From the Initial Problem Statement to the Finished Gearbox –
Design that makes all the difference.

A good gearbox isn’t built on the assembly line. It’s built on a thorough understanding of the problem.

CHEMNITZER ZAHNRADFABRIK supports your drive projects from the very beginning: from the technical analysis of your requirements through concept development and design to engineering, manufacturing, assembly, and commissioning. Our team of experienced design engineers and engineers combines decades of expertise with modern calculation and CAD tools.

What sets us apart: We think in terms of solutions, not standard processes. For us, every project is a unique engineering challenge that deserves a well-thought-out answer—not a one-size-fits-all solution.

The result is a gearbox that not only works but does exactly what you need—reliably, durably, and cost-effectively.

Our Development Process – Step by Step

The path from the initial consultation to the installed gearbox is structured — but never rigid. We tailor our process to the complexity and requirements of your project.

Idea & Problem Definition

It all begins with an open-ended question: What should the gearbox be capable of, and under what conditions? Together with you, we define the technical constraints—torque, speed, installation space, environment, service life, and safety requirements.

Concept Development

Based on your requirements, our design engineers develop several potential solutions. We evaluate them together with you—both technically and economically—and select the concept that best fits your needs.

Design & Calculation

The design of gear teeth, shafts, and bearings is carried out using modern calculation methods. In doing so, we take into account load-dependent factors, efficiency, vibration behavior, and strength—with the goal of creating a gearbox that is not only strong enough but also runs efficiently and quietly.

Design & CAD

Our design engineers create complete 3D models and manufacturing documentation. Exchanging CAD data with your team is a given—we work with standard formats and adapt to your system environment.

Manufacturing in Chemnitz

All key manufacturing steps take place at our plant in Chemnitz. This high level of vertical integration ensures quality, on-time delivery, and short lines of communication—without relying on external suppliers.

Prototype Testing & Optimization

Where appropriate, we rely on prototype testing to validate the gearbox under real-world conditions. Findings from these tests are directly incorporated into the optimization process—before series production begins.

Assembly & Commissioning

The finished gearbox is assembled, tested, and prepared for use at our facility. Upon request, we also provide on-site support for commissioning.

An Overview of Our Design Expertise

The work of our design department goes far beyond simply drawing components:

  • Drive Concept Selection
    Which gear unit type, drive type, and gear ratio strategy is optimal for your application?

  • Gear Tooth Optimization
    Load-dependent calculation and optimization for maximum efficiency and service life

  • Bearing and Shaft Design
    Sizing based on load, operating time, and environmental conditions

  • Efficiency analysis
    Measurement and optimization of gearbox efficiency for energy-efficient drives

  • Vibration and noise analysis
    Identification and reduction of noise and vibration sources

  • Strength and weight optimization
    Lightweight design concepts for weight-critical applications

  • Integration of Sensors and Electronics
    Sensors, temperature sensors, speed transducers, and other components integrated upon request
