Spur gear module 4 z=34 with hub

Product Description

Spur gear module 4, z=34, with hub

The module 4 spur gear z=34 with hub is a precision gear transmission component designed to transmit high torques at a constant ratio. The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Technical data

Frequently asked questions

Can I buy ready-made modules with drilled mounting holes at ozdowski.pl?

As standard, we supply gears and racks with a smaller pilot bore, which gives you complete freedom in adapting them to your design. You can drill the holes yourself, tap them for set screws, or send us the parameters so that our CNC department can carry out the finished modifications.

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.

What should I do if I need a non-standard module that is not currently in the standard range?

If time is short and you need a specific size, we offer professional 3D printing from modern glass-fibre-reinforced materials. It is an outstanding, durable solution for an urgently needed spare part, for prototyping or for gears with lower loads, allowing you to restore continuity of operation very quickly.

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.

Where is this product used?

Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.

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.
