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

製品写真
  • 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.

Just Touch System

Just Touch System

Tsubaki belt sprockets are genuine parts developed to bring out 100% of the capacity of high-strength, high-tensile PX belts.

Just Touch system engagement is adopted to a unique circular arc tooth contour.

This is a genuine, reliable part that not only reduces transmission loss but also prevents problems such as tooth chipping by the close contact between the belt and belt sprocket tooth profile without any gap.

Lock Belt Sprockets

Lock belt sprockets are belt sprockets with integrated keyless locking devices.

Zero backlash through friction locking. Phasing, installation, and removal are easy No retainer for along the shaft axis is required.

Can be chosen from three types according to the application: S type standard model, N type that enables easy locking with a single nut, and C type that can be easily locked with two bolts using a clamp collar.
