Multinational polymer manufacturerigushas launched a new slewing ring that can be used to build lightweight, load-bearing systems which facilitate movement in a range of industrial equipment.
While the firm’s ‘PRT-04’ bearing is 60% lighter and offers 50% of the size of its PRT-01 predecessor, it’s still ultra-resilient, and capable of transmitting axial and radial forces as well as tilting moments within machine-moving applications. Though the component comes injection molded as standard, igus also offers to 3D print the product, as a means of customizing it for clients with use case-specific needs.
“Aluminum with plastic offers two decisive design advantages: it’s lightweight yet stable,” explains Fabian Wieking, PRT Slewing Ring Bearing Product Manager at igus. “Thus, despite its small size, the PRT-04 can hold its own against comparable products on the market and accommodate high loads (up to 3,500N) in the axial direction, even though it is much more compact.”
igus’ broad industrial offering
Igus总部位于德国科隆，但在35个国家和约4,900名员工中运营，是聚合物生产世界中的主要参与者。目前，该公司利用其自润滑的高性能塑料线创建从高度柔韧的电缆到iglide rangeof plain bearings and bushings, which now includes the PRT-04.
在过去的几年中，Igus通过创建内部初创企业进行了扩展，其中许多都是基于高级技术的，例如其用于精益机器人技术的RBTX平台及其3D打印服务。通过后者，该公司提供了生产原型和小批次的零件，以寻求利用其低摩擦益处iglide 3D打印材料， 哪个are marketed as capable of lasting up to 50 times longer than normal.
In the past, the service has been used to3D print self-lubricating linear axes来自Igus专有的Iglidur I3材料。其他选择利用该公司产品的人还包括电动汽车（EV）制造商Easelink， 哪个结合3 d印刷齿轮进入矩阵EV charging system早在2018年。
什么是起飞戒指和“ PRT-04？”
For those unfamiliar, a slewing ring is essentially a part designed to enable rotational motion between others in a system, whether that be in the process of moving a drill, crane or industrial packaging unit. The bearing is mainly composed of two concentric rings, with the outer element flat against a motionless surface, and the inner one affixed to a turning object, allowing it to rotate as needed.
According to igus, however, installing the drives and systems needed to enable motion in tight spaces is a “challenge companies face in many areas,” especially as requirements around machine components are “becoming increasingly stringent.”
为了满足对节省空间轴承解决方案的需求，该公司启动了PRT-04。像所有Igus轴承一样，PRT-04是自润滑的，对灰尘，灰尘和水分不敏感，但外径为60mm，它的安装尺寸也最小。
In terms of layout, the product itself features three aluminum rings, as well as a newly-developed sliding element made from the firm’s iglide J polymer. The plastic is said to work exceptionally well with aluminum, ensuring good coefficients of wear, while furthering its moisture and chemical resistance credentials.
实际上，即使在紧密的空间中，PRT-04也有望允许光滑的旋转和旋转动作，而Igus吹捧该产品的汽车和“移动头”应用，例如在火车和飞机上看到的旋转桌子中的旋转空间。尽管该公司对通过3D打印来调整零件的潜力的噪音较小，但可根据要求提供报价，这是可能的。
