Coupling brings energy savings
According to the EuP Directive, couplings are not included in the “Eco-design framework for energy-using products”.However, through the practical application of ROBA-DS chip couplings, it can be seen that mechanical parts play an important role in the entire production and reduction of CO2 emissions. The ROBA-DS coupling developed and designed by Mary Drive Technology has strong torsional rigidity, but also has good bending adaptability and axial, angular and radial compensation performance.At present, the ROBA-DS series coupling can transmit a rated power of 24 000Nm. It is a highly reliable and durable coupling that can be used in a very harsh working environment.Its operating temperature range and power density can at least reach the level of other types of shaft couplings; if the size specifications, installation and use methods are appropriate, its life span is almost infinite.The chip coupling also has the advantages of wear resistance, maintenance-free and good torsional rigidity.Many couplings (about 50% to 80%) rely on friction to transmit torque, and the rest rely on matching bolts to transmit torque.When the load exceeds the torque of the friction transmission, there will be a small relative displacement between the plate couplings, which brings many defects and deficiencies.With the change in the size and direction of the load, relative displacement will occur between the various parts, resulting in the coupling in an unstable equilibrium state.
The relative movement between the pieces of the chip coupling will cause the pre-tightening force of the matching bolt to decrease, and the bending load on the bolt will increase, which will eventually cause the bolt to break.In order to avoid this evil effect, the manufacturer of the chip coupling usually restricts the transmission of alternating torque or takes other measures.Although there are clear regulations on the load-bearing capacity in the product catalog, users will generally choose larger couplings to avoid breakage of the matching bolts.
