© Siemens AG 2015 FLENDER Standard Couplings Flexible Couplings — RUPEX Series Type RBS with brake disk to DIN 15432 Sizes 144 to 360 Brake disk diameter DB in accordance with customer specification. Additional sizes are available on request. Further dimensions for part 3 on request. Maximum speed in rpm: n Kmax = 1528/DB DB in m Observe maximum speed of type RWS! Mass moments of inertia and weights can be sufficiently pre- cisely determined as follows: • Mass moments of inertia in kgm 2 : J 1 = J 1 from type RWS J 2 = J 2 from type RWS + 770 ⋅ BB ⋅ DB 4 BB and DB in m • Weight in kg: m = m from type RWS + 6160 ⋅ BB ⋅ DB 2 BB and DB in m Ordering example:
RUPEX RBS coupling, size 252, Part 1: Bore D1 = 48H7 mm, keyway to DIN 6885-1 and set screw, Part 3: Brake disk DB = 630 x BB = 30 mm, D6 = 350 mm, bore 42H7 mm, keyway to DIN 6885-1 P9 and set screw. Hub reduced to NL2 = 200 mm Coupling micro-balanced G6.3 at 1500 rpm in accordance with the half parallel key standard. Mass moment of inertia: J 1 = 0.07 kgm 2 J 2 = 0.12 kgm 2 + 3.6 kgm 2 = 3.72 kgm 2 Weight: m = 25.8 kg + 73 kg = 98.8 kg Article No.: 2LC0130-8AH99-0ZA0-Z L1B+M0X+P0Y+W02 Plain text to P0Y: DB = 630 mm; BB = 30 mm; D6 = 350 mm; NL2 = 200 mm 8 The article number applies to standard buffers of 80 ShoreA; the article number for alternative buffer types is available on re- quest.
