Q: The inside diameter of my bearing is 12mm. Now I want to work on a round shaft so that it can fit into the bearing hole, and there is almost no pulsation in the radial direction. Then how should the shaft be designed? The axle diameter is just 12mm Or a little smaller than 12mm? How much smaller?Thank you for your answer, my bearings are NSK, the accuracy level is P4, diameter 12, outer diameter 32, then how should I design the shaft? And how to design the fixed seat (sleeve, bearing) of the bearing?: Axis of nominal diameter 10mm, size tolerance decides what you choose to look at the accuracy level of general level 6 or 7 grade precision, tolerance zone h, which is 12h6 or 12h7, the tolerance is not tight, you chose to use the occasion.

Q: is it the first overall drawing, or first out parts drawings, and then assembly?: Personal habits ~ ~ general circumstances, the first overall map, and then parts map ~!

Q: The strength criterion of mechanical parts design is briefly introduced: 3. heat resistance criteria, due to friction and other reasons, when the machine is running, the temperature of the machine parts and lubricants will generally rise. Excessive work temperature will lead to a decrease in lubrication effect, and will cause thermal deformation, hardness and strength degradation of the parts, even damage. In the high temperature, metal mechanical parts may be glued and stuck; plastic and other non-metallic mechanical parts may soften, or even melt, and in some cases will cause thermal stress. Heat resistance is generally not the temperature control criterion of mechanical parts exceeds the allowable value, in order to ensure the normal work of the parts, the expression is (3 - 18) in order to improve the temperature control performance, heat dissipation, when necessary, can use water or air cooling measures. 4. vibration stability criteria, when the frequency of excitation is equal to the natural frequency of the object, the amplitude of the object is the largest, the frequency of excitation is different from the natural frequency, and the amplitude of the object is smaller. When the frequency of excitation is close to the natural frequency of the object, the amplitude of the forced vibration is very large. This phenomenon is called resonance. Vibration stability refers to the quality of mechanical components avoiding resonance when the machine is running. In order to prolong the life of the machine, in order to avoid the damage of the shaft and the machine, the vibration stability of the axle is calculated, especially the axis of the high-speed machine.

Q: Are they usually steel 45? Under what circumstances do you need special treatment? Such as conditioning? Seek great God pointing! Be deeply grateful！: Cost considerations should be taken into account in mechanical design. If the material used in the design is too good, resulting in the overall cost is too high, it will make the loss of enterprises. The 45 steel is a slightly higher quality carbon structural steel, only in some major components or shaft parts only use 45 steel, and more use of lower strength Q235 and other carbon structural steel.

Q: Who knows what the design criteria for machine parts are, and how they are designed?: 5. life standards, in order to ensure that the machine in a certain life span of normal work, in the design of mechanical parts, it is necessary to request the life of mechanical parts. It should be explained that parts can be replaced during the life of the machine, that is, the life of some mechanical parts is shorter than the life of the machine. The life of mechanical parts is mainly affected by fatigue, wear and corrosion of materials. In order to avoid failure caused by parts fatigue, such as fatigue fracture, fatigue strength should be calculated according to the fatigue limit corresponding to the life of mechanical parts. That is to say, according to the requirements of life and the specific speed of parts, according to formula (3-6), the fatigue limit is calculated when the stress cycle number is N. Then the strength condition is calculated and the fatigue strength is calculated. When the fatigue strength is satisfied, the stress cycle times of the mechanical parts can be guaranteed before the damage. Wear is usually unavoidable. Under certain conditions, corrosion is inevitable, such as structural members of bridges, corrosion of buried steel pipelines, etc.. In the design, mainly to ensure the mechanical parts in life, not excessive wear and corrosion. The mechanism of wear is still fully mastered, and there are many factors affecting wear. Generally, the wear resistance of friction pairs is improved according to the tribological design principle. The main measures are as follows: reasonable selection of friction pairs, reasonable choice of lubricant and additives, and control of the working conditions of friction pairs, such as pressure, sliding speed and temperature rise. So far, there is no practical and effective method for calculating corrosion life

Q: What is the significance of using this "three changes" in mechanical design?: Standardization refers to the products (especially parts) the quality, specifications, performance, technical index structure and other aspects of the unified regulations and standards to perform. As the standard of our country has already formed a huge system, there are national standards, industry standards and so on. In order to in line with international standards, some standards in China the rapidly move closer to international standards. The standard code such as GB, JB, ISO and so on, they are representative of the national standard of People's Republic of China machinery industry standards, the international organization for standardization standards.

Q: Write the XX in the code for the detail column of the assembly drawingThe company's standard clerk says that the standard number or pattern code can only be used in the code bar. The part XX of my presentation is a part of the assembly drawing, which is a non-standard part. I wonder what standard to fill in Is it the material standard? But the material, Q235B, has been written in the material column.: A part of an assembly drawing. If it is a standard part, fill in the name of the part and the standard code. If it is a nonstandard part, fill in the part name and the code specified by the company.As you mentioned, it should be the standard staff who can only fill out the part code, which is the code number specified by your company. Drawing design, the non-standard parts using the company's parts code.

Q: How to write the machining process design of machine parts?: According to each process that the part needs to be processed, the processing technique is determined.

Q: The basic idea of mechanical parts design is briefly introduced: 1, according to the requirements and conditions, determine the type of parts2, determine the parts load, select materials, formulate parts work capacity, calculate the key size;

Q: What kind of software is used in the design of machine parts?: No, most, only the more, the most suitable for you is your most.If you usually design only 100 of the following parts, use SOLIDWORKIf it is under 1000, using proe is goodMore than 10000, then you use CATIAAs for UG, a little embarrassed, suspended in midair.
