1) Structural Features
a) Unique tooth shape: The tooth shape of a herringbone gear is V-shaped, consisting of two helical gears with opposite spiral directions.
When viewed from the top, each spiral groove resembles the letter ‘V’, and multiple ‘V’ shapes combine to form a herringbone pattern.
b) No axial clearance: Similar to double helical gears, but there is no clearance between the two helical surfaces,
which makes the herringbone gears more compact during transmission and able to withstand higher loads.
2) Performance Advantages
a) High load-carrying capacity: The large contact area of the teeth on helical gears allows loads to be distributed evenly across the tooth surfaces,
resulting in a high load-carrying capacity and making them suitable for applications requiring the transmission of high torque.
b) Smooth Transmission: Due to the large number of tooth pairs engaged simultaneously and the cancellation of axial forces,
helical gears exhibit minimal vibration and noise during transmission, resulting in smooth operation.
They are suitable for equipment requiring high levels of smoothness.
c) High efficiency: The tooth profile design of helical gears minimises sliding friction between teeth, resulting in relatively high transmission efficiency.
This effectively reduces energy loss and improves the energy utilisation efficiency of equipment.
