32.3.1.3. Constraint Bearing
A Constraint bearing is defined between two bodies. The created position types are five:
Engine Block & Shaft Main (EB_SM)
Shaft Pin & Connecting Rod (SP_CR)
Connecting Rod & Piston Pin (CR_PP)
Piston Pin & PisTon (PP_PT)
Engine Block & Balancing Shaft (EB_BS)
32.3.1.3.1. Modeling Options
Click the Constraint icon of the Crank Connector group in the Crank tab. The user can see the Crank Component Bearing – Constraint Bearing dialog box.
The user can choose the following types in Component Type and select the position where the constraint bearing is created in Component Index.
Click OK
32.3.1.3.2. Properties
Click the right mouse button on the constraint bearing component to choose Properties of constraint bearing. The user can modify the property of a constraint bearing in following dialog box.
Type: Spherical Joint, Cylindrical Joint and Revolute Joint Type.
The user can refer the following table for each constraint bearing.
