Spur gear module 2 z=20 with hub hardened

Product Description

Spur gear module 2, z=20, with hub, hardened

The spur gear module 2 shown, 20 teeth, with hub, is a basic component of module drives - it meshes with any other gear or gear rack (toothed rack) of the same module and pressure angle 20°. Made of C45E steel (EN 10083-1) with induction-hardened teeth (45-55 HRC) - a variant intended for the most intensively used drives.

Technical data

Frequently asked questions

How does manufacturing gears on CNC machine tools eliminate gearbox noise?

Old casting methods or milling on worn machines produce irregularities in the order of tenths of a millimetre. Our CNC machining ensures a perfect tooth profile. The gears roll on each other smoothly, which results in a dramatic drop in decibels on the production floor.

What is the difference between a gear with hub (PM) and a plate wheel (CM), and when should you choose which?

The hub extends the part axially and makes mounting on the shaft easier (more room for a key or a clamping ring), while the plate wheel is flat and lighter - it is chosen when the design already has its own bearing arrangement/mounting and the gear only has to transmit the meshing.

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.

Can a module gear be painted or lacquered?

Yes, the external surfaces (sides, circumference) can be protected with lacquer, but the teeth and the mounting bore should remain clean, because the coating would change their actual dimensions and disrupt meshing with the other gear.

Where is this product used?

It performs well in power transmission systems in machine tools, production lines and sliding gates, where it works together with a gear rack of the same module.

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.
