Spur gear module 3 z=57 with hub

Product Description

Spur gear module 3, z=57, with hub

This module 3 spur gear (57 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. 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

Does a module gear require constant lubrication?

Enclosed gears (in speed reducers) run in oil or grease, while open systems (gear + rack) require periodic manual lubrication - without it, friction and tooth wear increase many times faster.

How can wear of the gears in a module gearbox be diagnosed?

Wear is easiest to spot from a change in the tooth profile - it becomes sharp at the tip, and the backlash increases dramatically, which shows up as loud knocking when the machine changes its direction of rotation.

How do you mount a module gear using clamping rings?

These rings are slid between the plain shaft and the plain bore of the gear. When the screws are tightened, the ring expands and locks the gear with a force many times greater than a traditional key. This is the ideal solution for module gears operating with changing direction of rotation (no backlash at the key).

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.

Where is this product used?

Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
