Max. permissible inertia J*
Dimensions and maximum loads
The indicated moments and forces are statical values and may appear simultaneously. Throttling has to be done for ensuring that the rotary movement takes place without impact or bouncing. Otherwise the service life reduces.
Max. permissible inertia J*
- X-axis:
- Swiveling time
- Y-axis:
- Mass moment of inertia
- X-axis top:
- Cycles per hour
*The diagrams are valid for basic units and for applications with a vertical swivel axis as well as for absolutely centric loads with a horizontal swivel axis and with an operating pressure of 6 bar. The swiveling times per throttling have to be observed, otherwise the life time may reduce. We will be happy to help you designing other applications. In addition, the SCHUNK Swiveling product finder is available online.
产品系列的常规说明
重复精度
定义为 100 个连续回转循环后极限位置分布。
齿轮轴位置
始终显示在左端位置。齿轮沿着顺时针方向从这个位置向右转动。箭头表示旋转方向。
终端位置扭矩
注意采用单个传动活塞的力才能靠近重点位置前的最后角度（约 2°）。因此，双压力模块扭矩仅采用此区域可用的约额定扭矩的一半。可采用外部止挡在终端位置均匀达到最大扭矩。
朝气动中间位置旋转
仅通过一半的额定转矩完成。
回转时间
小齿轮/法兰围绕标称旋转角旋转的时间。不包括阀门开关时间、软管注入时间或 PLC 反应时间，但是计算周期时必须考虑这些时间。
外壳材料
铝（挤压型材）
启动
气动，带符合 ISO 8573-1:2010 [7:4:4] 的过滤压缩空气。
工作原理
双活塞齿条和小齿轮原理
标配范围
流量控制阀、定心套、直接接口 O 型圈，带肩螺栓（仅 SRU-plus 63）、装配和操作手册（带制造商声明）
保修期
24 个月
