1) A pinion in mesh with a gear. The pinion is rotating a 550 RPM with an input power of 15 HP. The pinion has 18 teeth and diameter pitch of 4. The gear has 42 teeth. A square key is to be used, find: a) the pitch diameter of the pinion. b) the pitch diameter of the gear. c) the output torque of the gear. d) the minimum length of the key used to attach the gear?
2) A 5v belt drive system operates an input speed of 1250 RPM at the small sheave. The driving sheave has a pitch diameter of 6.000 in, and the driven sheave has a pitch diameter of 19.000 in. If an optimum center distance of 47 in is specified. Calculate: a) the output speed of the driven sheave. b) the length of belt required. c) select an appropriate standrad belt from the table based on the calculated length. d) recalculate the actual distanced required for the standrad length belt ?
3) A single standrad number number 0.40 chain and sprocket system is designed with an input speed of 700 RPM and an input power of 6.325 HP. Asume a service factor of 1.2 to determine the designe power. An output speed of 175 RPMis specified. Determine: a) number of teeth on the small sprocket, b) number of teeth on the large sprocket, c) lubrication type required, d) the required length of chain (in inches) if the center distance is 20.5 in
4) for the gear train to the right, an input power of 0.75 HP is delivered at 1550 RPM, calculate: a) the overall train value. b) the output rational speed at shaft 5. c) the output torque at shaft 5. Relevant gear data is= NA= 17, NB= 36, NC= 19, ND= 41, worm E = double lead, worm G = triple lead, NH= 37?
