German BIKON coupling BIKON model BIKON price

BIKON couplings consist of components such as an internal gear ring and a flanged half-coupling with external teeth, both having the same number of teeth. External teeth are available in two profiles: straight teeth and crowned teeth. Crowned teeth refer to external teeth machined into a spherical surface, with the sphere's center on the gear axis. The backlash is larger than that of standard gears. Crowned tooth couplings allow greater angular misalignment (compared to straight-tooth couplings), improve tooth contact conditions, increase torque transmission capacity, and extend service life. During operation of gear couplings, relative displacement occurs between the two shafts, causing periodic axial sliding between the internal and external tooth surfaces, inevitably resulting in tooth surface wear and power loss. Therefore, gear couplings must operate under good lubrication and sealing conditions.

BIKON coupling manufacturing process

Jaw couplings are manufactured through machining processes such as turning, milling, and broaching, followed by overall heat treatment to ensure sufficient mechanical strength. Another type of jaw hub available on the market is cast, allowing for mass production and eliminating machining losses. Consequently, the price is much lower than that of machined versions. However, cast components do not perform well. It is best not to use them in critical applications. Furthermore, the jaws of cast hubs are prone to tooth breakage (jaw tooth detachment) under high speed or high load conditions. 1) Compact, zero-backlash, offering three different hardness elastomers; 2) Absorbs vibration, compensates for radial and angular misalignment; 3) Simple structure, easy maintenance, convenient inspection; 4) Maintenance-free, oil-resistant, electrically insulating, operating temperature 20℃-60℃; 5) Jaw elastomers are available in four-lobe, six-lobe, eight-lobe, and ten-lobe configurations; 6) Fixing methods include set screw, clamping, and keyway fixation.

BIKON coupling features

Elastomers are generally composed of engineering plastics or rubber. The service life of the coupling is determined by the service life of the elastomer. Since elastomers are subjected to compression rather than tension, their typical service life is 10 years. Due to their cushioning and vibration-damping properties, elastomers are frequently used in applications with strong vibrations. The performance limit temperature of the elastomer determines the operating temperature of the coupling, typically ranging from -35 to +80 degrees. Jaw couplings feature a simple structure, require no lubrication, are easy to maintain and inspect, are maintenance-free, and support continuous long-term operation. High-strength polyurethane elastic elements are wear-resistant and oil-resistant, offer high load capacity, long service life, and safe, reliable operation. They provide stable and reliable performance with good vibration damping, cushioning, and electrical insulation properties. They offer significant compensation capabilities for axial, radial, and angular misalignment. The structure is simple, with small radial dimensions, light weight, and low moment of inertia, making them suitable for medium to high-speed applications. Structural features: 1) Connected via a central elastomer. 2) Absorbs vibration and compensates for radial, angular, and axial misalignment. 3) Oil-resistant and electrically insulating. 4) Identical rotational characteristics in both clockwise and counter-clockwise directions. 5) Set screw fixation.

BIKON coupling selection

Jaw couplings mainly come in two types: the traditional straight-jaw type and the curved (concave) jaw zero-backlash coupling. Traditional straight-jaw jaw couplings are not suitable for high-precision servo drive applications. Zero-backlash jaw couplings evolved from the straight-jaw type, but their design is tailored for servo system applications, commonly used to connect servo motors, stepper motors, and ball screws. The curved shape reduces deformation of the elastic jaw spider and limits the impact of centrifugal force during high-speed operation. A zero-backlash jaw coupling consists of two metal hubs (typically made of aluminum alloy, with stainless steel also available) and a jaw elastic spider. The jaw elastic spider has multiple lobes. Like a slider coupling, it achieves fit between the spider and the hubs on both sides through compression, thereby ensuring its zero-backlash performance. Unlike slider couplings, which transmit torque via shear forces, jaw couplings transmit torque through compression. When using zero-backlash jaw couplings, users must ensure that the maximum load capacity of the elastic element specified by the manufacturer is not exceeded (while maintaining zero backlash). Otherwise, the jaw elastic spider will be compressed, deformed, and lose its elasticity, causing the preload to disappear and resulting in loss of zero-backlash performance. This may lead to serious issues that users might only discover later. Jaw couplings offer excellent balance performance and are suitable for high-speed applications (maximum speed up to 30000 rpm), but they cannot handle large misalignments, especially axial misalignment. Larger eccentricity and angular misalignment generate higher bearing loads compared to other servo couplings. Another concern is the failure mode of jaw couplings. Once the jaw elastic spider is damaged or fails, torque transmission is not interrupted; instead, the metal jaws of the two hubs engage directly to continue transmitting torque, which may cause system problems. Selecting the appropriate jaw spider material based on actual applications is a major advantage of this coupling. Some automation equipment companies offer jaw spiders made of various elastic materials with different hardness and temperature resistance, allowing customers to choose suitable materials to meet the performance standards of their specific applications.
