3 de may. de 2024 · Assuming the shaft is mild steel, the minimum required shaft diameter is 48.7 mm. To calculate this result, follow these steps: Calculate the torque acting on the shaft from the power and shaft speed , using T = 60⋅P/(2π⋅n) = (60 × 20 × 10 3 )/(2π⋅200) = 955 N-m .
14 de may. de 2018 · Answer: Given data. Power (P) = 200kW = 200 x 10 3 W. Speed (N) = 1200RPM. Operating Torque (T Operating) = ? The maximum torque that can be operated on the shaft = 30% to the operating torque. T Max = 1.3 x T Operating. We have power (P) = (2 π N T)/60 = (2 x 3.14 x 1200 x T)/60. 200 x 10 3 = 125.6 x T.
The shaft diameter used for calculating the stress should be the smallest diameter of the shaft that carries torsional load. For most centrifugal pumps theshaft diameters gradually increase toward the center of the shaft span.
17 de dic. de 2011 · Another way to design a shaft is to calculate the minimum diameter needed to prevent torsional deflection (twisting) during service, meaning for engineers that the allowable twisting moment, or torque, is a function of the allowable torsional shearing stress (in PSI or kPa) and the polar section modulus (a function of the cross-sectional area of...
11 de mar. de 2021 · Uniform diameter shafts have the same diameter along their entire length, making them easier and more cost-effective to produce. Stepped shafts have varying diameters along their length to handle different stress levels in a mechanical system and, in some cases, to keep bearings in place.
The angular deflection of the shaft can be calculated as. θ = L T / (J G) = L T / (( π D 4 / 32) G) = (1 m) (1000 Nm) / ( ( π ((0.05 m) 4 - (0.03 m) 4) / 32) (79 10 9 Pa)) = 0.023 radian) = 1.4 o . Example - Required Shaft Diameter to Transmit Power. A 15 kW electric motor shall be used to transmit power through a connected solid shaft.
