In order to solve the problems of high loss,short service life,poor anti-vibration ability and low reliability of the existing incremental encoder controlled by shaft handle,a design scheme of incremental photoelectric encoder with optical-mechanical-electrical integration is introduced,including innovative designs such as 32-inner petal shaft sleeve and retractable ball positioning,Z-shaped light-shielding disc design and infrared photosensitive OC open-circuit output circuit.Through precise struc-tural design and material selection,high-precision 32-gear electrical signal conversion is realized.The structural reliability is verified by three-dimensional modeling and finite element analysis.By comparing with the technical indexes of foreign similar products,the data and the environmental adaptability are verified.The study has advantages in performance,structure and cost,and has broad application prospects.
