Lead screw drives are machine elements that convert rotary movement into linear motion. dryspin® lead screw drives are always based on self-lubricating plastic nuts, enabling long-lasting operation without external lubrication. dryspin® lead screw drive technology
is based on the principle of lubrication-free linear technology. The properties and geometries of the lead screw drives, which are tailored to the plastic nut and lead screw, along with the unique dryspin® technology guarantee an even longer service life and greater efficiency.
What was needed: A parcel station locker system that offers users maximum ease of maintenance
Requirements: Absolutely no lubrication or maintenance, quiet dry operation, mechanical resistance, simple implementation, low wear, ability to handle high loads
Products used: dryspin® lead screw, drylin® linear guide, iglidur® polymer plain bearings
Success for the customer: To offer users maximum ease of maintenance, the engineers use igus® polymer plain bearings in the electromagnetic guides. They allow dry, quiet, maintenance-free operation without external lubrication and are mechanically resistant. This also applies to the lead screws and linear guides used in the parcel locker opening mechanism.
What was needed: A delta robot capable of picking up fish and injecting them with vaccine
Requirements: Absolutely no lubrication or maintenance; resistance to corrosion, fresh water, salt water, cleaning chemicals, and abrasion; robustness
Success for the customer: Since the robot is used outdoors on fish farms in Norway, Scotland, and Iceland, all components must be resistant to fresh water, salt water, and cleaning chemicals. The company therefore uses robust, lubrication-free igus® polymer bearings, anodised shafts, and lead screw systems. The design engineers also manufactured a vaccine injector from a CNC block of high-performance polymer. It is resistant to abrasion and to the oil-based vaccines.
