Installation of mechanical equipment parts
Mechanical parts, also known as mechanical components, are the basic components of machinery, and they are non-detachable single parts that make up machinery and machinery. Since the emergence of machinery, there have been corresponding mechanical parts. With the development of mechanical industry, new design theory and method, new material and new technology, mechanical parts have entered a new stage of development.
1. Bolted locking device. Bolt connection itself has self-locking property and bears static load and is reliable under stable working temperature. However, under the action of shock, vibration and alternating load, the self-locking property is damaged. Therefore, the locking device should be added.
2. Key connection. The key is used to connect the shaft and the parts on the shaft. The key connection is characterized by simple structure, reliable operation and convenient assembly and disassembly. Keys are usually classified into loose keys, tight splines, and splines according to their construction and purpose.
3. Installation of sliding bearing. Sliding bearing is a kind of sliding friction bearing. It is characterized by reliable operation, stability, no noise, strong oil film vibration absorption capacity, therefore, it can withstand a large impact load.
4. Rolling bearing installation includes cleaning, inspection, installation and clearance adjustment.
5. The installation of gear transmission mechanism. The gear transmission mechanism has the advantages of accurate transmission, reliable transmission, compact structure, small volume, high efficiency, convenient maintenance and so on.
6. The installation of worm gear and worm drive mechanism. The worm gear and worm drive mechanism are characterized by large transmission ratio, accurate transmission ratio, stable transmission, low noise, compact structure and self-locking. The deficiency is that the transmission efficiency is low, the friction heat is large when working, and good lubrication is needed.
7. The installation of coupling. The coupling can be divided into two categories: fixed type and movable type.
