High Load Capacity: Utilizing high-strength alloy steel gears with a hardness of HRC58-62, they are suitable for heavy-duty applications in metallurgy and mining, delivering powerful torque output.
Long Life and Durability: Gears are case-hardened and precision-ground to Grade 6 (GB/T 10095-88) accuracy, resulting in a lifespan exceeding 20 years and strong corrosion resistance.
Compact and Lightweight Design: Parallel shaft layout ensures compact size and light weight, making them suitable for automation and light industrial equipment where space is limited.
High Transmission Efficiency: Single-stage efficiencies exceed 96.5%, two-stage efficiencies exceed 93%, and three-stage efficiencies exceed 90%, minimizing energy loss and supporting inputs up to 1500 rpm.
Low-Noise, Smooth Operation: Helical gear meshing reduces vibration and backlash, enabling circumferential speeds up to 20 m/s for quiet operation, making them suitable for continuous duty equipment.
Flexible and Reliable Installation: Supports horizontal or vertical mounting, bidirectional operation, and is suitable for temperatures ranging from -40°C to +50°C. Its modular design facilitates maintenance and comes with a standard 12-month warranty.
1. What is the ZY Series Cylindrical Gear Reducer used for?
It is a parallel-shaft, hardened-tooth gear reducer designed for heavy-duty applications in industries such as metallurgy, mining, cement, construction, chemical processing, transportation, and light industry. It reduces motor speed and increases torque for equipment like conveyors, mixers, and hoists.
2. What are the key models in the ZY Series?
The series includes ZDY (single-stage), ZLY (two-stage), ZSY (three-stage), and ZFY (four-stage) models, with specific types like ZSY160, ZSY315, etc., offering varied speed ratios and torque capacities for different applications.
3. What materials and treatments ensure its durability?
Gears are made from high-strength alloy steel, processed via carburizing, quenching, and precision grinding to achieve Grade 6 accuracy (GB/T 10095-88) and tooth hardness of HRC58-62, ensuring long life (up to 20+ years) and resistance to wear or corrosion.
4. What is the transmission efficiency of the ZY Series?
Efficiency varies by stage: single-stage >96.5%, two-stage >93%, three-stage >90%, and four-stage slightly lower. This high efficiency minimizes energy loss, supporting high-speed inputs up to 1500 rpm.
5. Can it operate in harsh environments?
Yes, it is designed for temperatures from -40°C to +50°C and can withstand humid or dusty conditions due to its robust construction and anti-erosion treatments. Proper lubrication is critical for extreme conditions.
6. What are the installation options?
It supports horizontal or vertical mounting and bidirectional operation, offering flexibility for various machinery layouts. Modular design simplifies installation and maintenance.
7. How is maintenance handled, and what is the warranty?
The reducer uses splash lubrication for easy maintenance, with regular oil checks recommended. Manufacturers typically provide a 12-month warranty, and 100% self-inspection ensures reliability before delivery.
