As an important part of gear transmission, I believe you are not unfamiliar with it. What are the characteristics of the usually used rack? What is its working principle? This time, the manufacturer will answer for you!
Main characteristics of rack
(1) Since the rack profile is a straight line, each point on the profile has the same pressure angle and is equal to the inclination angle of the profile. This angle is called the tooth profile angle, and the standard value is 20 °.
(2) Any straight line parallel to the tooth top line has the same pitch and modulus.
(3) The straight line parallel to the tooth top line and the tooth thickness is equal to the tooth slot width is called the dividing line (center line), which is the datum line for calculating the size of the rack.
(4) Main parameters of rack: slot width / tooth top height / tooth root height / tooth height / tooth thickness / tooth root circle radius.
