The hydraulic rotary actuator in the CY2 series is engineered for high performance, offering a reliable solution for converting linear piston motion into robust flange rotation. Its sophisticated design ensures smooth operation and durability in demanding applications. Below, we delve into the structure, operational features, and maintenance tools for these advanced actuators.
Each CY2 hydraulic rotary actuator incorporates:
1. Integrated Gear Ring: A stationary component fused with the housing.
2. Central Shaft with Mounting Flange: Equipped with integral bearings, this shaft supports radial and axial loads effectively.
3. Annular Piston Sleeve: Facilitates the actuator’s combined linear and rotational motion.
Helical Splines and Dual Rotation
· The shaft’s helical splines interlock with the piston sleeve’s inner grooves, while its outer grooves engage with the stationary gear ring.
· Hydraulic pressure moves the piston axially, inducing simultaneous rotation of both the sleeve and shaft. Thanks to the dual-helical spline design, the shaft achieves twice the rotational movement of the piston.
Locking and Positional Stability
· A counterbalance valve traps hydraulic fluid inside, locking the shaft in position and preventing unintentional movement.
Many models in the CY2 series come with a factory-installed counterbalance valve. This valve provides:
· Overload Protection: Shields the actuator from excessive loads.
· Positional Locking: Prevents position drift, ensuring stability under external forces.
· Hydraulic Shock Reduction: Mitigates backlash during operation.
· Controlled Rotation Speed: Ensures smooth operation even under eccentric loads.
Maintaining a hydraulic rotary actuator requires specialized tools for disassembly and reassembly. Here's a comprehensive list of essentials:
1. Pipe Clamp: Secures the actuator for repair.
2. Hex Wrench: For removing screws and port plugs.
3. Safety Goggles: Ensures operator protection.
4. Rubber Mallet: Assists in removing or assembling shafts and sleeves.
5. Flashlight: Enhances visibility for fault inspection and timing alignment.
6. Rear End Cap Assembly Tool: Tailored for CY2 actuators with original Chiyu seal kits.
7. Permanent Marker: Marks timing points and areas requiring repair.
8. T-Type Screwdriver: Facilitates precision tasks.
9. Seal Tool: For safely handling seals and wear rings.
10. Punch Tool and Cylindrical Pin: Aids in end cap removal and installation.
For efficient seal replacement, a modified flat-head screwdriver can be transformed into a seal tool:
1. Heat the Screwdriver Tip: Use a flame until the tip glows red.
2. Bend Slightly: Shape the heated tip into a smaller radius.
3. Smooth Edges: File down sharp edges to prevent seal damage.
The CY2 hydraulic rotary actuator is a versatile and efficient component for various industrial applications. Proper maintenance, supported by the right tools and techniques, ensures long-term reliability and optimal performance.
