Abstract
Description
本發明係為一種傳動元件，尤指一種外循環式滾珠螺桿。
The invention is a transmission element, in particular an outer circulation type ball screw.
按，滾珠螺桿的循環方式分為內循環式和外循環式等，前述內循環式或外循環式的滾珠螺桿的選用往往取決於滾珠螺桿的使用負荷條件。但是，無論是內循環式或外循環式滾珠螺桿皆運用迴流元件達成滾珠循環的目的。
如日本公開第２００６３４２９７６號專利中的第一圖所示，其在於螺帽上設有用以導引滾珠迴流的迴流元件，迴流元件係由一對具有腳部的迴流塊與迴流通管所組成。由於迴流塊和迴流管為一體式的設計，因此，在組裝滾珠螺桿時中的滾珠間隔環時，並不容易確認間隔環與滾珠間的空隙，造成組裝上的不便。
另有，如日本公開第２００７３０３５９０號專利中的第五圖所示，其於螺帽上設有用以導引滾珠迴流的迴流元件，且該迴流元件係分離為二。此種設計，因迴流元件接合面係直接遭受滾珠衝擊，所以回流元件容易從該接合面損壞，減少回流元件的使用壽命。
對於上述技術所需改善之處已有如第一圖~第二圖所示之滾珠螺桿迴流元件（９０），該迴流元件（９０）分為直管部（９１）和腳部（９２），其中該迴流元件（９０）之直管部（９１）分為上、下蓋（９１１）、（９１２）以便於確認間隔環與滾珠間的空隙，而該腳部（９２）為一體成型的方式形成，改善接合面係直接遭受滾珠衝擊的問題。不過，該直管部（９１）之上蓋（９１１）突出一對位部（９１３），並於該上、下蓋（９１１）、（９１２）組合時，對位部（９１３）卡掣於下蓋（９１２）內部，接著透過外蓋（１００）將迴流元件（９０）鎖固於螺帽上。如此一來，當外蓋（１００）板鎖固時，該上蓋（９１１）遠離螺帽的側邊受到外蓋（１００）側向壓力（如第六圖的箭頭所示）會脫離該下蓋（９１２），造成下蓋（９１２）無法支撐部份上蓋（９１１）導致上蓋（９１１）受力變形，進而影響滾珠循環。
According to the circulation mode of the ball screw, it is divided into an inner circulation type and an outer circulation type, and the selection of the inner circulation type or outer circulation type ball screw often depends on the use load condition of the ball screw. However, both the inner circulation type and the outer circulation type ball screw use the reflow element to achieve the purpose of the ball circulation.
As shown in the first figure of Japanese Patent Publication No. 2006342976, the nut is provided with a reflow element for guiding the reflow of the ball, and the reflow element is composed of a pair of recirculation blocks having a foot and a return pipe. Since the reflow block and the return pipe are of an integrated design, it is not easy to confirm the gap between the spacer ring and the ball when assembling the ball spacer in the case of assembling the ball screw, resulting in inconvenience in assembly.
Further, as shown in the fifth figure of Japanese Patent Publication No. 2007303590, a reflow member for guiding the reflow of the balls is provided on the nut, and the reflow member is separated into two. In this design, since the reflow element joint surface directly suffers from ball impact, the reflow element is easily damaged from the joint surface, reducing the service life of the reflow element.
For the improvement of the above technology, there is a ball screw reflow element (90) as shown in the first to second figures, and the reflow element (90) is divided into a straight pipe portion (91) and a leg portion (92), wherein The straight tube portion (91) of the reflow element (90) is divided into upper and lower covers (911) and (912) to confirm the gap between the spacer ring and the ball, and the leg portion (92) is formed integrally. To improve the joint surface directly suffers from the problem of ball impact. However, the upper cover (911) of the straight pipe portion (91) protrudes from the pair of seats (913), and when the upper and lower covers (911) and (912) are combined, the alignment portion (913) is stuck under Inside the cover (912), the reflow element (90) is then secured to the nut through the outer cover (100). In this way, when the outer cover (100) is locked, the side cover (911) is separated from the side of the nut by the lateral pressure of the outer cover (100) (as indicated by the arrow in the sixth figure), and the lower cover is removed. (912), causing the lower cover (912) to be unable to support a portion of the upper cover (911) causes the upper cover (911) to be deformed by force, thereby affecting the ball circulation.
