1: Features
The H series gearboxes are parallel shaft industrial gear reducers, widely applicable to high-power and high-torque conditions. They feature high-strength cast iron housings and modular design.
The entire structure is compact and highly durable.
2: Improved operational reliability, increased transmission efficiency
3: Offer flange-type output shafts for gearboxes to meet installation requirements in confined spaces.
2: Installation Method:
The gearbox can be mounted horizontally or vertically.
Installation in other forms available upon customer request.
The motor installation is equipped with a flange, and the torque arm support is a standard accessory of the product.
Four: Gear Noise Characteristics:
Employing new design concepts, the noise characteristics of gears are improved through the following approaches:
Material for noise-absorbing boxes
Utilize oversized tooth surface 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 body
Utilizing large fans and new-style airflow hood
Select a suitable gearbox based on the lower allowable oil temperature. This will extend the oil change cycle, thereby increasing the reliability of the equipment's operation and reducing maintenance costs.
Six: Inventory
Gearboxes are designed according to modular unit structures, significantly 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 lead time
Attractive pricing/Comprehensive speed grade classification
Non-contact and wear-resistant labyrinth oil seal, designed with a flange for the output shaft for better installation of the reducer.
Fluorinated rubber seals, featuring excellent high-temperature resistance, anti-aging, and wear resistance, offer enhanced safety and extended service life in complex and harsh operating environments. The design improvements to the cooling fan and cooling tube have effectively reduced the temperature during the gear box's operation.
