产品概述

通过设计膜片紧固部分的高刚性柔性联轴器。
[特征]
・轴径φ12（直径12mm）～φ50（直径50mm）的10种型号、45种尺寸标准化。
-由于膜片紧固部分的独创性，因此具有高扭转刚度。
・允许偏角和末端间隙。
・转动惯量较小。
[利用]
・机床、精密平台等。

产品特点

组装时可自由选择联接类型，适用扭矩最大可达689N·m。

尺寸图

注意事项

静态扭转刚度、惯性力矩、重量为最大轴径时的值。

偏心、偏角、轴向振幅均为单项容许值。如果同时出现多种偏差，则各种偏差的容许值减小为原来的1/2。

有关选型基准及校准调整，请参阅

P.788·789。

单膜片型不允许偏心。
