RCT Torsionally Stiff Flange Couplings for Pump Drives

D2C – Designed to Customer The guiding principle of Designed to Customer is the recipe for success behind REICH. In addition to the catalogue products, we supply our customers with couplings developed to their specific requirements. The designs are mainly based on modular components to provide effective and efficient customer solutions. The special nature of our close cooperation with our partners ranges from; consulting, development, design, manufacture and integration to existing environments, to customer-specific production, logistics concepts and after-sales service - worldwide.

General Technical Description RCT Torsionally Stiff Flange Couplings for Pump Drives With RCT couplings REICH offers an optimal drive solution for As a supplementary service, REICH also offers a multitude of the connection of diesel engines to hydraulic pumps. Due to the bellhousing flanges through which the vast majority of combustion torsionally stiff design of the RCT coupling, critical resonances engines and hydraulic pumps can be connected. can be shifted into the range above the operating speeds. This enables sub critical operation of the drive without passing through REICH can also...

All components that can rust are protected against corresponding coupling elements. It is the customer’s/user’s responsibility to ensure there are no inadmissible loads acting on any of the components. In particular, existing connections, e.g. REICH have an extensive range of couplings and coupling...

Coupling Information Selection of the Coupling Size Usually the layout of the RCT coupling is based on the drive torque. A general safety factor of S = 1.1 to 1.3 should be applied. Torsional vibration analysis can be undertaken on request. In selecting the coupling size the following should be satisfied: The nominal torque capacity of the coupling TKN shall be at least equal to the drive torque while taking the layout factors into account. Calculate the driving torque TAN Given a driving power PAN and a coupling speed nAN, the driving torque is calculated as follows:

Coupling Information Permissible shaft displacement The permissibility of major shaft displacements depends on a number of factors such as coupling size, shore hardness of the element, operating speed and torque load of the coupling. The reference values listed below refer to an operating speed of ≈ 1 500 min-1. Precise alignment prevents premature wear of the rubber element. Observe the operating instructions.
