Embodiment 1

[0025] see figure 1 , figure 2 with image 3 , this overall circular internal circulation reverser includes a cylindrical reverser body 1 and an S-shaped circulation channel 2; the S-shaped circulation channel 2 is integrally formed by the cylindrical reverser body 1 being recessed inward, and the The connection between the S-shaped circulation channel 2 and the upper surface of the cylindrical reverser body 1 is the connecting line 3 of the two raceways of the nut, and the two ends of the S-shaped circulation channel 2 are the nut circulation ports 4 that match the interface of the nut raceway. ; Inside the S-shaped circulation channel 2 is an S-shaped ball-returning space trajectory 5, and the mathematical model of the space-returning bead trajectory 5 is a quintic parabola. see figure 2 , the cross section of the S-shaped circulation channel 2 in the direction perpendicular to the bead returning space trajectory 5 is a single arc cross section, forming a single arc typ...

Abstract

The invention discloses an entire circular type internal recycling reverser which comprises a cylindrical reverser body and an S-shaped recycling channel. The S-shaped recycling channel is integrated by that the cylindrical reverser body is de-bossed inward. A connecting line is a joint between the S-shaped recycling channel and an upper surface of the cylindrical reverser body, wherein the connecting line is located at two end rolling rails of a nut. Nut recycling mouths which are anastomotic with connecting mouth portion of the nut rolling rails are the two ends of the S-shaped recycling channel. The S-shaped recycling channel is an S-shaped revolving bead space trajectory. The mathematical model of the S-shaped recycling channel is a quintic parabola. Engineering plastics of reinforced fibers can be used by the cylindrical reverser body, and the cylindrical reverser body is produced by an injection moulding craft. The upper portion of the cylindrical reverser extends out to form two assistant locating outer arc portions to increase stability of the reverser. The entire circular type internal recycling reverser is good in recycling trajectory smoothness, high in transmission property, high in production efficiency, low in cost and long in service life.

Description

[0001] technical field [0002] The invention relates to a key transmission part of a ball screw pair matched with a numerical control machine tool, an ordinary machine tool and a general equipment, in particular to an integral circular inner circulation reverser. [0003] Background technique [0004] The shape and structure of the retroverter has a round shape, and the retroverter hole on the ball nut must also be processed into a round shape, which is less manufacturable than the round retroverter hole, and the production efficiency is low. The cost is high and the quality is difficult to control. There are also two semi-circular types, which are formed into a circular shape by bonding, but the requirements for the adhesive are high, and the cost of one more process of bonding will increase, and the reliability is poor due to the large impact during the movement or the bonding quality is not good enough. There is also a steel reverser. The X, Y, and Z space coordinates ...
