造上比車六困難 易轉向路徑通常設置於滑塊端的端蓋中,製 岡丨J開,業L夕H 0 ^ 夕是在端蓋内直接鑽削開設出配合滾珠外型 M331058 的轉向路徑,但是這種製造方式不但加工手續相當麻煩,而且轉 向路徑也無法擁有與滾珠匹配的完整圓弧路徑,往往會導致滾珠 運轉不順暢且產生過大噪音。後來,為了簡化加工手續與形成完 整圓弧路徑供滾珠通過,業界就利用將端蓋分開射出成型的方式 •分別形成一半的轉向路徑,再組合成與滾珠匹配的完整圓弧路 • •徑。但是,這種分離型之端蓋對組件間的加工精密度要求相當高, 使加工製造上的成本因此提高。另外,當線性滾珠滑執組件實際 # 運作日守,一但端盍元件之間公差稍微過大就很容易造成端蓋相對 於滑塊產生震動,使滾珠無法麵地稱,並導致滾珠運轉磨耗 過大及發出噪音,進而影響到線性滾珠滑軌組件整體的運作效炉 及壽命。 【新型内容】 決先前技術所存在的問題。 先前技術巾分離式端蓋很糾受顺件公錢影響,使線性 滾珠滑軌組件運射端蓋會相對於滑塊產生異麵震動。馨於以 上的問題,本新型的主要目的在練供—種滾珠料端蓋,以解 一種滾珠導引端蓋,係應用It is more difficult to turn than the car six. The easy-turning path is usually set in the end cover of the slider end. The 丨 丨 J is opened, and the L H H 0 ^ 夕 is directly drilled in the end cover to open the steering path with the ball shape M331058. However, this manufacturing method is not only cumbersome in processing, but also the steering path cannot have a complete circular path matching the balls, which often causes the balls to run unsmoothly and generates excessive noise. Later, in order to simplify the processing procedures and form a complete circular path for the balls to pass, the industry uses the method of separately splitting the end caps. • Forming half of the steering paths separately and combining them into a complete circular path matching the balls. However, such a separate type of end cap requires a relatively high degree of processing precision between components, thereby increasing the cost of manufacturing. In addition, when the linear ball slide assembly is actually operated, once the tolerance between the end members is too large, it is easy to cause the end cover to vibrate relative to the slider, so that the balls cannot be surfaced and the ball running wear is too large. And the noise, which affects the overall operating efficiency and life of the linear ball bearing assembly. [New content] The problems existing in previous technologies. The prior art tissue-separated end caps are subject to the influence of the money, so that the linear ball-slide assembly transport end caps will produce a different surface vibration relative to the slider. In addition to the above problems, the main purpose of this new type is to provide a kind of ball end cap to solve a ball guiding end cover.
