Question:

How about the center distance between the rack and the gear?

How about the center distance between the rack and the gear?For example, the rack and pinion modulus is 4, the gear tooth number is 20, the gearHow far is the center distance from the top or the bottom of the bar?

Answer:

[4]: calculate the distance between the center of the ruler and the root of the rulerDistance = pitch circle radius + modulus *1.25= 40 + 4*1.25= 45Feel shy ^ ^, careless with yesterday, the formula is wrong! Quickly change correctly, let everyone jokes.
[2]: because of the standard installation, the reference circle coincides with the circleCalculate the circle radius = 80/2=40[3]: calculate the distance between the top teeth of the distance gaugeDistance = pitch circle radius modulus *1.0= 40-4*1= 36
Conditions: cylindrical straight teeth, standard teeth, standard installation[1]: calculate the diameter of gear indexing circle4*20=80
