2D Spur Gear Force
A 2D spur gear force represents a force that couples two gear elements. Your template-based product computes the gear force at the pitch circle, considering the pressure (tooth) angle. It then resolves the force to the appropriate forces and moments applied at the center of one gear, with the reaction force applied at the other gear, using a general force (GFORCE). For information on GFORCE, see the
Adams Solver online help.The contact formulation is based on a scaled impact force formulation (traditional).
The gear force lets you model gear interaction with backlash. Your template-based product considers the actual contact points at up to three teeth per gear. When creating the gear force, the gears are rotated automatically to ensure proper meshing of the gears. In addition to the GFORCE, your template-based product creates an INPLANE joint primitive at the idealized point of contact with its normal tangential to the pitch circle. The inplane joint primitive is only active during the initial condition
Analysis phase of a
Simulation. This will ensure that the initial conditions (displacement, velocity, and accelerations) of the gears are calculated appropriately.
This component allows you to model spur gear force, where the centers of the gears are not fixed in space (bending in shafts) and the mesh frequency is considered.
The component outputs the following results:
■total_tooth_force - Resulting force normal to the gear tooth surface.
■tooth_force_1 - Force on the first tooth of currently possible teeth in contact.
■tooth_force_2 - Force on the second tooth of currently possible teeth in contact.
■tooth_force_3 - Force on the third tooth of currently possible teeth in contact.
■torque - Resulting torque applied at the first gear. The gear force icon is positioned at the center of the first gear.
