High-Speed & High-Torque Gearboxes

Tandler develops specialist gearbox solutions for demanding applications where standard catalogue products are not sufficient. From very high-speed test systems to extreme torque requirements in heavy-duty drive applications, our gearboxes are engineered around the exact needs of the system to deliver precision, durability and reliable long-term performance.

By building on proven design principles and established gearbox platforms, we can often provide a practical and efficient route to a specialist solution. Depending on the application, this may involve adapting an existing design or developing a more extensively engineered gearbox to suit specific operating, installation and environmental requirements.

Whether the priority is very high rotational speed, exceptional torque capacity, compact installation or integration into an existing machine or test rig, our focus is always on delivering a gearbox solution that is technically robust, practical to integrate and built for dependable service.

High-Speed Gearboxes

As electric motors, drive systems and test equipment continue to develop, the demand for gearboxes capable of operating at increasingly high rotational speeds continues to grow. This is particularly evident in the testing and development of electric vehicle motors and transmissions, where modern test rigs must operate safely, reliably and consistently under extreme speed conditions.

Application requirements of up to 30,000 r/min are now becoming increasingly common. Speeds that were once considered impractical are now a routine part of advanced testing and development programmes. Through ongoing advances in gear design, bearing technology and lubrication systems, Tandler has developed the expertise and manufacturing capability to engineer gearboxes that deliver the stability, precision and durability required in these demanding environments.

Every high-speed gearbox we supply is designed specifically for the application. By working closely with our customers, we ensure that each unit is engineered to suit the exact speed, torque, load case and operating conditions of the system in which it will run. This collaborative approach allows us to deliver gearbox solutions that not only meet performance targets, but also provide long-term reliability and safe operation.

A high-speed gearbox, whether used as a speed-increasing or speed-reducing unit, can significantly extend the capability of an existing test rig. Dynamometers, motors and associated systems originally intended for lower operating speeds can often be adapted to achieve much higher performance levels, reducing the need for complete system replacement.

This can provide a number of practical benefits, including:

• greater flexibility within a single test setup

• extended use of existing equipment

• reduced cost and shorter lead times

• faster development and testing cycles

Features & Benefits

• fully customised gearbox designs tailored to each application

• bearing arrangements and lubrication systems engineered for very high rotational speeds

• custom housings and mounting interfaces for straightforward integration

• suitable for speed-increasing or speed-reducing duties

• shorter lead times compared with fully bespoke system redesigns

• reduced overall investment by allowing existing test equipment to be retained

High-Torque Gearboxes

Tandler’s standard spiral bevel gearboxes offer rated torques of up to 10,000 Nm, covering the majority of industrial and testing applications. However, some operating environments demand substantially higher torque capacity, beyond the limits of a standard catalogue solution.

To meet these more demanding requirements, we offer high-torque gearbox solutions based on our proven design principles. Depending on the application, this may involve modified gearing, upgraded bearing arrangements, reinforced shafts, or the development of a fully bespoke gearbox engineered to suit the specific duty.

High-torque gearboxes are most commonly required in lower-speed applications, although this is not always the case. Whatever the operating conditions, Tandler has the capability to design and manufacture both right-angle and helical (parallel shaft) gearbox solutions that combine high strength with the precision, durability and reliability expected in demanding service.

Where possible, we build on existing catalogue platforms rather than developing an entirely new system from the outset. This approach can provide a more efficient route to a high-torque solution while retaining the benefits of a proven gearbox design.

Typical advantages include:

• faster delivery times

• reduced development costs

• dependable performance based on established designs

Features & Benefits

• fully customised gearbox designs for extreme torque applications

• high-torque solutions available in right-angle and helical configurations

• modified gears, reinforced shafts and upgraded bearing arrangements available

• custom housings and mounting arrangements for easier system integration

• shorter lead times through adaptation of our standard gearbox range

• proven design basis for reliable long-term performance

Built Around Your Application

Every specialist gearbox project begins with a clear understanding of the application. Our team works with customers to assess the required performance, installation envelope, operating environment and interface requirements before recommending the most suitable solution.

In some cases, a modified version of an existing Tandler gearbox may provide the best route forward. In others, a more extensively engineered solution may be required. In either case, the objective remains the same: to deliver a gearbox that is technically robust, practical to integrate and designed for reliable operation in demanding conditions.
