Q:At the time of mechanical design.
Agree upstairsYou write that part of your code ah, is their own parts produced by the company to write the parts of the drawing number, is the procurement of non-standard parts, the supplier to write the parts number.
Q:In the design of large machinery, it is to design the parts first, the assembly drawings as well
First of all, the transmission mechanism must be defined first, and then the strength of the transmission system must be calculated, and then the actual size, gear modulus and so onThen draw parts, assemble, assemble problems, and then change parts
Q:Are there any standards or specifications for the design of parts list in mechanical design?
Each company's specifications are not the same, but the general processing parts must have part name, parts drawing number, quantity, material / heat treatment methods (surface treatment methods), remarks, etc.. If purchased, it includes name, model, brand, requirement, remark and so on
Q:What are the basic requirements for the design of mechanical parts?
2. stiffnessThe elastic deformation of a component at work does not exceed the allowable limit. This is called the stiffness requirement. Obviously, only when the elastic deformation is too large to affect the working performance of the machine, it is necessary to meet this requirement. For this kind of parts, besides the strength calculation, the stiffness calculation must be done.
Q:In the mechanical design process, those areas should be designed to fillet. When will it be designed to chamfer? 10
Generally more chamfering, mainly to reduce stress concentration, easy assembly, easy to match the relative movement of parts. Most are inverted x 45 degrees, and in some places, if you want to pass O ring and some seals, it can be inverted to * 20 degrees /30 degrees angle. The fillet is much less Oh, you have to consider is mainly matched with the corresponding, both in the process of relative motion, if you feel there are steps can cause some problems such as stuck, with a smooth transition, it is better to fillet!In fact, the chamfering or rounding is mainly needed!
Q:What is the principle of selecting materials for machine parts in mechanical design?
If you pay attention, you will find that the country with the largest amount of steel, steel, steel and other materials is a low cost Q235 material, followed by Q345 and other materials, only in the shaft parts of important requirements, has high hardness and comprehensive strength, it needs conditioning, with 45 steel quenched and tempered steel or 40Cr like the.
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:How to design the common mechanical parts with CATIA, and how to solve the problem when the units are inconsistent?
When you build parameters, type select length, and enter units with values, such as "100mm"
Q:I would like to open a small mechanical design company (specializing in the design of mechanical parts, etc.) can you make money?
I really heard about this kind of company. Key: business promotion, design experience, additional experience.If you can get enough money, if you open the advertising skills and experience in mechanical design, powerful enough if you can tell the customer to design the end where I can get a good and where can I find a cheap and can ensure the processing precision and efficiency of the manufacturers, do it.On the contrary, think twice!
Q:How to judge parts in mechanical design and how to judge components?
parts, but to "the pedals and sprocket" together, and form component. Several components constitute a chain drive mechanism. Similarly, key parts.
