Frequently Asked Questions
What materials are used for the main body and housing of the KH series worm gear operator?
The housing and bracket cap of the KH series are constructed from high-durability Alloy Steel or Carbon Steel, ensuring excellent structural integrity and pressure resistance under heavy-duty operations.
What is the maximum output torque range offered by this product series?
The output torque ranges from 280 N.M for the compact KH-1 model up to a maximum of 5500 N.M for the largest KH-8 model, making it suitable for various valve sizes and mechanical applications.
What are the speed ratios available for the KH series worm gearboxes?
The speed ratios are designed to match the torque capacity of each model, starting from 26:1 (KH-1) up to 100:1 (KH-8), allowing for smooth manual operation with reduced input force.
How does the handwheel diameter scale with different gearbox models?
The handwheel diameter scales proportionally with the output torque requirements, ranging from 180mm for the KH-1 model up to 600mm for the KH-7 and KH-8 models to ensure comfortable manual operation.
Are the internal components rust-resistant?
Yes, critical components like the worm shaft are chrome-plated carbon steel, and key fasteners (adjustable bolts, nuts, and bolts) are made of high-grade stainless steel to prevent corrosion and extend service life.
