Spur gear module 1.5 z=19 with hub

Product Description

Spur gear module 1.5, z=19, with hub

The spur gear module 1.5 shown, 19 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 base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission components used in Polish industry.

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.

What does it mean when the gear "skips" teeth under load?

Most often it is a sign that the transmitted torque exceeds the tooth strength for the given module, or that the backlash is too large - in both cases continued operation leads to the teeth breaking off quickly.

What is profile shift and when is it used?

It is a slight shift of the tooth profile relative to the standard profile, used mainly with a very small number of teeth to avoid undercutting the tooth root; in typical stock applications it is not required.

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.
