Sprocket 12B-3 z=18 with hub

Product Description

Sprocket 12B-3 z=18, with hub

Sprocket 12B-3 (pitch 3/4" - 19.05 mm), triplex (three-strand), 18 teeth, with hub. As a European manufacturer, Ozdowski supplies the sprocket in C45E steel (EN 10083-1), in accordance with DIN 8187 / ISO 606 - a version without tooth hardening, cheaper than the hardened variant and sufficient for many typical industrial applications.

Technical data

Frequently asked questions

How do you select the number of teeth on the driving and driven sprockets to obtain the required ratio?

The ratio is calculated as the quotient of the number of teeth on the driven sprocket and the number of teeth on the driving sprocket. For example, to halve the rotational speed, the driven sprocket should have twice as many teeth as the driving sprocket - both sprockets must have the same pitch and number of strands.

How do you calculate the pitch circle diameter of a sprocket?

The pitch circle diameter (Dp) is, in simplified terms, the line along which the chain rollers roll. It is calculated using the formula: pitch divided by sine (180° / number of teeth).

In what cases are multi-strand sprockets used?

They are used to drive multi-strand chains in heavily loaded machines where there is no room for a wider sprocket with a larger pitch. Several strands distribute the load evenly, preventing premature chain breakage.

What should be used to preserve sprockets before a longer break in operation?

After cleaning with a brush and a technical cleaner, apply preservative grease or a thick, moisture-displacing spray oil to the entire surface of the sprocket. This will protect the metal against rust deposits during the break while it is stored in the hall.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
