Special gears are special tooth profiles that go beyond the standard tooth geometries and are developed for individual applications. These gears are often used in situations where special requirements are placed on power transmission, precision or load capacity. The production of special gears requires advanced manufacturing technologies and precision tools. State-of-the-art CNC machines are used to realize the exact geometry of the gears and to ensure a high surface quality. An important aspect of special gearing is the consideration of individual customer requirements. The design is carried out in close cooperation with the customer to ensure an optimum solution for their specific application. Ongoing research and development in the field of special gears aims to integrate innovative technologies and materials in order to further improve the performance and reliability of special tooth profiles.

In the technical world, complementary interlocking refers to the optimal coordination and cooperation of different technical elements in order to create an efficient overall system.

Complementary gearing occurs when different components of a system are designed in such a way that they support and improve each other in order to achieve higher performance. This can be achieved, for example, through different tooth thicknesses or minimally different helix angles of the tooth flanks, different pressure angles of the tooth flanks or similar of individual gears. This ensures that tooth profiles and geometries are optimally matched to each other in gearboxes.

Complementary gearing is a precisely designed gear connection whose performance is ensured by carefully coordinating various parameters. Adjustable influencing variables such as the number of teeth, module and tooth profile enable individual adaptation to specific application requirements.

Profile modifications can be used to reduce noise and vibration, resulting in quiet and vibration-free performance. The tooth geometry is designed to enable low-friction engagement and even load distribution between the teeth. State-of-the-art manufacturing technologies such as CNC milling or grinding ensure tight tolerances and a precise fit of the teeth.

Continuous quality controls throughout the entire manufacturing process ensure compliance with the highest standards. Precise heat treatment methods optimize the hardness of the teeth and increase their wear resistance.

In addition, elasticity behavior and temperature resistance are taken into account to ensure stable performance under different operating conditions.

Low-Loss gearing

[Translate to EN:] Sonderverzahnung Low Loss

The low-loss gearing is characterized by a special tooth geometry that ensures low-friction engagement and even load distribution.

High-quality materials such as alloy steel are used to minimize wear and maximize service life.

Surface coatings such as nitriding reduce friction and wear on the tooth flanks.

The dimensions of the teeth are carefully calculated to ensure stable toothing and to carry the loads evenly.

In addition, high-precision manufacturing processes such as grinding, planing or hobbing are used to ensure tight tolerances and an exact fit of the teeth.

The gearing can also have special profile modifications to minimize noise and vibrations during operation.

The number of teeth and the module are adjusted according to the requirements of the application to ensure optimum power transmission and load capacity. The elastic properties of the material are taken into account to allow a certain flexibility and to absorb shock loads.

SPN can pass on its experience in low-loss gearing for both steel-steel gear pairings and plastic-steel pairings.
