What is the backlash error?
Advertisements
उत्तर
Due to constant use, there is space for the play of screw gauge but gradually this space increases with the use or wear and tear so that when the screw is moved by rotating it in some direction, it slips in the nut and does not cover any linear distance for some rotation of the screw head. The error due to this is known as backlash error.
