The effect of machined wheel profile geometry on cutting force

Abstract

Abstract The mechanisms based on standard geometry gears have reached their technological limits. To meet the needs of the market, it is necessary to meet new and new, often conflicting operational requirements. At the same time, it is necessary to reduce the mass of the node and increase the maximum torque, in addition, the noise level and increase the axial load must be reduced. To achieve the increasing requirements for the operational characteristics of mechanisms gears with specially designed tooth geometry are used. A tool for cutting such gears must be specially designed and manufactured for each new gear pair, given into account its design features. The introduction of a new tool in the technological processes of machining gear profiles leads to the fact that the surface quality decreases and tool wear increases. At present, the concept of this problem is scattered and composed of the experience of individual researchers. The work reveals the dependencies connecting physical phenomena accompanying the cutting process and the geometric parameters of the profile of the bevel gear. Based on the results of the project, it is possible to calculate the optimal profile parameters based on the technological parameters of the process.
