What are the advantages of hollow right angle reducer?

2021-11-08

The hollow right-angle reducer is used in many rotating occasions. It can replace DD MOTOR and cam divider. It is a revolutionary product of rotary motion mechanism. The two are balanced, the repeat positioning accuracy is less than 5 seconds, the motor is easy to prepare, the load is stable, and it can be matched with AC Servo motor or stepper motor can be divided at any angle, which not only satisfies the digital control that cannot be achieved by the divider, but also has the positioning accuracy comparable to that of the DD motor.

1. Hollow structure

The turntable of the hollow right-angle reducer is a hollow structure, and the servo motor is connected to the side, which is convenient for the installation of air ducts and wires in the smelting tool.

2. High repeat positioning accuracy

The hollow right-angle reducer adopts a single-stage helical gear to increase the output torque, and the gear accuracy grade is below grade 5. In addition, the flexible backlash adjustment mechanism controls the backlash by changing the center distance between the two gears, so that the backlash of the hollow rotating platform can be adjusted. Smaller, repeatable positioning accuracy below 5 arc seconds.

3. High rigidity

The turntable of the hollow right-angle reducer is supported by a set of precision cross roller bearings. The rollers in the bearing are staggered at 90 degrees. The diameter of the rollers is slightly larger than the size of the raceway between the inner and outer rings of the bearing, so that the cross rollers There is a pre-tightening force between the inner ring and the outer ring of the sub-bearing, and the servo turntable supported by the bearing can bear various moments such as radial, axial, and overturning, and its rigidity is more than 10 times that of traditional bearings.

4. High rotation accuracy

After the hollow right-angle reducer is assembled, take the cross roller bearing of the platform as the rotation center (the standard grade is fine turning), and re-grind the outer diameter and end face of the turntable to ensure the coaxiality, parallelism and other geometric tolerances of the turntable.

5. Arbitrary configuration of the motor

The hollow right-angle reducer can flexibly change the interface size by customizing the flange and input shaft hole, and is suitable for connecting any brand of servo motor.

The hollow right-angle reducer is driven by a motor to realize the automation of angle adjustment. Precision machining worm gear or gear drive, infinite angle adjustment. Precise shaft system design to ensure high precision and large load; stepper motor and transmission part adopt imported high-quality elastic coupling Connect, eliminate space and processing shape and position errors. The scale of the outer ring of the turntable is intuitive; the standard interface is convenient for signal transmission; the manual wheel configuration can be electronically controlled and manual.
