Spur gear module 1 z=41 with hub

Product Description

Spur gear module 1, z=41, with hub

The spur gear module 1 shown, 41 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 gear is made of C45E steel (EN 10083-1); the involute tooth profile and 20° pressure angle ensure smooth, quiet meshing with gears or racks of the same module.

Technical data

Frequently asked questions

Can a module gear be painted or lacquered?

Yes, the external surfaces (sides, circumference) can be protected with lacquer, but the teeth and the mounting bore should remain clean, because the coating would change their actual dimensions and disrupt meshing with the other gear.

How can you check whether two module gears will mesh with each other?

There is one absolute condition: both gears must have exactly the same module (e.g. m=2) and the same pressure angle (standard 20°). If the modules differ by even a fraction of a millimetre, the teeth will start to shear and the gearbox will be destroyed.

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.

What does it mean when the gear "skips" teeth under load?

Most often it is a sign that the transmitted torque exceeds the tooth strength for the given module, or that the backlash is too large - in both cases continued operation leads to the teeth breaking off quickly.

Where is this product used?

It performs well in power transmission systems in machine tools, production lines and sliding gates, where it works together with a gear rack of the same module.

When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
