Example of designation of the ASM type coupling with the nominal torque of Mn=440 Nm, brake drum diameter of DH=320 mm, distance of the brake drum symmetry axis from the hub origin LH=100 mm, hub holes diameters of d1=60 mm, d2=50 mm, hub holes lengths of l1=65 mm, l2=70 mm, size of 003, in the C variant:
440-320-100-60/65-50/70-003 ASM-C Rubber membrane coupling
Variant:
A – detachable after dismounting the rubber membranes
B – detachable without dismounting the rubber membranes
C – „A” variant with brake drum
D – „B” variant with brake drum
* The distance of the brake drum symmetry axis from the hub origin
LH – concerns C and D construction; LH=l1+l0
