- 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?
- The specific reference to the mechanical design manual, there are examples to follow the steps above to do down, the calculation process has a 3,4 page, but also to calculate what the shaft strength, but not so easy to design, and your condition is not good, you should also give the work work strength of the shaft, and is expected to life and work in different intensity of life is not the same, so the design steps are not the same, you still buy this book to see it, this question is not clear.
- Q: In the design of large machinery, it is to design the parts first, the assembly drawings as well
- In the design of large machinery, it is to design the parts first, the assembly drawings as well
- 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: In the design of machine parts, how to choose the matching of bearings, what should be paid attention to when assembling?
- According to the performance requirements of parts, the accuracy grade of bearings and the matching accuracy of shafts and bearings are determined
- Q: And parts, components, institutions, the relationship between the threeIs the key a part?
- The part is a processing unit, is processed. Parts of component is the moving unit. Mechanism is to achieve complete movement of the unit. For example, bicycle chain is composed of many parts (chain, pin, etc.) is a chain sprocket component; parts, but to "the pedals and sprocket" together, and form component. Several components constitute a chain drive mechanism. Similarly, key parts.
- Q: How does the Auto CAD menu bar do not have the "mechanical parts design" command?
- 1, will download the atuoCAD mechanical design package unpacked to atuoCAD20** installation directory.2, access to atuoCAD - tools - Options - files - the path to adding atuoCAD mechanical design packages to support file search paths.3, enter the "custom" tool - - - "transmission interface, select the main CUI file in the box at the top of the left column, the choice of transmission interface (acad.cui); the box open at the top of the mechanical design package transmission interface on the right side of the column selection, selection of mechanical design: inside the package.Cui file, start menu items you can see, the design of mechanical parts in the following.4. Expand the menu items in the left and right columns, and drag the design of the machine parts in the right column to the end of the menu item in the left column, and click the Save button at the top of the left column. Click apply to confirm!5, in the command line "menu", select "Support" under the acad.CUI file open, you will see the machine parts design menu hung up!
- Q: Fixture assembly drawings, detailed parts drawings, design instructions, machining processes, integrated cards, and process cards will be added
- Learn tyrants thing in the community are not practical, in the factory to consider a lot of factors, not necessarily good! Encouraging a pa! Or go to the society to study well!
- Q: What are the main principles of mechanical principles and mechanical parts design?
- Factors to consider when designing mechanical parts:1. the function of the parts, the parts in the equipment, and its uses. Is the part shaft or instrument housing or support seat?2. the load of the parts, according to the load or according to the strength requirements, determine the brand of material.3. heat treatment conditions, heat treatment and no heat treatment conditions, the election of different materials;
- Q: Before listening to the teacher mentioned that, when the design of components, we should take into account the actual processing capacity of the factory, and some look very simple things, the factory is unable to process! I want to know what the reason is!!!
- There should be a lot of things. For example, the processing capacity of the equipment is only 1000mm, and the things you design have 1100mm, so the existing equipment can not be processed. For example, the surface roughness you require is Ra0.2, and the machining accuracy of your equipment can only be Ra0.8. That's more than the processing capacity of the equipment. And some things are processing problems, for example, you design things outside the small hole, there is a big hole inside, your device does not have this function.Think of these kinds of things for the time being.
- Q: Mechanical design of various parts of the hardness value of how to determine?.
- Give your reference value, heat treatment is most hard, probably 65HRC, this is the limitAnd 45 steel without heat treatment, only about 10When you design, the hardness does not require a material can be set, there are hardness requirements, then the technical requirements of hardness
