Spur gear module 6 z=20 with hub hardened

Product Description

Spur gear module 6, z=20, with hub, hardened

This module 6 spur gear (20 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. 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

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.

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.

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 module of a gear and how do you measure it correctly?

The module (m) is the basic parameter defining tooth size, i.e. the ratio of the pitch diameter to the number of teeth. The simplest way to measure it in workshop conditions is to measure the outside diameter of the gear (Dz), count the teeth (Z) and use the formula: m = Dz / (Z + 2).

Where is this product used?

Module gears of this type are used in speed reducers, machine gearboxes, CNC machine tools and in rack drives of sliding and entrance gates.
