Rodless cylinder

Working principle of rodless cylinder_Mechanical rodless cylinder structure diagram, price, model and manufacturer introduction are as follows:
The working principle of the rodless cylinder is the same as that of the ordinary cylinder, except that the external connection and sealing forms are different.

Both sides of the rodless cylinder are hollow. The permanent magnet inside the piston rod drives another magnet (moving part) outside the piston rod. What I want to say is that it has very high requirements for cleanliness. Our company's magnetic couple is rodless. The cylinder often needs to be removed and cleaned with gasoline, which may be related to its working environment. .

There is a piston in the rodless cylinder, but there is no piston rod. The piston is installed in the guide rail, the external load is connected to the piston, and the actuation depends on the air intake.

The movement of the magnetic couple is achieved by using the permanent magnet in the hollow piston rod to drive the movement of another magnet outside the piston rod. Because the inner and outer magnetic rings are easy to separate when the speed is fast and the load is high, it is less used now. The size of its load mass requires finding the characteristic curve of its mass and speed. Nowadays, mechanical ones are used more often.

Rodless cylinders are divided into magnetic couple rodless cylinders and mechanical contact rodless cylinders. A rodless cylinder refers to a cylinder that uses a piston to directly or indirectly connect to an externally executed machine, and allows it to follow the piston to achieve reciprocating motion. The biggest advantage of this type of cylinder is that it saves installation space.

Magnetic couple rodless cylinder:
The piston drives the moving body outside the cylinder to move synchronously through magnetic force. Its working principle: A set of high-strength permanent magnetic rings is installed on the piston. The magnetic lines pass through the thin-walled cylinder and interact with another set of magnetic rings set outside. Since the two sets of magnetic rings have opposite magnetic properties, they have strong suction. When the piston is pushed by air pressure in the cylinder, it drives the magnetic ring sleeve outside the cylinder to move together under the action of magnetic force. The thrust of the cylinder piston must match the suction force of the magnetic ring.

Mechanical contact rodless cylinder:
There is a groove in the axial direction of the cylinder tube, and the piston and Shangzhi move in the upper part of the groove. In order to prevent leakage and dustproof requirements, stainless steel sealing tapes and dustproof stainless steel tapes are used at the opening to be fixed on the cylinder heads at both ends. The piston frame passes through the groove to connect the piston and Shangzhi as a whole. The piston is connected to the Shangzhi and drives the actuator fixed on the Shangzhi to achieve reciprocating motion.

Rodless cylinder features:
1. Compared with ordinary cylinders, the installation device can be reduced by 1/2 under the same stroke;
2. No need to install anti-rotation machinery;
3. Suitable for cylinder diameter 10-80mm, maximum stroke up to 41.5m;
4. Speed ​​10m/s

The ancestor of the rodless cylinder is the German Origa Pneumatic Equipment Co., Ltd. The concept of rodless cylinders was first proposed and practiced by Origa. Origa opened the door to the rodless era with its advanced technology research and development capabilities. Rodless cylinder saves space for equipment integration. A rodless cylinder refers to a cylinder that uses a piston to directly or indirectly connect to an external actuator, and allows it to follow the piston to achieve reciprocating motion. The biggest advantage of this type of cylinder is that it saves installation space. Rodless cylinders are divided into magnetic couple rodless cylinders, magnetic cylinders and mechanical rodless cylinders.
