Knowing the center distance and the multiple of the two gears, the modulus and the number of teeth of the two gears (center distance 157.5) are 1.5 times the speed of the pinion
You have the condition that "the big gear is 1.5 times as fast as the pinion."". In fact, it should be that the pinion is 1.5 times as large as the big one
Among them, a is center distance, Z1 is small gear tooth number, Z2 is big gear tooth number, and M is modulusThat is, 157.5=2.5z1m/2, z1m=126, you need to ask Z1 and Z2 integer solutions, there are several sets of answers, so you give the conditions are not the most likely is the following two groupsZ1=126, z2=189, m=1, and z1=252 z2=378 m=0.5
The speed of the big gear can not be 1.5 times that of the pinion, but it should be oppositeFor standard spur gears, the center distance is a= (z1+z2) m/2
