Design of Shafts and Shaft Components

The shaft is basically defined as the machine element that rotates, is in circular cross-section, it is majorly used to transfer the power from one part of the system to another, or from a power generating machine to a power absorbing machine. The shaft is supported on bearings and is rotated with the help of a set of gears or pulleys that are used for the power transmission. Bending moment, torsion, and an axial force act upon the shaft. Designing of shaft primarily involves determining stresses at a critical point in the shaft that is arising due to loading.

A motor supplies 173 hp at 650 rpm to flange A of the shaft. Gear B transfers 75 hp of power to operating machinery in the factory, and the remaining power in the shaft is transferred by gear D. Shafts (1) and (2) are solid aluminum [G = 4400 ksi] shafts that have the same diameter and an allowable shear stress of T = 5.8 ksi. Shaft (3) is a solid steel [G=9100 ksi] shaft with an allowable shear stress of T = 10.2 ksi. Assume that L₁=2.3 ft, L₂=1.2 ft, L3-2.9 ft. Determine: (a) the minimum permissible diameter d₁=d₂ for aluminum shafts (1) and (2). (b) the minimum permissible diameter d3 for steel shaft (3). (c) the rotation angle D/A of gear D with respect to flange A if the shafts have the minimum permissible diameters as determined in (a) and (b).

The two solid shafts are connected by the gears shown. The motor constantly supplies 20 kW of power at 15 Hz to system at A. The yield shear stress is 140 MPa for shaft (1) and 220 MPa for the shaft (2), and over all factor of safety is 2. a) Find the diameter of both shafts. b) If the modulus of rigidity of shaft (2) G is 77.2 GPa, calculate the relative angle of twist D with respect to C. 30 teeth B (1) 48 teeth Tp 0.8 m
The shear modulus of the solid steel shaft is G = 11 x 10° ksi. Motor A is directly coupled to the shaft and delivers 3 hp while rotating at 1800 rpm (revolutions per minute). Gears B, C, and D remove the powers indicated in the figure. Given the following two criteria, determine the required diameter of the shaft to the nearest 1/s in. (1) The maximum shear stress must not exceed Tallow = 9 ksi. (2) In order to prevent binding or interference in the attached machin- ery, the angle of twist of gear B with respect to gear D must not exceed 1°. 1.25 ft 1.0 ft 3 hp 1.5 ft 1 hp 0.5 hp 1.5 hp

Problem : A train of spur gears with 20°full-depth involute teeth is shown in the Figure below. Gear 1 is the driving gear and transmits 50 kW power at 300 rpm to the gear train. The number of teeth on gears 1, 2, 3 and 4 are 30, 60, 25 and 50 respectively, while the module for all gears is 8 mm. Gears 2 and 3 are mounted on the same shaft. Gear 1 is rotating in the clockwise direction when seen from the left side of the page. The shaft is made of plain carbon steel 40C8 (Syt = 380 N/mm2) and the factor of safety is 2. Using maximum shear stress theory, estimate suitable diameter of shaft. 150 500 125 3 B1 B2

The design of the gear-and-shaft system shown in Figure Q3 requires that steel shafts of the same diameter be used for both AB and CD. It is further required that τmax ≤ 60MPa and that the angle ∅0 through which end D of shaft CD rotates not exceed 1.5°. Knowing that modulus of rigidity(G) is equal to 77GPa, determine the required diameter of the shafts
