Reduce Lost Motion, Increase Stiffness, and Improve Feedback Accuracy
Whether you’re positioning a robotic arm, aligning an optical system, or controlling a medical device, positioning accuracy depends on more than just one component. Timken Precision Drives combines precision gearing, encoders, and engineering expertise to help you build motion systems with exceptional accuracy, repeatability, and reliability.
Why it Matters
Precision begins with the entire motion system.
Positioning errors can affect product quality, cycle time, process consistency, and the ability to perform demanding automated tasks. Backlash, compliance, transmission error, and feedback uncertainty can prevent an axis from reaching the commanded position consistently, particularly during reversals or changing loads.
Improving accuracy requires the gearing, bearings, motor, feedback device, controls, and surrounding structure to work together as a system.
What influences positioning accuracy?
Control Lost Motion
Backlash and other sources of lost motion create a difference between commanded movement and actual output movement. Low or zero backlash gearing can improve positioning performance, particularly when an axis frequently changes direction.
Increase System Stiffness
Torsional and tilting stiffness help the system resist deflection under load. Greater stiffness supports more stable positioning and can reduce settling time after acceleration or deceleration.
Improve Feedback Quality
Encoder resolution, accuracy, mounting, air gap, and placement all influence the quality of position data. The feedback device must measure the motion that matters, with sufficient accuracy for the application.
Optimize the Complete System
Motor sizing, gear ratio, bearing selection, structural rigidity, controller tuning, and feedback placement all contribute to final positioning performance. System-level engineering can reveal errors that component specifications alone do not show.
