Foreword

GB/T 3374 "gear Terms and Definitions" includes the following two parts. --- Part 1. geometry defined; --- Part 2. worm gear geometry definition. This section GB/T 23374 Part of. This part identical with ISO 1122-2.1999 "gear Terms and definitions - Part 2. worm gear geometry definition" (in English). This section is equivalent translation ISO 1122-2.1999. For ease of use, this section made the following editorial changes. --- Increase the "scope" of the chapter number, after the reg number sequence row; --- Remove the foreword and introduction of ISO 1122-2; --- Increased Chinese index.
