The main periods of evolution of the conjugate action law: in parallel-axes gearing

Abstract

Three fundamental laws of gearing are distinguished in the modern theory of gearing. They are listed immediately below [3]: 1. The Law of Contact between interacting tooth flanks: The first fundamental law of gearing. 2. Еру Conjugate Action Law between interacting tooth flanks: The second fundamental law of gearing. 3. The Law of Equal Base Pitches: The third fundamental law of gearing.
