Pure aluminum has a low density (ρ=2.7g/cm3), about 1/3 of that of iron, and a low melting point (660°C). Aluminum has a face-centered cubic structure, so it has high plasticity (δ: 32~40%, ψ: 70~90%), easy to process, and can be made into various profiles and plates. ...
The tooth end of the outer gear sleeve of the star coupling is in the shape of a horn, so it is not suitable to be used under high speed and impact load conditions, and it is not suitable for the connection of vertical shafts. ...
There are hundreds of types of gear couplings, but there are two basic forms: 1. Combination of internal and external teeth; 2. Combination of end gears.Other forms are deformations on these two foundations. ...
The ZL-type elastic pin gear coupling realizes the coupling of the two halves of the coupling through the pin transmission torque.After the individual parts of the coupling are processed, the next step of assembly work is required.The main components are the two halves of the coupling and the outer ring, several nylon rods, two baffles...
1) Due to the variety of brakes, the more complex structure, and the more precise parts, special tools should be used during disassembly and assembly, and no knocks on the datum or finishing surface of the main parts are allowed to avoid collisions and prevent damage; for rubber cups Be careful when disassembling and installing the seal...
Since the 20s, the former Soviet Union, the United States, Germany, the Czech Republic and other countries have successively formulated some basic standards for couplings.For example, the former Soviet Union formulated ROCT60—1973 "Mechanical Coupling Nominal Torque Series" in 19107, which unified various types of coupling...
