Spur gear module 1.5 z=21 with hub

Product Description

Spur gear module 1.5, z=21, with hub

Gear module 1.5, z=21, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Technical data

Frequently asked questions

In which applications do helical module gears perform well?

Helical teeth ensure smoother engagement, which drastically reduces noise and vibration at high rotational speeds. They are used in precision speed reducers and machine tools, bearing in mind, however, the need to use thrust bearings (absorbing axial forces).

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.

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.

What is backlash and why does it matter?

It is a small gap between mating teeth, necessary for lubrication and thermal tolerance; too little backlash leads to seizing and overheating, while too much leads to jerking and faster tooth wear.

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.
