Spur gear module 2 z=40 with hub stainless

Product Description

Spur gear module 2, z=40, with hub, stainless

This module 2 spur gear (40 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The material is stainless steel - a good solution where standard carbon steel would corrode, e.g. in the food industry or when operating outdoors.

Technical data

Frequently asked questions

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).

How can a module gear be secured against sliding along the shaft?

Besides a key or a clamping bush, set screws (locking screws) in the hub, thrust washers or retaining rings are also used - the choice depends on whether the transmission operates under variable axial load.

How do you choose a gear rack to match a specific module gear?

The principle is the same as when selecting two gears - the rack must have the same module as the drive gear. Remember to choose the right rack width, which should be equal to or slightly wider than the face width of the gear, in order to transmit the full torque.

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.

Where is this product used?

Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.

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.
