ZL/ZLH/ZLSH Series Vertical Mount Helical Gear Reducers vertical mount vertical output shaft

1. Product Introduction

The ZL, ZLH, and ZLSH series are vertical mount helical gear reducers. They are variants designed for applications requiring a vertical output shaft, based on the horizontal reducers (like ZSY, ZDZ). The core gear drive components (gear material, processing technology) are identical to their horizontal counterparts.

• ZL: Stands for Vertical mount, Medium-hardened helical gear reducer (counterpart to ZDZ).

• ZLH: Stands for Vertical mount, Hardened helical gear reducer (counterpart to ZSY). "H" stands for Hardened.

• ZLSH: Stands for Vertical mount, Three-stage Hardened helical gear reducer. "S" stands for Three-stage.

The housing of this series is designed for vertical orientation, typically with a base flange for mounting onto a foundation or equipment, with the output shaft pointing vertically downward (or upward).

2. Key Advantages & Features

• Designed for Vertical Drives: Perfectly solves the layout challenges of equipment requiring vertical power transmission. Compact structure saves space.

• Inherits Core Gear Advantages:

  • ZLH/ZLSH Series: Inherit all advantages of hardened and ground gears: high load capacity, high efficiency, long service life, low noise.

  • ZL Series: Inherit advantages of medium-hardened gears: high cost-effectiveness, good load capacity.

• High Sealing Requirements: The vertical structure demands superior sealing design for input and output shafts. High-performance seals are usually employed to effectively prevent lubricant leakage.

• Easy Installation: Mounting via flange and locating spigot ensures easy alignment and a solid connection.

• Multiple Configurations: Often available with different mounting orientations (e.g., output shaft up or down), different shaft ends (solid shaft, hollow shaft, with shrink disk, etc.).

3. Main Technical Parameters

• Center Distance (a): Same as the corresponding horizontal series. E.g., ZLH range matches ZSY (160mm - 800mm), ZL matches ZDZ.

• Ratio (i): Same as the corresponding horizontal series. Single-stage (ZLH) approx. 1.25-6.3, Three-stage (ZLSH) approx. 16-100 (consult manufacturer's catalog).

• Power (P): Same range as the corresponding horizontal series, covering from kW to thousands of kW.

• Output Torque (T): Same range as the corresponding horizontal series, from kNm to hundreds of kNm.

• Mounting Configuration: Vertical flange mount. Output shaft direction is typically vertically downward (default) or upward.

4. Typical Applications

This series is the core component of any equipment requiring vertical power transmission, most commonly found in:

• Mixing Equipment: Various agitators and reactors in chemical, food, and pharmaceutical industries (This is the most classic application).

• Lifting Equipment: Bucket elevators.

• Building Material Machinery: Vertical mills, mixing plants.

• Environmental Protection Equipment: Thickeners, scrapers (for sedimentation tanks in wastewater treatment).

• Metallurgy & Mining: Vertical pumps, mixers.
