The theory of grinding burn refers to the metallographic changes that occur on the surface of a workpiece due to local high temperatures during grinding, especially when the surface of the workpiece is subjected to instantaneous high temperatures, resulting in uneven annealing, softening, blackening...

The principle of gear meshing detection refers to testing the accuracy and performance of gears by simulating their actual working conditions. There are usually two main measurement methods used: double-sided meshing and single-sided meshing. The following is a detailed explanation of these two ... Read More

1. Design and analysis: Use specialized software to accurately design gear parameters, considering modulus, pressure angle, number of teeth, center distance, etc., and conduct mechanical analysis to ensure the distribution of load bearing force. 2. Material selection: Select high-strength steel, ... Read More

For any sheet metal part, there is a certain processing process, also known as the process flow. Depending on the structure of the sheet metal part, the process flow may vary, but overall it does not exceed the following points 1. Design and draw the part diagram of its sheet metal parts, also known ... Read More

The structural diagram of the ball screw pair is shown in Figure 6, and the cross-sectional diagram of the screw, nut, and ball fit is shown in the following figure: picture Composition: The ball screw pair consists of a screw, nut, steel ball, ball guide tube, etc. The screw and nut threads are ...

The main differences between worm wheel gear grinding machines and forming wheel gear grinding machines are reflected in processing principles, processing efficiency, applicability, and machine tool structure. The specific analysis is as follows: 1. Working principle -The working principle of a worm ... Read More

The influence of gear meshing clearance 1. Gear wear and reduced lifespan: Excessive gear mesh clearance can exacerbate gear wear and reduce the service life of gears. This is because the gap is too large, causing sliding between the two tooth surfaces during the meshing process, resulting in wear. ... Read More

1. Feeler gauge method: This method can directly measure the top and side clearances of gears. Fill the feeler gauge on the tooth side of the gear, and the thickness of the feeler gauge is the meshing clearance. 2. Dial gauge method: This method can indirectly measure the backlash of spur gears. Fix ... Read More

The main functions of flanges include: Connection: The main function of flanges is to serve as connectors for pipelines or equipment, tightly fixing them together through bolts and nuts. Sealing: During the connection process, a gasket (such as rubber gasket, metal gasket, etc.) is usually placed ... Read More

The reason why flange is called "flange" is because its name comes from the transliteration of the English word "flange". It was first proposed by an Englishman named Elchat in 1809, who also proposed the method of casting flanges. Although flanges were not widely used in the initial period, by the ... Read More
