Spur gear module 4 z=22 with hub

Product Description

Spur gear module 4, z=22, with hub

The spur gear module 4 with z=22 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. 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 does the operating temperature affect the choice of material for a module gear?

At high temperatures, C45E steel retains its properties much better than plastics, which can soften and lose tooth profile accuracy; in such cases steel (including stainless steel if moisture or steam is also present) is the safer choice.

How can you recognise a manufacturing defect in a gear when receiving the goods?

It is worth checking the radial runout (the gear should not "wobble" on the shaft), the uniformity of the pitch between teeth and the smoothness of the tooth surface - visible burrs, dents or uneven pitch are a signal to file a complaint.

Why is the pilot bore in a module gear often smaller than required?

A "rough" bore allows you to bore it out yourself to the exact, non-standard size of the customer's shaft - a ready-made large bore from stock would rarely match the required size perfectly.

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.

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.
