Product Description

The planet gear carrier and output end adopt an integrated double-supported structure design to ensure maximum torsional rigidity, toughness, and rotational accuracy.
The planet gear adopts a full needle roller design to increase the contact area and improve the structural rigidity and output torque.
The gear uses low carbon steel carburized and quenched to achieve a surface hardness of HRC62 to obtain the best wear resistance and impact toughness.
The gear profile is designed with assistance from imported software to obtain the best possible design, thereby reducing noise.
The connection between the input end and the motor shaft adopts a special clamping method to achieve maximum clamping force and zero backlash power transmission.
