Coupling terminology

Everything has its own specialized terminology in the industry. For example, a computer has a professional term for a computer. As a component of a machine, a coupling, of course, also has professional terminology. Here, I will explain the terminology of a coupling.

      ◆Rated torque: refers to the torque capacity that the coupling can continuously transmit.The variable load factor during operation has been considered, so there is no need to adjust the rated torque.Please select a coupling with a rated torque higher than the continuous operating load torque.   

      ◆maximumTorque: refers to what the coupling can transmit instantlymaximumTorque capacity, also called peak torque, is in principle twice the rated torque.   

      ◆highestNumber of revolutions: refers to the available couplinghighestWhen rotating at high speed, please pay attention to the vibration caused by unbalance.   

      ◆ Moment of inertia: refers to the difficulty of rotation of the coupling. The smaller the moment of inertia, the smaller the load torque when starting and stopping.   

      ◆Static torsional rigidity: refers to the rigidity of the coupling against torsion. The greater the static torsional rigidity, the higher the response of the product.   

      ◆Backlash value: refers to the amount of clearance existing in the rotation direction of the coupling. For high-precision positioning devices, please select a coupling with zero backlash value.    

      ◆Applicable temperature: refers to the temperature range within which the coupling can be used.   

      ◆ Deviation adjustment: Refers to the position accuracy error of the axis, which can be divided into three types: eccentricity, deflection angle, and axial deviation.   

      ◆Eccentric reaction force: refers to the force generated by the assembly eccentricity of the coupling. The smaller the eccentric reaction force, the smaller the force that the bearing will bear.   

      ◆Axial reaction force: refers to the force generated when the coupling is axially compressed. The smaller the axial reaction force, the smaller the force that the bearing will bear.   

      ◆Natural frequency: refers to the resonance number of the coupling.
