The traditional method of manufacturing wheels by gear milling is laborious, accompanied by a significant waste of material into chips.

A cartoon explaining the disadvantages of the traditional method of manufacturing gears.

Technological equipment for rolling toothed profiles.

The rolls, pressing out the heated workpiece, are embedded in its surface.

The metal moved by the rolls comes out and forms teeth.

A cartoon that clearly explains the process.

The durability of rolled wheels is 20-40% more than those made by the traditional method.

A rolling mill on which wheels with a diameter from 400 to 1000 mm can be rolled.

The production time of the wheel on the rolling mill is 3 min.

One operator maintains several rolling mills.

A mill on which it is possible to roll wheels from stamped unprocessed blanks.

Stamping, heated by high-frequency currents, is fed to the pre-rolling by smooth rolls, where it acquires the necessary shape and dimensions and, only after that, enters the gear rolling position.

Asterisks are used to transform mechanical energy

chain gears.

Mill for rolling single and double row stars.

The process of their production is similar to rolling gears.

In 20 seconds, the asterisk is ready.

During the rolling process, the surface of the toothed crown expands by up to 40%, which allows the use of a thinner initial workpiece.

A modification of the mill is presented, on which the heat treatment of the asterisk is provided.

After forming the asterisk, using the heat of the initial heating, its toothed crown is quenched.

Checking the teeth for hardness.

The design feature of double-row sprockets is that the processing takes place in two stages.

First, two crowns are formed on the workpiece.

Then, after intermediate heating, it is fed for rolling the teeth.
