      [ ! ] Excellent in high torque / high speed rotation applications.
      [ ! ] When lateral misalignment is more than 0.1, spacer wear will be in proportion to the amount of load torque, lateral misalignment, and rotational speed.
      [ ! ] The moment of inertia is the magnitude of the rotatory inertia of a coupling. The higher this value increases, the larger rotatory inertia becomes.

      Coupling Selection and Handling

      (2) Calculate the compensation torque applied to coupling
      ●Connection with Servo Motors / Stepping Motors (For motion control)
      Calculate the Compensation Torque by multiplying Compensation Factor with the Motor's Peak Torque.
      *For Compensation Factor, please see product specifications in the product page.
      Choose a coupling with the torque capacity (shaft slip torque) higher than the calculated compensation torque.
      Compensation Torque = Motor's Peak Torque × Compensation Factor
      ● Connection with General-purpose Motor (For power transmission)
      ※* Calculate the load torque, and the compensation torque should be 1 to 5 times of the load torque.
      Choose a coupling with the torque capacity (shaft slip torque) higher than the calculated compensation torque.
      Load Torque(N・m)=9550× Transmission Power(kW) Rotational Speed (r/min)
      Compensation Torque = Load Torque (N⋅m) × 1 to 5

      (3) Check coupling tolerance
      Check that the Tolerance (Angular and Lateral misalignments and Max. Rotational Speed)
      and Max. Rotational Speed) and the Moment of Inertia mentioned in the catalogue meet the conditions of the device.
      (4) Select shaft bore
      Check if the outer diameter of the connecting shaft is included in the inner diameter range of the coupling.
      If the outer diameter is not included, select a larger size.
      (5) Select shaft connection method
      Select in accordance with the clamp, keyed locking, keyless clamping applications.
      (6) Final confirmation
      Finally check the dimension table to confirm that the coupling is compatible with the device.

      Design Overview

       

      Description/Basics

      A shaft coupling, also called a compensating coupling, is generally used for the transmission of torque for mechanical engineering. Flexible shaft couplings (non-rigid) can compensate for lateral, axial and angular offsets (misalignment). Therefore, these are common connecting elements between motors and axles/shafts or even ball screws.

      There are various types of designs, such as the jaw couplings, disc couplings (servo couplings), slit couplings, bellow couplings, Oldham couplings and many others, which are selected depending on the type of misalignment. You can determine which design is the right one for transmission in your application with the Coupling Selection Method available as a PDF.

      When the shaft coupling is professionally installed, the transmission of rotational forces should be slip-free. To do this, the appropriate shaft coupling must be selected depending on the application. Here, it is important to observe the degree of misalignment, the maximum speed of rotation and the permissible torque of the compensation coupling and not to exceed these values during operation. If several misalignments occur at the same time, it is recommended to reduce the maximum value of the specified misalignment by approximately half.

      The most commonly used elastomer coupling is the jaw coupling, which consists of a plastic buffer with damping properties. As a result, shocks and vibrations in a drive system can be damped, which protects adjacent components in the transmission of force. Our product range offers you alternative materials for the elastomers. These include among others aluminum bronze and carbon fibre-reinforced plastic.

      The different shaft connections on the compensation couplings allow various connection variants for assembly. For this purpose, hub clamping, half shell clamping, slot clamping, threaded pin clamping, chip sleeve and keyways are available.
      If a keyway is selected for a MISUMI shaft coupling, it is recommended obtaining the MISUMI machine key, as it is best to combine these.

      A shaft coupling can be used for precise positioning. These are often combined together with slide screws or ball screws. A disc clutch (servo coupling) is suitable for this application, since it has a high torsional rigidity.

      In addition to the standardized diameter of the shaft bore, MISUMI offers the option LDC and RDC, which allows the drill diameter to be adjusted to the shaft end in 0.1 mm increments.
