1.3 Features

•

Smooth transmission, low noise: Features a high-precision worm gear meshing design, ensuring no significant vibration during transmission. Operating noise is below 75 dB, making it suitable for industrial applications with strict noise requirements and enhancing equipment operating comfort.

•

High load capacity and long service life: The housing is made of high-strength cast aluminum or cast iron, while the worm gear and worm shaft are crafted from wear-resistant alloy materials. Through precision machining and heat treatment, the unit can withstand significant radial and axial loads, effectively resisting wear during operation, extending service life, and reducing maintenance frequency.

•

Strong speed control adaptability: Based on control signals from the 8516 series speed controllers, the output speed can be precisely adjusted to achieve stepless speed regulation of power equipment. This adapts to speed requirements under various operating conditions and works in conjunction with speed control systems to achieve precise control.

•

Compact design with minimal space requirements: Featuring a modular design, the unit is over 30% smaller in volume than parallel-shaft gearboxes of equivalent torque. It is suitable for equipment installation scenarios with limited space, facilitating optimization of the overall equipment layout.

•

Easy maintenance: Excellent sealing performance effectively prevents lubricant leakage; the internal structure is rationally designed for easy disassembly and assembly. Routine maintenance requires only periodic checks of lubricant levels and wear conditions, thereby reducing operational and maintenance costs.
