About the Event

The Brazilian Gear Conference ITA-WZL appears as a response to the potential demands for technological solutions and innovation research for gears, as one of the initiatives of the partnership between CCM-ITA (Brazil) and WZL-RWTH Aachen (Germany).

The event approaches the topics of manufacturing technologies, product development and testing of gears, distributed in blocks considering the knowledge areas of: Surface integrity, Design for Manufacturing, Additive Manufacturing, and Power Density.

The technical seminars approach the global state-of-the-art and success cases of Academic-Industry partnerships in gears and power transmission systems. Internationally renowned special guests from the industrial sector will participate in the event´s discussion panels. At the end of the first day, an immersive Product Development Journey at CCM-ITA facilities with limited number of participants will be conducted, followed by a cocktail. The second day will be closed with the CCM-ITA Open Doors.

The Brazilian Gear Conference ITA-WZL 2025 (BGC 25) will take place on August 13th. and 14th, 2025 at Parque Tecnológico São José dos Campos, in the city of São José dos Campos, São Paulo, Brazil. The event’s structure enables the participant to attend on either one or two days of the event.

M.Sc. Gilberto Martins

This presentation will contextualize the challenges of gear design for the agricultural market and explore potential optimization strategies to increase torque density. It will also present results on surface integrity and fatigue life enhancement using the Shot Peening and Superfinishing processes. Finally, it will discuss the gear manufacturing chain incorporating the superfinishing process, which may extend to the rolling contact fatigue on gears.

Mr. Gerrit Hellenbrand M.Sc

At the WZL, a lifetime prediction model for the tooth root was developed considers crack growth rate with the Nasgro equation. The model uses local material properties such as hardness, residual stresses, fracture toughness and the stress intensity threshold to calculate fatigue life from crack initiation to fracture. The first validations of the model were carried out with pulsator tests, further investigations are being carried out on the WZL high-performance back-to-back test rig.

M.Sc. Izabel Criscuolo

The presentation will focus on investigating the influence of both substrate residual stress state and topography on Nb and Ti doped MoS2 coatings for low-friction gear durability

15:10 - 15:40 Coffee Break

M.Sc. Caio Gomes

As gear standards underestimate the residual stress effects in the fatigue lifetime, a strategy was developed to employ this knowledge in the design phase. A case study is presented, where the joint effect of residual and actuating stresses were considered to downsize a gear while keeping its tooth bending fatigue lifetime. Indirect economical benefits regarding manufacturing time and energy consumption, besides mass/volume reduction, are highlighted.

Mr. Christian Westphal M.Sc.

The aim of the report is to investigate the effects of waviness on the acoustics behaviour of gear pairs. In this paper, an anlytical model is used to explain the effects in theory. Afterwards the FE-based tooth contact analysis software ZaKo3D is used to calculate the behaviour in detail. Key takeaways are, that a difference between βᴮ and βᵂ does not immediately lead to a reduction of the amplitude of the waviness order. The effect depends on the wavelength and the tooth width. Also, it is shown, that there are cross influences between width crowning and waviness.

16:40 - 17:30 Experts Panel Discussion

After a full day of technical discussions, a special evening is offered to BGC23 participants at a cocktail party. Soon, more information

Esta apresentação contextualizará os desafios do projeto de engrenagens para o mercado agrícola e explorará estratégias de otimização superficial para aumentar a densidade de torque. Também apresentará resultados sobre a integridade de superficie e a melhoria da vida em fadiga utilizando os processos de Shot Peening e Superacabamento. Por fim, discutirá a cadeia de fabricação de engrenagens incorporando o processo de superacabamento, que pode se estender até a bancada de testes de fadiga de contato de rolamento em engrenagens.

M.Sc. Izabel Criscuolo

A apresentação abordará a investigação da influência do estado de tensão residual do substrato e da topografia nos revestimentos de MoS2 dopados com Nb para a durabilidade de engrenagens de baixo atrito.

M.Sc. Guilherme Guimarães

The performance of Binder Jetting and Laser Powder Bed Fusion Gears were compared to conventionally manufactured gears. The performance evaluation was carried out through Bending Fatigue, Contact Fatigue and NVH assesment

Eng. Matheus Rubik

Additive manufacturing processes such as Binder Jetting introduce porosity and surface integrity concerns in gears. This presentation examines how a dual approach to shot peening, combining densification and the induction of compressive residual stresses, can mitigate these issues and enhance fatigue performance.

09:50 - 10:40 Coffee Break

Eng. Matheus Fernandes

Improved NVH performance and lightweight designs are increasingly demands for electrified gearboxes. This study explores the design freedom of Powder Metallurgy to develop an optimized gear body and increase the structural damping for improved vibration absorption through polymer infiltration.

M.Sc. Felipe de Sá

Powder metallurgy poses particular challenges for the surface integrity of gears. This presentation explores how experimental and simulation tools can optimize the decision for the finishing manufacturing chain to enable high performance applications.

11:40 - 12:25 Technological Demonstration

12:25 - 13:40 Lunch

Mr. Emil-Elias Breuer M.Eng.

The aim of productive manufacturing is to ensure workpiece quality while minimizing manufacturing costs, whereby tool wear influences both workpiece quality and manufacturing costs. In this paper, an algorithm for detecting and quantifying tool wear on gear cutting tools using computer vision methods is presented. For this, the suitability of traditional and deep learning-based computer vision methods for tool wear detection is compared. Overall, good agreement is achieved between the algorithm-generated and manually measured wear curves with an average absolute difference of ΔVBmax = 7.99 µm for bevel cutting and ΔVBmax = 19.95 µm for gear hobbing.

M.Sc. Bruno Cardozo

As gearboxes are downsized, thermal dissipation becomes a challenge. This presentation explores a method to evaluate heat distribution and quantify oil churning through Computer Vision techniques.

14:40 - 15:30 Experts Panel Discussion
