Abstract
A ball screw assembly, wherein the circulate component is positioned in the nut by inserting a protrusion in a notch, so that the circulate component is positioned easily, and the problem of assembly difficulty is solved. The method of fixing the circulate components in the nut is that: the circulate component is formed with an axial hole and the radial hole that are connected to each other, the axial hole of the circulate component is aligned to the axial locking hole of the nut, and then liquid resin is injected into the axial hole of the circulate components, and the liquid resin will form a locking members after curing, thus fixing the circulate component in the nut. Due to the formation of the locking member is determined by the diameter of the hole to be machined, the configuration of locking member will be varied in response to the diameter of the hole to be machined. Whatever the diameter of the hole to be machined changes or not, it will not affect the interchangeability of the locking member. Therefore, the production cost is saved since it doesn't need to prepare different sized locking members.
