2. Structural features of TNB BHDVV Ringfeder Germany shaft coupling:

- TNB BHDVV coupling manufactured by Ringfeder/Germany

- Couplings are available in 12 different sizes

- Diameter of borehole d1: 85-340 mm; d2: 85-340mm

- Outer diameter D1: 240-900 mm

- Overall length L: 270-690 mm

- Rotation speed: 1,100-4,100 1/min

- Torque T KN: 2,500-180,000 Nm

- Working environment: from -30 C to +100 C

- The coupling is designed with 2 hubs and a shock-absorbing rubber ring in the middle

- High seal after shock absorber is made from neoprene (Pb) or polyurethane (Vk).

Couplings are capable of reducing shocks and torsional vibrations, in addition to being oil resistant.

- When the claw ring is pulled back, the drive rotation direction can be easily checked. Coupling suitable for use in all rotation directions and installation positions

3. TNB BHDVV Ringfeder Germany shaft coupling applied in the steel industry:

Vietnam's steel industry is still young compared to other countries in the region. However, this is a potential industry and brings a lot of economic profit. Its manufacturing process is also very complex and has many strict requirements. Steel is a material used in most fields in today's industrialization, so the production process must be standard to get good products. Produce steel, needs to go through 5 main stages:

Ore processing => Making molten steel stream => Feed casting => Steel rolling => Galvanized coil and steel pipe.

TNB BHDVV shaft coupling is symmetrically designed for short axial distance, a combination of 2 hubs and a shock-absorbing rubber gasket. The collar easily replaces the elastomer without shifting the axis of the coupled machine.

Hubs are customized and hub materials are available and designed according to customer requirements.

The TNB BHDVV coupling is cross-resilient, so dangerous torsional vibrations from the machine's operating range are transferred to the rotational speed ranges without negative impact. Elastomeric buffers possess damping capabilities that enable the coupling to keep resonance enhancements within limits when traveling through dangerous speed ranges, thereby protecting coupled machines from damage.

TNB BHDVV coupling designed by advanced technology and experienced engineers has created a trust for users and become the first choice for many customers around the world.
