AI Technical Summary

Technical Problem

Existing meter wheel encoders are prone to slippage when oil or particulate matter is present, leading to accumulated measurement errors, especially measurement delays and low accuracy during high-speed or directional movements.

Method used

The dual metering wheel encoder structure is adopted. Through the dual-wheel synchronous measurement mechanism, the measurement results of the metering wheel are cross-validated to eliminate the error caused by single wheel slippage. The design of sliding block and spring is used to improve measurement accuracy.

Benefits of technology

It effectively eliminates the accumulation of errors caused by single-wheel slippage, significantly improves measurement accuracy, and ensures that the distance of an object can still be accurately measured when moving at high speed or changing direction.
