BevelGearBoxF-6Prime moverMotorRotation speedn=500rpmReduction ratio1:1Operating timeTwo hours/day (six, single operations of 20 minutes each)Load conditionsUniform loadingA 20 N-m load is applied to each of No. 3-a to No. 3-d.Rotation directionOne way as shown in the drawingShaft connection methodGear coupled with the gears directly connectedInstallation conditionsIndoors, horizontal installationThe equivalent output torque (T1) of the outputshaft (Shaft B) for each of the bevel gear boxesfrom No. 3-a to No. 3-d is as follows.T1=Pe×Sf1η=20N・m×0.8(load coefficient)/0.95(efficiency)=17N・mFrom the transfer capability table, select SB19(47N-m/500rpm)The torque (T2) required for the output shaft in theNo. 2bevel gear box drives No. 3-c and No. 3-d is:T2= 17N-m x two units/0.95(efficiency) = 36N-m. From Table 5, select SB19.T3=(17N・m×2+36N・m)/0.95=74N・mSelect SB25(110N・m/500rpm) from tableTherefore,No.1bevel gear box:SB25-1-113No.2bevel gear box:SB19-1-23Nos.3-a and 3-c bevel gear boxes:SB19-1-41Nos.3-b and 3-d bevel gear boxes:SB19-1-31Size selection example 2 (SB type)No.3-dNo.2No.3-cNo.3-bGearNo.1No.3-aMotorBevel gear box no-load input torque (N-m)SizeTwo shafts(11~83) Three shafts(111~183) SB19-1, 1.5 SB25-1, 1.5 SB30-1, 1.5 SB38-1, 1.5 SB19-2, 2.5, 3 SB25-2, 2.5, 3 SB30-2, 2.5, 3 SB38-2, 2.5, 3 SB45-1 SB50-1 SB65-1 SB75-1 SB85-1 SB45-2 SB50-2 SB65-2 SB75-2 SB85-2 0.45 0.50 0.60 0.65 0.40 0.45 0.55 0.60 0.90 1.50 3.56 4.50 6.50 0.80 1.40 3.00 3.50 5.50 1.10 1.20 1.50 1.70 1.00 1.10 1.40 1.50 2.30 4.00 7.00 8.0011.00 2.00 3.50 6.00 7.0010.00SizeNo-load torqueFB20-1 FB25-1 FB30-1 FB35-1 FB45-1 FB20-1.5 FB25-1.5 FB30-1.5 FB35-1.5 FB45-1.5 FB20-2 FB25-2 FB30-2 FB35-2 FB45-2 TB12-2-1 TB17-2-1 TB20-2-1 TB12-3-1 TB17-3-1 TB20-3-1 TB12-2-2 TB17-2-2 TB20-2-2 TB12-3-2 TB17-3-2 TB20-3-2 0,250.300.350.400.600.200.250.300.350.500.200.250.300.350.450.050.080.120.060.100.150.040.070.110.050.080.12※Since the torque may be different, depending on theshaft arrangement, please contact us.
