A New Method to Calculate Bending Deformation of Involute Helical Gear
The traditional method to calculate bending displacement of helical tooth is generally based on simplified tooth profile. Besides, the unbalance loading is not taken into account. To overcome this disadvantage, a new method to calculate bending deformation of helical tooth is introduced. First, gear section is divided into several copies along tooth width and each section’s moment of inertia is...

متن کاملOn Jack Phillip's Spatial Involute Gearing
This is a geometric approach to spatial involute gearing which has recently been developed by Jack Phillips (2003). After recalling Phillips' fundamental theorems and other properties, some geometric questions around this interesting type of gearing are discussed.
متن کاملInvolute of Cubic Pythagorean-Hodograph Curve
Since the mode of Pythagorean-Hodograph curve’s derivate is a polynomial, its involute should be a rational polynomial. We study the expression form of PH cubic’s involute, discovering that its control points and weights are all constructed by corresponding PH cubic’s geometry property. Moreover, we prove that cubic PH curves have neither cusp nor inflection; there are two points coincidence in...
متن کاملOptimal Selection of Addendum Modification Coefficients of Involute Cylindrical Gears
Based on the principles of equalized sliding coefficients and equalized teeth bending strength, the optimization mathematical model for calculating and allocating the addendum modification coefficients of involute cylindrical gear is firstly established. Then the measures to calculate the tooth parameters in real-time during the optimization steps are achieved. Finally, the optimization program...
