What primary materials are used in the KH series components?
The housing and bracket cap are constructed from heavy-duty Alloy Steel or Carbon Steel. The worm gear is made of wear-resistant Nodular Cast Iron, while key components like adjustable bolts and nuts utilize corrosion-resistant Stainless Steel.
What is the range of speed ratios available for these models?
The speed ratios range from 26:1 (for the KH-1 model) up to 100:1 (for the heavy-duty KH-8 model), allowing for precise torque and speed adjustments depending on your application requirements.
How does output torque scale across the different KH models?
Output torque starts at 280 N.M for the compact KH-1 model and increases progressively up to 5500 N.M for the largest KH-8 model, catering to both light and heavy-duty industrial operations.
What are the weight specifications for the KH gearboxes?
The units are designed with optimized weight-to-torque ratios. The lightest model (KH-1) weighs approximately 2.6 kg, whereas the high-capacity KH-8 model weighs 115 kg.
Are these gearboxes equipped with corrosion protection?
Yes, key exterior parts such as the worm shaft feature chrome plating, and fastners (bolts, nuts, adjustable bolts) are made of stainless steel to prevent rust and extend service life in harsh environments.
