Description:

The following models will demonstrate and explain, for which input options the bearing reaction forces are not expected, and when reaction forces can be expected.

A detailed explanation can be found in the report of the corresponding model.  

• Option 1: pure torque applied with moment boundary (moment around Z axis)
• Option 2: pure torque modelled with 2 forces
• Option 3: torque applied with force at an offset
• Option 4: torque applied with a (spur) gear with a gearforce

• Option 5: torque applied on a input shaft of a gearbox (2 shafts connected with a gear set) (only SimPro Expert)

SimPro Expert models:

• DGBB-CRB - torque on shaft - different options.spe

SimPro Quick models:

• DGBB-CRB - torque on shaft 1 - with moment boundary.spq
• DGBB-CRB - torque on shaft 2 - moment applied with 2 forces.spq
• DGBB-CRB - torque on shaft 3 - moment applied with 1 force.spq
• DGBB-CRB - torque on shaft 4 - gear with gearforce.spq
