Description

Anti-vibration encoder

Technical Field

The utility model belongs to the technical field of encoder assembly technique and specifically relates to indicate a antivibration encoder.

Background

An encoder (encoder) is a device that compiles, converts, and formats signals (e.g., bitstreams) or data into a form of signals that can be communicated, transmitted, and stored. Encoders convert angular or linear displacements, called codewheels, into electrical signals, called coderulers. The encoder can be divided into a contact type and a non-contact type according to a reading mode; encoders can be classified into an incremental type and an absolute type according to their operation principles. The incremental encoder converts displacement into periodic electrical signals, and then converts the electrical signals into counting pulses, and the number of the pulses is used for expressing the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so that its representation is only dependent on the start and end positions of the measurement, and not on the intermediate course of the measurement. The existing encoders are various in types, but the existing encoders are generally poor in vibration reduction effect and greatly influenced by external interference.
