Flange Coupling (YL Series)

Flange Coupling (YL Series)

Description
Flange coupling is used to bring two half couplings together for the purpose of transmitting movement and torque. It belongs to rigid coupling. This shaft coupling mainly has two structures. The first is to transfer torque by using reamed hole bolt. The second is to achieve centering by the mutual coordinate of bending in one half coupling and groove in another coupling.

Application
Flange coupling is widely used in low speed, shock-free and high rigidity occasions. This shaft coupling belongs to rigid coupling. It is applicable to line shafting of concentric line with 63 to 100000 N.m transmitting torque.

Features
1. The structure of flange coupling is simple, thus it has the advantages of low cost and convenient in installation.
2. Shaft coupling has good rigidity and is able to transfer stronger torque.
3. Flange coupling can be made up of gray cast iron or carbon steel. When it comes to heavy load or the circular velocity is more than 30 m/s, shaft coupling is made up of cast steel or forged steel.

Notes
1. The weight and rotational inertia are approximately calculated according toⅠtype shaft coupling with minimum diameter and maximum length.
2. Axle holes with identical type can be randomly combined.

We implement strict quality control system and perfect testing system in order to ensure the quality of shaft couplings. Flange couplings have won widespread praise and recognition by customers both home and abroad.
