The surface roughness of the coupling refers to the small spacing and small peak and valley unevenness of the machined surface.The distance (wave distance) between the two wave crests or two wave troughs is very small (below 1mm), and it is difficult to distinguish with the naked eye, so it belongs to the microscopic geometric shape error.The smaller the surface roughness, the smoother the surface.
The characteristics of the JQ type clamp coupling are similar to those of the clamp coupling, simple structure, easy to assemble and disassemble, suitable for low speed (high peripheral speed of XNUMXM/S), no impact, and stable vibration load occasions. For the connection of vertical shafts such as agitator.
YL flange coupling can be made of gray cast iron or carbon steel, and cast steel or forged steel should be used for heavy loads or when the peripheral speed is greater than 30 m/s. The YL flange coupling has high requirements for the neutrality of the two shafts. When the two shafts have relative displacement, it will cause additional loads in the machine parts and worsen the working conditions.
