Required Information: Lewis Formula The Lewis formula is a simple approach to calculating the bending stress in gears, given by: σ=W_t/(K_v FmY) (N/m^2) Equation 1 Where: σ – bending stress in a gear (N/m2) W_t – transmitted load (N) (found by using Equation 2) K_v – velocity factor (found by using Equation 5) F – face width (m) m – module (m/tooth) Y – Lewis form factor Y (found in Table 1) The Load transmitted by the Gear W_t: W_t=Power/V (N) Equation 2 Where: W_t – transmitted load (N) Power – Power transmitted (W) V – pitch line velocity (m/s) The pitch line velocity V: V=d_p/2×ω (m/s) Equation 3 Where: V – pitch line velocity (m/s) d_p – pinion pitch diameter (m) ω – angular velocity (rad/s) The pinion pitch diameter d_p: d_p=m×N (m or mm) Equation 4 Where: m – module (m/tooth or mm/tooth) N – number of teeth The velocity factor K_v, given by the Barth equation: K_v=6.1/(6.1+V) (N/m^2) Equation 5 Where: K_v – velocity factor V – pitch line velocity (m/s) Table 1 – Values for the Lewis form factor Y defined for two different tooth standards (Mitchener and Mabie 1982) N, number of teeth Y (φ = 20°; a = m; b = 1.25 m) 12 0.22960 13 0.24317 14 0.25530 15 0.26622 16 0.27610 17 0.28508 18 0.29327 19 0.30078 20 0.30769 21 0.31406 22 0.31997 24 0.33056 26 0.33979 28 0.34790 30 0.35510 34 0.36731 38 0.37727 45 0.39093 50 0.39860 60 0.41047 75 0.42283 100 0.43574 150 0.44930 300 0.46364 Rack 0.47897 a – addendum b – dedendum φ – pressure angle m – module Table 2 – Permissible bending stresses for various commonly used gear materials Material Treatment σUTS (MPa) Permissible bending stress σp (MPa) Nylon 65 (20°C) 27 Tufnol 110 31 080M40 540 131 080M40 Induction hardened 540 117 817M40 772 221 817M40 Induction hardened 772 183 045M10 494 117 045M10 Case hardened 494 276 655M13 Case hardened 849 345 Example 1: A 20° full depth spur pinion is to transmit 1.25 kW at 850 rpm. The pinion has 18 teeth. Determine the Lewis bending stress if the module is 2 and the face width is 25 mm: Step by step solution: Calculate the pinion pitch diameter from Equation 4: d_p=m×N=2 mm/tooth×18 teeth=36 mm=0.036 m Calculate the pitch line velocity from Equation 3: V=d_p/2×ω =0.036/2×850×2π/60=1.602 m/s Calculate the velocity factor from Equation 5: K_v=6.1/(6.1+V)=6.1/(6.1+1.602)=0.792 (N/m^2) Calculate the transmitted load from Equation 2: W_t=Power/V=1250/1.602=780.2 (N) Calculate the bending stress load from Equation 1, taking the Lewis form factor Y from Table 1 for 18 teeth Y=0.29327: σ=W_t/(K_v FmY)=780.2/(0.792×0.025×0.002×0.29327)=67.18 (MN/m^2) Example 2: A gearbox is required to transmit 18 kW from a shaft rotating at 2650 rpm. The desired output speed is approximately 12 000 rpm. For space limitation and standardisation reasons a double step-up gearbox is requested with equal ratios. Using the limited selection of gears presented in Tables 2 to 5, select suitable gears for the gear wheels and pinions. Step by step solution: The steps are the following: Sketch the solution Find the gear ratio Select a material Select a gear from the table by rearranging the Lewis equation (Equation 1) to find the gear face width F and. Finding the gear ratio: G=(12 000 rpm)/(2650 rpm)=4.528 Total gear ratio of 1 to 4.528. A double gearbox is requested with equal ratios. Therefore the ratio for each gear pair should be: √G=√4.528=2.128 Note that the minimum number of teeth permissible when using a pressure angle of 20° is 18. This means the small gear needs to have 18 teeth. So the large gear should have approximately: 18×G=18×2.128=38.3 The nearest integer is 38. This gives us a real gear ratio of 38/18=2.11 for each gear pair. Selecting a material: The next step is to select a material. The stronger steel in Table 2 is the 655M13 which will be selected prior to a more detailed consideration. For 655M13, the permissible bending stress is σ_p=345 MPa. Calculations for gear 1 with 38 teeth: Y = 0.37727 from Table 1. The shaft is rotating at 2650rpm we will do the equations for modules 1.5 and 2.0 to test if any of the gears are usable (in this example only modules of 1.5 and 2.0 are used, to simplify but in reality all modules should be checked): Module m (in mm/tooth) 1.5 2.0 Calculate the pinion pitch diameter from Equation 4: d_p=m×N (mm) 57 mm 76 mm Calculate the pitch line velocity from Equation 3: V=d_p/2×ω (m/s) 7.9 m/s 10.5 m/s Calculate the velocity factor from Equation 5 K_v=6.1/(6.1+V) 0.4357 0.3675 Calculate the transmitted load from Equation 2: W_t=Power/V (N) 2276 N 1707 N Calculate the face width by rearranging Equation 1 F=W_t/(K_v σmY) 0.027 m 0.018 m From our calculations the gear with module 1.5 requires a face width of 27mm which is larger than the 20 mm from the catalogue in Table 4. The gear with module 2.0 requires a face width of 18 mm which is lower than the 25 mm from the catalogue in Table 5. Calculations for pinion 1: Y = 0.29327 from Table 1 and n = 5594 rpm (after adjusting by using the gear ratio). (no need to calculate for m = 1.5 as it has been rejected) Module m (in mm/tooth) 2.0 Calculate the pinion pitch diameter from Equation 4: d_p=m×N (mm) 36 mm Calculate the pitch line velocity from Equation 3: V=d_p/2×ω (m/s) 10.5 m/s Calculate the velocity factor from Equation 5 K_v=6.1/(6.1+V) 0.3676 Calculate the transmitted load from Equation 2: W_t=Power/V (N) 1707 N Calculate the face width by rearranging Equation 1 F=W_t/(K_v σmY) 0.023 m For the second pair of gears, rinse and repeat, do all the steps for all the modules. From my calculations m = 1.5 gives a face width value greater than the catalogue value of 20 mm, so try m = 2 which gives a face width value less than the catalogue value of 25 mm, so design is OK. Let’s run the calculations for the second gear with 38 teeth: Y = 0.37727 from Table 1 and n = 5594 rpm (it’s in contact with Pinion 1) Module m (in mm/tooth) 2.0 Calculate the pinion pitch diameter from Equation 4: d_p=m×N (mm) 76 mm Calculate the pitch line velocity from Equation 3: V=d_p/2×ω (m/s) 22.26 m/s Calculate the velocity factor from Equation 5 K_v=6.1/(6.1+V) 0.215 Calculate the transmitted load from Equation 2: W_t=Power/V (N) 808.6 N Calculate the face width by rearranging Equation 1 F=W_t/(K_v σmY) 0.0144 m Calculations for pinion 2: Y = 0.29327 from Table 1 and n = 11810 rpm (after adjusting by using the gear ratio). Module m (in mm/tooth) 2.0 Calculate the pinion pitch diameter from Equation 4: d_p=m×N (mm) 36 mm Calculate the pitch line velocity from Equation 3: V=d_p/2×ω (m/s) 22.26 m/s Calculate the velocity factor from Equation 5 K_v=6.1/(6.1+V) 0.215 Calculate the transmitted load from Equation 2: W_t=Power/V (N) 808.6 N Calculate the face width by rearranging Equation 1 F=W_t/(K_v σmY) 0.0186 m 18.6 mm is below the catalogue value of 25 mm so design is OK Challenge: +Solve questions 8, 9, 10, 11, 12, 13, 14 and 15 from the Tutorial on Gears. +Solve the question below: A gearbox is required to transmit xx kW from a shaft rotating at yyyy rpm.
