Product Info Synchronous Belts and Belt Sprockets

Tsubaki Synchronous Belts are rubber belts with teeth and are also known as toothed belts.

By meshing the teeth on the belt pulley (gear), rotation can be transmitted reliably without slipping, unlike flat belts and V-belts, which transmit power solely through friction.

By embedding glass fiber, aramid fiber, or carbon fiber core wires inside, they have high tensile strength and are used in applications that require accurate positioning and high synchronization.

Synchronous Belts Features

  • High precision operation is possible.

    The meshing transmission allows for accurate operation, and there is almost no belt stretch during operation.

  • Low noise.

    It allows for quieter and smoother operation than other transmission elements such as gears.

  • It's a clean transmission.

    No lubrication is required.

  • High efficiency.

    It can efficiently transmit power from motors and other devices, with almost no energy loss.

  • High speed operation is possible.

    Compared to other transmission elements such as gears, it is possible to operate at high speeds.

Structure

  • Backing rubber

    耐久性、耐摩耗性を向上させた、クロロプレンゴム(または高強度合成ゴム)により、
    心線を保護し長寿命を可能にしました。
  • core wire

    伸びが極めて少ない高抗張力グラスファイバー(またはアラミド繊維)を使用し、
    高精度伝動を可能にしました。
  • Tooth rubber

    背ゴムと一体成形された歯ゴムは、高負荷のかみ合い伝動を可能にしました。
  • Tooth fabric

    耐摩耗性および自己潤滑により、スムーズなかみ合いと低騒音を可能にしました。

  • dimple

    Low noise due to the effect of special dimples on the tooth tips.

  • Just Touch Method

    The just-touch method of engagement with the pulley, in which both the tooth tip and tooth root come into contact, enables high-precision transmission.

Lock Belt Sprockets Pulley

Lock Belt Sprockets is Belt Sprockets with an integrated keyless fastener.

Friction locking eliminates backlash. Phase alignment, installation and removal are easy. No need for axial locking.

Depending on the application, you can choose from three types: the standard S type, the N type that can be fastened with one nut, and the C type that can be easily fastened with two bolts using a clamp collar.
