Ball screw with a dustproof member
A ball screw with a dustproof member includes: a screw, a nut and the dustproof member. The dustproof member is inserted along the axis into the annular receiving groove and sleeved onto the screw, and includes an annular first dustproof portion and an arc-shaped second dustproof portion. The annular first dustproof portion includes a dustproof hole for insertion of the screw, the dustproof hole has a dustproof inner surface defining an clearance relative to the circumferential surface of the screw, the arc-shaped second dustproof portion protrudes from the dustproof inner surface, and includes an arc-shaped dustproof section contacting the outer helical groove. Such arrangements provide a dustproof effect and prevent overstress on the screw, consequently decreasing friction resistance, thus making the assembly easier and reducing the required starting torque.
