The invention relates to the technical field of door and window pulleys, in particular to a pulley device and a door and window pulley system.The pulley device comprises a mounting base, a pulley support is arranged on the mounting base, the pulley structure comprises a supporting shaft and a pulley, the pulley is arranged on the supporting shaft in a sleeving mode, and the supporting shaft is arranged on the pulley support; wherein the friction coefficient between the pulley and the supporting shaft is mu1, the friction coefficient of the peripheral side end face of the pulley is mu2, and mu1 is smaller than mu2. Compared with the prior art, by controlling the friction coefficient between the pulley and the supporting shaft to be smaller than the friction coefficient between the peripheral end face of the pulley and the contact face of the door and window frame, the friction force of the pulley in the rotating process is reduced, the sliding efficiency is improved, and stable rotation of the pulley on the supporting shaft is ensured; the contact between the pulley and the door and window frame is more stable and smoother; furthermore, durability of the pulley is improved, noise and abrasion are reduced, cost is lower, manufacturing is easier, and cost is lower.
本发明涉及门窗滑轮技术领域，具体涉及一种滑轮装置及门窗滑轮系统，包括安装座，滑轮支架设置在安装座上，所述滑轮结构包括支撑轴和滑轮，所述滑轮套设在支撑轴上，所述支撑轴设置在滑轮支架上；其中，所述滑轮与支撑轴之间的摩擦系数为μ1，所述滑轮的周侧端面的摩擦系数为μ2，所述μ1小于μ2。本发明的有益效果在于，与现有技术相比，本发明通过控制滑轮与支撑轴之间的摩擦系数小于滑轮周侧端面与门窗框架接触面的摩擦系数，降低滑轮在旋转过程中的摩擦力，提高滑动效率，确保滑轮在支撑轴上的稳定旋转，使滑轮与门窗框架之间的接触更加稳定和顺畅；进一步地，提高滑轮的耐用性，减少噪音和磨损，且成本更低，制造更容易成本更低。
