Spur gear module 3 z=33 with hub hardened

Product Description

Spur gear module 3, z=33, with hub, hardened

The spur gear module 3 shown, 33 teeth, with hub, is a basic component of module drives - it meshes with any other gear or gear rack (toothed rack) of the same module and pressure angle 20°. The tooth surface is induction hardened (45-55 HRC), so the gear better withstands high cyclic loads and operation in harsh industrial conditions.

Technical data

Frequently asked questions

How does a module gear differ from a chain sprocket?

A module gear meshes directly with another gear or gear rack, while a sprocket works with a roller chain - they have a different tooth profile and are not interchangeable, even though they look similar from a distance.

How do you set the correct centre distance between two module gears?

The centre distance is the sum of the pitch diameters of both gears divided by two (a = (Dp1+Dp2)/2); too small a distance causes seizing, and too large a distance - excessive backlash and loss of quiet running.

How does the operating temperature affect the choice of material for a module gear?

At high temperatures, C45E steel retains its properties much better than plastics, which can soften and lose tooth profile accuracy; in such cases steel (including stainless steel if moisture or steam is also present) is the safer choice.

How does the build quality of a Polish/European manufacturer reduce rolling resistance in the gearbox?

Cheap gears from unverified sources often have a rough tooth surface that acts like sandpaper, raising the temperature and the drive resistance. Our gears have a smooth working surface, which helps maintain the lubricating film and minimises energy losses.

Where is this product used?

Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.

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.
