- Why Can't The Number of Teeth on A Gear Be Less Than 17?As an important component in mechanical transmission systems, gears need to follow many principles and standards in their design and manufacturing to ensure their normal operation and long-term durability. In gear design, the selection of the number of teeth is a key factor. The limitation that the
- DrillingDefinition of DrillingChinese name: DrillingEnglish name: drillingOther names: DrillingDefinition: The method of machining holes on a workpiece by relative motion and axial feed motion between the drilling tool and the workpiece.Drilling is the most basic method of hole machining. Drilling is often
- The Function of An Unpowered HoodA non powered hood is a ventilation device installed on the roof of a building, mainly used in residential, factory, warehouse and other places that require ventilation and exchange. Their main functions include:Improving indoor air qualityBy natural ventilation, indoor heat, moisture, smoke, and ha
- What Surface Treatment Is Phosphating And Why Multiple Colors Can Be ProducedIn the world of metal surface treatment, let's enter the world of phosphating technology together and explore why it can display a variety of charming colors.1、 Introduction to Phosphatization TechnologyPhosphating, also known as metal phosphating, is a process of forming a phosphate chemical conver
- A Bunch of Gear Parameters, First Understand M And Z?Why is d=m * z?!A bunch of gear parameters, first understand m and z?How to determine exactly, everything is related.The dividing circle is determined for defining gears.Okay, let's delve deeper into the two key parameters of gear modulus (m) and number of teeth (Z).Module (m):Module is a very impor
- What Does Roughness Size Mean in Practice?Roughness, everyone is quite familiar with it, so I won't go into too much detail here. However, there is a question that you can ask yourself: what does choosing a higher or lower roughness mean in practice? What is the physical impact it brings? For example, what exactly does choosing Ra3.2 and Ra
- Rolling processing technology can significantly improve various properties of partsSurface hardness: Rolling processing can form a hardened layer on the surface of the material, significantly improving its hardness. For example, after rolling, the hardness can be increased by 15-30%.Wear resistance: Rolling processing not only improves the hardness of the material, but also signif
- Brinell hardnessBrinell hardness (HB) is generally used when materials are softer, such as steel before heat treatment or after annealing. Rockwell hardness (HRC) is generally used for materials with higher hardness, such as hardness after heat treatment, and so on.Q355D hot-rolled steel plate hardness 140-190HBHar
- Corrosion Resistance of 300 Series Stainless SteelCorrosion resistance of 300 series stainless steelThe 300 series stainless steel is highly favored due to its excellent performance and wide range of applications. It has excellent corrosion resistance in humid, acidic or alkaline environments and is suitable for fields such as marine engineering, c
- The Main Chemical Composition Characteristics of 300 Series Stainless SteelThe main chemical composition characteristics of 300 series stainless steel:Chromium (Cr): Chromium is one of the most important elements in the 300 series stainless steel, which can form a dense oxide film to protect stainless steel from corrosion. The chromium content in 300 series stainless steel
