Spur gear module 2.5 z=12 with hub

Product Description

Spur gear module 2.5, z=12, with hub

The spur gear module 2.5 with z=12 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. 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

Why is precise machining of module gears crucial for drive service life?

A precisely cut tooth involute guarantees that the gears roll on each other without micro-impacts or slippage. This reduces friction lowers the operating temperature and dramatically extends the service life of the entire gearbox.

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.

Can gears with different modules be combined in one gearbox?

Absolutely not. Teeth of different modules differ in size and pitch. Any attempt to mesh them will end in the drive jamming or the teeth breaking off immediately on the first revolution of the shaft.

Do straight-tooth module gears have a specific mounting direction?

No, a straight-tooth gear is symmetrical and can be mounted either way round; direction only matters with helical teeth, where the helix angle must match the mating gear.

Where is this product used?

Used in industrial machine drives, gate and industrial door automation and as a spare part for existing module gear drives - you only need to keep the same module and pressure angle.
