1/10 08 年 机械设计 期末复习指导一、填空题1塑性材料在静载荷作用下产生的失效形式为塑性变形；脆性材料在静载荷作用下产生的失效形式为脆性破坏；不论何种金属材料在变载荷作用下产生的失效形式为疲劳强度失效。2V 带轮传动中，当传动比i1 时，V 带可能产生的瞬时最大应力发生在带的紧边开始绕上小 大或小）带轮处。3齿轮传动的设计准则通常按保证接触疲劳强度及保证弯曲疲劳强度两准则进行设计计算。4蜗杆传动最易发生胶合和磨损两种失效形式。5轴传动中，既承受弯矩又承受扭矩的轴称为转轴。只承受弯矩而不承受扭矩的轴称为心轴。6在机器运转中，若两轴需要随时接合或分离，则可采用离合器。7圆柱螺旋弹簧的中径与弹簧丝直径之比称为弹簧旋绕比。8按材料和制造方法，常用机架分为铸造机架和焊接机架两类。9对于铰制孔用螺栓，设计时应按剪切强度和挤压强度进行计算。10开式齿轮传动的主要失效形式是齿面磨损和轮齿折断。11受静应力的45 钢零件，在强度计算时应取材料的屈服极限作极限应力。12在材料和包角确定后，带传动所能传递的有效拉力与初拉力成正比。13在螺纹联接中，当有一个被联接件太厚，并需要经常装拆时，宜选用螺钉联接方式。14在带传动设计中，应按计算功率和小带轮的转速来确定V 带的型号。15润滑油的粘度随油温的升高而降低升高或降低），粘度可以分为动力粘度、运动粘度、条件粘度。16圆柱形螺旋弹簧受载时，其簧丝截面主要受扭转切应力。17滚动轴承的正常失效形式是滚动体或内外圈滚道上的磨损、疲劳点蚀、塑性变形破坏。18轴传动时轴通常是在变应力条件下工作的，轴的截面尺寸发生突变处要产生应力集中现象，轴的疲劳破坏往往是在此处发生。19机械零件由于某些原因不能正常工作时，称为失效。20按 V 带设计的一般步骤，确定V 带根数后还应确定带的初拉力，并计算 V带对轴的压力Q 。21滚子链传动最主要的参数是节距。22链传动不宜用于高速传动，主要是由于链速不均匀，在传动中将引起动载荷。23按受力不同，弹簧可分为拉伸弹簧、压缩弹簧、扭转弹簧和弯曲弹簧等类型。24铸铁机架在铸造和机械加工时会引起较大的内应力为此应对其进行时效处理。25在机器运转中，若两轴需要随时接合或分离，则可采用离合器。26圆柱螺旋弹簧的中径与弹簧丝直径之比称为弹簧旋绕比。27 在机械传动中，常见的啮合传动有齿轮传动、蜗杆传动、链传动和螺旋传动等。28机械零件由于某些原因不能正常工作时，称为失效。29按 V 带设计的一般步骤，确定V 带根数后还应确定带的初拉力，并计算 V带对轴的压力。30滚子链传动最主要的参数是节距。31 在机 械 传动 中，常见的 啮合 传 动有 齿 轮传动、蜗杆 传 动、链传 动和螺旋 传 动等。32开式齿轮传动的主要失效形式是齿面磨损和轮齿折断。33受静应力的45 钢零件，在强度计算时应取材料的屈服极限作极限应力。34在材料和包角确定后，带传动所能传递的有效拉力与初拉力成正比。2/10 35对于链速vR2，材料弹性模量E1E2，则两者的最大接触应力C。AH1H2 BH1H2文档编码:CW1M8C10M9I1 HP4U1W6Z9W9
