Q:What is equipment manufacturing and machinery manufacturing? What's the difference between them?

At present, other countries in the world, including international organizations, have not put forward the concept of equipment manufacturing. The concept of equipment manufacturing industry is unique to our country. Its formal appearance was seen in the central economic work conference in 1998, which explicitly stated: "we must energetically develop the equipment manufacturing industry."". (central economic work conference: Economic Daily, December 10, 1998, first edition) The core of the manufacturing industry is equipment manufacturing. People do not have the same understanding of equipment manufacturing industry, and there is no consensus definition and scope definition. It is generally believed that the manufacturing sector consists of the equipment manufacturing industry and the final consumer goods manufacturing industry. Equipment manufacturing industry is the general term of the industry which provides the production technology and equipment for the simple reproduction and extended reproduction of the national economy, namely the machine manufacturing industry for producing machines".

Q:Mechanical bearings, all types? Roughly

The separable bearing is composed of a raceway and a needle roller and cage assembly that can be arbitrarily assembled with a punched thin raceway (W) or a machined thick raceway (WS). A non separable bearing is an integral bearing consisting of a precision machined raceway and a needle and cage assembly. This type of bearing can bear one-way axial load. With small space, it is beneficial to the compact design of machinery. Most of them only use needle roller and cage assembly, and the installation surface of shaft and shell is used as raceway surface.

Q:Construction Engineering, moving equipment and stationary equipment, respectively

1, moving equipment refers to the rotating device driven by the drive (that is, energy consumption of equipment), such as pumps, compressors, fans, etc., the energy can be electric power, pneumatic power, steam power, etc..

Q:China mechanical net

There are mechanical product development and design, mechanical equipment transformation, mechanical equipment maintenance, data inquiries, standard inquiries, mechanical professional translation, mechanical CAD and other mechanical and technical services.

Q:What type of industry does the machinery and building accessories processing belong to?

There are only three tax categories in our country: 1 consumption tax, 2 VAT, 3 special tax (agriculture). Therefore, as long as the manufacturing or processing of industrial value added tax on enterprises. It has nothing to do with the economic nature, classification and categories of an enterprise.

Q:The building electrical iron pipe and the pipe line fixing member connected to what is called, what is called the iron pipe and the 86 fixed part of tin

This book is based on the characteristics of construction electrician, in accordance with the scientific, practical and applicable principles. The content is simple, the language is easy to understand, the form is illustrated, and the system, authority, operability is strong.

Q:What functions should be achieved in mechanical structure design?

The function of the mechanical structure is mainly realized by the geometry of the machine parts and the relative position between the parts. The geometry of a part is made up of its surface, and a part usually has a number of surfaces, some of which are in direct contact with the surface of other parts, and this part of the surface is referred to as the functional surface. The connecting part between the functional surfaces is called the join surface

Q:What are the safety protection equipment, machinery and equipment, construction machinery and accessories for construction enterprises?

As well as scaffolding, protective fence, all belong to the safety protection facilities, does not belong to the safety protection appliances. Safety protection tools are many, it is characteristic of the operator to carry, I will not list

Q:What are the mechanical drawing software?

The plane is mainly CAD and CAXA, there are some non mainstream mechanical engineer what, mainly engaged in your spare parts of machinery industry, roughness, form and position tolerance requirements, recommendations for CAXA, which symbols are readily available, there are standard parts library, mechanical symbols library etc..

Q:Definition of large mechanical equipment?

Usually, crane hoisting (make things up and down movement), operation mechanism (the mobile crane), luffing mechanism and slewing mechanism (the horizontal movement of goods), plus metal mechanism, driving device, control device and the necessary auxiliary assembly.
