The finite element depends on the concept utilized to evaluate the influence of thickness of gear rim by tooth bending process in less addendum great spur gears. The gears are utilized in sugar mills, cement plants, coal mills, ball mills, kilns, copper converters, grinding mills, and anode furnaces etc. The concept is improved with ANSYS Parametric Design Language (APDL) to produce 1, 3, and 5 tooth sections of a spur gear.
The finite element approach is identified in the regions of Highest Point of Single Tooth Contact (HPSTC). The 1, 3 and 5 segments are recognized by different β that is the ratio of thickness of rim of the gear. The influence of mesh can be found in the 3-D models.
The bending and equivalent stresses are achieved for various β values in many models. The gear tooth and surface of rim stresses are presented in tables with the help of Microsoft Excel and program written in APDL and plots are produced by MATLAB program. Maximum von Mises plots and maximum bending are achieved with different β values in both dimensions models.
The photoelastic method was broadly utilized since many years. The technique was tested for the stress influencing at the gear fillets. The technique has used to improve the fillet stress which includes unbalance pressure angle. It has developed by using realistic shapes in photoelastic models.
The Effect of Rim Thickness on Bending Stresses in Low Addendum Large Spur Gears conclusion made on working of meshing concept is improved with mapped meshing abilities of ANSYS to produce two and three-dimensional element concepts of the gear. The managed meshing method is used to stop great stresses at load regions and to escape various elements in the low regions and to produce the web in the locations of the gear tooth.
