  1. In the course of working, , the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly

    與單向犁相比,其優點在於:耕地開、閉壟,地表平整,降低了耕后整地的能量消耗,減少了地頭的空行程,因而大大提高班次生產率。為了滿足犁體梭式作業的要求,我們採用了一隻小容積雙作用的液壓油缸;同時對犁壁曲面的狀採用了近似圓柱的對稱設計。但經過一段時間的田間試驗,我們發現:該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中較為嚴重;主犁梁和油缸缸體的連接部分(即油缸底座)突然發生了斷裂,造成整個犁體法正常工作。
  2. The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film

    試驗結果表明:所選原料的尺寸、狀及純度可滿足固體潤滑劑的性能要求;聚四氟乙烯樹脂熱分解溫度超過400 ,但在ptfe中加入機填料會使復合材料吸水率提高,熔融溫度及分解溫度降低,且伴有氧化分解反應;碳纖維表面含有c = o及c - o - c等極性基團,有利於提高其與其它組分的相容性,提高層間剪切強度;均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系,擬合曲線基本能表示各配方的摩擦系數發展趨勢;配方中不加銅粉或不加石墨,其摩擦系數均較高,說明銅粉和石墨應該配合使用;當銅粉15份、石墨60份時,銅粉30份、石墨30 - 40份時,銅粉60 、石墨15 - 30份時,摩擦系數均具有較低值;純聚四氟乙烯樹脂在空氣冷卻時結晶度最大,量也是三者中最大的;同時,固體潤滑劑試樣在空氣冷卻時的量也是三者中最大的:不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副,在金屬表面均可成潤滑轉移膜,從而減少金屬摩擦副表面間的直接接觸,大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。
  3. The wearing resistance, microstructure, worn surface morphology and hardness change in wearing end - face and non - wearing end - face of cr - mn - cu alloy white cast iron were tested and analyzed

    摘要對鉻錳銅合金白口鑄鐵的耐性、端面及端面的微觀組織、貌及硬度進行了試驗和分析。
  4. Because of the feature of short life, moral wear - out and physical wear can be displayed quickly. the decision of maintenance and replacement has certain universal significance

    因為壽命周期短的特點,無形磨損和陳舊落伍問題會突現出來,所以本文的維修與更新決策有一定的普遍意義。
  5. Then the physical wear of personal computers can be compensated. secondly, when personal computers rum up moral wear - up, both upgrading and changing can solve this problem. which mode on earth can be adopted

  6. The proposed wear mechanisms of the materials without oil lubrication were the followings : the wear mechanisms of the ferroalloy are adhesive wear, abrasive wear, and some oxidation wear. the wear mechanisms of the composites are abrasive wear and the brittle peeling off. the abrasive wear and the brittle peeling off incr eased with the increase of sic particles content in the composites

    潤滑條件下,通過對貌的觀察,認為鐵基合金的機理主要是粘著,同時伴隨有一定程度的氧化;加入sic後主要是和脆性剝落,且sic越多材料的脆性剝落越嚴重。
