Thermal Analysis of Helical & Spiral Gear Train
Gears are the common means of transmitting motion and power. In this project, we study the thermal analysis of helical and spiral gears transmission gearbox. We designed the 3D model gears and thermally analyzed the temperature generated at the tip of the mating gears during full load and no-load conditions. It is necessary to reduce the amount of heat generation and thereby improve the quality and performance rate.
The design and dimensioning were modeled and thermal analysis was done in SOLIDWORKS and ANSYS WORKBENCH.
SOLIDWORKS Premium 2021 SP4.1 - [Assem4 _] 2022-01-08 14-55-02_Trim.mp4Gear Design Details:
Material selected: Plain Carbon Steel C40
Input Power: 16 kW
Input Speed: 590 rpm
Output Speed: 15 rpm
Friction in contact pairs (between the gear and pinion interface): 0.16
Model kept at room temperature
Gear Design Profile
Meshed model of Pinion and Gear
Thermal Analysis Results:
Temperature Distribution in Pinion
Temperature Distribution Plot for Gear
Analysis of Initial Loading Conditions
For the selected material, it was found that the stress-induced was within the safe limit and the heat generated due to friction was 265 degrees Celsius which was exceeding the permissible limit of the standards. This can be solved by the cooling effect from oil or other lubricants by convection to reduce the temperature.
