Week 8 Worm Gear Challenge

Objective: To simulate a worm gear and find the total deformation, strain and stress developed.

Materials:

For both the worm and gear, structural steel is used.

Geometry:

It consists of a worm and gear.

Connections:

1.Contact Sets:

A frictional contact is applied between worm and gear.

2. Joints:

A body to ground revolute joint is set up for both the worm and gear.

Mesh:

Nodes:12334

Elememts:5688

Analysis Setting:

For all the steps the setting remains the same. All the output controls are turned on. The non linear stabilisation is turned on with a constant 0.1.

2. Joint - Rotation:

A rotation is applied to the revolute joint of worm.

Results:

1.Total Deformation:

2.Equivalent Strain:

3.Equivalent Stress:

Max Value	Total Deformation(mm)	Equivalent Strain	Equivalent Stress(MPa)
Worm Gear	7.2559	0.0055181	922.7
