Jakob Antriebstechnik Metal Bellows Coupling

1、 Core Model Series and Technical Parameters

1. KM series standard metal bellows coupling

   As a classic standard model of the brand, the KM series adopts a 6-wave corrugated tube structure, matched with double-sided EASY Clamp clamping wheels, easy to install, and is the main model for universal servo transmission scenarios. The product has a torque range of 20-1300Nm, suitable for shaft diameters of 8-85mm, and a working temperature of up to 200 ℃. It has excellent torsional rigidity and deviation compensation ability, and is widely used in machine tool feed drive, general mechanical transmission and other scenarios.

2. KP series short compact metal bellows coupling

   The KP series adopts a 4-crack corrugated tube design, with a more compact overall structure and shorter installation length. It can achieve high torsional rigidity transmission requirements in a limited space, with a torque range covering 25-900Nm, suitable for shaft diameters of 10-75mm, and also supports a working temperature of 200 ℃. It is suitable for automation equipment, precision detection instruments and other scenarios with limited installation space.

3. KR series low resilience metal bellows coupling

   The KR series adopts a straight corrugated tube structure with longer compensation stroke, which can achieve lower restoring force, reduce additional load on bearings, and maintain high torsional rigidity. The product has a torque range of 25-1500Nm, suitable for shaft diameters of 8-85mm, with outstanding angular compensation ability. It is also suitable for transmission scenarios with high difficulty in aligning shafts and continuous axial displacement.

4. KPH/KMH/KRH series stainless steel anti-corrosion coupling

   This series is designed with all stainless steel material and adopts a split type wheel hub structure on both sides, which is easy to install and has excellent anti rust and anti-corrosion capabilities. It can adapt to humid and corrosive working environments, with a torque range of 10-900Nm and a suitable shaft diameter of 6-55mm. It supports customized length adjustment and is widely used in food and medicine, chemical equipment, outdoor work machinery and other scenarios.

5. WD/WDS series long-distance metal bellows coupling

   In response to the transmission requirements of large shaft spacing, Jakob has launched the WD/WDS series long-distance couplings, which can achieve ultra long distance torque transmission of 0.2-6m with customized length intermediate pipes, without the need for additional intermediate support structures. The WD series has a working temperature of 90 ℃, while the WDS series high-temperature resistant version can reach 200 ℃. The torque range covers 15-1600Nm and is compatible with shaft diameters of 6-85mm. It is widely used in conveying equipment, multi axis synchronous transmission systems, and other scenarios.

2、 Core product features and advantages in adapting to working conditions

1. No backlash precision transmission

   The entire series of products adopt a force locking shaft wheel hub connection method, combined with precision machined metal corrugated pipes, to achieve torque transmission without backlash throughout the entire process. The transmission response speed is fast, the repeated positioning accuracy is high, and it is suitable for the high dynamic and high-precision transmission requirements of servo systemsThe Jakob group..

2. High torsional rigidity and low moment of inertia

   The metal corrugated tube is made of high elasticity stainless steel material and is integrally formed, with torsional rigidity. At the same time, the wheel hub is made of high-strength aluminum alloy or stainless steel material, which effectively reduces the moment of inertia while ensuring structural strength. It is suitable for high-speed and frequent forward and reverse transmission scenarios, and supports speeds up to 10000rpm.

3. Excellent adaptability to working conditions

   The product can adapt to a wide temperature range of -40 ℃ to 200 ℃ working environment, and special models can adapt to high temperature conditions of 350 ℃. At the same time, customized designs such as anti-corrosion, explosion-proof, and anti-static can be provided according to requirements to meet the needs of special working conditions such as semiconductor clean workshops, chemical, metallurgical, etc.

4. Convenient installation and maintenance

   The entire series comes standard with radial clamping wheel hub design, which does not require additional axial positioning, making installation and disassembly convenient. At the same time, the product has no vulnerable parts and does not require frequent maintenance under normal working conditions, effectively reducing equipment maintenance costs and improving equipment operation continuity.
