Specifies the dimensional characteristics of the basic rack, having a constant bottom clearance. In these gear pairs the tip angle of one gear is equal to the difference between the designed shaft angle and the root angle of the mating gear. Gives profile and some notes and defines the terms basic rack and reference line.
Abstract
Overview
ISO 677:1976 - "Straight bevel gears for general engineering and heavy engineering - Basic rack" defines the dimensional characteristics and profile of the used as the reference tooth form for straight bevel gears with involute teeth. The standard is concerned with a basic rack that has a and establishes how rack dimensions scale with module or diametral pitch. It also defines the term and gives the relationship between the basic-rack profile and the cutting tools used to generate bevel teeth.
