Hollow Rotary Reducers
Characteristic:
- High load
- High stiffness
- Digital control
- Multi-points positioning
- High positioning accuracy
- Arbitrary configuration of motor
How does hollow rotary actuator work?
- The hollow rotary actuator is driven by motor to realize automatic angle adjustment.
- Angle adjustment unlimited.
- Precision shafting design, ensure precision high, large load;
- Servo motor or Stepper motor are connected through high-quality couplings to eliminate space and machining position errors.
How accurate are hollow rotary actuator?
- Accurate data: hollow rotary actuators are sized in 60, 85, 110, 135, 200.
- The surface is through high and middle heat treatment which the grinding precision can be ISO6 and surface hardness HRC 65.
- Also the repetitive accuracy up to ±10 arcsec and concentricity&flatness ±0.05 mm.
What is the advantage of a hollow rotary actuator?
- High efficiency
- Efficiency exceeds 98%
- Large-Diameter, Hollow Output Table Makes Simple Wiring and Piping Possible
- High Power and Rigidity
- Direct Coupling for Higher Reliability
- Bottom and Workbench Contact, except the four screw holes, the center ring directly below the bearing also contacts the worktable.
- There are steel rings at the bottom, and the load is borne by steel parts, in case the bearing presses the aluminium structure to deform clearance.
- An integrated design of gear and cross roller bearings is under developing, it can improve rotation accuracy and stability.
What is a Hollow Rotary Reducers used for?
Now the hollow rotary actuator is applied in different industries especially in the 3C industry like the grinding machine of mobile phone shells, also visual testing equipment, Laser equipment industry, Semi-conduct equipment industry, also highly matched with the linear module for some applications, etc. It can be used for applications in which accurate positioning and heavy load tolerance capacity is a must.
What is the difference between linear actuator and rotary actuator?
A linear module moves in a straight line, usually in a back and forth motion. In contrast, a hollow rotary actuator moves along a circle at a specific Angle with reference to the midpoint of the circle, enabling 360 degrees of multi-point positioning.
