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:

Talking about several failures of gears

Talking about several failures of gears

When we use gears in our life, we often encounter the situation of gear failure, so in what environment is the gear more prone to failure, today we will talk about several methods of gear failure. 1. Failure due to fatigue pitting Since the gears are always in cyclic motion, and the orientation of the meshing point is constantly changing, under the effect of long-term force, small cracks will gradually appear at the knife marks on the tooth surface. When it is long, the cracks will increase, which will constitute the phenomenon of fatigue pitting. 2. Failure due to plastic deformation of the tooth surface. The so-called plastic deformation is the deformation of the curved surface of the tooth profile. This situation is generally due to the overloading of the mechanism.
