    45° Helical Angle 2 Module Transmission Gears Precision Manufacturing

    2-module Power Skiving internal helical gears 45° helical angle

    1) Description of Internal Helical Gear

    Internal helical gears are a special type of gear with a helical tooth shape and machined on the inner surface of a cylindrical member,

    meshing with an external helical gear to achieve power transmission. Compared with spur internal gears,

    its spiral tooth design has advantages in transmission performance, load capacity, and noise control, and is widely used

    in industrial scenarios that require compact layout and efficient power transmission.

    2) Key Features of Internal Helical Gear

    a) High transmission stability
    The meshing process of the helical teeth is a gradual contact,
    with a larger contact area and the gradual transfer of load from one tooth

    to the next, reducing shock and vibration and operating noise.
    b) Strong bearing capacity
    The larger contact area and helical angle result in a more uniform distribution of axial forces, allowing internal helical gears

    to withstand higher radial and axial loads than spur internal gears of the same specification, making them suitable for high-torque scenarios.
    c) Excellent space utilization
    The internal gear structure itself saves radial space through "internal engagement" (external gears are located inside the internal gear),

    while the helical design further optimizes the axial dimensions for compact equipment .
    d) Efficiency improvements
    Smooth engagement reduces energy loss, and transmission efficiency is typically higher than that of spur gears .

    3) Applications of Internal Helical Gear

    a) Industrial gearbox: used for deceleration or speed increase transmission of metallurgical and mining equipment, transmitting high power torque.
    b) Automotive drivetrains: such as planetary gear mechanisms in automatic transmissions, utilizing internal helical gears for compact layout and high torque output.
    c) Construction machinery: power transmission between the hydraulic motor and the working device of excavators and cranes.
    d) Aerospace: Helicopter reducers, missile drive systems, and other fields that require high reliability and compactness.
