Abstract

The invention discloses an encoder and an installation method thereof. The encoder comprises an encoder support, a PCB embedded in the encoder support, a number reading head electrically connected to the PCB and a rotation assembly sleeving a rotation shaft of a motor. The rotation assembly is formed by assembling an optical grating support, an optical grating and a multi-pole magnetic ring. The multi-pole magnetic ring sleeves the lower end of the optical grating support. The optical grating sleeves the optical grating support and is arranged between the optical grating support and the multi-pole magnetic ring. U-type openings penetrating through the encoder support and the surface of the PCB are arranged in the same positions of the encoder support and the PCB. According to the invention, the encoder is highly reliable and universal, convenient to install and high in installation efficiency, so problem of poor reliability of the encoder caused by a reliability reason of the bearing is solved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of encoder structure design, and in particular relates to an encoder and an installation method thereof. [0003] 【Background technique】 [0004] With the development of science and technology and industrial automation, automatic control technology has been applied more and more in various fields. The servo system with the servo motor as the control object has gradually penetrated into all aspects of industrial production, scientific research and national defense. Various equipment (such as industrial robots, CNC machine tools and aerospace equipment, etc.) have higher and higher requirements for servo systems, such as: short response time, high stability of rotational speed and torque, and high positioning accuracy. One of the core factors for the servo system to meet the above high requirements is that the encoder installed on the servo motor should have high resolution, high precision and good op...
