Spur gear module 2 z=28 with hub

Product Description

Spur gear module 2, z=28, with hub

The module 2 spur gear z=28 with hub is a precision gear transmission component designed to transmit high torques at a constant ratio. 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

How can wear of the gears in a module gearbox be diagnosed?

Wear is easiest to spot from a change in the tooth profile - it becomes sharp at the tip, and the backlash increases dramatically, which shows up as loud knocking when the machine changes its direction of rotation.

How can you recognise a manufacturing defect in a gear when receiving the goods?

It is worth checking the radial runout (the gear should not "wobble" on the shaft), the uniformity of the pitch between teeth and the smoothness of the tooth surface - visible burrs, dents or uneven pitch are a signal to file a complaint.

Does a module gear require constant lubrication?

Enclosed gears (in speed reducers) run in oil or grease, while open systems (gear + rack) require periodic manual lubrication - without it, friction and tooth wear increase many times faster.

How do you measure a worn tooth to choose the right replacement?

It is best to measure the outside diameter (Dz) and count the teeth (Z), and calculate the module from the formula m = Dz / (Z+2); it is also worth measuring the bore diameter so that the replacement fits the same shaft without additional machining.

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.
