CF-A OG Types - CENTAFLEX - MIKI PULLEY COUPLINGS - MIKI PULLEY VIETNAM

Power is transmitted by highly elastic rubber.Rubber is excellent at absorbing vibration and shock and also reduces machinery noise. The rubber components of the elastic body are constructed of polygonal rubber with aluminum inserts inserted into their tips. Each is formed by rigid vulcanizing adhesion. These rubber bodies are coupled by bolts in the radial and axial directions of the cylindrical hub and flange hub so that power is transmitted via the rubber body. The bolt coupling in the radial direction is particular has a pre-compressed construction and enables power transmission that is excellent in flexibility and absorption of vibration and shock.

*The values of the above table are for a flange hub with pilot bore when L = 500.

*Max. rotation speed does not take into account dynamic balance.

*The dynamic torsional stiffness is about 1.3 times that of the static torsional stiffness.

*Pilot bores are to be drilled into the part. Minimum values for d2 are given by the minimum bore diameter values in the MIKI PULLEY standard hole-drilling standards and maximum values from the maximumallowable drilled bore diameters.

*The nominal diameters for bolts M1/M2 are equal to the quantity minus the nominal diameter of the screw threads, where the quantity is for one side.

*The L dimension has a standard length of 1000 mm or less. Dimension L must at least allow enough space for an M1 bolt to be mounted.
