Taper Grid Coupling - Benefits of DNEO Grid couplings

1. When overloads occur, a grid will break and it will prevent breaking shafts or machinery parts.

2. When the parallel misalignment is too severe, the related machine is protected by the shearing grid on the sawtooth.

3. The life of parts (Mechanical Seal and Bearing, etc) is twice the normal lifespan.

4. Quick installation and easy maintenance reduce labor cost and downtime cost.

5. DNEO coupling is 99% interchangeable with international major brands. 

6. It always transmits power (99%) with low noise.

+Details

DNEO Tapered Grid Couplings are shaft-to-shaft couplings that are compact in size, you can handle torque capacity due to their high strength hardened alloy steel construction. The tapered grids are designed with a trapezoidal cross-section and are tempered for spring hardness. Through a high-precision operation called shot peening, the surface molecules are compressed by high-velocity steel microbeads. The compression of the molecules results in a dramatic increase in strength rating and will provide reserved strength for a greater proportion of the unit's lifespan. The tapered grids are accessible through the unit removable cover.  It is extremely easy to fit the trapezoidal grids into the slots of the hub, compared to fitting rectangular grids.   There is no need for the equipment to be moved so that couplings can be installed. Due to their compact size, the tapered grids can simply be placed directly in the slots of the hub. Finally, the practical split cover can be placed using standard tools.

Protection Against Shaft Misalignment
The tapered grids are free from shock, rotation, and coplanarity within the hub teeth. This provides a generous capacity for misalignment without producing the detrimental side loads on the bearings that are often created when couplings are misaligned.

Protection Against Shock & Vibratory loads 

Tapered Grid Couplings are able to deflect torsionally when subjected to normal shock or vibratory loads, so they are able to handle changing load conditions. The system truly is a shock absorber for rotary motion, relying on the predictable resilience of the grid for torsional flexibility. The tapered grids 'tune' the drive system. Due to their spring hardness, the grids absorb impact by spreading the impact energy over time. The grids can also damp vibration and reduce the peak or shock loads experienced by the rest of the system.
