Spur gear module 5 z=30 with hub hardened

Product Description

Spur gear module 5, z=30, with hub, hardened

The spur gear module 5 with z=30 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. The tooth surface is induction hardened (45-55 HRC), so the gear better withstands high cyclic loads and operation in harsh industrial conditions.

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.

Why is precise machining of module gears crucial for drive service life?

A precisely cut tooth involute guarantees that the gears roll on each other without micro-impacts or slippage. This reduces friction lowers the operating temperature and dramatically extends the service life of the entire gearbox.

Do you make module gears to special order?

Yes. In addition to ready-made gears from our warehouse, we can manufacture non-standard CNC gears based on your technical drawing. And if the machine is at a standstill and time matters to you, we will produce it using 3D printing from glass-fibre-reinforced materials.

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.
