Special Gearboxes
drive technology Harnisch develops custom gearboxes for demanding applications in mechanical and plant engineering. Each solution is tailored to the specific requirements regarding torque, speed, gear ratio, installation space, and operating conditions.
From concept development through design to production-ready engineering, our focus is on technical functionality, reliability, and cost-effectiveness. We combine in-depth expertise in drive technology with many years of experience in the design and manufacture of complex gear solutions. Even when faced with unusual requirements and challenging technical constraints, we develop well-thought-out and practical solutions. You can find an overview of the variety of gearboxes we have developed to date and the breadth of our experience in the section „Projects“,
Damage Analysis
drive technology Harnisch investigates and evaluates damage to industrial gearboxes and drive systems with the goal of systematically determining its causes.
The focus is particularly on gear damage, bearing damage, and shaft fractures, as well as their possible causes and effects on plant operations. In addition to examining the damage patterns, the design, load conditions, and operating conditions of the gearbox are taken into account. Operating and process data—such as iba data—form an important basis for analyzing torques, rotational speeds, load cycles, and dynamic load peaks. By linking this data to the identified damage characteristics, the causes of damage can be evaluated more thoroughly, and targeted measures for remediation and prevention can be derived. The goal is to prevent recurring gearbox damage, increase operational reliability, and sustainably reduce unplanned plant downtime.
Design Review
drive technology Harnisch assists companies in the systematic review and evaluation of gear designs and industrial drive systems.
The goal is to identify design weaknesses at an early stage, assess technical risks, and improve the reliability of the design. In this process, key components such as gearings, shafts, bearings, and housings are examined with regard to their design, load-bearing capacity, and functionality. In addition to computational verifications, the assessment also takes into account manufacturability, ease of assembly, maintenance requirements, and actual operating conditions. Drawing on many years of experience in the design of custom gearboxes, 
develops practical improvement proposals that combine technical certainty and cost-effectiveness. The result is an independent, well-founded assessment with concrete recommendations for optimizing the design and reducing technical risks.
Retrofit
drive technology Harnisch helps companies modernize and technically upgrade existing gearboxes and industrial drive systems.
The goal is to maintain or improve the operational safety and performance of existing systems while extending their economic service life. To this end, the condition of existing components, current operating conditions, and future requirements are systematically analyzed. Based on this analysis, appropriate measures are developed—such as redesigning individual parts, replacing critical components, or adapting the system to changed performance requirements. The focus is on technically sound solutions that make the most effective use of existing plant structures and avoid costly new purchases. With many years of experience in the manufacture of special gearboxes, supports the technical evaluation and development of suitable retrofit solutions—practical, cost-effective, and designed for long-term reliability.
Project Support
drive technology Harnisch supports machinery and plant manufacturers in the technical planning and implementation of challenging projects in the field of industrial drive systems.
We support projects from the concept phase through design and engineering to manufacturing, installation, and commissioning. We place particular emphasis on aligning technical requirements, evaluating interfaces, and identifying potential risks at an early stage. Drawing on our in-depth expertise and many years of practical experience, we assist project teams in making technical decisions and solving complex design challenges. When necessary, we take on the technical coordination between design, manufacturing, suppliers, and plant operators to ensure the project runs smoothly. Our goal is to improve technical quality, ensure on-time delivery, and maximize cost-effectiveness, reliably guiding projects to success.
Commissioning
drive technology Harnisch provides technical support to companies during the commissioning of gearboxes and industrial drive systems.
The goal is to ensure the proper functioning of the drive components and to enable reliable plant operation from the very beginning. To this end, operating parameters, running characteristics, lubrication, and temperature and vibration trends are specifically checked and evaluated. This allows anomalies and potential technical issues to be identified early on, enabling appropriate corrective measures to be taken. Through close collaboration with the relevant departments and commissioning personnel, supports systematic fault analysis and the optimization of operating settings. In this way, helps reduce startup problems, prevent unplanned downtime, and achieve safe, stable, and efficient plant operation.
