A differential reducer that employs trochoidal gears and thin cross roller bearings, achieving high precision, high rigidity, and an ultra-flat shape!
The "PSR/PSL series" is an ultra-thin differential gearbox that incorporates a precise and robust differential reduction mechanism. Inside the rollers arranged on the circumference, two robust and precise trochoidal gears are positioned opposite each other in an ultra-thin form, and through a clever pin-and-hole reduction mechanism and cross roller bearing support, it outputs a sophisticatedly designed ultra-thin differential gearbox. Additionally, the PSL series achieves approximately 30% weight reduction compared to the PSR by using aluminum materials for its components. 【Features】 ■ Ultra-flat & compact ■ Extremely high rigidity ■ High precision and precise positioning with backlash of 3 arcmin or less ■ Maintenance-free ■ High transmission accuracy, smooth operation, and high efficiency ■ Easy installation with attachments for various servo motors *For more details, please refer to the PDF materials or feel free to contact us.
