Spur gear module 2.5 z=48 with hub

Product Description

Spur gear module 2.5, z=48, with hub

This module 2.5 spur gear (48 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. 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

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.

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).

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.

In which applications do helical module gears perform well?

Helical teeth ensure smoother engagement, which drastically reduces noise and vibration at high rotational speeds. They are used in precision speed reducers and machine tools, bearing in mind, however, the need to use thrust bearings (absorbing axial forces).

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.
