However, if the problem is not solved, the nut_type ball screw cannot be achieved. If the load capacity is serious, the service life will be shortened. In view of the above, the present inventors have developed the present invention by using various years of professional experience and experience, and have been developing and researching to improve the above-mentioned technology. [Summary of the Invention] The present invention is based on the above-described conventional nut rotating ball screw. The problem of the present invention is that the inventor of the present invention has been able to withstand the axial load between the rods between the outer ring of the bearing and the nut of the invention after the research of New Zealand. The axial load capacity of the party is matched with the nut and the screw. The purpose of the present invention is to provide a nut-rotating ball screw-screw having a first rolling groove; a nut cap is sleeved on the screw, and an inner edge thereof is opposite to the first - "The first groove of the moving groove - the rolling groove, the outer edge is provided with the second rolling groove;" The ring is set on the nut, and the inner edge is opposite to the second half - the second of the rolling groove Rolling groove; the birch two-dry rolling element's skirt is set in the first rolling groove and the first rolling gs, so that the screw and the nut can be relatively spirally moved; the reflow element is installed in the tethered material - The infinitely recirculating return of the rolling member, the cow of the groove, is installed on the second rolling groove and the second rolling member, and the outer ring of the bearing and the bearing is relatively rotatable; the surface of the second rolling member is The second rolling state, by the line contact surface is the wire connection technology. Because of the use of the ball, the ability is better than the point contact (the 'inferior ball and the rolling surface is point contact state) between the special outer ring and the nut The ability to withstand the axial force and the ability of the nut to bear the sleeve to match the load, Enhance their life. The following is a description of the implementation features of the present invention. The following describes the advantages and practical ways of the present invention: 1324230 2: Γ-turn ball screw, the second rolling between the bearing outer ring and the nut The piece is in line contact state, so the ability to withstand the axial load is better than the conventional point contact state. Therefore, it is possible to withstand the axial load between the screw and the nut without increasing the outer diameter of the second rolling member. The ability to match each other, so there will be no increase in the outer diameter of the outer ring of the bearing. In order to further understand the features and technical contents of the present invention, please refer to the following description of the embodiments of the present invention and the drawings, however, the implementation is for the lang and reference, and (4) for the use of the invention. 】: For the embodiment of the invention, please refer to the second and third figures. The present month is a nut-rotating ball screw, which comprises: _ screw #1 'with a first rolling groove 1 1 The first sleeve is disposed on the screw 1 and the inner edge thereof is opposite to the rolling groove 22; the outer edge of a rolling groove 21' is provided with a plurality of second first rolling grooves 2 1 opposite::: :::2==— The rolling element 5 is installed between the first rolling groove 1 i and the first portion, so that the screw 1 and the nut 2 can be relatively screwed 8 , and the reflow element 6 ′ is installed in the The nut 2 is provided thereon, and the passage 61 provides an infinite circulation of the first rolling member 5, the right first is the first; the swaying member 4 [the second rolling member uses the roller (as shown in the second figure) Or a roller cone (as shown in the third figure) is installed as a transmission medium between the second rolling groove 22 and the second rolling groove 31 to rotate the nut 2 and the bearing outer ring 3 relative to each other. Movement; the surface of the second rolling member 4 is in line contact with the surface of the second rolling groove 22 and the second rolling groove 3 i. The ability to bear the load by the line contact is greater than the point contact. The bead 'dead ball and the rolling (four) point contact state) 'the axial load capacity between the nut 2 and the bearing outer ring 3, and the axial load between the screw 1 and the nut 2 Ability to match each other' to improve their life.彳4 The ability of the invention to withstand the load by line contact is large = the characteristic of the contact 'the axial load between the outer ring of the bearing and the nut and the axial load between the nut and the screw The ability to achieve the ball screw pre-load capacity and improve their life. Therefore, it is undoubted that the "existing industry's availability" of Mingzhi has not been seen before, and has not been publicly used, except for the above. The fact that the work 1324230 is increased, the fact that it is more inexplicable _ sex and "progressive" ~ The law proposes the invention of the invention patent, I go to the rules, attack the real feelings. The disclosure of the above-mentioned embodiments is intended to be illustrative of the present invention and is not intended to limit the invention.
