Understand the use of stainless steel structural parts

Three points of attention for the casting of stainless steel structural parts, stainless steel has been used in construction since the 1920s, and it has a history of about 90 years. Today, stainless steel is used in all aspects of building structures, and its use is growing and its application range is expanding. Since the cooling and solidification rate of stainless steel structural parts in the metal mold is faster than that of the sand mold, and there is no tolerance, the stress generated during casting is greater than that of sand casting, and the tendency to crack is also greater, which is prone to insufficient pouring, cold isolation, Castings and other defects. Generally speaking:

Precision planetary gear reducer gear accessories processing and maintenance

Precision planetary gear reducer gear accessories processing and maintenance

The processing of gear parts of precision planetary gear reducer requires maintenance. First, the precision planetary gear reducer can only be installed on a flat, shock-absorbing and torsion-resistant support structure. Under no circumstances should a hammer be used to knock pulleys, couplings, pinions or sprockets onto the output shaft, as this will damage the bearings and shaft. The precision planetary gear reducer has the advantages of space saving, reliability and durability, high overload capacity, power up to 200KW, low energy consumption, superior performance, deceleration efficiency up to 95℅, low vibration, low noise, rigid cast iron box, high gear surface Frequency heat treatment, after precision machining, constitutes helical gears, bevel gears. The gear reducer is a special reducer for various reaction kettles. Its gears adopt Gleason quasi-hyperbolic tooth type and the gears are hard-toothed. It has the characteristics of large bearing capacity, low noise, long life, high efficiency and stable operation. The performance of the whole machine is far superior to that of cycloid reducer and worm gear reducer, and has been widely recognized and applied by users. The gear modulus in the precision planetary gear reducer is a very important knowledge point. The higher the modulus, the thicker the teeth. The modulus refers to the ratio of the tooth pitch t between the tooth profiles on the same side of the adjacent two teeth to the pi (m=t/π) in millimeters. Modulus is one of the most basic parameters of modulo gear teeth. The larger the modulus. If the number of gear teeth is constant, the radial dimension of the wheel is also larger. The module series standards are formulated according to the requirements of design, manufacture and inspection. For gears with non-spur teeth, the modules are different from the normal module mn, the end face module ms and the axial module mx, which are based on their respective teeth. The ratio of pitch (normal pitch, end face pitch and axial pitch) to pi is also in millimeters. For the bevel gear module, there are big end module me, average module mm and small end module m1. For tools, there are corresponding tool modules mo, etc., and the application of standard modules is very wide.

Is the gear industry developing in China?

Is the gear industry developing in China?

A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. Gears play a vital role in transmission. They are the "heart" of all mechanical equipment and the nerves of all mechanical equipment. If you want equipment such as arm commands, you must use good gears. At the end of the 19th century, the prototype of gears appeared in developed countries such as Europe and the United States, and with the passage of time, the principle of the tooth cutting method and the special machine tools and tools for cutting teeth using this principle appeared one after another. With the development of the industry, the stability of gear operation has been paid attention to. At present, China's gear manufacturing industry, during the "Tenth Five-Year Plan" period, has
