Spur gear module 2.5 z=12 with hub hardened

Product Description

Spur gear module 2.5, z=12, with hub, hardened

This module 2.5 spur gear (12 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The teeth are induction hardened to 45-55 HRC, which significantly increases wear resistance and extends gear service life in heavily loaded transmissions.

Technical data

Frequently asked questions

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.

What is the module of a gear and how do you measure it correctly?

The module (m) is the basic parameter defining tooth size, i.e. the ratio of the pitch diameter to the number of teeth. The simplest way to measure it in workshop conditions is to measure the outside diameter of the gear (Dz), count the teeth (Z) and use the formula: m = Dz / (Z + 2).

Can a module gear be ordered with a number of teeth outside the standard catalogue range?

Yes, in addition to ready stock we also produce CNC gears to order with a non-standard number of teeth, and for short lead times we additionally print them using 3D technology from glass-fibre-reinforced plastics.

How does manufacturing gears on CNC machine tools eliminate gearbox noise?

Old casting methods or milling on worn machines produce irregularities in the order of tenths of a millimetre. Our CNC machining ensures a perfect tooth profile. The gears roll on each other smoothly, which results in a dramatic drop in decibels on the production floor.

Where is this product used?

Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.

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.
