MK1-100-53-10-12.7 coupling, Germany R+W, model MK1-100-53-10-12.7 price

The MK1-100-53-10-12.7 coupling is a mechanical component used to connect two shafts (driving shaft and driven shaft) in different mechanisms, enabling them to rotate together to transmit torque. In high-speed, heavy-load power transmission systems, some couplings also provide buffering, vibration damping, and improved dynamic performance of the shaft system. The coupling consists of two halves, each connected to the driving shaft and the driven shaft respectively. Generally, prime movers are connected to working machines via couplings.

MK1-100-53-10-12.7 coupling features

Due to its simple structure, low cost, and ability to transmit large torques, it is often used when the rotational speed is low, there are no impacts, the shaft rigidity is high, and alignment is good. A flange coupling (also known as a flanged coupling) connects two flange-type half-couplings using bolts; the two half-couplings are respectively keyed to the two shafts to achieve shaft connection, transmitting torque and motion. Flange couplings have a simple structure, are easy to manufacture, have lower costs, operate reliably, and are simple to install, disassemble, and maintain. They can transmit larger torques and ensure high alignment accuracy between the two shafts. They are generally used in shaft systems with stable loads, high speeds, or high transmission precision requirements. Flange couplings do not possess radial, axial, or angular compensation capabilities. If alignment accuracy of the connected shafts cannot be ensured during use, the service life, transmission precision, and transmission efficiency of the coupling will be reduced, causing vibration and noise. For rigid couplings, depending on the magnitude of the transmitted torque, all bolts on the flanges can be fitted bolts for reamed holes, or half can be fitted bolts and the other half ordinary bolts. Rigid couplings are lightweight, have low inertia, and extremely high sensitivity. In practical applications, rigid couplings are simple to maintain and resistant to oil and corrosion. In high-speed environments, they can compensate for relative displacement generated by high-speed operation. Of course, if relative displacement can be successfully controlled, they can also perform excellently in servo systems. [1 Structural forms of rigid couplings: A rigid coupling consists of two half-couplings with grooves on their end faces and an intermediate disc with teeth on both sides. Since the teeth can slide within the grooves, it can compensate for relative displacement between the two shafts during installation and operation. The rigid coupling also includes two shaft sleeves and a central steel shell, where the central steel shell is the torque-transmitting element. Above is the basic knowledge about rigid couplings shared with you, hoping to help users who have confusion in this area.

MK1-100-53-10-12.7 coupling relative motion

Rigid couplings are composed of rigid force-transmitting components. There is no relative motion between the connecting parts, so they do not have the ability to compensate for relative misalignment of the two shaft axes. They are only suitable for applications where the two connected shafts can be strictly aligned during installation and no relative offset occurs during operation. Flange couplings have no elastic elements, lack vibration damping and buffering functions, and are generally only suitable for operating conditions with stable loads and no impact vibration. Rigid couplings were formerly also called fixed rigid couplings, including flange couplings, radial key flange couplings, floating shaft couplings, clamp shell couplings, sleeve couplings, etc. Rigid couplings generally have simple structures and lower manufacturing costs. When selecting a rigid coupling, try to minimize the alignment error of the axes of the two connected shafts. To reduce the impact of additional loads on the coupling, try to minimize the distance between the coupling and the bearings. A flange coupling (also known as a flanged coupling) connects two flange-type half-couplings using bolts. Rigid couplings have two main structural forms: (1) achieving alignment of the two shafts using fitted bolts for reamed holes and transmitting torque through compression and shear on the bolt shanks; (2) achieving alignment by matching a shoulder on one half-coupling with a groove on the other half-coupling. The bolts connecting the two half-couplings can be ordinary bolts of grade A and grade B, with torque transmitted via the frictional moment on the mating surfaces of the two half-couplings. Materials for rigid couplings can be gray cast iron or carbon steel. For heavy loads or when the circumferential speed exceeds 30 m/s, cast steel or forged steel should be used.

MK1-100-53-10-12.7 coupling disassembly method

A professional manufacturer of rigid couplings teaches you the correct method for disassembling rigid couplings. Before disassembly, mark the mating positions of the various components of the coupling to serve as a reference for reassembly. For LingSi couplings used in high-speed machinery, the connecting bolts are weighed, and the markings must be clear and not mistaken. When disassembling the coupling, generally remove the connecting bolts first. Due to the deposition of oil sludge, corrosion products, and other deposits on the thread surface, bolts are difficult to remove, especially for severely rusted bolts, which are very challenging to disassemble. [The removal of connecting bolts requires selecting appropriate tools, because if the load-bearing surfaces of the external hexagon or internal hexagon of the bolt have slipped and been damaged, disassembly will be even more difficult. For bolts that are already rusted or have significant oil sludge, it is common to spray a solvent (such as a rust remover) onto the connection between the bolt and nut, allowing the solvent to penetrate into the threads, making it easier to disassemble the rigid coupling.
