What we do

GearLab is independent of software resellers, so every recommendation follows the engineering problem, not a licence.

  • Design and calculation

    Design, calculation and verification of power transmissions to ISO, DIN and AGMA, optimised for size, weight, efficiency and cost.

  • NVH and multibody simulation

    Transmission error, microgeometry and flexible multibody models of e-drives and gearboxes, from structure-borne to air-borne noise, in KISSsoft and RecurDyn.

  • Gearbox design

    Gearboxes for stationary and mobile applications, starting from a specification we write with you or for you.

  • Failure analysis

    Root-cause analysis of gearbox failures: site visits, systematic examination of components and lubricants, and clear recommendations to prevent a repeat.

  • Vibration testing

    With testing partners: powertrain and vehicle NVH, experimental modal analysis, shaker tests and troubleshooting.

  • Prototyping

    Prototypes that represent the final product, so concepts and performance can be validated before series production.

Cover of the book Cylindrical Gear Design by Davide Marano
Cylindrical Gear Design, with examples in KISSsoft

An engineering practice built on research.

GearLab was founded in 2018 by Dr. Davide Marano. He combines gear design, NVH and computational modelling with the verification and validation methods that make simulation results trustworthy.

GearLab contributes to international technical work with ISO, AGMA, VDI and UNI, and presents its research at the AGMA Fall Technical Meeting and the VDI International Conference on Gears.
