Exlar® 的 FT 系列执行器使用安装在挤压铝制外壳内的行星滚柱丝杠。 这些电动线性执行器与各种标准电机兼容。 电机安装和齿轮配置可满足各种应用的要求。 标准产品提供四种框架尺寸,标准行程长度可达36英寸(914 mm),额定载荷可达40,000 lbf(177 kN)。
与所有 Exlar 滚柱丝杠执行器一样,与 acme 和滚珠丝杠解决方案相比,FT 系列具有高负载能力、高速度和超长的使用寿命。 在同等尺寸下,在中等到重负载下,您可以期望 FT 系列的工作寿命是其他解决方案的 15 倍。 更大的功率,出色的耐用性和更小的占地面积使FT系列成为液压系统的卓越电动替代品。

以下是给定输入电流占比连续额定电流百分比时,您的应用的最大允许占空比:
例如: 如果您的执行器的连续额定电流为 10 A,连续额定力为 1000 lbf,则意味着产生 1000 lbf 的力需要大约 10 A,产生 500 lbf 的力需要 5 A,依此类推。 如果您需要推动超过1000磅的重量怎么办? 在大多数情况下,您会考虑更强的定子或更大的致动器。 如果只有几秒钟呢? 您是否会过度使用当前的执行器? 答案是肯定的,计算多少并不难。
假设您需要推动1500 lbf。 这相当于10 A连续额定电流的1.5倍。 如果您看下面,图表建议在这种情况下占空比不超过22%。 这意味着您可以在15 A电流下运行执行器22%的时间而不会过热。 另外78%的时间,它需要关闭/冷却。
在峰值电流下可以运行多长时间?
不是一个简单的问题,也不是一个简单的答案。 实际上,影响这一点的因素有很多(系统是如何构建的,执行器散热的能力如何,是否有额外的散热器,空气中的颗粒,真空度,每次新的启动温度? (即并不总是从冷开始等)。 因此,精确的时间和温度很难估计。
例如: 在峰值电流(2x连续)时,允许的占空比为4%。 这并不意味着只要您有96个小时的休息时间,您就可以连续跑步4小时。 根据经验,我们估计的一个很好的经验法则是峰值电流运行时间为30秒到一分钟。 试着把它放在下面,然后当然让它冷却96%的时间。
我们经常被问及再润滑间隔。 现实情况是,没有通用的间隔来重新润滑执行器。 它取决于很多事情,每个应用和情况都不同,几乎不可能准确计算每个应用的再润滑间隔。 因此,我们有一个粗略的指南表(如下所示),让用户了解何时开始检查需要更换的旧污染润滑脂。 但是,由于环境温度,散热,速度变化,空气中的颗粒等可能因应用而异,因此这只是一个指南。 在此表建议的时间段内,应更频繁地检查致动器,一旦注意到润滑脂已准备好更换(脏污,污染/非常暗,充满颗粒/碎屑), 就可以确定重新润滑间隔。
请记住,润滑脂需要清理和更换 - 不要只是插入更多。 (除了FTX,在需要清理之前,它们可以处理5-6个润滑)

对我们来说,这是一个非常普遍的问题。 对于执行器本身来说,这很容易。 螺钉的机械导程精度通常为0.001 in/ft,这是任何类型的精密定位螺钉的典型规格。 这意味着在螺钉累积长度的任意点上,每英尺螺钉长度的最大变化为 0.001 英寸。 这与机械可重复性不同。 机械可重复性是螺钉从同一方向接近并驱动完全相同的匝数时,螺钉返回的相同线性位置的公差。 此值约为 0.0004 英寸。
电子定位分辨率是反馈装置和伺服放大器的功能。 假设我们在GSX30上有Exlar的标准编码器,滚柱丝杠上每转引线为0.2英寸。 Exlar 的标准编码器每转有 2048 条线路和 8192 个电子脉冲,可输出到伺服驱动器。 因此,在理想情况下,定位分辨率将为(0.2英寸/转)/(8192脉冲/转)或0.0000244英寸。 任何使用过伺服驱动器的人都知道,您不能定位到一个编码器脉冲。 让我们使用10个编码器脉冲作为合理的最佳定位能力。 这为我们提供了0.000244英寸的定位分辨率。
需要考虑的更多事项: 在考虑可重复性和准确性时,还必须考虑几个因素。 其中之一是系统的刚度。 刚度是系统在压缩力或拉伸力下拉伸或压缩的程度。 如果执行器的刚度和机械系统的刚度(包括所有联轴器、安装面等)的组合允许比系统所需的定位分辨率更多的压缩或拉伸,那么获得可接受的定位结果几乎是不可能的。 另一个考虑因素是热膨胀和收缩。 考虑一个GS执行器连接到正在执行精密磨削过程的刀具上。 假设工具是钢的,长12英寸,温度升高5度将导致工具膨胀0.0006英寸。 如果系统被编程为进行0.0002英寸的移动,则这种扩展可能会导致严重的定位问题。 这同样适用于执行器本身的组件。 执行器杆的温度可以从冷启动到运行温度变化。 在非常精确的定位应用中,可能需要考虑这种变化。
