The proportion of hydraulic pumps and motor devices in the hydraulic system is very important. A good hydraulic system requires a good hydraulic pump and a good motor. Therefore, when configuring the hydraulic pump and the motor , We need our special attention.
Mechanical Engineering is a discipline that applies engineering, physics, engineering mathematics, materials science, and other natural sciences and theoretical foundations to design, analyze, manufacture, and maintain mechanical systems.
With the development of technology, there are more and more cutting methods, such as: laser cutting, water cutting, plasma cutting, wire cutting…What is the difference between them?
Today, people are increasingly demanding low-carbon environmental protection, aluminum alloy has become a substitute for many metals, its low density, high strength, easy processing and other advantages, more and more applications in automobiles, high-speed rail, aviation, ships The wider it is, the aluminum alloy will definitely make a greater contribution to human development.
Several common unfolding formulas for sheet metal.
The so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical surfaces. Due to the production technology limitations, counterfeit bearing products are not handled satisfactorily at these corners. We can easily Identify.
Why can’t the aircraft be welded? Decades of doubt finally understood!
Unless we consciously change our thinking and behavior, how to simplify complex things will be an eternal challenge. As Steve Jobs said: “Simple may be harder than complex: you have to work hard to make your thinking clear and keep it simple. But in the end it is still worth it, because once you do this, you can create miracles.”
Those who did not understand, those who could not speak, those who could not write, and those who could not paint, eliminated themselves.
When the bolt is broken, the easiest conclusion that people can draw is that the strength is not enough, so most of them adopt the method of increasing the strength level of the bolt diameter. This method can increase the pre-tightening force of the bolts, and the frictional force has also been increased. Of course, the anti-loosening effect can also be improved, but this method is actually a non-professional method, its investment is too large, and the benefits are too small.
Flange bolt pre-tightening force is the pre-tightening force in the direction of the axis of the bolt generated between the bolt and the connected part under the tightening torque during the bolt tightening process.
Bearing heat treatment is directly related to the subsequent processing quality, which ultimately affects the performance and life of the parts.
When the motor is running under load, the total internal loss is converted into heat energy to increase the temperature of the motor. The poor heat resistance in the motor is the insulating material. If the load of the motor is too large and the loss is too large to make the temperature exceed the allowable limit of the insulating material, the life of the insulating material will be shortened sharply.
In the forging production, according to the law of constant volume, it is possible to carry out technological calculations such as the size of the forging, the size of the process parts and the size of the mold.
China is in an important position in the international manufacturing industry, manufacturing technology is facing upgrade, and economic development is facing transformation. The increase in labor costs has made robot technology an important development opportunity in China, but the demand for robots in turn has put forward higher requirements for computer-related scientific research.
