Problems solved by technology

[0004] The ball rolling track of the existing ball nut and ball screw has a shallow track and the track opening width is larger than the track bottom width, so it can be processed by cutting and grinding, and it is relatively easy to manufacture
If the ball rolling track is a deep groove track, that is, the track depth is greater than the ball radius, and the track opening is smaller than the ball diameter, then ordinary cutting and grinding tools will be powerless

Embodiment Construction

[0036] figure 1 with figure 2 It is a schematic structural diagram of the present invention. The depth of the deep groove track 4 on the inner surface of the ball nut 2 is larger than the radius of the ball 3, but the track opening is smaller than the diameter of the ball 3, so the ball 3 is in the deep groove track 4, most of which are in the deep groove track 4 Inside, a small part is exposed outside the track, and the exposed part of the spherical surface coincides with the ball screw track 5 . figure 2 The normal section of this structure is shown in detail, the distance from the center surface of the ball 3a to the bottom surface 2b of the ball nut track (that is, the radius of the ball 3) is smaller than the distance from the inner circular surface 2a of the ball nut to the bottom surface 2b of the ball nut track ( That is, the depth of the ball nut track), most of the balls 3 are in the deep groove track 4. There is a gap between the outer circular surface 1a of th...

Abstract

The invention discloses a ball screw cap with a deep groove track and a manufacturing method thereof. After the ball screw cap is separated from a ball lead screw, balls on the inner circle surface of the ball screw cap is still limited in the deep groove track and are prevented from being scattered, so that the ball screw cap is convenient to be screwed out of and into the ball lead screw. The manufacturing method of the ball screw cap comprises the following steps of: drilling a hole on a blank with the conventional technology to form an inner circle surface; processing the inner circle surface with a turning method or a whirling method to form a spiral groove of which the depth is greater than the ball radius, the opening is a little smaller than the ball diameter, the normal section bottom side is a circular arc and the upper part is rectangular; introducing a spiral cutting tool into the spiral groove for cutting to form a deep groove track; and performing thermal treatment and surface treatment on the deep groove track.

Description

technical field [0001] The invention relates to a ball nut with a deep groove track and a manufacturing method thereof. After the ball nut is unscrewed and separated from the ball screw, the balls on the inner circular surface are still restricted in the deep groove track and will not scatter, which is convenient for the ball nut Unscrew and screw in the ball screw. Background technique [0002] The ball screw pair is a mechanical component that converts the rotational motion of the ball screw or ball nut into the axial linear motion of the ball nut or ball screw, including the ball screw with a spiral rolling track on the outer surface, including The round surface has a ball nut with a helical ball track, and a plurality of balls that can circulate and roll inside the ball track. [0003] In existing applications, no matter the ball rolling track on the outer surface of the ball screw or the ball rolling track on the inner surface of the ball nut, when the ball fits with i...
