Frequently asked questions
Which gear has module 4, 20 teeth and an outside diameter of 88 mm?
It is a straight-toothed spur gear, module 4, z=20: pitch diameter 80 mm, outside diameter 88 mm. The matching product in the Ozdowski range is: spur gear module 4 z=20 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 (4) and a pressure angle of 20°, and also with a module 4 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 4 gears with 20 teeth require a centre distance of 80 mm.
Can the bore be machined to the shaft size?
Yes. The pilot bore Ø15 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 (60 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.
