2. Characteristics of Renold Flexible Couplings PM
– Manufacturer brand: Renold/England.
– The Renold PM coupling is made of steel.
– Maximum torque: 7000 kNm.
– The driving flange, ranging from PM60 and including PM7000, is forged steel to BS970 grade 070 M55.
– The driving flange from PM90 to PM7000, and all internal and external components up to PM7000, are cast steel to BS 3100 grade A4.
– The rubber elements are fully encapsulated and individually encased with options for grade and hardness, with styrene-butadiene rubber with a hardness of 60 (SM60) being the standard. Rubber elements are loaded in compression.
– It protects and prevents controller failure under the influence of high torque passing through.
– Ensures continuous operation of the drilling machine in case of unfortunate rubber breakdown or damage.
– No lubrication or adjustment is required, resulting in low operating costs.
– Achieves low vibration loads in the transmission components by selecting optimal stiffness characteristics.
– Eliminates torque amplification by pre-compressing the rubber elements.
– Allows for axial and radial misalignment between the driving and driven machinery.
