The common forms of motion of the executive member are rotary motion, linear motion, curve motion and reciprocating motion. In the automatic door project, the door body is the executive member, and the basic motion form of the door body is rotary and linear motion.

 

The common forms of motion of the executive member are rotary motion, linear motion, curve motion and reciprocating motion. In the automatic door engineering, the door body is the executive member, and the basic motion form of the door body is rotary and linear motion.
Rotary motion can be divided into three types
Continuous rotary motion, intermittent rotary motion and reciprocating swing. The automatic door revolving door is a continuous rotary movement, and its motion parameter is the speed per minute. The arc-shaped automatic door is a reciprocating swing, and its motion parameters are the number of swings per minute, the size of the swing angle and the speed ratio coefficient of the stroke.
Linear motion can also be subdivided into three
Reciprocating linear motion, reciprocating linear motion with rest and unidirectional linear motion with rest. The smooth automatic door and the telescopic courtyard automatic door in the automatic door are reciprocating linear motion with a stop. Its motion parameters are the number of stops, the position of the stop, the length of the stop, the size of the stroke and the working speed in a working cycle.
The door body of the automatic door generally has no curve movement and compound movement form. The coordination of the automatic door execution component and the motor After the motion parameters of the execution component (door body) and the motor are determined, the total transmission ratio of the kinematic chain can be calculated. The original motion parameters of the door body and the total transmission ratio of the kinematic chain are the necessary data for the next selection of the mechanism and the design of the transmission system.
