We mainly introduced the main characteristics of all kinds of rack
(1) due to the rack tooth profile of straight line, so that each point on the tooth profile with the same pressure Angle, and is equal to the tooth profile Angle, this Angle is called tooth profile Angle, standard for 20 °.
(2) and tooth top line on any straight line parallel with the same pitch and modulus.
(3) with the top line parallel and tooth thickness is equal to the tooth groove width of line known as the dividing line (line), it is to calculate baseline of rack size.
The characteristics of the horizontal gear rack piston actuators:
(1) it is easy to design into the double piston, make double its output torque; On the other hand, when a certain output torque, can obtain more small size of the actuator, reduce weight and get big size; (2) uniform rotation gear and rack, ?
