1.What is a hollow rotary actuator
A hollow rotary actuator is a component that realizes control through rotational motion. Its structure includes a control element, a shaft, a drive mechanism and a housing. The housing is mostly made of aluminum alloy or stainless steel. The shaft is supported by a high-precision bearing, and the control element realizes the rotational motion through a drive mechanism. Due to its hollow design, fluid or signal can be transmitted at the center of the shaft.
2.Working principle of hollow rotary actuator
The hollow rotary actuator drives the shaft to rotate through a drive mechanism such as an electric motor, and the control element realizes rotational motion through a structure connecting the shaft. The rotation speed and angle of the control element can be precisely controlled by electronic devices such as sensors and controllers. This design gives the actuator a unique advantage in situations where fluid or signal transmission is required at the same time.
3.Design features of hollow rotary actuators
1.High precision: The hollow rotary platform adopts a precise gear transmission and bearing system to ensure rotation accuracy and repeatable positioning accuracy, which can usually reach ±30 seconds or even higher. Some designs can even achieve micron-level rotation accuracy to meet high-precision application requirements.
2.High rigidity: The platform structure has been optimized and designed to have high rigidity and stability and can withstand large loads. For example, the design of the cross roller bearing enables the platform to withstand various moments such as radial, axial, and overturning, and its rigidity is more than 10 times that of traditional bearings.
3.Hollow design: The center of the hollow rotating platform is a hollow structure, allowing other equipment and pipelines to pass through, greatly simplifying system design and installation. This design not only simplifies the installation process, but also improves the flexibility of the equipment.
4.Multiple installation methods: Supports multiple installation methods such as horizontal and vertical to adapt to different application scenarios.
5.Modular design: The modular design allows users to choose different configurations and functions according to their needs, and it is also convenient for maintenance and replacement of parts.
6.High reliability: After strict quality control and testing, it ensures long-term reliability. In addition, low-friction materials and optimized design ensure low noise during operation.
7.High load capacity: The hollow rotating platform can withstand large loads and ensure stable operation of the platform.
4.Application places of hollow rotary actuators
