AI Technical Summary

Technical Problem

In existing tension roller structures, the tension roller mandrel and expandable bladder have multiple installation interfaces, large axial dimensions of the mandrel, and inconvenient quick-change connectors that are difficult to install, disassemble, and maintain, resulting in complex structures that are prone to oil leakage and pressure disturbance.

Method used

The variable tension roller structure with integrated valve block is adopted. By integrating the oil inlet valve block and the oil return valve block on the tension roller spindle, it is connected to the independent cavity of the expandable bladder through quick-change connector and fixed by bolts, which simplifies the installation process, reduces the number of deep holes, and realizes distributed pressure regulation.

Benefits of technology

It improves the feasibility and reliability of the assembly process, avoids difficulties in installation and disassembly, reduces oil leakage and pressure disturbance, simplifies the structure, and improves the stability of the tension roller system.

Abstract

本发明提供的一种阀块集成式变张力辊结构及装配方法,其中的可膨胀囊体中独立腔体的进油口、回油口分别通过快换接头与进油阀块、回油阀块连接,张力辊芯轴内的进油回路与进油阀块和回转接头上的进油孔连通,同时张力辊芯轴内的回油回路与回油阀块和回转接头上的回油孔连通,然后回转接头的进油孔、回油孔与液压系统连通,上述结构可实现两步式的安装,避免了可膨胀囊体与张力辊芯轴的连接、拆卸困难的问题,提高了装配工艺的可行性;同时实现了可膨胀囊体中各个独立腔体的调压,改变传统通过外部油路对多通道的可膨胀囊体独立腔体的压力调控,有效减少张力辊芯轴内部深孔数量,进而避免了张力辊芯轴和多路回转接头存在的漏油及多路扰动问题。
