Five things I should know about dryspin® lead screw technology: Importance of lead screw technology, details about the product range of dryspin® lead screw drives, difference in thread types, individual machining and configuration, and the lubrication of lead screw drives.
Lead screw drives are used in many machines in a wide variety of industries. Thus, the demands placed on a lead screw drive also differ: from high and low loads to high and low speeds to large temperature spans or even permanent temperatures around 200°C. Of course, the screw drives used should also perform flawlessly here.
In general, efficiency indicates how high the effectiveness of a device is when conversion losses are taken into account. The efficiency describes the relation between the delivered power (effective output) and the supplied power or loss and expenditure. In the calculation, the efficiency is abbreviated with a small eta (η). The result of the efficiency depends on what is considered a benefit or loss and what is considered an expenditure.
It is no secret that igus® is an advocate of non-lubrication of bearings. Simply put, lubrication is not required for igus® products. But that doesn’t stop customers from asking the recurring question: “Can I use WD-40 or another lubricant to grease my bearing?”
The dryspin lead screw technology was developed and patented in 2016 by the drylin lead screw technology development team. Particular emphasis was placed on increasing service life and improving efficiency. The dryspin product portfolio includes high-helix lead screws made of stainless steel or aluminium and the matching lead screw nuts made of igus high-performance polymers.
