The outstanding tribological properties of this cast polyamide are demonstrated by another trade fair exhibit: Lauramid® gear wheels. Lubricant-free operation, optimum sliding properties and outstanding noise and absorbability performance make Lauramid® gear wheels the ideal partner, particularly in plastic-steel combinations. As a result, the many applications it is used in run more economically. Gear wheels made from high performance plastic allow for even greater power transmission (higher torque) and therefore the ability to move more weight.
High torque and the dynamic acceleration that occurs as a result are just some of things required by tyre manufacturing plants, in which PA 12C Lauramid® works as a pinion shaft, or in a barley turning facility where 1,300 Nm of torque is required.
The cast polyamide even retains its form underwater: as a gear wheel in an underwater turntable it can withstand loads of 150 KN at 6 rpm - and that while maintaining complete form stability despite the damp environment.
Low maintenance and reliable performance, for example, are particularly important when the PA 12C Lauramid® is being used for components in machines that run 24/7. This applies e.g. to gear wheels in packaging or food industries. In cooperation with moulded metal hubs, low-cost comprehensive solutions are also possible with Lauramid® FS, designed for food contact. This could, for example, also be used in medical technology or food production. In these sensitive areas, the dry-running capabilities of Lauramid® become particularly important: for hygiene reasons, no external lubrication is permitted.
