MK1-5-23-5-6 coupling Germany R+W model MK1-5-23-5-6 price

MK1-5-23-5-6 coupling is a component that connects the prime mover to the driven machine. Its main function is overload protection. The torque limiter restricts the torque transmitted by the drive system in the form of slippage when the required torque exceeds the set value due to overload or mechanical failure. It automatically restores the connection after the overload condition disappears. This prevents mechanical damage and avoids costly downtime losses.

MK1-5-23-5-6 coupling introduction

Using only one mechanical torque limiter can quickly disconnect the motor from the main shaft, thereby eliminating the destructive effect of inertial forces. For ordinary machinery, including conveyor drives, office machinery, 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. However, the safety coupling is a new type of mechanical torque limiter that overcomes the aforementioned traditional problems. Safety couplings are most suitable for ensuring that high-speed, high-precision drive units are protected from overload damage. This coupling is not merely a refined version of ordinary torque limiters, but a product specifically designed in cooperation with machine tool manufacturers to meet certain specific requirements. The price of protection devices with safety couplings is also relatively low. When equipping machining centers with this type of protection device, each axis generally costs 750 USD.

MK1-5-23-5-6 coupling features

All safety couplings have the following characteristics: 1) No backlash in keyless shaft hub connections; 2) High torsional rigidity, very low moment of inertia, compact 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 feature integrated ball bearings on pulleys and sprockets. These characteristics make safety couplings not only suitable 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 via an intermediate ring, generating friction between the plates. The magnitude of this friction determines the sliding torque of the coupling. The sliding torque of the coupling is adjusted by replacing the springs. When the transmitted torque exceeds the sliding torque of the AMN coupling, slippage occurs between the driving and driven sides; when the transmitted torque is lower than the sliding torque, there is no relative slippage between the two sides, and normal operation is automatically restored. 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 transmission system can be effectively partially mitigated, enabling uniform acceleration of the machine, while preventing motor burnout due to overload. It is suitable for operating 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 the AMN coupling with 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 amount of the disc spring. It is suitable for connecting transmission shaft systems with coaxial and parallel axes, has certain compensation capability for relative shaft misalignment, limits torque, and provides overload protection.

MK1-5-23-5-6 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 fairly wide range, allowing for perfect and simplified control of transmitted torque, and it can be used as a linear regulation element. 2) Features 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. It has a fixed torque characteristic, with static torque equal to dynamic torque. 3) Can transmit a certain torque regardless of slip difference, without shock, vibration, or noise. Operation is smooth, making it suitable for occasions with high operating frequencies. 4) Low power consumption and low control power. The residual torque when excitation current is disconnected is very small, offering good disengagement performance. There is no heating phenomenon 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 it easy to maintain. 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, forming a magnetic powder coupling, which can also serve as a magnetic powder load brake.
