Gear polishing: for optimizing transmission performance

febbraio 06, 2024
In mechanical engineering, gear polishing represents the pinnacle of precision for perfecting transmissions. This article delves into the delicate polishing process, revealing how to optimize toothed surfaces to reduce friction, increase efficiency and ensure optimal performance, with a particular focus on advanced applications such as electric vehicle transmissions.

What is gear polishing?

Gear polishing is a crucial phase in the production of gears and is aimed at improving the quality of their toothed surfaces. Through controlled material removal, this process ensures tighter tolerances and a flawless surface finish.

Gear polishing aims to refine toothed surfaces, significantly contributing to the performance of transmissions. With key objectives such as reducing friction, increasing operating life and improving efficiency, this process proves indispensable in applications requiring precision and silence.

Applying gear polishing

Gear polishing is a crucial step after the grinding phase. During this operation, the gears undergo a smooth transition from grinding to polishing, using finer abrasive grits to achieve a smooth, flawless surface finish.

Gear polishing goes beyond the aesthetic perfection of surfaces, focusing on critical parameters such as average roughness and groove depth. These details influence not only the visual appearance but also the operational performance, optimizing oil adhesion and improving heat dissipation. However, this technique also has several limitations, including geometric complexity and manufacturing costs.

In conclusion, gear polishing emerges as a fundamental practice for improving transmissions. While it presents challenges, its targeted adoption can lead to superior performance, extended operational life and optimized operation.
