Friction in a Ball Screw Assembly

 


Visitors: 285

Ball screws are types of linear actuators that are utilised in a range of fashions, most typically because they are linear actuators which typically work with low levels of friction. This phenomenon reduces the efficiency of a mechanism. Friction is defined as a resistance to movement, that may be experienced between a pair of objects in contact. Depending on the nature of the surfaces of these two bodies, the resistance to movement will be of a high level.

In general, the more smooth the surface, the less friction that will be detected when the objects are moved. Low friction mechanisms e. g. ball screws have high levels of efficiency.

This is a consequence of the Law of Conservation of Energy. This universal physical law states that one cannot create or obliterate energy, it can only be changed from one form to another. The point of this with regards to ball screws is that you can’t create or destroy energy. If a certain lump of energy has been transferred to the ball screw assembly, that is the total that will be utilised by the mechanism of the ball screw. However a substantial chunk of this energy can be dissipated, by being transferred to heat energy because of friction. It is for this reason that if there are low frictional effects in a ball screw assembly, the the greater its energy efficiency will be.

An additional benefit of small effects of friction in the interior of a ball screw assembly is a greater operating lifespan. In the case of two objects that are pushing against each other, a consequence of this will be erosion. The continuous scraping degrades the two bodies, slowly making them smaller.

As ball screws display only little bits of friction, especially when correctly lubricated, they are also longer lasting than other types of screws. An additional fact is that a lot of ball screws may be operated in reverse, precisely as a result of the low friction and free flowing motion inside the ball screw assembly. This means that there is little resistance to movement in either direction.
