Rodless Cylinder is a component used to achieve linear motion and do work. Its structure and shape have various forms, and there are many classification methods. The following are commonly used.
① According to the direction of compressed air acting on the piston end face, it can be divided into single-acting cylinder and double-acting cylinder. The single-acting cylinder has only one direction of movement, which is driven by air pressure, and the piston is reset by spring force or gravity; the double-acting cylinder piston is all completed by compressed air.
② According to the structural characteristics, it can be divided into piston cylinder, blade cylinder, film cylinder, gas-liquid damping cylinder, etc.
③ According to the installation method, it can be divided into ear seat cylinder, flange cylinder, shaft pin cylinder and flange cylinder.
④ According to the function of the cylinder, it can be divided into ordinary cylinder and special cylinder. Ordinary cylinders mainly refer to piston single-acting cylinders and double-acting cylinders; special cylinders include gas-liquid damping cylinders, film cylinders, impact cylinders, booster cylinders, stepping cylinders, rotary cylinders, etc.
Cylinders that perform reciprocating linear motion can be divided into four types: single-acting cylinders, double-acting cylinders, diaphragm cylinders, and impact cylinders.
① Single-acting cylinder: There is a piston rod at only one end. The air is supplied from one side of the piston to generate air pressure. The air pressure pushes the piston to generate thrust and extend, and returns by spring or self-weight.
② Double-acting cylinder: Air is supplied alternately from both sides of the piston, and force is output in one or two directions.
③ Diaphragm cylinder: A diaphragm is used instead of a piston, and force is output in only one direction, and a spring is used to reset. It has good sealing performance, but a short stroke.
④ Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of the piston's high-speed (10-20 m/s) movement to do work.
⑤ Rodless cylinder: A general term for cylinders without piston rods. There are two major categories: magnetic cylinders and cable cylinders.
The cylinder that does reciprocating swing is called a swing cylinder. The inner cavity is divided into two by the blades, and the air is supplied to the two cavities alternately. The output shaft does swing motion, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-liquid damping cylinders and stepping cylinders.
