Introduce:

The drum gear coupling is generally equipped with two O-rings during assembly, which mainly play a sealing role and reduce noise. In practice, the drum-shaped gear coupling mainly reflects the clearance and tolerance of the inner and outer teeth of the O-ring. If the clearance is too large, there will be a gap after the coupling O-ring is installed. , resulting in poor sealing. If the size gap and tolerance fit are small, it will make the installation of the O-ring inconvenient, or because the gap is too small, the drum gear coupling will not be operated and installed during the installation process.

The secret of the drum gear coupling O-ring:

The O-ring of the drum gear coupling is formed by rubber casting at one time. There are whole roots and whole rings, and their properties are the same. The material of the drum-shaped gear coupling is generally domestically produced. If the processing technology is simple, and the raw materials are relatively cheap, the price is relatively cheap. Because of their low price, simple manufacture, reliable function, and simple installation requirements, O-rings are the most common mechanical design for sealing. O-rings withstand tens of Pascals (thousands of pounds) of pressure. O-rings can be used in static applications as well as dynamic applications where there is relative motion between parts, such as shafts of rotary pumps and pistons of hydraulic cylinders.
