Spur gear module 6 z=23 with hub, C45 steel, hardened teeth

Product Description

Spur gear module 6 z=23 with hub, C45 steel, hardened teeth is a straight-toothed spur gear: module 6, 23 teeth, pressure angle 20°. It is made of C45 steel. The teeth are induction hardened to 45-55 HRC, so they withstand wear better. The hub is not hardened, so the bore can be machined to the shaft size.

The gear has a one-sided hub with a diameter of 110 mm and a pilot bore of Ø25 mm, which is machined to the shaft size and completed with a keyway or a set screw hole. The face width is 60 mm and the overall width of the gear with hub is 80 mm.

Technical data

Applications

It is used in gear trains of industrial and agricultural machinery, in conveyor and feeder drives and in workshop equipment.

Frequently asked questions

Which gear has module 6, 23 teeth and an outside diameter of 150 mm?

It is a straight-toothed spur gear, module 6, z=23: pitch diameter 138 mm, outside diameter 150 mm. The matching product in the Ozdowski range is: spur gear module 6 z=23 with hub, C45 steel, hardened teeth. The module of a measured gear can be checked by dividing the outside diameter by the number of teeth plus 2.

Which gears can this gear mesh with?

With any straight-toothed spur gear of the same module (6) and a pressure angle of 20°, and also with a module 6 rack. The number of teeth of the mating gear determines the gear ratio.

How do I calculate the centre distance of two gears?

The centre distance is half the sum of the pitch diameters: a = m × (z1 + z2) / 2. For example, two module 6 gears with 23 teeth require a centre distance of 138 mm.

Can the bore be machined to the shaft size?

Yes. The pilot bore Ø25 mm is machined to the shaft size and completed with a keyway or a set screw hole. The maximum bore diameter depends on the hub diameter (110 mm) - sufficient wall thickness must remain after machining.

Does hardening make machining the hub bore difficult?

No. Only the teeth are induction hardened (45-55 HRC); the hub remains unhardened. The bore can be machined to the shaft size and fitted with a keyway or a set screw hole.

What does the lead time depend on?

When ordering, 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 each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
