurate and detailed result.

Note

FDR

Most of the time Shafts are attached with the machine elements like gear, bearing, etc. Connectors like pin, key, spline, snap ring are used to attach those elements. In RecurDyn, connections of these machine element are expressed as FDR element which is rigid element.

If you look at the center position of the FDR which is master node, you can see that the size of master node is bigger than the size of other nodes.

FDR Tolerance

When you create a FDR element, 3 nodes, center position and two end sides of FDR, are added to the existing nodes. The distance between existing node and the added FDR node can be very small. The FDR Tolerance is used to ignore the small element caused by creation of FDR.

For example, if FDR Tolerance is 0.01 and the distance between two nodes are 0.009, the added FDR Element is ignored and altered as existing node.

Note

Tooth Tolerance

In the Tolerance dialog, you set the tolerances of tooth thickness, tip diameter and root diameter. If you set the Upper / Lower value as 0, it means no tolerance in gear shape. If you set the Upper / Lower values, KISSsoft automatically calculate the appropriate value between the upper and lower limit.

In Gear Pair section, change the Center Distance value to 280 and click Calc. in the Backlash to calculate backlash.

Note

Contact Analysis
In Contact Analysis dialog, the Number of Meshing Positions determines the number of calculation following the Path of Contact between a meshing teeth pair. The Number of Slices determines the number of axial cross sections of gear pair where the Meshing Position is calculated.
For example, if you set the Number of Meshing Position as 17 and 11 as the Number of Slices, the 17 meshing positions are distributed evenly throughout the path of contact in each one of 11 slices while the surface of gear tooth contacts the tooth surface of other gear.

Note
