3D Scanning Boosts Reduction Gearbox Housing Inspection Efficiency by 30-Fold

June 3, 2024

Using the FreeScan UE 3D scanner has significantly increased the efficiency of large reduction gearbox housing inspections, achieving a 30-fold improvement. This case study explores the challenges of traditional inspection methods and how SHINING 3D’s advanced scanning solution addresses these issues, providing faster, more accurate results.

Reduction Gearbox Housing Inspection

Various industries commonly use reduction gearboxes in applications like conveyors, cranes, and automotive systems. The reduction gearbox housing is the outer shell that encases the gears and other internal components of the gearbox. It serves multiple functions:

-Protecting the internal parts from external contaminants, such as dust and moisture.

-Providing structural support to maintain the alignment and position of the gears.

-Reducing friction and wear on the moving parts with lubricants.

Regular inspection of the reduction gearbox housing is crucial for several reasons:

Firstly, ensuring the housing is intact and sealed properly prevents contaminants from entering the gearbox and lubricant from leaking. This can prevent premature wear and damage to the gears. Secondly, identifying cracks and deformations that could compromise gearbox integrity and cause catastrophic failures. Thirdly, an undamaged housing ensures correct gear alignment, which is vital for efficient and smooth gearbox operation.

Challenges of Traditional Inspection Methods

Inspecting reduction gearbox housings is fraught with difficulties due to their irregular surfaces. Manual measurement methods often result in large errors and low efficiency, requiring considerable time and effort to achieve even moderately accurate results. Moreover, this inaccuracy and inefficiency can lead to higher costs and increased downtime in industrial operations. For example, inspecting a 2.4-meter, 2-ton housing traditionally takes up to 2 days.

FreeScan UE, in conjunction with the inspection software, allowed the same housing (2.4 meters long, weighs more than 2 tons) inspection to be completed in less than half an hour. 

The FreeScan UE has accuracy of up to 0.02mm and, in conjunction with photogrammetry, volumetric accuracy of up to 0.02mm + 0.025mm/m, resulting in accurate scanning results without rework.

By importing the 3D data of a complete housing into the inspection software, you can quickly inspect the entire component for deformation and measure important dimensions at some assembly points.
