22 SCHMIDT L200 & 300 SERIES OFFSET COUPLINGS How To Select L200 & L300 Schmidt Offset Couplings Example: Step 1. List the performance requirements a) Horsepower H=55 (HP) b) Shaft Speed N=1000 (RPM) c) B-10 Bearing Lifetime B-10=25000(HRS) d) Offset From Fixed Shaft PH=2 (INCH) e) Variable Offset (if required) PA=5 (INCH) Step 2. Select a coupling with the required offset characteristics. All offset couplings have a minimum offset (Smin), a maximum offset (Smax) and a maximum linear range of shaft displacement (Sml). For applications where the offset distance between shafts remains FIXED, simply select a coupling with an offset larger than Smin and smaller than Smax. For applications where the shaft offset distance VARIES during operation, select a coupling where the linear range of displacement is less than the Sml. Note: At no time can the shafts be separated by more than Smax nor less than Smin. To use all of Sml, X (see diagram below) must be equal to Smin and PH must equal PA/2. Consult dimension chart on page 6. Shaft Speed N (rpm) Lifetime-Speed Factor L B-10 Lifetime (Hours) 1,000 2,500 5,000 10,000 25,000 50, Center of Fixed Shaft , , , S min S ml 1, , PA 1, , S max D PH 1, , , , NOTE: X S min PA S ml S min D S max Step 3. Select the lifetime speed factor L from chart to the right. For N=1000 (RPM) and B10=(25000) (HRS) L=6.034 Step 4. Calculate the required performance factor P r =H/L=55/6.034=9.115 Step 5. Compare the required performance factor Pr with the coupling performance factor P listed on the performance data table on page 6. Select a coupling size which has an equal or higher P factor as Pr. The coupling size L280C meets these requirements. Step 6. Compare the practical speed limit (see performance data table on page 6). The data shows that the coupling size L280C can operate at 1500 RPM. Step 7. Select hubs (if required) from chart on page 11. X 2, , , , , The L200 & L300 Series couplings use needle bearings. The B-10 lifetime on the bearing is considered the life of the coupling, assuming that the bearing is the weakest part in the coupling. The lifetime-speed factor accounts for the B-10 lifetime and shaft speed.
