Q:Mechanical bearings, all types? Roughly

The basic structure and NU type cylindrical roller bearing inner ring bearing the same, but because of the needle, the volume can be reduced, and can bear large radial load to the bearing without inner ring shaft mounting surface with suitable precision and hardness is used as a raceway.

Q:What are the mixing arms of the concrete mixer?

Mixing arm concrete mixer is a component of the mixing arm itself and divided into lateral mixing arm (positive and negative points), stirring arm (also have positive and negative points), stirring arm below is the bearing seat connected, connected with 4 sets of high strength bolts with stirring arm. The top is equipped with wear-resistant mixing blades, connecting with mixing blades, high-strength bolts 2 sets. In addition, some manufacturers have designed mixing side bonded shaft swivel, is installed in the interval between the stirring arm fixed and rotated in two ways.

Q:What is the difference and connection between equipment manufacturing and machine building?

In accordance with the standards of classification, including metal products, general machinery manufacturing, machinery manufacturing, transportation equipment manufacturing, electronic and communication equipment manufacturing industry, electrical machinery and equipment manufacturing, instrumentation and office machinery manufacturing seven deducted 186 small consumer related manufacturing industry after class. Equivalent to the European countries referred to as "capital goods manufacturing", that is, we often say "the production of means of production industry."".

Q:How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?

The whole circle of the triangle is welded as an angle weld, and the other is the outer circle with the same diameter as the two, so the butt joint is better to open the groove. Welding, for V type welding seam, and, technical requirements are generally, welding firm, no defects, welding smooth grinding, cleaning welding slag splash

Q:What measures can effectively reduce the construction accident rate?

Hefei construction workers training _ limited energy or hazardous substances: conditions of actual technical and economic constraints, some risk sources can not be eradicated, then they should try to limit with energy or hazardous substances, reduce the risk of. Reduce the amount of energy or dangerous substance.

Q:What are the mechanical drawing software?

The 3D map only contact with SolidWords and Pro/E, Pro/E is better than Solidwords in general, but Solidwords is very simple to use, see Help tutorials you can learn to draw a three-dimensional map is not particularly complex easily to estimate a few days is enough. But any one of the two kinds of software, want to do not understand the words, expert advice is not really easy. UG and MasterCAM haven't touched much, but I've heard that it's suitable for processing stereogram.

Q:Definition of large mechanical equipment?

The hoisting machinery used in bridge construction can be divided into three categories: light and small lifting equipment, bridge type crane and boom type crane. Light and small lifting equipment, such as jacks, hoists, winches, etc.. Bridge type lifting machinery, such as beam cranes, Longmen cranes and so on. Boom type cranes, such as stationary slewing cranes, tower cranes, truck cranes, tires, crawler cranes, etc..
