Analysis of Modification of Spur Gear Profile

Abstract

Abstract:The article presents an analysis of the modification of the toothing of spur gears. The aim of the modification of the profile on the tooth tip is to compensate for the tooth deflection under loading and to improve the conditions of gear operation. Cases of longitudinal toothing modification of a convex-convex (Cv-Cv type) tooth are described, where the tooth is biconvex and the gear teeth are convex-concave (Cv-Cc type). The conditions of mating of modified gears have been analyzed. A method of machining gears by the step-by-step method has been proposed, which can be used in unit machining of large-module gears with an arbitrary profile modification system.

Tooth contact analysis of the effect of the addendum modification coefficient of helical gears having modified teeth

“…Based on the references' recommendations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] we have created a computer software [20] with which the necessary geometric parameters could be determined (Table 1). This program can calculate the profile curves of the elements as well [20].…”

“…Many publications have been collected by great researchers which are related to this designing and connection analysis topic [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The researchers developed model for evaluating the load distribution of helical gears considering tooth modifications [6].…”
