Product Info Synchronous Belts / Belt Sprockets
Tsubaki synchronous belt is a toothed belt made of rubber and is also called a toothed belt.
By engaging tooth profile provided on belt/belt sprocket (gear), rotation can be reliably transmitted without slipping like a V-belt or flat-belt that is transmitted only by friction.
By embedding glass, aramid or carbon fiber core wires inside, they have high tensile strength and are used in applications where accurate positioning and high synchronization are required.

Features of Synchronous Belts

-
Precision drive
As a mechanism of engaged-drive, synchronous belts realize precision drive with only little belt elongation.
-
Low noise drive
Compared to other power transmission elements such as gears, synchronous belts offer low-noise and smooth drive.
-
Lube-free
Synchronous belts are lube-free allowing a clean drive without spillage or contamination.
-
High-efficiency rating
Synchronous belts can transmit power efficiently with minimal energy loss.
-
High-speed drive
Synchronous belts can be operated at high-speed compared to other power ?transmission parts such as gears.
Construction
Backing
Durable and wear-resistant Chloroplene rubber (High Intensity Synthetic rubber) protects the core wires and enables long life.Cord
High-tensile glass fiber (or aramid fiber) with extremely low elongation has been used to enable high-precision transmission.Tooth rubber
Tooth rubber integrally molded with backing rubber enables high-load synchronous transmission.Tooth fabric
Wear resistance and self-lube enable smooth engagement and low noise.

Dimple
Quiet thanks to the adoption of unique dimples on the tooth ends.

Just Touch System
Just-touch system in which the teeth engage with the pulley at both the tip and bottom of the teeth enables high-precision transmission.
