Question

According to AGMA standards, contact stress numbers of pitting resistance for different types of gear teeth are calculated differently. Please select the right formula for each type of gear teeth. Equation a: $s_c = C_p \sqrt{\frac{W_t K_a K_m K_v K_s K_c}{FD_p l}}$ Equation b: $s_c = C_p \sqrt{\frac{W_t K_a K_m K_v K_s C_c C_{xc}}{FD_p l}}$ For helical gears, equation b should be used. For bevel gears, equation b should be used. For helical gears, equation a should be used. For bevel gears, equation a should be used. For spur gears, equation a should be used. For spur gears, equation b should be used.

The gearbox is to be designed with a compound reverted gear train as a speed increaser. It is needed to minimize the overall gearbox size and avoid the interference problem in teeth. For this gearbox; a) Calculate appropriate teeth numbers to provide an exact 56:1 increase in speed. b) Calculate appropriate teeth numbers to provide an 56:1 (±3% tolerance) increase in speed. Given Data: k=1, pressure angle (ϕ)=25°

A pair of cast iron bevel gears connects two shafts at right angles. The pitch diameters of the pinion and gear are 80 mm and 100 mm respectively. The tooth profiles of the gears are of 14.5º composite form. The allowable stress for both the gears is 55 MPa. If the pinion transmits 2.75 kW at 1100 rpm, find the module and number of teeth on each gear from the standpoint of strength and check the design from the standpoint of wear. Take surface endurance limit as 630 MPa and modulus of elasticity for cast iron as 84 kN/mm^2.

00:01 Hello students in this question it is given that the gear ratio is 4 is to 1 and we know that the larger wheels will be having 4 times number of teeth of a smaller wheel.
00:27 So let's assume that the number of teeth on smaller wheel as n thus the number of teeth on a larger wheel can be written as 4 into n.
00:48 Now in the first part of the question we need to determine the least number of teeth that can be used on each wheel...
