Precision Motorized Stages with Roller Gear Drive is a high-precision electric linear/rotary motion execution device that uses column gear meshing transmission. It integrates a roller gear transmission mechanism, servo drive system, and precision guide components. With the multi-point contact transmission characteristics of gears and rollers, it achieves high-precision, high rigidity, and high load motion control. Precision Motorized Stages with Roller Gear Drive is a core component with strict requirements for transmission stability and positioning accuracy in high-end precision manufacturing, scientific research and testing fields. It balances transmission efficiency and impact resistance, and is suitable for precise motion requirements under complex working conditions.
Precision Motorized Stages with Roller Gear Drive's structural design focuses on high precision and high stability, with four key components at its core. The transmission core is a roller gear mechanism, which transmits power through multi-point meshing between gear teeth and precision rollers, replacing traditional gear line contact transmission. The contact area is increased by 3-5 times, greatly enhancing the load-bearing capacity and transmission stability. The driving unit adopts high-resolution servo motors, combined with precision encoders to achieve closed-loop control, and provides real-time feedback on the motion position to correct deviations. The guiding mechanism adopts high-precision linear guide or air floating guide to ensure the straightness of motion and the accuracy of repeated positioning. In addition, Precision Motorized Stages with Roller Gear Drive is equipped with an integrated rigid shell and dust-proof sealing structure to reduce vibration interference and adapt to harsh working environments. Some models can be equipped with shock absorption modules and pre tensioning adjustment devices to further optimize their performance.
Precision Motorized Stages with Roller Gear Drive advantages are particularly prominent.
Firstly, the positioning accuracy and repeatability are excellent. The uniform meshing of roller gears reduces transmission clearance, and the positioning error can be controlled within ± 1 μ m. The repeatability accuracy reaches ± 0.1 μ m, meeting the requirements of nanometer level precision motion.
Secondly, it has strong load-bearing capacity and high rigidity. The multi-point contact design significantly improves its impact load resistance, making it suitable for heavy-duty scenarios ranging from tens to hundreds of kilograms, with minimal deformation during long-term operation.
Thirdly, the transmission efficiency is high and the wear is low. The rolling friction of the rollers replaces the sliding friction, and the transmission efficiency reaches over 90%. The service life is 2-3 times longer than that of ordinary gear platforms.
In addition, it has low operating noise, fast response speed, and is suitable for high-frequency start stop and continuous operation conditions, significantly reducing maintenance costs.
