Abstract
A rolling ball separator structure of a linear drive member includes multiple separators mounted between the multiple rolling balls and each having a body and an outer ring structure. Thus, the body may be deformed elastically, thereby preventing the multiple separators from interfering with the return face of the rolling path during the returning process of the rolling balls, and thereby absorbing the gap variation of the uneven force during the returning process of the rolling balls, and the outer ring structure may maintain the relative position of the rolling balls, so that the rolling balls will not collide directly during the returning process.
Claims6
A rolling ball separator structure of a linear drive member, comprising multiple rolling balls, and multiple separators mounted between the multiple rolling balls, each of the multiple separators including a substantially cylindrical body, the body having two sides each formed with a spherical concave structure for receiving the rolling balls at the two sides, wherein:
- the body of each of the multiple separators is formed by a high molecular material, the body has an outer periphery formed with a protruding outer ring structure, the outer ring structure has an outer diameter smaller than the diameter of each of the rolling balls, the body may be deformed elastically, thereby preventing the multiple separators from interfering with the return face of the rolling path during the returning process of the rolling balls, and thereby absorbing the gap variation of the uneven force during the returning process of the rolling balls, and the outer ring structure may maintain the relative position of the rolling balls, so that the rolling balls will not collide directly during the returning process.
