It is usual for this to happen. I also learned that not all great ideas 16 . Failure(失败) is a 17 part of the inventing.As my father and I worked together, I began to 18 that my dad was quite an inventor himself. He was always 19 a better way to do an easy job.

深沟球轴承公差标准

深沟球轴承公差标准

深沟球轴承公差内径带的位置和大小与一般基准孔不同,(G与E)或(0与6)滚动轴承的内径是有特殊公差带位置的基准孔,各精度等级轴承内径的公差带从零线起向下布置,上偏差为零,下偏差为负值。

深沟球轴承公差外径带位置与基轴制类似,从零线起向下布置。

1、当轴承内径公差带与轴公差带构成配合时,在一般基孔制中原属过渡配合的公差代号将变为过赢配合,如k5、k6、m5、m6、n6等,但过赢量不大;当轴承内径公差代与h5、h6、g5、g6等构成配合时,不在是间隙而成为过赢配合。

2、轴承外径公差带由于公差值不同于一般基准轴,也是一种特殊公差带,大多情况下,外圈安装在外壳孔中是固定的,有些轴承部件结构要求又需要调整,其配合不宜太紧,常与H6、H7、J6、J7、Js6、Js7等配合。

3、选用与滚动轴承的精度有关:①与G(0)级轴承配合的轴,其公差等级一般为IT6,外壳孔为②与E(6)、D(5)级轴承配合,轴一般为IT5,外壳孔为IT6。

要看具体使用条件,如果对轴是旋转负荷,转速较高,负荷较大,则要求紧一些;如是静止负荷,则可松些;也要看安装方式,如果内外圈同时安装,为装配方便计,也应松些;一般情况下,轴一般标0~+0。

005 如果是不常拆的话,就是+0。

005~+0。

01的过盈配合就可以了,如果要常常的拆装就是过渡配合就可以了。

我们还要考虑到轴材料本身在转动时候的热胀,所以轴承越大的话,最好是-0。

005~0的间隙配合,最大也不要超过0。

01的间隙配合轴承一般是轴承与孔过渡或间隙,特殊用途用过盈,如果选择过盈的话轴承孔选N7,P7,轴分别选N6,P6,孔的公差提高一等级。

楼上的K7是过渡配合,也可以选的,在一般如果要求精度不高的情况下,可以使用轴承与孔过渡配合。

历年采购师真题M6统考试题说课讲解

历年采购师真题M6统考试题说课讲解M6历年试题判断1.在获取报价的过程中,邀请供应商的数量越多,意味着更激烈的竞争,因此会获取较低的报价,所以一般来说邀请供应商的数量是越多越好。

错M6P59。

2.采用所有权成本法作为评价报价的基础时,采购方不应考虑货币的时间价值。

错M6P38。

3.在采购过程中,企业希望与供应商所建立的关系类型影响获取与选择报价的方法。

对M6P5。

4.获取与选择报价流程的一般步骤,不论邀请供应商的数量是多还是少,这些步骤都会有所涉及。

对M6P7。

5.使用标准化的文件是公司在获取与选择报价过程中优化流程、增进与供应商交流、降低成本的一个重要方法。

对M6P876.在接受报价与签约阶段,对低价值和低风险的项目,供应商可能会口头同意接受报价,即使在这种情况下也要通过书面的形式加以证实。

对M6P837.企业采购供应战略影响获取和选择报价的方法,获取与选择报价的方法决定企业的采购供应战略。

对M6P88.针对瓶颈项目,在确定获取与选择报价的方法时,由于交易额少对供应商没有吸引力,因此应采用简单非正式的方法。

错M6P159.在获取与选择供应商报价的过程之前,针对采购项目的特定供应目标应该已经确定。

对m6p7-810.在采购过程中,企业希望与供应商所建立的关系类型并不影响获取与选择报价的方法。

错m5P811在选择供应商报价评估标准时,与其他因素相比,成本不是决定性考虑因素。

成本不能确定的情况应选用最低价格标准。

错M6P1512评估供应商的报价时,价值评估方法将是一个报价的非成本优势与它的关联成本进行对比,这个成本既可以是采购价格也可以是所有权总成本。

对M6P5413使用加权评分法对供应商的报价进行评估之前,应确保对供应商的选择是建立在对许多相关标准进行全面评价的基础之上。

对M6P4614 当采购成本或风险相当大并且公司只有有限的技术知识和供应市场条件及选择时,选择供应商的数量应该是少数几个。

对M6P1515.两段式招标方法适用于标准品的采购。

When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals usedifferent senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊猫)eats only one particular type of bamboo(竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶)will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet(多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.31. We can infer from the text that humans and animals _________.A. depend on one sense in choosing foodB. are not satisfied with their foodC. choose food in similar waysD. eat entirely different food32. Which of the following eats only one type of food?A. The white butterfly.B. The small bird.C. The bear.D. The fox.33. Certain animals change their choice of food when ___________.A. the season changesB. the food color changesC. they move to different placesD. they are attracted by different smells34. We can learn from the last paragraph that __________.A. food is chosen for a good reasonB. French and British food is goodC. some people have few choices of foodD. some people care little about healthy diet Ⅲ. 完形填空(共20小题,每小题1分,满分20分)In the United States there was an unusual tale telling of the daughter of a mechanic (技工).
