3. A commercial enclosed gear drive consists of a 20 spur pinion having 16 teeth driving a 48-tooth gear. The pinion speed is 300 rev/min, the gear face width 2 in., and the diametral pitch 6 teeth/in. The gears are grade t steel, through-hardened at 200 Brinell, made to No. 6 quality standards, uncrowned, and are to be accurately and ngid mounted Assume a lion life ofi will transmitareliability of90%(KR 0.85), and use YN 1.355N 01:8 and Z 1. used...
See Figure P12-1. The shaft rotating at 550 rpm carries a spur gear B having 96 teeth with a diametral pitch of 6. The teeth are of the 20%, full-depth, involute form. The gear receives 30 hp from a pinion directly above it. Compute the torque delivered to the shaft and the tangential and radial forces exerted on the shaft by the gear.

The accessory drive unit of a large aircraft engine involves an identical pair of 200 full-depth spur gears. The gears have 70 teeth and rotate together at 8000 rpm. The diametral pitch is 12 and the face width 1.0 in. The gears are made of alloy steel, case-hardened to 62RC (680 Bhn). Although the case extends throughout the fillet, it is conservatively decided to use the core hardness of 500 Bhn for calculating fatigue strengths. The tooth profiles are finished...
27 Two 20° straight bevel gears have a diametral pitch of 4, and 24 and 48 teeth, respectively The tooth face width is 2 in. The pinion rotates at 1000 rev/min and transmits 50 hp. The shafts are at 90. Determine the components of the gear tooth force and show these on a sketch of the ge 27 Two 20° straight bevel gears have a diametral pitch of 4, and 24 and 48 teeth, respectively The tooth face width is...
(1) A pair of meshing spur gears having 20 degree full depth teeth and face widths of 2.5-in, a diametral pitch of 4 and both made of steel having a BHN of 400. The pinion is rotating at 600 pm, has 30 teeth and the velocity ratio is 2/3. Assume uniform power source with moderate shock, less rigid mounting with contact across the full face. Find the maximum horsepower that can be transmitted based on strength using the AGMA method....

The figure above shows two spur gears mounted on a shaft at A and C. This shaft gear assembly is supported on two pedestal bearings at D and Brespectively. These bearing supports act as simple supports. Neglect the weight of the shaft and the gears. The force on gear 1 is shown at an angle with respect to the vertical "y" axis and the force on gear 2 (Fc-1000 N) is shown at an angle with respect to the horizontal...
2. Fig.2 shows an epicyclic gear train in which the internal teeth on the gears A and B have the same diametral pitch. Gear A has 88 teeth and gear B has 100 teeth both internally and externally. The sun-wheel C which is keyed to shaft P has 44 teeth and the pinion E keyed to shaft R has 25. There are floating compound planet wheels F, G. The power input to shaft R is 8 kW at 1440 rev/min....
Question is in Metric not imperial MEA35TA/101/0/2019 Question 9 An uncrowned straight-bevel pinion has 30 teeth, a diametral pitch of 6, and a transmission accuracy number of 6. The driven gear has 60 teeth. Both are made of No. 30 cast iron. The shaft angle is 90 . The face width is 1.25 in, the pinion speed is 900 rev/min, and the normal pressure angle is 20.. The pinion is mounted outboard of its bearings: the bearings of the gear...
