from Japan as main raw material. It matches with multiple auxiliary materials with
various uses. Skeleton uses the superior glass fiber cord imported from japan. Tooth
face of the belt adopts nylon 66 high spandex for protection.
Synchronous belt drive is a novel drive mode that utilizes pulley gear meshing to
transfer motive power. It has accurate synchronous drive function. It needs no
lubrication without slip differential nor pollution and with little noise. Drive efficiency
reaches to 0.98. Speed ratio range can fulfill 1:10. Allowable linear speed can attain
50m/s. Drive efficiency ranges from several hundred watts to several kilowatts. It
suits multi-axial drive. It features as fine dynamic flex resistance, good anti-cracking
properties, superior ozone-proof performanca, sound heat-resistance and wearability etc.
