Spur gear module 2.5 z=41 with hub

Product Description

Spur gear module 2.5, z=41, with hub

The spur gear module 2.5 with z=41 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Technical data

Frequently asked questions

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.

How do you set the correct centre distance between two module gears?

The centre distance is the sum of the pitch diameters of both gears divided by two (a = (Dp1+Dp2)/2); too small a distance causes seizing, and too large a distance - excessive backlash and loss of quiet running.

How do you calculate the outside diameter from the number of teeth and the module?

It is very simple maths, often used by maintenance departments. The formula is: Dz = m * (Z + 2). For example, for a gear with module 3 and 20 teeth, the outside diameter will be: 3 * (20 + 2) = 66 mm.

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.

Where is this product used?

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