摘 要

本次设计是进行一个直径是80MM长120MM的圆柱台阶轴进行设计，这个轴上有圆弧、工艺退刀槽、螺纹退刀槽、螺纹及球面构成，材料为45号钢。轴，支承转动零件并与之一起回转以传递运动、扭矩或弯矩的机械零件。一般为金属圆杆状，各段可以有不同的直径。机器中作回转运动的零件就装在轴上。根据轴线形状的不同，轴可以分为曲轴和直轴两类。根据轴的承载情况，又可分为：①转轴，工作时既承受弯矩又承受扭矩，是机械中最常见的轴，如各种减速器中的轴等。②心轴，用来支承转动零件只承受弯矩而不传递扭矩，有些心轴转动，如铁路车辆的轴等，有些心轴则不转动，如支承滑轮的轴等。③传动轴，主要用来传递扭矩而不承受弯矩，如起重机移动机构中的长光轴、汽车的驱动轴等。轴的材料主要采用碳素钢或合金钢，也可采用球墨铸铁或合金铸铁。轴的工作能力一般取决于强度和刚度。

Answer 1

This design is a diameter is the 120MM 80MM long cylindrical steps axis to carry on the design, the shaft has arc, craft recede cutter groove, thread recede cutter groove, thread and spherical form, material for 45 steel. Axis, supporting rotating parts and with the rotary motion, together with the transfer torque or bending moment of mechanical parts. General for round metal rods, paragraphs may have different diameter. Machine parts of rotary motion is installed in shaft. According to the different shape, shaft axis can be divided into two types of crankshaft and direct axis. According to the shaft bearing condition, can divide again: 1. At work, both rotor under bending moment and inherit torque, is the most common shaft in machinery, such as various reducer of bearing etc. (2) used to support, mandrels rotating parts only under bending moment and not transfer torque, some heart axis rotation, such as railway vehicle shaft etc, some mandrels are not rotating, such as supporting pulley shaft, etc. 3 main shaft, used to pass the torque and not under bending moment, such as crane mobile mechanism of long axis, the car's drive shaft, etc. Shaft materials mainly using carbon steel or alloy steel, also can use ductile iron or alloy cast iron. Axis of work ability general depends on intensity and rigidity自己参考下吧......

Answer 2

This design is carries on a diameter is the 80MM long 120MM column stair axis carries on the design, on this axis has the circular arc, the craft tool escape, the thread tool escape, the thread and the spherical surface constitution, the material is 45 steel.The axis, the supporting rotation components and rotates together with it transmits the movement, the torque or the bending moment machine parts.Generally for metal circle rod-shaped, each section may have the different diameter.In the machine makes the gyroscopic motion the components on the attire on the axis.According to the spool thread shape difference, the axis may divide into the crank and the straight axle two kinds.According to axis load bearing situation, also may divide into:①Revolution axis, when work both the withstanding bending moment and the withstanding torque, is in the machinery the most common axis, like in each kind of reduction gear axis and so on.②But the spindle, uses for the supporting rotation components only to withstand the bending moment not to transmit the torque, some spindle rotation, like the railroad car axis and so on, some spindles do not rotate, like supporting pulley axis and so on.③But the drive shaft, mainly uses for to transmit the torque not to withstand the bending moment, like in hoist crane shifting mechanism long optical axis, automobile drive shaft and so on.The axis material mainly uses the carbon steel or the alloy steel, also may use the modular cast iron or the cast alloy iron.Axis working ability is decided generally by the intensity and the rigidity.
