Product Description

ZLY Series Hardened Gear Reducer all precision ground up to Grade 6 per GB/T10095

1. Introduction

The ZLY series reducer is a medium-sized hardened cylindrical gear reducer. It is one of the standard series specified in the Chinese Machinery Industry Standard (JB/T 8853-2001), representing the advanced level of universal hardened gear reducers in China. This series uses high-quality alloy steel forged gears, which are carburized, quenched (achieving a high tooth surface hardness of HRC 58-62), and all precision ground. Its design focuses on high load capacity, high transmission efficiency, and high reliability, making it a preferred power transmission device for both new equipment design and old equipment retrofitting in many industrial fields.

2. Key Parameters

  • Models: Denoted by center distance, forming a standard series. E.g., ZLY-112, ZLY-125, ZLY-140, ZLY-160, ZLY-180, ZLY-200, ZLY-224, ZLY-250, ZLY-280, ZLY-315, ZLY-355, ZLY-400, ZLY-450, ZLY-500, ZLY-560, ZLY-630, ZLY-710 (the number represents the center distance in millimeters).

  • Transmission Stages: Doubletriple, and quadruple stage reduction.

  • Ratio Range (i): Extremely wide range.

    • Double-stage: 8:1 ~ 50:1

    • Triple-stage: 31.5:1 ~ 200:1

    • Quadruple-stage: 125:1 ~ 500:1

  • Center Distance (a): Covers a complete series of sizes from 112mm to 710mm.

  • Input Power: Ranges from about 0.5kW to tens of thousands of kW.

  • Output Torque: Provides output torque from hundreds of N·m to hundreds of thousands of N·m.

  • Gear Design:

    • Tooth Profile: Involute cylindrical gears, with optimized profile modification.

    • Surface Hardness: Hardened (HRC 58-62), with a tough core, offering excellent resistance to pitting and wear.

    • Precision: High gear precision, usually up to Grade 6 per GB/T10095.

  • Mounting Position: Flexible applicability with Horizontal (W)Vertical (L), and other mounting forms.

  • Lubrication: Usually splash lubrication (natural cooling). Larger power models can be equipped with cooling devices (fans, water-cooling coils) or forced lubrication systems.

3. Product Advantages

  • Standardization & High Universality: Strict adherence to the JB/T 8853 national standard ensures unified models, dimensions, and parameters. Good interchangeability between products from different manufacturers facilitates selection, procurement, and maintenance.

  • High Load Capacity: The hardened gear design results in a compact size and light weight, while the load capacity per unit volume is much higher than that of soft-gear reducers.

  • High Transmission Efficiency: High efficiency per stage (≥98% single, ≥97% double, ≥96% triple), leading to significant energy savings.

  • Smooth Operation & Low Noise: Precision gear grinding and scientific housing structure design ensure low vibration and quiet operation.

  • Long Service Life: Excellent resistance to pitting and wear ensures a long service life with proper maintenance.

  • High Cost-Effectiveness: As a standard product, mass production leads to competitive pricing and high comprehensive economic benefits.

4. Typical Applications

The ZLY series is a truly "universal" hardened gear reducer. Its applications cover almost all industrial sectors requiring power transmission, and it is an ideal product for replacing older ZQ and ZSH series.

  • Material Handling: Belt conveyors, bucket elevators, screw conveyors, scraper conveyors.

  • Lifting & Transportation: Hoisting and travel mechanisms of overhead/gantry cranes, port ship loaders/unloaders, stackers and reclaimers.

  • Metallurgy & Mining: Auxiliary drives for steel rolling equipment, straighteners, wire drawing machines, mine hoists, crushers.

  • Building Materials & Chemicals: Ball mills, rotary kilns, agitators, extruders.

  • Light Industry & Paper: Paper machinery, printing machinery, food processing machinery.
