Germany KTR GmbH coupling, KTR GmbH model, KTR GmbH price

KTR GmbH couplings connect several diaphragm packs (stainless steel thin plates) to the two coupling halves with bolts in an alternating arrangement. Each diaphragm pack consists of multiple stacked discs. The diaphragms are available in link-type and one-piece designs of various shapes. Diaphragm couplings compensate for the relative displacement of the two connected shafts through the elastic deformation of the diaphragms. They are high-performance, flexible metallic element couplings that require no lubrication, feature a compact design, high strength, long service life, and zero rotational backlash. They are unaffected by temperature or oil contamination, offer acid, alkali, and corrosion resistance, and are suitable for shaft drive systems operating under high temperatures, high speeds, and corrosive media.

KTR GmbH Coupling Introduction

Using just one mechanical torque limiter can quickly disconnect the motor from the main spindle, thereby eliminating the destructive effects of inertial forces. For ordinary machinery, including conveyor drives, office equipment, and various instruments, mechanical torque limiters such as shear-pin safety couplings and friction clutches provide good safety protection. However, they still cannot meet the requirements of high-performance equipment such as machine tools. One problem faced is that ordinary clutches and couplings transmit both torque and misalignment to the protected shaft. In special applications, there are other issues as well. However, safety couplings are a new type of mechanical torque limiter that overcomes these traditional problems. Safety couplings are best suited for protecting high-speed, high-precision drive units from overload damage. This type of coupling is not merely a refined version of ordinary torque limiters, but a product specifically designed in collaboration with machine tool manufacturers to meet certain specific requirements. Protection devices equipped with safety couplings are also lower in cost. When equipping machining centers with this type of protection device, each axis generally costs 750 USD.

KTR GmbH Coupling Features

All safety couplings have the following characteristics: 1) No backlash in keyless shaft-hub connections; 2) High torsional stiffness, very low moment of inertia, small size, and adjustable disengagement torque; 3) Maintains original position after re-engagement; 4) Provides alarm during overload; 5) Available in automatic and non-automatic re-engagement types, with heat resistance (above 260°C). In addition, certain types of safety couplings can compensate for axial, lateral, and angular shaft misalignments. Some models also feature integrated ball bearings on pulleys and sprockets. These characteristics make safety couplings not only well-suited for machine tool drives, but also for high-performance assembly lines, printing machinery, packaging machinery, etc. The internal-expansion friction safety coupling is a structural type of friction safety coupling. It uses two cylindrical helical springs to press arc-shaped friction plates against an intermediate ring, generating friction between the plates. The magnitude of this friction determines the coupling's slip torque. The slip torque is adjusted by replacing the springs. When the transmitted torque exceeds the slip torque of the R+W coupling, slippage occurs between the driving and driven sides; when the transmitted torque falls below the slip torque, the two sides stop slipping relative to each other and automatically return to normal operation. Under normal operating conditions within the specified range, component replacement is generally not required. With proper use of the AMN type internal-expansion friction safety coupling, impact loads during startup of the shaft drive system can be effectively partially mitigated, enabling uniform acceleration of the machine, while also preventing motor burnout due to overload. It can be used in conditions requiring overload safety protection to avoid damage to critical components. The internal-expansion friction safety coupling is a type of flexible safety coupling with elastic elements. It connects two halves of an R+W coupling via a double-row roller chain. Relative slippage can occur between the sprocket and the friction plates, providing safety protection. The torque is determined by the compression of the disc springs. It is suitable for connecting drive shaft systems with coaxial and parallel axes, offers certain compensation for relative shaft misalignment, limits torque, and provides overload protection.

KTR GmbH Coupling Applications

The features and applications of safety couplings are analyzed as follows: 1) Wide torque control range and high control precision. Torque is proportional to the excitation current over a wide range, allowing for complete and simplified control of transmitted torque, and it can be used as a linear regulation element. 2) Constant torque characteristic: torque depends solely on the magnitude of the excitation current and is independent of the relative speed between the driving and driven sides, exhibiting a constant torque nature where static torque equals dynamic torque. 3) Can transmit a certain torque regardless of slip difference, without shock, vibration, or noise, ensuring smooth operation, making it suitable for high-frequency operating conditions. 4) Low power consumption and low control power. The residual torque when excitation current is disconnected is very small, offering good disengagement performance. No heating occurs during idling, and torque stability is good, making it suitable for precise control. 5) Simple structure, small volume, and light weight. The magnetic powder is dry and oil-free, making maintenance easy. The magnetic powder has good oxidation resistance, heat resistance, long service life, and high reliability. By fixing the driven part, the torque becomes a braking torque on the rotating part, turning it into a magnetic powder coupling, which can also serve as a magnetic powder load brake.
