Product Description

Series 3-Stage Parallel Shaft Helical Gearbox-Heavy-Duty Industrial Speed Reducer

The high-performance 3-stage parallel shaft helical gearbox engineered for continuous operation in demanding industrial environments. As a hardened tooth surface speed reducer, it features carburized and ground helical gears that deliver exceptional load-carrying capacity, low noise, and extended service life even under high shock loads. This heavy-duty industrial gear reduction unit is specifically designed for high torque helical gear reducer applications, providing reliable power transmission in cement mixing plants, mining belt conveyors, crushers, mills, and bulk material handling systems.

With its horizontal mounted industrial gearbox configuration, the ZSY offers flexible installation and easy maintenance. The cylindrical helical gear speed reducer structure ensures high efficiency (up to 96% per stage) and smooth meshing, making it ideal for continuous operation transmission gearbox requirements where downtime must be minimized. Available in multiple frame sizes and nominal ratios from 22.4:1 to 500:1, this high ratio industrial gear reducer can match various prime movers and driven equipment specifications.

For the concrete mixing plant, the gearbox for concrete mixing plant delivers stable mixing torque and withstands frequent start-stop cycles. As a reducer for mining belt conveyor, it handles heavy radial and axial loads while maintaining consistent output speed. Whether used as a gearbox for concrete mixing plant or a reducer for mining belt conveyor, the ZSY series ensures reliable performance in dusty, humid, and high-ambient-temperature conditions.

All units are manufactured with precision-machined housings, high-grade bearing supports, and advanced sealing systems to prevent oil leakage and contamination. Customized input/output shaft arrangements, cooling fans, and backstop devices are available upon request.
