1. A locking system comprising:
a first nut arranged on a shaft and adapted to contact with an upper side of an inner ring of the bearing;
a second nut arranged on the shaft and separated from the first nut at a predetermined distance; and
at least one locking screw adapted to be screwed at least through a first through hole of the second nut and a second through hole of the first nut while the first through hole and the second through hole are aligned with each other, to thereby apply a force to a bearing on the shaft along an axial direction of the shaft.
