A ball screw assembly is follows a simplistic design although they do have a number of small components. If everything is as it should be, the ball screw should function smoothly and easily, with the ball bearings running freely along the threads and through the recirculation system.
Unfortunately ball screw assemblies may be ruined by any small obstructions. If a situation develops that small pieces of dust or dirt get wedged along some of the pathways inside the ball screw nut, this can cause the ball bearings to operate less smoothly as is the case with Agricultural Machines. A key element of the efficiency levels of ball screw assemblies is the low levels of friction they generate. A blockage in the assembly can affect this however, increasing frictional effects and lowering efficiency.
Wiper systems are mostly comprised of little pieces that can sweep along the threads of the ball screw nut, effectively cleaning it of any particles. Most wipers will be made of either brush, elastomer or felt. There is of course a selection of wiper designs being used in ball screw assemblies at the moment. All of them have a one function, that is to collect any pieces of dirt that might be inside the ball screw assembly. The most typical material that is used for wipers is plastic, i.e. elastomer, and they are constructed in such a way as to generate friction. The friction that is generated by the wipers will attract any particle that is swept up by them. A range of wipers also features an extra felt wiper, that applies lubrication to the ball screw nut threads using either oil or grease. This system means that the plastic wipers sweep the threads, while the felt wipers grease them.
Wipers can increase the lifespan of, and will have the greatest effectiveness if added to a properly sealed ball screw.
