    Self-Locking Properties in a Worm Gearbox

    Yes, worm gearboxes exhibit self-locking properties, which can be advantageous in certain applications. Self-locking refers to the ability of a mechanism to prevent the transmission of motion from the output shaft back to the input shaft when the system is at rest. Worm gearboxes inherently possess self-locking properties due to the unique design of the worm gear and worm wheel.

    The self-locking behavior arises from the angle of the helix on the worm shaft. In a properly designed worm gearbox, the helix angle of the worm is such that it creates a mechanical advantage that resists reverse motion. When the gearbox is not actively driven, the friction between the worm threads and the worm wheel teeth creates a locking effect.

    This self-lock
