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.

Synchronous Belt / Belt Sprocket Products List

Synchronous belt

Tsubaki's synchronus belt adopts a rational circular tooth profile based on elaborate engagement theory. PX Belts that realize dramatic better performance and their water proof type, Ultra PX Belts with improved configuration material, Long unconnected open-ended belts that are ideal for reciprocating motion, and Shinayaka 530 type that generate minimal rubber debris are available.

Ultra PX Belt line-up includes HC type which has more than double the transmission capacity of PX Belt, HY type which has a hybrid core of carbon and glass for dramatically increased strength and durability, and Oil proof type which has the same transmission capacity as HC type but can be used even in an atmosphere exposed to oil and water.

Ultra PX Belt  HC Type

Model No.  BG□□□UP□M□□-HC
