The main parts of construction machinery are: hydraulic oil, pistons and sealing rings of various oil cylinders and oil cylinder accessories, travel motor and rotary motor accessories, various pilot valves and throttle accessories, oil seals, and oil pipes. Engine parts, generators, batteries, fuses, solenoid valves, main boards, control panels, filter elements (hydraulic oil and air), crawlers, bucket teeth of excavators Now some manufacturers in China are making online shopping malls for accessories, such as Lianzhong Mall.


Drawing, what are the four categories of mechanical parts?
1. Shaft parts
As the most important shaft part, the spindle can be divided into four categories: light-duty spindle, medium-load spindle, heavy-duty spindle and high-precision spindle according to the size and type of load it receives during work.

2. Gear parts
According to the working conditions, gear parts can be divided into three categories: light-duty gears, medium-duty gears and heavy-duty gears.

3. Machine tool guide rail
Because it has a great influence on the accuracy of the whole machine tool, in order to prevent its deformation and wear, the guide rails of machine tools are usually made of gray cast iron.

4. Engine and transmission system parts
There are quite a lot of parts included, there are a large number of gears and various shafts, as well as parts that work at high temperatures, such as intake and exhaust valves, pistons, etc.

5. Reduce the weight of automobile parts
The materials selected to reduce self-weight should be lighter than traditional materials and can ensure business performance.
