In this section we introduce the basic parts of Spur Gears (Cylindrical gears) and dimensional calculations. The size of gears is determined in accordance with the reference diameter (d) and determined by these other factors; the base circle, Pitch, Tooth Thickness, Tooth Depth, Addendum and Dedendum.

2023年12月29日 · Following are the gear terminology and gear terms used in the description of gears: 1. Pitch circle. Pich circle is the imaginary circle that rolls without slipping with a pitch circle of a mating gear. 2. Pitch Circle Diameter. The pitch circle diameter is the diameter of the pitch circle. It is also known as pitch diameter. 3.

Engineers use the following basic gear terminology while working on gears. It is the length of the gear teeth in the axial direction. It is the circle from where generate the involute teeth profile. Root Diameter is the gear diameter at the root circle or bottom teeth. It is the imaginary circle on a gear where mating gears meet with each other.

Line of Action: That line along which the point of contact between gear teeth travels, between the first point of contact and the last. Module: Ratio of Pitch Diameter to the number of teeth. Pitch Circle: The circle, the radius of which is equal to the distance from the …

Base Circle - Gear Nomenclature. Many gears have tooth forms made up of involute curves called involute tooth forms. The circle that serves as the basis for drawing the involute curve is the base circle (d b) which size is determined by the pressure angle (α) and the pitch circle diameter (d ). …

2020年5月3日 · Novice gear designed should focus on learning basic principles, theory, and formulas. Eventually overall picture of gear applications, practice experience, and manufacturing knowledge into focus.

The distance between a point of a tooth to the same point of the adjacent tooth, measured along circumference of the pitch circle is known as circular pitch. It is plays measure role in gear meshing. Two gears will mesh together correctly if and only they have same circular pitch.

Gear Terminology is a page to learn gear related technical nomenclature for all machine designers. This is a part of KHK's "Introduction to Gears". TEL : +81 48 254 1744

2024年6月25日 · Pitch diameter is the diameter of a theoretical pitch circle around which the gear teeth are designed. Pitch diameter is the main reference measurement for gear size in gear calculations, and also helps find the number of teeth in a gear. Pitch circle affects the gear’s rotational speed and torque.
