Abstract
<p class="1Body">This study analyzes the influence of design parameters on the dynamics of straight bevel gears by constructing a model that allows variation in the shaft angle, pressure angle, and backlash. According to the statistical analysis, the order of influence of these parameters on weight is shaft angle &gt; pressure angle &gt; backlash. When the shaft angle is 90°, the statistical results show the drive is stable and the stress fluctuation level is low. The pressure angle, on the other hand, can affect the gear’s dynamic property by influencing the driving component force on the gear and the component force on the shaft. The results for the shaft and pressure angles are used to determine the appropriate backlash. Overall, the analysis not only provides designers with an important reference but explains the dominance in the market of gear designs with a 90° shaft angle and a 20° pressure angle.</p>
Highlights
Bevel gears, primarily of spiral, hypoid, and straight types, are widely used on the power transmission of concurrent axes and alternating axes
The results provide a useful reference for straight bevel gear design
The main influence on stress and fluctuation occurs at the shaft angle and pressure angle, an appropriate backlash value should be determined based on their design and working condition
Summary
Primarily of spiral, hypoid, and straight types, are widely used on the power transmission of concurrent axes and alternating axes. The most common type of bevel gear is the straight bevel gear, which is applied to power transmissions between concurrent axes. This gear is characterized by a straight tooth whose depth decreases gradually from large to tip end. The results provide a useful reference for straight bevel gear design
