Spur gear module 3 z=43 with hub hardened

Product Description

Spur gear module 3, z=43, with hub, hardened

Gear module 3, z=43, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). 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

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.

How do you measure a worn tooth to choose the right replacement?

It is best to measure the outside diameter (Dz) and count the teeth (Z), and calculate the module from the formula m = Dz / (Z+2); it is also worth measuring the bore diameter so that the replacement fits the same shaft without additional machining.

Do you make module gears to special order?

Yes. In addition to ready-made gears from our warehouse, we can manufacture non-standard CNC gears based on your technical drawing. And if the machine is at a standstill and time matters to you, we will produce it using 3D printing from glass-fibre-reinforced materials.

How can you recognise a manufacturing defect in a gear when receiving the goods?

It is worth checking the radial runout (the gear should not "wobble" on the shaft), the uniformity of the pitch between teeth and the smoothness of the tooth surface - visible burrs, dents or uneven pitch are a signal to file a complaint.

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.
