摘要: 
滑動機構是常見的運動機構之一,亦被廣泛地應用在重負荷的滑動硬軌,硬軌表面會進一步經手工鏟花在其軌道面形成多個能含油的油袋,以降低滑動摩擦力,然而手動鏟花的品質會因人而異,對於鏟花幾何紋理的效果,亟需有系統的分析與探討。本研究以CNC加工的方式在滑塊上加工具斜楔的不同油袋型貌,以模擬手工鏟花的功能,藉此有系統地分析不同紋理與使用條件下對其摩擦特性的影響。
本研究搭配兩種實驗設計方法,首先使用田口實驗規劃法設計表面紋理參數以降低實驗的數量,其次對於使用條件,包括滑塊負荷、使用油品(不同潤滑油)以及滑動速度進行全因子實驗,藉以篩選出較佳之紋理與使用條件。研究探討之紋理參數包括(A)接觸面凸點分佈之比例POP、(B)單位接觸面之凸點數PPI、(C)紋理與運動方向夾角以及(D)油袋深度等四個控制因子,藉由L9(34)直交表設計9塊具不同紋理之摩擦塊進行實驗。而使用條件之參數則規劃6kg、12kg與16kg不同負荷;32號、68號與150號三種不同潤滑油以及500mm/min、1500mm/min、2500mm/min與3500mm/min四種滑動速度進行全實驗。
研究結果歸納如下:(1)滑動開始時,摩擦力甚大,隨後則逐漸下降並趨於穩定,負載小與運動速度大之滑塊摩擦力變化較大。(2) 黏滯性高之潤滑油造成之摩擦較大,但由實驗量得之摩擦係數觀之,重負荷與低速運動時摩擦係數較小。(3) 由田口實驗分析可得36種使用條件下較佳之紋理,經整理篩選四種較佳的紋理組合依序為(i)A3B1C2D2、(ii)A2B1C2D1、(iii)A1B3C2D1以及(iv)A1B1C2D3,該四種紋理組合之滑塊經實驗驗證,在相同使用條件下,其摩擦係數較原滑塊降低比率分別為(i) 12.6%至26.1%,(ii) 22.3%至35.8%,(iii) 27.9%至41.8%,以及 (vi) 46.1%至62.8%,顯示本研究所規劃設計之實驗的有效性。本研究結果顯示斜楔油袋型紋理之PPI、POP、深度與運動方向以及使用條件都會影響其摩擦力,研究之成果可作為進一步搭配使用條件之摩擦面表面紋理設計之依據。

Sliding function is one of the most popular motion functions, which be used on heavy loading sliding guideway generally. Sliding function forms many oil-bag on guideway surface by scrapping manually to reduce friction while sliding. However, manual scrapping quality may vary due to different operators. Therefore, we extremely need to analysis and explore different results of scrapping geometric texture systematically. By simulating manual scrapping, this research using CNC to process different wedged oil-bags on slider to analysis the effect on friction by different textures and conditions.
The research including two experiments. First, we use Taguchi Methods to design texture parameter on surface to reduce experiment quantity. Second, on parameters, including slider loading, different lubricating oil, and sliding speed, we do total factor experiment to filter better texture and condition. By L9(34) chart, we designed 9 pieces friction areas with different textures. The texture parameters we researched contain four control factors: (A). POP of contact points (B). PPI of contact points (C). Motion direction (D). Depth of Oil-Bag. Concerned with the parameter on experiment, we used three different loadings, 6kg, 12kg, and 16kg. Additionally, 3 different lubricating oils, No.32, No.68, and No.150. Finally, four different sliding speed, 500mm/min、1500mm/min、2500mm/min and 3500mm/min.
Research results: (1) Friction was so high while sliding at beginning, but lower gradually and became stable finally. Slider friction has large variation with light loading and high speeding. (2) High sticky lubricating oil makes high friction. However, from experiment we got lower friction by heavy loading and slow motion. (3) By Taguchi Methods, we got better texture charts by using 36 kinds of conditions. These four
texture combinations are:(i)A3B1C2D2,(ii)A2B1C2D1,(iii)A1B3C2D1 ,and
(iv)A1B1C2D3. The experiment showed the reduce rate of friction of these four texture combinations change from (i)12.6% to 26.1%, (ii)22.3% to 35.8%, (iii)27.9% to 41.8%, and (iv)46.1% to 62.8%. The statistic proved the effective of planned experiment.
This research shows either PPI, POP, depth, motion direction, or other conditions of texture on Wedged oil-bag would makes different friction. Furthermore, it also can be the important reference of designing surface texture friction.
