Involumetry
it is intended to reduce the velocity from 1800 rpm in a one step transmission using two gears of standard involute with a pressure angle of operation of 20°. If the pinion has 18 teeth determin the minimum possible velocity of the shaft of the gear without causing interference considering a maximum velociy ratio of 1/4. Consider gears of step 6

A step down gear drive is used in a conveyor system. The input pinion is made of 18 teeth runs at 1720 rpm, the driven gear runs at 860 rpm. The gears are supported on less rigid mountings, less accurate gears. The gears are made by hobbing process. Find: (a) The tooth bending strength of both wheels and the maximum power that can be transmitted to the drive (b) By considering surface durability conditions find the_maximum power that can be...

1. The countershaft shown in the Fig QI has two spur gears mounted on it with teeth cut with a 20 pressure angle. The shaft (grooved) is to be made of cold-drawn AISI 1040 steel having Sut= 779 MPa and S,-593 MPa, an elongation of 19% and HB-262. You are asked to size the shaft for safe operation according to DE-Eilliptic criterion by using a factor of safety of 2.5 and a reliability of 99 percent. The stress-concentration factors for...
