The discussion centers on the effectiveness of encoders in measuring the correct rotational angle of a shaft that experiences movement in both X and Y directions, in addition to rotation. It is established that using couplings, such as Schmitt Couplings or double Cardan Joints, can help maintain accurate measurements despite the shaft's misalignment. The necessity of defining "correct rotation" is emphasized, as it influences the choice of coupling. Diagrams of the setup are recommended for better guidance.
PREREQUISITESEngineers, mechanical designers, and technicians involved in motion control systems, particularly those working with encoders and couplings in dynamic environments.
If the shaft is parallel to the encoder axis, but not coaxial, then you can use a Schmitt Coupling. Google Schmitt Coupling for simulations.Confused_Encoder said:Assuming I can get couplings to link the shaft to the encoder and the moving item, will the encoder always measure the correct rotation of the item whatever the X and Y position of the item is?
What is the orientation of the shaft. We need a diagram.Confused_Encoder said:The problem is that the other end of the shaft can move in X and Y (forward/backward and left/right) as well as rotate.
