A herringbone gear, a specific type of double helical gear, [1] is a side-to-side, rather than face-to-face, combination of two helical gears of opposite hands. [2] From the top, each helical groove of this gear looks like the letter V, and many together form a herringbone pattern (resembling the bones of a fish such as a herring ).
29 wrz 2024 · Double helical gears are an advanced type of gear system that improve on the design and functionality of single helical gears. Recognized by their unique “V” shape, these gears are commonly used in industrial applications requiring high precision, load capacity, and efficiency.
Double helical gears (Herringbone gears) – Gear Terminology. A combination of left-handed and right-handed helical gears with the same twist angle is called a double helical gear. Double helical gears transmit rotational motion between two parallel shafts.
Herringbone gears, also called double helical gears, are gear sets designed to transmit power through parallel or, less commonly, perpendicular axes. The unique tooth structure of a herringbone gear consists of two adjoining, opposite helixes that appear in the shape of the letter 'V'.
Double-helical gears find wide application in both high-speed and low-speed drives, including compressor speed increasers, wind turbine speed increasers, gas turbine speed reducers, hydroelectric epicyclic drives, and marine propulsion drives.
Double helical gears are designed to counteract the axial thrust forces by having two sets of teeth arranged in opposite directions with the same helix angle. This design effectively cancels out the axial forces, preventing them from being transferred to the bearings.
10 wrz 2018 · Double helical gears (herringbone gears) are characterized by a symmetric arrangement of two identical gear teeth with exactly opposite helix angles. As a result of this symmetry, the axial forces in the gearbox negate each another.
