© Siemens AG 2015 FLENDER Standard Couplings Flexible Couplings — RUPEX Series Type RWB with brake disk to DIN 15432 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 = 1146/DB DB in m Observe maximum speed of type RWN! 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 RWN J 2 = J 2 from type RWN + 710 ⋅ BB ⋅ DB 4 BB and DB in m • Weight in kg: m = m from type RWN + 5700 ⋅ BB ⋅ DB 2 BB and DB in m Ordering example: RUPEX RWB coupling, size 252, Part 1:
Bore D1 = 48H7 mm, keyway to DIN 6885-1 and set screw, Part 3: Brake disk DB = 630; 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 + 3.3 kgm 2 = 3.42 kgm 2 Weight: m = 26.3 kg + 68 kg = 94.3 kg Article No.: 2LC0130-8AE99-0ZA0-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. 8/13 Siemens MD 10.1 · 2015
