Hollow Rotary Gear Box Hollow Rotary Speed Reducer For Surgical Robots
Hollow Shaft Rotary Platform Features:
1. Hollow structure
The turntable of the hollow rotating platform is a hollow structure, and the servo motor is connected to the side, which is convenient for the installation of air pipes and wires in the tool.
2. High rigidity
The turntable of the hollow rotating platform is supported by a set of precision crossed roller bearings. The rollers in the bearing are arranged in a 90-degree staggered arrangement, and the diameter of the rollers is slightly larger than the size of the raceway between the inner ring and the outer ring of the bearing, which makes the crossed roller bearing There is a pre-tightening force between the inner and outer rings and the rollers, so the servo rotating platform turntable supported by the bearing can bear various moments such as radial, axial and overturning, and its rigidity is more than 5 times that of traditional bearings.
3. High rotation accuracy
After the SR series servo rotary table is assembled, the cross roller bearing of the table is used as the rotation center, and the outer diameter and end face of the turntable are ground again (standard level is fine turning) to ensure the coaxiality and parallelism of the turntable, etc. Geometric tolerance.
