Custom Gears for the Automotive Industry

We manufacture custom gears and precision gearing components for the automotive industry. Our production capabilities allow us to supply gears for gearboxes, drive systems, testing equipment, production machinery, special-purpose vehicles, and other automotive applications where accurate and reliable torque transmission is essential.

Automotive gears must meet demanding requirements for dimensional accuracy, load capacity, durability, smooth operation, and resistance to repeated stress. Using advanced manufacturing technologies and many years of experience in gear production, we deliver components designed for reliable operation throughout their required service life.

Precision Gears for Automotive Applications

Gear mechanisms are used to transfer rotational motion and torque between shafts while maintaining a precisely defined transmission ratio. In automotive systems, they must operate reliably under changing speeds, repeated acceleration, vibration, elevated temperatures, and varying loads.

The required gear design depends on the application, shaft arrangement, transmitted torque, operating speed, available installation space, and required noise level. We manufacture each component according to the customer's technical drawings, specifications, or an agreed production design.

Where Automotive Gears Are Used

Our gears and gearing components can be used in a wide range of automotive and transport-related applications, including:

• Manual and special-purpose gearboxes
• Industrial transmissions used in automotive production
• Differential and axle mechanisms
• Auxiliary drive systems
• Steering and positioning mechanisms
• Testing and development equipment
• Assembly lines and automotive production machinery
• Special-purpose, utility, and off-road vehicles
• Replacement parts for older or discontinued machinery

We can manufacture both individual replacement gears and components intended for newly developed mechanisms. Our flexible production enables us to support repairs, modernization projects, prototype development, and repeat deliveries.

Types of Gears for the Automotive Industry

Depending on the required operating characteristics and shaft configuration, we manufacture various types of automotive gears:

• Spur gears – a reliable and efficient solution for transmitting torque between parallel shafts.
• Helical gears – suitable for applications requiring smoother engagement, quieter operation, and higher load capacity.
• Bevel gears – used to transmit torque between intersecting shafts, most commonly arranged at a 90° angle.
• Cyclo-Palloid bevel gears – designed for smooth and reliable angular power transmission in demanding mechanisms.
• Worm gears – suitable for compact drives requiring high transmission ratios and smooth operation.
• Internal and external gears – used in planetary gear systems, transmission mechanisms, and specialized assemblies.
• Involute splines – used for precise torque transmission between shafts, hubs, and other rotating components.

Custom Manufacturing Based on Technical Documentation

We manufacture automotive gears according to supplied technical drawings, 3D models, dimensional specifications, or existing samples. Every project is evaluated individually, taking into account the required:

• Gear type and tooth geometry
• Module and number of teeth
• Gear diameter and face width
• Pressure angle and helix angle
• Material and heat treatment
• Dimensional tolerances and accuracy class
• Surface finish
• Operating speed and transmitted torque
• Expected service life and operating conditions

If the original technical documentation is unavailable, production may also be assessed on the basis of an existing gear or component. This is particularly useful when replacing worn or damaged parts for older gearboxes, production machinery, or specialized vehicles.

Gear Manufacturing Technologies

We select the manufacturing process according to the component dimensions, gear geometry, required accuracy, material, and production volume. Our gear manufacturing capabilities include:

• Gear hobbing
• Gear shaping using Fellow and MAAG systems
• Gear milling
• Internal and external gear machining
• Involute spline machining
• Gear grinding
• Precision CNC machining
• Heat treatment according to customer requirements

The combination of different manufacturing technologies allows us to produce gears in a wide range of dimensions and configurations. We can select the appropriate process for prototypes, individual replacement parts, small production batches, and repeat series.

Gear Grinding for Increased Precision

For applications with particularly demanding requirements, we also offer gear grinding. This finishing process improves tooth geometry, dimensional accuracy, surface quality, and contact conditions between mating gears.

Precisely ground gearing contributes to smoother engagement, reduced vibration, more uniform load distribution, lower operating noise, and longer service life. It is therefore especially suitable for gears operating at higher speeds or under repeated and variable loads.

Materials and Heat Treatment

The material used for an automotive gear must correspond to its expected load, dimensions, operating conditions, and required service life. Depending on the customer's specification, we manufacture gears from standard and special steels suitable for machining and subsequent heat treatment.

Heat treatment can increase tooth surface hardness, wear resistance, fatigue strength, and overall component durability. According to the technical requirements, the manufacturing process may include appropriate hardening or other heat-treatment operations.

The specific material and heat-treatment method are always selected according to the required mechanical properties and the conditions in which the finished gear will operate.

Quality Control Throughout the Manufacturing Process

Reliable automotive gearing requires consistent quality at every stage of production. We therefore inspect the relevant dimensions and manufacturing parameters throughout the process, from the initial machining operations to the final inspection of the finished component.

Depending on the project requirements, quality control may include:

• Inspection of basic component dimensions
• Verification of tooth geometry
• Inspection of the module, tooth profile, and pitch
• Runout and concentricity measurement
• Surface and visual inspection
• Verification of compliance with technical documentation

Careful manufacturing control helps ensure that the gears fit correctly into the final assembly and provide reliable power transmission under the specified operating conditions.

Prototype, Individual, and Series Production

We provide flexible production tailored to the scope of each project. We can manufacture:

• Individual replacement gears
• Prototype components for development and testing
• Small production batches
• Repeat series according to agreed specifications

This flexibility allows us to work with gearbox manufacturers, automotive suppliers, engineering companies, repair specialists, development departments, and operators of specialized vehicle fleets.

Replacement Gears for Repairs and Modernization

In addition to components for newly manufactured equipment, we also produce replacement gears for the repair and modernization of existing machinery. Custom manufacturing is an effective solution when the original part is no longer available, has an unusually long delivery time, or needs to be modified for new operating requirements.

Production can be based on the original technical documentation or, subject to technical assessment, on a supplied sample. This makes it possible to restore the operation of gearboxes, automotive production equipment, special-purpose vehicles, and older mechanical systems.
