Seminar on“Stress Analysis of Eccentric Gear with

Asymmetrical Profile of Teeth”

Under guidance of,Prof. V.U.Mane sir

Presented by,Sachin YadagudiRoll No- 59

Objective

stress calculated in a standard way according to available formulas is approximate because some impacts cannot be determined with sufficient accuracy.

The problem is solved for elliptical, eccentric gear with asymmetrical profile of tooth.

Inroduction

• The stress calculation of this non-standard gearing is very complex

• Comparative stress• The complicated shape of the teeth is the

determination of stress in the teeth difficult• stress examining in a section of the foot tooth

with asymmetrical profile

Bending Stress of Gearing

Gear with Asymmetrical Profile of Tooth

• Noncircular gear with variable transmission

• Module= 3.75 mm• Changing gear ratio for

analysis • Ellipse formed with the

basic parameters

Meshing of Gears

Analysis of Gears

• Mesh generated elliptical gear, speed varies in u=0.5 through u=1.0 until u=2.0 and back

• Drive wheel gear speed is constant

• Continuous changing of the gear ratio driven wheel speed is not constant
