5ZV25J-10160窄V胶带失效原因及改进措施

对川南矿区使用的5ZV25J－10160联组窄V胶带的损坏情况进行了观察分析，主要损坏原因有：胶带V形夹角与带轮轮槽夹角不一致，胶带顶部宽度与带轮轮槽开口宽度不符合要求，在传递动力中造成带轮顶部与胶带联结层接触而单根胶带悬空；胶带硫化质量差、配组不当；胶带及带轮安装、调校未达到要求。对此提出如下改进措施：规定胶带V形夹角和带轮轮槽夹角均为40°，单根胶带顶部宽25mm，带轮轮槽开口宽23．4mm；胶带必须严格按规定配组、安装、调校。实践证明，经改进后胶带传动平稳，无异常损坏。

Failure causes and improvement of Model 5ZV25J-10160 narrow V-belt

Analysis of failure of Model 5ZV25J-10160 narmw V-belt used in South Sichuan Oimeld shows that the causes ofthe failure of the rubber belt include: V-shaped included angle of the belt being nonidentical to the angle of the beltwheel shecve; both the width of the belt top surface and the belt wheel sheeve open width not according with require-ments; singe belt being suspended in operation; helt quality being low and improper matching being adopted; installationand adjustant of belt and belt wheel being unsatisfactory. Improving measures are offered: both V-shaped included an-gle of helt and angle of belt Wheel sheeve being 40°, the top width of a single belt being 25mm, the open width of thebelt wheel shceve being 23 .41mm, belts matching, installation and adjustInent being carried out according to relevant reg-ulations. Practice shows that the improved belt operates smoothly without any failure.
