Product Description
Spur gear module 1, z=40, with hub
The spur gear module 1 shown, 40 teeth, with hub, is a basic component of module drives - it meshes with any other gear or gear rack (toothed rack) of the same module and pressure angle 20°. The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Frequently asked questions
What does the pressure angle mean in module gears and why is it usually 20°?
The pressure angle defines the inclination of the tooth flank. In European industry the standard is 20°, because it provides the optimal balance between tooth root strength and quiet gearbox operation. This avoids the phenomenon known as tooth undercutting on smaller gears.
Does the tooth shape of a module gear affect smooth running?
Yes, the ideal involute profile achieved through precise machining ensures uniform power transmission. This prevents jerking that could lead to teeth breaking off under load.
How should gears be stored correctly before installation?
Preferably in a dry room, protected against moisture and dust, with a light layer of preservative oil on the teeth and bore - especially important for C45E carbon steel, which can start to corrode without protection.
In which applications do helical module gears perform well?
Helical teeth ensure smoother engagement, which drastically reduces noise and vibration at high rotational speeds. They are used in precision speed reducers and machine tools, bearing in mind, however, the need to use thrust bearings (absorbing axial forces).
Where is this product used?
Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
