Week 8 Worm Gear Challenge

WORM GEAR

AIM:

TO SIMULATE AND ANALYSIS FOR THE WORM GEAR AND TO FIND THE STRESS AND STRAIN VALUES ACCORDING TO THE GIVEN CONDITION.

MODEL:

THE MODEL CONSISTS OF A WORM AND A GEAR. HERE WE MADE THE GEAR SPLITTED TO HALF ACCORDING TO THE GIVEN CONDITION .

MATERIAL:

THE MATERIAL USED HERE IS THE STRUCTURAL STEEL FOR BOTH THE WORM AND GEAR.

CONNECTIONS:

THE CONNECTIONS ARE MADE WITH THE DEFAULT CONTACTS AND THE TARGET BODIES HAS BEEN INCREASED TO THE OTHER END OF THE GEAR.

CONTACTS:

THE CONTACTS ARE MADE BETWEEN THE WORM AND THE GEAR WITH THE FACES WHICH ARE AT THE MATING SURFACES. THE BEHAVIOUR OF THE CONTACTS IS SYMMETRIC AND THE FORMULATION IS LEFT AS PROGRAM CONTROLLED,

JOINTS:

THE REVOLUTE JOINTS ARE USED TO SUPPORT THE SIMULATION, HERE WE ARE ASSIGNING TWO REVOLUTE JOINTS TO SUPPORT THE SIMULATION.

MESH:

HERE WE ARE USING GRID DEPENDENCY METHOD TO CREATE A MESH TO THE MODELS WITH THE DEFAULT MESH SIZE.

ANALYSIS SETTINGS:

THE ANALYSIS IS CARRIED OUT IN 15 STEPS AND THE AUTO TIMING STEPS IS KEPT ON AND THE TYPE OF SOLVER IS KEPT AS PROGRAM CONTROLLED, LARGE DEFLECTION IS KEPT INTO ON AND THE WEAK SPRINGS IS SET AS PROGRAM CONTROLLED.

JOINT LOAD:

THE JOINT LOAD IS GIVEN TO THE REVOLUTE JOINT WHICH IS ALLOTED FOR THE WORM, WITH THE ROTATION OF 50 DEGREES FOR EACH STEPS.

CASE 1:

• TOTAL DEFORMATION:

• EQUIVALENT STRESS (VON- MISES):

• EQUIVALENT STRAIN (VON-MISSES):

• FORCE CONVERGENCE:

CONCLUSION:

THUS, FROM THE ABOVE SIMULATION WE COME TO CONCLUDE THAT, THE STRESS GENERATED ON THE GEAR WITH HALF PART TO THE WORM IS NEARLY 358.8MPa.
