AI Technical Summary

Technical Problem

The guide rails of the existing shuttle rack are removable and installed during use, making it difficult to ensure firmness and position accuracy, resulting in friction resistance and wear problems.

Method used

The self-lubricating and wear-resistant annular guide rail body is adopted. Through the joint between the bite block and the bite hole and the annular connection part and the installation cavity, the guide rail made of polyether etherketone composite material is combined to achieve a firm connection and high-precision position of the guide rail. Adopt oil-free self-lubricating design.

Benefits of technology

It improves the position accuracy and stability of the guide rails, reduces wear and tear between the outer shuttle rack and the inner shuttle rack, extends service life, and achieves oil-free self-lubricating, reducing resource consumption and pollution risks.
