无油润滑压缩机活塞环和支承环设计

Design of the piston ring and support ring in without oil lubricated air compressor

通过对填充聚四氟乙烯材料活塞环及带卸荷槽结构支承环的研究 ,确定了活塞及活塞环结构 ,建立了带卸荷槽支承环的力学分析模型 ,并将其结果用于结构尺寸的确定。在压缩机工艺指标不变的情况下 ,用该方法设计的活塞环和支承环性能优良。

According to study on the piston ring made of polytetrafluoroethylene and support ring with load discharging groove, the mechanical analysis model of supporting ring with load discharging groove was established When the working condition of the compressor remain unchanged, excellent performances of the above mentioned piston ring and support ring can be obtained
