商标纸门磁力联轴器的设计

Design of Trademark Paper Door Magnetic Coupling

摘要: 针对商标纸门传动联轴器机械磨损展开研究，采用磁性联轴器替换机械联轴器，利用的是磁性物质同性相斥、异性相吸的原理，通过磁耦合构成一个非接触、无摩擦的传递扭矩机构，有效地解决了由于机械联轴器的磨损导致传动不稳定，出现商标阻塞的问题。本研究主要确定替换商标纸门处的机械式联轴器的磁力联轴器的耦合类型，并通过运用Ansoft工程电磁场有限元分析软件确定了磁力联轴器的磁极对数，输出了端面耦合式磁力联轴器的转矩特性曲线。

Abstract: The mechanical wear of paper door coupling was studied, using Magnetic coupling to replace the mechanical coupling. Based on the principle that magnetic substances repel each other and attract each other, a non-contact and frictionless torque transmission mechanism is formed through magnetic coupling, which effectively solves the problem of transmission instability and trademark blockage caused by the wear of mechanical coupling. This study mainly determines the coupling type of magnetic coupling to replace the mechanical coupling at the trademark paper door, and determines the magnetic pole logarithm of the magnetic coupling by using Ansoft engineering electromagnetic finite element analysis software, and outputs the torque characteristic curve of the end face coupling magnetic coupling.
