  • Rotating Cylinder

Rotating cylinder is an actuator that converts hydraulic energy into mechanical rotational motion, and is widely used in industrial fields where limited angle rotation is required. The following is a detailed introduction to the rotating cylinder:

1. Working principle of rotating oil cylinder

The rotating oil cylinder pushes the piston to move linearly through hydraulic oil, and then converts the linear motion of the piston into rotary motion through the internal multiple spiral gear mechanism or rack mechanism, thereby driving the load to rotate.

Hydraulic drive: Hydraulic oil enters the cylinder and pushes the piston to move.

Movement conversion: The linear motion of the piston is converted into a rotary motion through the gear mechanism.

Angle control: By controlling the flow rate and direction of hydraulic oil, the rotation angle can be accurately controlled.

2. Characteristics of rotating oil cylinder

Compact structure: small size and light weight, suitable for occasions with limited installation space.

High torque output: Large rotational torque can be generated in a limited space.

High precision control: The rotation angle can be accurately controlled and the repeat positioning accuracy is high.

High reliability: Use high-strength materials and sealing technology to adapt to harsh working conditions.

Various rotation angles: can achieve rotation angles of 90°, 180°, 270°, 360° or even greater, up to 1500°.

High protection level: The internal structure is dust-proof, pollution-proof, moisture-proof, and adapts to harsh environments.

3. Application fields of rotating oil cylinder

Rotating cylinders are widely used in industrial fields that require limited angle rotation, including but not limited to:

Construction machinery: such as excavators, loaders, cranes, etc., used to drive the rotation of the working device.

Metallurgical equipment: such as rolling mills, shearing machines, etc., used to drive the rotation of rolling rolls or nip devices.

Port machinery: such as cranes, loading and unloading machines, etc., used to drive the rotation of the boom or slewing platform.

Mining machinery: such as drilling rigs, boring machines, etc., used to drive the rotation of drill bits or cutting devices.

Automobile industry: such as welding robots, assembly lines, etc., used to drive the rotation of robotic arms or fixtures.

Food processing: such as packaging machines, filling machines, etc., used to drive the rotation of conveyor belts or sorting devices.

Medical equipment: such as surgical robots, rehabilitation equipment, etc., used to drive the rotation of surgical instruments or rehabilitation devices.

4. Key points for selecting rotating oil cylinders

Torque requirement: Choose the right torque according to the load size and rotation speed.

Rotation angle: Choose the appropriate rotation angle range according to application requirements.

Working pressure: Select the appropriate cylinder working pressure according to the system pressure.

Installation space: Select the appropriate cylinder size and installation method according to the installation position.

Environmental conditions: Select the appropriate protection level and sealing material according to the working environment.

Accuracy requirements: Select the appropriate rotation accuracy and repeat positioning accuracy according to application requirements.

5. Maintenance and maintenance of rotating oil cylinders

Regular inspection: Check the sealing performance of the oil cylinder, the cleanliness of the hydraulic oil and the tightening of the connecting parts.

Hydraulic oil replacement: Replace hydraulic oil regularly to prevent oil contamination and wear of the oil cylinder.

Cleaning and maintenance: Keep the surface of the oil cylinder clean to prevent dust and debris from entering the inside of the oil cylinder.

Avoid overload: Avoid the oil cylinder working under overload condition and prevent damage to internal parts.

Professional maintenance: If abnormalities are found in the oil cylinder, contact professionals for repair in time.
