TSUBAKI DRIVE CHAINS & SPROCKETS

Leonardo da Vinci, founder of the roller chain (1452-1519) Leonardo da Vinci, the genius of the Renaissance, devised the prototype of a roller chain that today is widely used as a drive chain. His foresight and advanced ideas are revealed in his notebooks, which contain sketches of an object that looks remarkably like a modern chain. The photo shows a portrait of da Vinci, made entirely out of link plates, on display in the main lobby of Tsubakimoto Chain’s Kyotanabe Plant.

The following table compares roller chains to other power transmission mechanisms such as toothed belts, V-belts and gears. Generally speaking, roller chains are often used in economical power transmission suited to low speed and high loads. However, it is also possible to use chain in high-speed applications such as camshaft drives for automobiles. Transmission Mechanism ©Excellent OGood AFair xPoor Features and Precautions of Roller Chain Transmissions ■ Features 1. Accommodate large speed reductions/increases (usually up to 1:7). 2. Chains can accommodate long shaft center distances...
