Helical internal gears are a type of internal gear with helical tooth surfaces located on the inside of the gear, designed to operate in conjunction with external gears. The helical tooth surfaces allow the gears to achieve smoother contact during operation.

    This combination does not exist.

    Features of Helical internal gears

    Helical internal gears mesh with external spiral gears to transmit power through tangential contact. During the rotation process, the design of the tooth profile ensures that the contact points are continuous, thus distributing the load smoothly and improving both transmission efficiency and stability.

    Operational Stability

    Helical internal gears can reduce noise and vibration during operation, providing smoother motion, making them ideal for various mechanical applications.

    Load Capacity

    Compared to traditional spiral internal gears, Helical internal gears can handle higher loads, making them suitable for heavy-duty and high-torque applications.

    High Efficiency

    The meshing efficiency of Helical internal gears is generally high, enabling more effective power transmission.

    Self-Centering Capability

    Due to the design of the helical tooth profile, internal gears can automatically adjust during operation, enhancing the centering capability of the gear system.

    Directional Change of Motion

    Helical internal gears can be used to change the direction of rotation, making them especially effective in the design of complex mechanical systems.

    Specific Application Cases


    Helical internal gears play an important role in various industrial and engineering applications due to their unique design and excellent operational characteristics. 
    Their high load capacity, smooth operation, and self-centering ability make Helical internal gears one of the essential components in internal transmission systems.
