Spur gear module 3 z=22 with hub, stainless steel

Product Description

Spur gear module 3 z=22 with hub, stainless steel is a straight-toothed spur gear: module 3, 22 teeth, pressure angle 20°. It is made of stainless steel, resistant to corrosion in humid environments and during washing.

The gear has a one-sided hub with a pilot bore, which is machined to the shaft size and completed with a keyway or a set screw hole.

Technical data

Applications

It is well suited to the food, beverage and pharmaceutical industries, washing equipment and anywhere the drive operates in wet conditions.

Frequently asked questions

Which gear has module 3, 22 teeth and an outside diameter of 72 mm?

It is a straight-toothed spur gear, module 3, z=22: pitch diameter 66 mm, outside diameter 72 mm. The matching product in the Ozdowski range is: spur gear module 3 z=22 with hub, stainless 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 (3) and a pressure angle of 20°, and also with a module 3 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 3 gears with 22 teeth require a centre distance of 66 mm.

Can the bore be machined to the shaft size?

Yes. The pilot bore 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 - sufficient wall thickness must remain after machining.

Does a stainless steel gear need lubrication?

Yes. Stainless steel does not rust, but lubrication reduces friction and tooth wear. In food applications, use a lubricant approved for food contact.

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.
