Tungsten Carbide Gear

Tungsten carbide gear has better performance in hardness, toughness and wears resistance than other gear materials, so it can effectively ensure the working stability and extend the service life. Generally, tungsten carbide gear is composed of teeth, groove, normal plane, addendum circle, tooth root circle, the base circle and pitch circle.
Teeth: For engaging the convex portion, the raised portions generally radially aligned mating contact of teeth on each gear, the gear can operate in constant engagement;
Groove: The space between two teeth, the end surface is cylindrical or cylindrical worm gear, or a plane perpendicular to the axis of the worm gear;
End surface: The surface two ends of the gear;
Normal plane: Perpendicular to the plane of the tooth line;
Addendum circle: The circle top of the teeth;
Tooth root circle: The circle of the bottom;
The base circle: The circle forming involute, rolling only;
Pitch circle: The base circle of the end face of the gear geometry calculation.

In addition, tungsten carbide gear can be divided by the shape, the profile, the surface and the manufacturing process.
The profile: It includes tooth outline, pressure angle, tooth height. Involute gear relatively easy to manufacture, so the involute gear is absolute majority in the use of modern gear, and less cycloid gear and circular gear applications (straight, helical, herringbone, curved);
The shape: Cylindrical gear, bevel gear, non circular gear, worms;
The surface: The internal gear and the external gear;
The manufacturing process: Casting gear, cutting gear, rolling gear and sintering gear.
