Spur gear module 4 z=23 with hub hardened

Product Description

Spur gear module 4, z=23, with hub, hardened

The spur gear module 4 with z=23 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. The teeth are induction hardened to 45-55 HRC, which significantly increases wear resistance and extends gear service life in heavily loaded transmissions.

Technical data

Frequently asked questions

Do straight-tooth module gears have a specific mounting direction?

No, a straight-tooth gear is symmetrical and can be mounted either way round; direction only matters with helical teeth, where the helix angle must match the mating gear.

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.

Does a higher number of teeth (z) with the same module mean a stronger gear?

Not directly - tooth strength depends mainly on the module and face width, not on the number of teeth; a larger z with the same module simply gives a larger gear diameter and a higher ratio relative to the mating gear.

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.

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.
