Hypoid Gear Hollow Rotary Platforms are a specially designed precision rotary platform, characterized by the use of Hypoid Gear transmission and a hollow structure, suitable for high torque, low backlash, and high rigidity precision rotary motion requirements.
Hypoid Gear Hollow Rotary Platforms, also known as hypoid gear hollow rotating tables, are precision rotating equipment that integrate a right angle gearbox and hypoid gears, commonly used in the field of industrial automation.
What are the Core Features of Hypoid Gear Hollow Rotary Platform?
1).Hypoid Gear Transmission
High torque transmission: The helical tooth design of Hypoid gears allows them to withstand greater torque than ordinary worm gears or planetary gears while maintaining smooth operation.
Low backlash (<1 arcmin): The precision ground Hypoid gear pair can significantly reduce transmission clearance, improve positioning accuracy, and is suitable for high dynamic applications.
High efficiency (>90%): Compared to worm gears (efficiency usually<50%), Hypoid gears have smaller friction losses and are suitable for long-term operation.
Non intersecting axis transmission: The motor can be offset installed, saving space and optimizing equipment layout.
Gear design: Adopting hypoid gears, the axes of the input shaft and output shaft do not intersect, and the gear teeth are in the shape of a spiral or spiral cone. This unique gear geometry allows the rotating platform to achieve a compact, low profile design while ensuring smooth and quiet operation.
2).Hollow structure: The turntable of the platform is a hollow structure with a through hole in the middle. This allows cables, hoses, or other components to pass through the center of rotation, providing convenience for integrated systems and automation equipment, facilitating the installation of gas pipes, wires, etc. in molds, and reducing mechanical interference.
3).Key features: It has high torque capacity, can transmit large torque in a compact size, can withstand large radial and axial loads, and can also withstand instantaneous impact loads; Having precise angular positioning and good repeatability accuracy, the rotation accuracy can usually reach the level of arcseconds; Smooth operation, small return gap, capable of achieving low backlight rotation; Sturdy structure, suitable for industrial environments, high reliability, and long service life.
4).Modular design
Can integrate servo motors, encoders, brakes, and other components, supporting EtherCAT/CANopen communication.
Some models support absolute encoders, which do not require resetting after power failure.
