One: Features

The H Series Gearbox is a parallel shaft industrial gear reducer, widely applicable to high-power and high-torque applications. It features a high-strength cast iron housing and modular design.

The entire structure is compact and highly robust.

2: Improved operational reliability, increased transmission efficiency

3: Offer flange-type output shafts to meet the installation requirements in confined spaces for gearboxes.

II: Installation Method:

The gearbox can be mounted horizontally or vertically.

Installation in other forms available upon customer request.

The motor is installed with a flange, and the torque arm support is a standard configuration of the product.

Four: Gear Noise Characteristics:

Embrace new design philosophies to enhance the noise characteristics of gears through the following approaches:

Material for noise-absorbing enclosures

Utilize oversized pitch diameter contact ratio

All gears are precision ground.

Five: Gearbox Cooling

The gearbox not only boasts high transmission efficiency but also excellent heat dissipation capabilities, primarily achieved through the following methods:

Increase the surface area of the box

Utilizing large fans and new-style airflow hood

Select a gear box based on the lower maximum allowable oil temperature; this will extend the oil change cycle, thus increasing the reliability of the equipment operation and reducing maintenance costs.

Six: Inventory

The gearbox is designed according to the modular unit structure, greatly reducing the variety of parts.

Seven: Application

Belt Drive Equipment / Hoisting Equipment / Mixing Equipment / Lifting Equipment / Mobile Equipment / Papermaking Equipment / Drying Machine Equipment

Eight: Short delivery period

Attractive pricing/Comprehensive speed grading

Contactless and wear-resistant labyrinth oil seal with flange designed for the output shaft for better installation of the reducer.

Fluorinated rubber seals with excellent high-temperature resistance, anti-aging, and wear resistance, offering enhanced safety and extended lifespan in complex and harsh operating environments. Improved design of cooling fans and coils effectively reduces the temperature during gear box operation.
