Spur gear module 1.5 z=72 with hub, C45 steel

Product Description

Spur gear module 1.5 z=72 with hub, C45 steel is a straight-toothed spur gear: module 1.5, 72 teeth, pressure angle 20°. It is made of C45 steel.

The gear has a one-sided hub with a diameter of 80 mm and a pilot bore of Ø20 mm, which is machined to the shaft size and completed with a keyway or a set screw hole. The face width is 17 mm and the overall width of the gear with hub is 30 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 1.5, 72 teeth and an outside diameter of 111 mm?

It is a straight-toothed spur gear, module 1.5, z=72: pitch diameter 108 mm, outside diameter 111 mm. The matching product in the Ozdowski range is: spur gear module 1.5 z=72 with hub, C45 steel. 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 (1.5) and a pressure angle of 20°, and also with a module 1.5 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 1.5 gears with 72 teeth require a centre distance of 108 mm.

Can the bore be machined to the shaft size?

Yes. The pilot bore Ø20 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 (80 mm) - sufficient wall thickness must remain after machining.

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.
