AISI 8620 20CrNiMoA Steel 4 Module Helical Gears For Speed Redcuers

1) Description of Helical Gear

Helical gears are cylindrical gears with teeth that are at an angle to the axis of rotation of the gear wheel.

1) Features of the Helical Gear

Helical Gear transfer loads more somoothly than spure gear.

Helical gear can work with greater load capacity, quiter running, and higher speed capacity when compared

with spur gear.

2) Main Technical Data of Helical Gear

Pressure angle: Pressure angle is the angle of tooth drive action, or the angle between the line of froce

between meshing teeth and the tangent to the pitch circle at the point of mesh.

Typical pressure angles are 14.5° or 20°

Helix angle: Helix angle is the angle at which the gear teeth are aligned compared to the axis.
