© Siemens AG 2011 FLENDER Standard Couplings Torsionally Rigid Gear Couplings — ZAPEX ZN Series Customized hub design for ZAPEX ZN Series ■ Selection and ordering data ZAPEX couplings can be provided with customized S-dimensions and hub lengths. The entire dimension S results from the sum of the individual measurements SF1 and SF2. SF1 and SF2 are the measurements from the interstice of the coupling ring flange up to the beginning of the respective hub. As standard SF1 and SF2 are identical to each other and the entire S-dimension arises in accordance with them. SF1 and SF2 can be chosen different on customer request, however the minimal and maximum values of the following table have to be observed. Within these limits the measurements SF1 and SF2 may be chosen freely. The distance VA of the coupling teeth, the permitted bore diameter and the hub diameter remain unchanged. By stating the hub S-dimension and both hub lengths the coupling is completely described. Interstice 5 Part 1 SF1 min. NL Standard S = SF1 + SF2 SF2 max. Part 2 NL Special (450) 655-7447 info@pt-dstech.com www.dstech.ca NL Special S = SF1 + SF2 NL Standard G_MD10_EN_00183 SF1 max. SF2 min.

If there‘s no other possibility, for hub lengths smaller than standard hub lengths the order codes Y50 for part 1 and Y51 for part 2 must be stated in plain text. Order code for hub prolongations (Y4.); Std-NL = Standard hub length Part 1 Selected (special) hub length Order code min. max. > Std-NL ≤ 1.25 · Std-NL Y40 (specification of hub length in plain text) > 1.25 · Std-NL ≤ 1.5 · Std-NL Y42 (specification of hub length in plain text) > 1.5 · Std-NL ≤ 1.75 · Std-NL Y44 (specification of hub length in plain text) > 1.75 · Std-NL ≤ 2·Std-NL Y46 (specification of hub length in plain text) > 2·Std-NL Y48 (specification of hub length in plain text) Product code The product code of the respective ZAPEX coupling type must be supplemented with -Z and order codes for no standard SFdimensions (order code Y38 for part 1 and Y39 for part 2). For no standard hub lengths the order codes Y40 to Y49 must be specified (see the table below). Ordering example: ZAPEX coupling ZNN 130, variant A Hub left: bore D1 = 70H7 mm, keyway to DIN 6885-1 P9 and set screw; NL1 = 110 mm; SF1 = 10 mm Hub right: bore D2 = 75H7 mm, keyway to DIN 6885-1 P9 and set screw; NL2 = 75 mm; SF2 = 25 mm Product code: 2LC0330-2AA99-0AA0-Z L1G M1H Y38 Y39 Y41 Y46 plain text to Y38: SF1 = 10 mm plain text to Y39: SF2 = 25 mm plain text to Y46: NL1 = 110 mm plain text to Y41: NL2 = 75 mm Part 2 Selected (special) hub length Order code min. max. > Std-NL ≤ 1.25 · Std-NL Y41 (specification of hub length in plain text) > 1.25 · Std-NL ≤ 1.5 · Std-NL Y43 (specification of hub length in plain text) > 1.5 · Std-NL ≤ 1.75 · Std-NL Y45 (specification of hub length in plain text) > 1.75 · Std-NL ≤ 2·Std-NL Y47 (specification of hub length in plain text) > 2·Std-NL Y49 (specification of hub length in plain text) 1275 Newton, local 15 Boucherville, Qc, Canada, J4B 5H2 5/12 Siemens MD 10.1 · 2011
