Problems solved by technology

The rotary encoder of the present application is not limited to the working environment, and has good anti-interference performance. It can not only accurately measure the rotation angle of the rotary device in the harsh working environment, but also reduce the production cost of the encoder.” However, in this patent, the rotary The interior of the encoder lacks the auxiliary lubrication of the rotating structure, resulting in high wear caused by the internal rotation, which affects the speed and thus affects the use of the device

Abstract

The invention discloses a built-in rotary encoder for detecting the rotation speed, which comprises a connecting seat, a base and a rotating shaft. The bottom of the connecting seat is provided with the base, the top of the base is provided with the rotating shaft, the top of the connecting seat is provided with an upper bearing, and the top of the upper bearing is connected to the bottom of the outer surface of the rotating shaft; a connecting shaft is connected to the middle of the outer surface of the rotating shaft, a coding disc is mounted in the middle of the outer surface of the connecting shaft, and a mounting base is arranged on one side of the top of the coding disc. Through the arrangement of the coding disc and a speed measurement module, after a power line assembly is connected with an external power source, the whole device is driven to work, the coding disc works along with rotation of the rotating shaft, when the rotating shaft works, the speed measurement module can synchronously carry out speed measurement work, and therefore the speed measurement function of the device is added; and a light detector, a light source assembly, a photoelectric emission unit and a photoelectric receiving module are arranged in the device work, so that the whole device is driven to work normally.

Description

technical field [0001] The invention relates to the technical field of rotary encoders, in particular to a rotary encoder with built-in detection of rotation speed. Background technique [0002] Existing encoders are used to compile signals and data and convert them into multiple signal forms. They have a wide range of applications, and people have different needs for them. After the encoders generate electrical signals, they are set by CNC and programmable by the numerical control. Logic controllers PLC, control systems, etc., these sensors are mainly used in the following areas: machine tools, material processing, motor feedback systems, and measurement and control equipment. The conversion of angular displacement in the ELTRA encoder adopts the principle of photoelectric scanning. The reading system is based on the rotation of the radial indexing disk. The indexing is composed of alternating light-transmitting windows and opaque windows. This system uses an infrared The ...
