Spur gear module 4 z=75 plate wheel

Product Description

Spur gear module 4, z=75, plate wheel

This module 4 gear (75 teeth, plate wheel) is used wherever reliable, maintenance-free power transmission through involute meshing is required. 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

What does the pressure angle mean in module gears and why is it usually 20°?

The pressure angle defines the inclination of the tooth flank. In European industry the standard is 20°, because it provides the optimal balance between tooth root strength and quiet gearbox operation. This avoids the phenomenon known as tooth undercutting on smaller gears.

Does the tooth shape of a module gear affect smooth running?

Yes, the ideal involute profile achieved through precise machining ensures uniform power transmission. This prevents jerking that could lead to teeth breaking off under load.

What should I do if I need a non-standard module that is not currently in the standard range?

If time is short and you need a specific size, we offer professional 3D printing from modern glass-fibre-reinforced materials. It is an outstanding, durable solution for an urgently needed spare part, for prototyping or for gears with lower loads, allowing you to restore continuity of operation very quickly.

Are module gears from different manufacturers with the same module interchangeable?

The meshing geometry (module, pressure angle) is standardised, so such gears will mesh with each other, but bore or hub dimensions may differ between manufacturers - when replacing, it is worth checking this before installation.

Where is this product used?

Used in industrial machine drives, gate and industrial door automation and as a spare part for existing module gear drives - you only need to keep the same module and pressure angle.

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.
