Spur gear module 3 z=13 with hub

Product Description

Spur gear module 3, z=13, with hub

Gear module 3, z=13, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

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.

What is the module of a gear and how do you measure it correctly?

The module (m) is the basic parameter defining tooth size, i.e. the ratio of the pitch diameter to the number of teeth. The simplest way to measure it in workshop conditions is to measure the outside diameter of the gear (Dz), count the teeth (Z) and use the formula: m = Dz / (Z + 2).

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.
