Gear Segment for Bucket wheel excavator

Fabrication of an gear-segment for Bucket wheel excavator

Gear Segment
Bucket wheel excavator
Input=___ rpm / ____ KW

Scope of work:

We performed an inspection and revision on Gear Segment of Bucket wheel excavator.

One of our customers had damage to a ring gear of a swing of a Bucket-wheel excavator.
Only one tooth was badly damaged. It's our mission to quickly generate a solution.
Given the lead times of material for an entire quarter circle, we have chosen this quarter again be divided into 3 sections.
As a result, we were able in a very short time to generate a solution. The three tooth segments were made of materials 42CrMo4V + QT with certification to EN 10204 - 3.1, n = 24, Z = 13, pressure angle = 20 degrees, intermediate annealing and stress-relieved.

Due to the privacy of our customer, we show left an equivalent system.

The ring gear was heavily damaged and even had a broken tooth. Because of long delivery times of material, we decided to change the design. Strength calculations showed equivalent strength. Hereafter we generated 3D solids.

One block of material, One program, Start!

On our 5-axis milling machine, we first pre-machined the 3 blocks. After the machining the blocks were annealed and stress-relieved. After that the final machining could start.
