Synchronous Pulleys Synchronous Pulley elements improve performance of motor-driven systems, increasing energy efficiency and reducing maintenance costs. Synchronous drive allows adjustment of speed and torque while connecting mechanically rotating components; belts and pulleys use teeth to avoid slippage and unwanted speed variations.

Synchronous Pulleys
Description: They are toothed pulleys that transmit power through positive engagement between your pulley teeth and sprocket grooves instead of friction used in standard belts. They utilize the tooth-grip basic principle where square, circular, or altered curvilinear pulley the teeth mesh with correctly timed grooves on a drive for positive power transmission. As the pulley maintains positive engagement with the generating gear sprocket, power transmission is smooth. For instance, there is no need to get worried about the pulley slipping over just how it happens with regular belt drives. Furthermore, the thin cross section of synchronous pulleys means that less energy is needed to run it. On vital drives, utilizing a synchronous pulley that does not require retensioning can help improve your systems energy efficiency. It also helps to decrease downtime. This will increase the overall creation. Another advantage of using synchronous pulleys is that they allow your system to operate under different speeds, loads, and frequent starts. However, it is important to ensure that your machine is definitely maintained at best condition for optimal performance. If installed correctly, you are confident of high mechanical performance. Synchronous pulleys can deliver as high as 98% efficiency when installed correctly. This is higher than the common V-belts that provide an average efficiency of 96%. However, it is important to appreciate that synchronous pulleys aren’t ideal for all circumstances. If your production program was designed to use the regular belts, changing to synchronous pulleys might require some adjustments. As a result, you should consider engaging a specialist before shifting to synchronous pulleys.
SYNCHRONOUS PULLEY
Ever-power’s SYNCHRONOUS pulleys are available for almost every shaft diameter with regards to number of the teeth as well regarding the profile chosen. They offer the option of non-positive or positive connections to the shaft using a clamping screw, keyway or conical clamping sleeve. MISUMI offers timing pulleys in aluminium or steel versions.
