Off-axis absolute value encoder

The invention relates to the technical field of motor encoders, and discloses an off-axis absolute value encoder, which comprises a flange plate and a base, the base is fixed on the flange plate, a bearing frame is fixedly arranged on the base, a code disc and a PCB (Printed Circuit Board) are arranged between the base and the bearing frame, a shaft sleeve is arranged in the middle of the base, the code disc is fixed on a wing edge of the shaft sleeve, and the bearing frame is fixed on the shaft sleeve. An expansion ring and a locking nut are arranged in the shaft sleeve, the PCB is fixed on the bearing frame, bearings are arranged at two ends of the shaft sleeve, the bearings are respectively fixed on the base and the bearing frame, and the expansion ring is locked by the locking nut. Off-axis coaxial holding flexible connection is adopted, an ultra-thin and ultra-small structure is achieved, installation is convenient, and precision is high. 本发明涉及电机编码器技术领域，公开了一种离轴式绝对值编码器，包括法兰盘、基座，所述基座固定在法兰盘上，所述基座上固定设置轴承架，在基
