Straight bevel gears are mainly used to change the change the rotation axis of intersecting shafts. You work as a maintenance engineer for a food packaging company and your supervisor asked you to accurately calculate the dimensions for a set of straight bevel gears used in one of the differential gearboxes at the facility. The gear type is an uncrowned straight-bevel pinion has 22 teeth, a module of 4.5 mm, and a transmission accuracy number of 5. The pinion and the gear are made of through-hardened steel, both having core and case hardnesses of 210 Brinell. The pinion drives the 24-tooth bevel gear. The shaft angle is 90°, the pinion speed is 1600 rev/min, the face width is 23 mm, and the normal pressure angle is 20°. Both gears have an outboard mounting. Find: a) The power rating based on AGMA pitting resistance if the life goal is 10° revolutions of the pinion at 0.98 reliability.

Q: Two involute gears having module 3 mm and pressure angle 20° mesh externally to give a velocity ratio of 3. For this mechanism, the pinion runs at 75 rpm and addendum is equal to one module.For these condetions compute: 1- The number of teeth on each gear so that interference is just avoided. 2- The length of path and arc of contact. 3- The number of pairs of teeth in contact. 4- The maximum value of sliding velocity. 5- If the transmitted power is 5 kW, what is the applied torque on pinion and wheel.
02/ The following data relate to a pair of 20° involute gears in mesh: Module 6 mm, Number of teeth on pinion = 17, Number of teeth on gear 49; Addenda on pinion and gear wheel = 1 module. Find 1. The mumber of pairs of teeth in contact ; 2. The angle turned through by the pinion and the gear wheel when one pair of teeth is in contact, and 3. The ratio of sliding to rolling motion when the tip of a tooth on the larger wheel (i) is just making contact, (i) is just leaving contact with its mating tooth, and (i) is at the pitch point.
Input shaft of the gear train shown below rotates at 1,500 RPM. The output shaft must rotate exactly at 100 RPM. Minimum number of teeth can not be less than 20 and the maximum number of teeth can not be more than 150. The speed of gear B must be exactly 500 RPM. What is the train value and its sign (negative or positive) ? Note: Your answer should be in the following format: TV= -123 or TV=+123 Input pinion A N= 20 teeth W = 1,500 rpm A B
