A New Method to Calculate Bending Deformation of Involute Helical Gear
نویسندگان
چکیده
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 calculated. Second, the unbalance loading of helical gear is calculated and distributed. Based on these work, a general formula for bending displacement of involutes helical gear is presented. Last, accuracy of this study is proved by an example.

Comparative Study of Stress Analysis of Helical Gear Using AGMA Standards and FEM
Gearing is one of the most effective methods for transmitting power and rotary motion from the source to its application with or without change of speed or direction. The bending and surface strength of the gear tooth are considered to be one of the main contributors for the failure of the gear in a gear set. Thus, determination of stresses has become popular as an area of research on gears to ...

متن کاملSpatial 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.
