Spatial involute gearing - a new type of skew gears
This is a geometric approach to spatial involute gearing which has recently been developed by Jack Phillips [4]. Due to Phillips' fundamental theorems helical involute gears for parallel axes (Fig. 2) serve also as tooth flanks for a uniform transmission between skew axes, and the transmission ratio is even independent of the relative position of the axes.
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...
متن کاملBending strength simulation of asymmetric involute tooth gears
In order to enhance the load capacity of gears, researchers take notice in the asymmetric tooth gears. Asymmetric gear which has higher pressure angle of back tooth aiming to improve banding strength has been analyzed (Deng, et al., 2003). Brown et al. (Brown, et al., 2010) investigate the asymmetric tooth from both point of view of bending and scuffing. Kruger et al. (Kruger et al., 2013) anal...
متن کاملUse of Non-Circular Gears in Pressing Machine Driving Systems
The paper describes a new approach in non-circular gears design, based on the mathematical description of the meshing progress. The teeth profiles are generated by numerical integration of a differential equation, which describes the contact point displacement, along the line of action, as a function of the pitch lines shape and of the pressure angle. In the typical arrangement, a pair of non-c...
متن کاملMeasuring Geometrical Parameters of Involute Spur Gears to Sub-pixel Resolution
The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...
