SPACECADAPTCOAT® for greatly improved gear backlash

SPACEADAPTOCOAT^® is an innovative polymer coating to improve gear backlash in toothed gear systems. The coating effectively reduces noise emissions, improves running smoothness, simplifies assembly, and optimizes NVH behavior.

Thanks to precisely optimized tooth flanks, the coating ensures quieter, more durable and, thanks to simplified assembly, more cost-effective drive systems.

Coatings in gear trains

Gear backlash in modern drive systems

Gears are often a major source of noise emissions. Particularly critical challenges in modern drive systems include:

Disturbing gear noises such as howling or rattling due to imprecise gear backlash
Difficult assembly due to complex manual adjustment of the gears
Higher energy consumption due to unnecessary friction in gears that are not optimally aligned
Restricted space for installation, which makes complex split gear solutions impractical

These problems can be solved efficiently using SPACEADAPTOCOAT^®. The polymer and/or metal coating acts as a precision optimization coating for gears. The coating is applied directly to the component and enables precision optimization of the gear backlash.

The thickness of the coating varies between 10 and 70 µm and is adapted to the application requirements. During final assembly, the gears are precisely optimized without backlash. During the first cold run with the motor, the coating dissolves into fine particles, which optimizes the intermeshing of the gears.

Maximum efficiency thanks to reduced gear backlash

Optimization of gear backlash: SPACEADAPTOCOAT^® reduces tolerance stack up and optimizes gear backlash, reducing motor noise by up to 10 dB.

Cost-effectiveness: The precision coating significantly reduces assembly times, which lowers production costs and means that manual adjustments are no longer necessary.

Performance: SPACEADAPTOCOAT^® achieves specific NVH optimization of gear-driven systems.

Lightweight construction: SPACEADAPTOCOAT^® eliminates the need for complex split-gear systems, making gears more compact while reducing weight and carbon emissions.

Frequently asked questions on our coatings

How does SPACEADAPTOCOAT® reduce noise?

Thanks to the precision optimization of gear backlash, SPACEADAPTOCOAT^® prevents disturbing noises such as howling and rattling. Comparative tests show that this technology can reduce gear noise by up to 5 dB.

How does the coating work during the assembly process?

During final assembly, the gear backlash is precision optimized by the SPACEADAPTOCOAT^® coating. During the first cold run with the motor, the coating dissolves into fine particles (SPACECOAT^®) and adapts to its counterpart gear (SPACEADAPTOCOAT^®), resulting in optimized backlash.

For which applications is SPACEADAPTOCOAT® suitable?

SPACEADAPTOCOAT^®is used in various drive and gear systems, including:
