A herringbone gear, a specific type of double helical gear, is a special type of gear that is a side-to-side (not face-to-face) combination of two helical gears of opposite hands.
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 ). Unlike helical gears, herringbone gears do not produce an additional axial load.
Herringbone gears mate via the use of smooth, precisely manufactured V-shaped teeth. Like helical gears multiple teeth are engaged during rotation, distributing the work load and offering quiet operation. However, due to their tooth structure, herringbone gears nullify the axial thrust typical of helical gears.
Where the oppositely angled teeth meet in the middle of a herringbone gear, the alignment may be such that tooth tip meets tooth tip, or the alignment may be staggered, so that tooth tip meets tooth trough. The latter alignment is the unique defining characteristic of a Wuest type herringbone gear, named after its inventor.
What is the application of herringbone gear?
Applications of Herringbone gear include transmission of high torque, heavy machinery, gas turbines, heavy-duty vehicles, torque gearboxes, etc.
How do you make herringbone gear?
An effective cutting process for a herringbone gear typically involves hobbing, milling, and shaping, though these methods depend largely on whether or not a gap is required between the two helixes or if the herringbone is to be continuous. When cutting herringbone teeth, rotary cutters and hobs are typically used.
How are herringbone gears cut?
In double helical gear, a small gap is maintained by cutting a groove between two identical helical gears with opposite hands of helix. In herringbone gears, no such gap is provided between two identical helical gears with opposite hands of helix.
What are herringbone gears used for?
Gears and Gearboxes The double-helical gear, also referred to as the herringbone gear (Figure 39.8), is used for transmitting power between parallel shafts. It was developed to overcome the disadvantage of the high-end thrust that is present with single-helical gears.
What are the application of gears?
This type of gear is used for a wide range of speed ratios in a variety of mechanical applications, such as clocks, pumps, watering systems, power plant machinery, material handling equipment, and clothes washing and drying machines.
What are the applications of helical gear?
Their advantage over the helical gears is that the side-thrust of one half is balanced by that of the other half. This means that herringbone gears can be used in torque gearboxes without requiring a substantial thrust bearing.
What are the advantages of herringbone gear?
The herringbone gear consists of two sets of gear teeth on the same gear, one right hand and one left hand. Having both hands of gear teeth causes the thrust of one set to cancel out the thrust of the other. Thus, another advantage of this gear type is quiet, smooth operation at higher speeds.
What are the advantages and disadvantages of gears?
Helical gears typically have a higher manufacturing cost compared to spur gears. Helical gears generate a large amount of thrust force due to the helix angle which requires the use of thrust bearings to absorb and support this force. Higher friction due to the sliding action requires the use of lubricants.
What are the advantages and disadvantages of helical gear?
Their advantage over the helical gears is that the side-thrust of one half is balanced by that of the other half. This means that herringbone gears can be used in torque gearboxes without requiring a substantial thrust bearing.
What is the advantage of using herringbone gears?
Advantages of Herringbone gear Herringbone gears operate quietly. Herringbone gears offer smooth power transmission. Due to the V shape, the axial thrust as produced in helical gears is canceled out.
Are herringbone gears better?
Compared with single-helical gears, the herringbone gears have significant advantages of higher load carrying capacity, lager total contact ratio and lower axial force. Therefore, the herringbone planetary gear train (HPGT) is also applied to heavy machinery such as coal cutter, aerospace engine, etc.
What are the disadvantages of gears?
In herringbone gears transmission, the pinion generally adopts the axial floating installation through the axial movement to realize the balance of axial force at both ends, which is called the load-sharing phenomenon.
