The Ultimate Space-Saver! 【Matex Planetary Gear Module】 Wide Range of Specifications!

The Ultimate Space-Saver! 【Matex Planetary Gear Module】 Wide Range of Specifications!

Our Planetary Gear Modules are the result of cutting-edge materials technology and processing technology! We have extensive experience from design and development to mass production!

The Matex Planetary Gear Module (or increaser) is a type of reducer (or increaser) using a planetary gear mechanism. It consists of a sun gear, planetary gears, an internal gear, and a planetary carrier. 【Features】 - Coaxial reduction of motor input. - By stacking several units in a multi-stage configuration, the speed ratio can be multiplied. For example, with a first-stage speed ratio of 5:1 and a second-stage ratio of 3:1, the total speed reduction of a 2-stage unit becomes 15:1. - By reversing the input and output, this product can be used as a speed increaser. - Since this is a unique product that only consists of the planetary gear mechanism, our customers have the freedom to design the optimal casing. *For installation and casing details, please download the ''Design Guide'' below.

Matex Provided Reducers to Multiple Teams at the 20th Student Formula Competition!

Matex Provided Reducers to Multiple Teams at the 20th Student Formula Competition!

Thanks to its high degree of design freedom and cost performance, Matex reducers were crucial to enhancing the torque of the EV cars participating in the Student Formula competition.

The Student Formula Competition, modeled after the American "Formula SAE," allows students to form teams and develop and manufacture compact formula-style racing cars over the course of about a year. This competition enables students to learn the essence of manufacturing and its processes, while experiencing the challenges, excitement, and joy of creating. This mission is very much aligned with ours, which is why Matex has become a sponsor of the competition starting this year. We are also sponsoring teams participating in the EV category, such as the University of Tokyo, Aichi Institute of Technology, and Kanagawa Institute of Technology, by providing planetary gear reducers. The competition was held for the first time in three years at Ecopa (Ogasa Mountain Comprehensive Sports Park) in Shizuoka Prefecture from September 6th (Tuesday) to September 10th (Saturday), 2022. https://www.jsae.or.jp/formula/jp/ For those: ■ Considering the use of planetary gear reducers ■ Limited design space for the drive unit ■ Want to reduce speed with input and output on the same axis ■ Looking for a manufacturer that can prototype fully customized reducers, etc. Matex has the solution!

We offer a "Planetary Gear Reducer" that resolves the issues of planetary gears through a load distribution mechanism. Our unit, which pursues a planetary load distribution holding mechanism, achieves a compact design with high torque. The special structure that holds the planetary load eliminates gear noise, and there is no change in noise due to load fluctuations. Additionally, there is no acceptance inspection for gear specifications, and since the installation is on a co-axial shaft, it is suitable for product design. 【Features】 ■ Efficiency ■ Load distribution mechanism ■ High torque ■ Gear unitization ■ Wide variety of models and reduction ratios, etc. *For more details, please download the PDF or feel free to contact us.
