Custom Herringbone Gear Double Helical Gear Castings And Forgings For Mining Machinery

1.Herringbone Gear Introduction | Castings and Forgings

Helical gears generate axial thrust on the shaft during operation. This axial force increases bearing load and accelerates wear of transmission components. To eliminate this force, a gear is designed with two sets of helical teeth in symmetrical and opposite directions. It looks like the Chinese character "人", hence the name herringbone gear, also known as double helical gear.

Herringbone gears have a complex structure and relatively complicated machining process. They can be manufactured by the generating method. However, hobbing has limitations and cannot process all types of herringbone gears. Milling is commonly adopted for large-size herringbone gears with high machining difficulty. We support custom production of castings and forgings, suitable for heavy-load, high-impact and continuous-operation mining working conditions.

3.Advantages of Cast & Forged Herringbone Gear

(1) Herringbone gears feature a high contact ratio. At least two teeth are engaged at any time, bringing excellent impact resistance.

(2) The meshing process of herringbone cylindrical gear teeth is gradual. The load on the tooth rises slowly from small to peak, then drops gradually. It delivers high load capacity and smooth transmission with low vibration and noise, ideal for continuous heavy-duty mining operation.

(3) The helical angles of teeth on both symmetrical sides of the herringbone gear are opposite. Axial forces generated during rotation cancel each other out, resulting in little or no net axial thrust. It reduces bearing load and extends the service life of the whole transmission assembly.
