Standard parts refer to the commonly used parts (parts) produced by the factory, such as threaded parts, keys, pins, rolling bearings, etc., that have been fully standardized in various aspects such as structure, size, drawing method, and marking.The broad sense includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts.The narrow sense includes only standardized fasteners.Standard parts commonly known in China are the abbreviations of standard fasteners, which are narrow concepts, but the existence of broad concepts cannot be ruled out.In addition, there are industry standard parts, such as automobile standard parts, mold standard parts, etc., which also belong to broad standard parts.Generalized standard parts Generalized standard parts are mechanical parts (parts) and components with clear standards. The main standards used are Chinese Standards (GB), American Society of Mechanical Engineers Standards (ANSI /ASME), etc., other Japan (JIS), Germany (DIN) and other standards are also widely used in the world.Learn more and follow the WeChat public account Gongpin No.XNUMX
Mechanical parts and components with a high degree of standardization and strong industry versatility are also called general-purpose parts.
Generalized standard parts include fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs, etc., all have corresponding standards, and they have strong cross-industry versatility.
Industry standard parts, this concept belongs to the convention in the industry, and there is no clear stipulation.Commonly used industry standard parts are mold standard parts and automobile standard parts.When a product is widely used in the industry, it is a general-purpose part; the general-purpose part standard is usually formulated by enterprises in the industry and is widely accepted in the industry, so enterprise standards...

Industry standard parts, this concept belongs to the convention in the industry, and there is no clear stipulation.Commonly used industry standard parts are mold standard parts and automobile standard parts.When a product is widely used in the industry, it is a general-purpose part; the general-purpose part standard is usually formulated by the company in the industry and is widely accepted in the industry, so that the corporate standard becomes the de facto industry standard, and it can be called the industry standard part. .
Standard parts of molds are highly standardized in the mold industry at present, including injection mold bases, push rod push tubes, hot runner molds, etc.
There are many kinds of automobile standard parts, such as spark plugs, door locks, shock absorbers, automobile fasteners, etc. For details, please refer to the "Automobile Standard Parts Manual".
The more mature an industry, the higher the degree of standardization and generalization, the more standard parts, and the lower the industry cost.However, it is necessary to avoid excessive standardization, which leads to monotonous product categories in the industry and low-end competition.Generalized standard parts types connecting parts 
(Also used as: connectors) include threaded connectors (also known as fasteners) and hub connectors, pin connectors, riveted parts, glued parts, welding parts and other fasteners (see below)
Belt drive
Chain drive
Gear transmission parts: including involute cylindrical gears, bevel gears and worms, etc.
Friction wheel

These parts can hardly be said to be mechanical standard parts, but they are highly standardized and have strong relevance to the machinery industry; including: lubricating oil, grease and lubrication devices, lifting and handling parts and operating parts (pulley ropes, etc.), motors and travel switches ,and many more.
In addition, there are commonly used materials, such as cast iron, cast steel, steel and steel, copper and alloys, aluminum and alloys, engineering plastics, rubber products, composite materials and other non-metallic materials and products, with a high degree of standardization and generalization and strong relevance .Narrowly defined standard fastener types Fasteners are actually a kind of connectors (connectors), but because of the wide variety of types and wide applications, they are counted as one type in actual use, or even referred to as standard parts for short.
