角度编码器
使用角度编码器测量角度
海德汉的角度编码器精度高,可达弧秒或更高。
典型应用有:
- 机床转台
- 机床转头
- 车床C轴
- 齿轮测试机
- 印刷机的印刷单元
- 分光计
- 望远镜
有三种不同的机械结构:
带内置轴承、空心轴和内置定子联轴器的角度编码器
由于定子联轴器的结构和安装原因,轴进行角加速度时,定子联轴器必须只吸收轴承摩擦所导致的扭矩。因此RCN、RON和RPN角度编码器具有出色的动态性能。对内置定子联轴器的角度编码器,技术参数中的系统精度已包括联轴器的偏差。:
更多优点
- 尺寸小,适用于安装空间有限的地方
- 空心轴直径可达100 mm,便于穿电源线等
- 车床C轴
- 安装简单
带内置轴承的角度编码器,采用分离联轴器
采用分离联轴器、实心轴的ROD角度编码器特别适用于轴转速高并要求较大公差的应用。高精度的联轴器允许± 1 mm以内的轴向运动。
无内置轴承的角度编码器
无内置轴承的ERA和ERO角度编码器(模块式角度编码器)适用于安装在机器部件或装置上。用于满足以下需求:
- 大直径空心轴(最大可达10 m的带尺)
- 轴转速高,最高可达40000 rpm
- 没有轴密封带
角度编码器带内置轴承
海德汉带内置轴承角度编码器的突出特点是系统精度高。 内置轴承的角度编码器消除了机床部件轴承对测量精度的影响。
RCN/RON/ECN系列角度编码器的内置定子联轴器最大限度降低联轴器误差导致的测量误差。 内置轴承角度编码器全部配轴密封圈,确保高抗污染性能(IP64防护等级)。 这些编码器适用于几乎各类机床,测量机,望远镜,印刷机等众多应用领域。
