AI Technical Summary
Existing absolute encoders have a shortened service life under vibration due to their thin brackets and flexible connections, and the spring couplings are easily damaged by iron oxide scale.
It adopts a combination structure of perforated flange, spring coupling and bushing, and is rigidly connected to the reducer by 6 hexagonal bolts. Combined with the reinforcement structure of positioning plate and tension block, a rigid connection is formed, which protects the spring coupling and isolates iron oxide scale, so as to realize installation and disassembly.
It improves the service life of encoders and spring couplings, enhances equipment stability, reduces maintenance frequency, and avoids damage caused by vibration.
