double helical gear

1.A herringbone gear, a special type of double helical gear, is a special type of gear that is a side-by-side (not face-to-face) combination of two helical gears in opposite directions. Viewed from the top, each of the gear's spiral grooves looks like the letter V, and many of the spiral grooves together form a herringbone pattern. Unlike helical gears, herringbone gears do not create additional axial loads. Like helical gears, they have the advantage of delivering power smoothly because more than two teeth are in mesh at any one time. Their advantage over helical gears is that half of the side thrust is balanced by the other half of the side thrust. This means that herringbone gears can be used in torque gearboxes without the need for extensive thrust bearings. The herringbone gear was therefore an important step in the introduction of steam turbines for ship propulsion. Precision herringbone gears are more difficult to manufacture and therefore more expensive than equivalent spur or helical gears, so they are often used in heavy machinery. 2.Our company mainly produces non-standard mechanical products such as rotary bearings, gear rings, and shafts, which can be customized according to customer requirements. Gear shafts can produce structures such as straight teeth, helical teeth, and herringbone teeth. Rotary bearings have external teeth, internal teeth, and no teeth. We have cooperated with many new and old customers both domestically and internationally,The factory is fully equipped with professional workers and technical teams, and a complete sales team provides one-on-one service in terms of service. and we believe we welcome inquiries.

1.A combination of left and right helical gears with the same helix angle is called a double helical gear, which transmits rotational motion between parallel axes. 2.Double helical gears and herringbone gears are the same type of gear, but those with grooves between the left and right helical teeth are called double helical gears, those without grooves

1.Herringbone gears combine the advantages of helical gears (high load capacity) and spur gears (no axial force). 2.Herringbone gears can transmit high torque due to their relatively long tooth length (due to the inclination). However, the complex and therefore expensive production of this gear type is limited to special applications. (e.g. for large transfers)
