Description

1.Product characteristics

Hollow rotating platform is a kind of mechanical spare parts used in many kinds of rotating motion. It adopts single-stage helical gear deceleration mode to increase the output torque. By changing the center of the gear to control the backlash, the accuracy is less than 5 arc seconds, and the 90-degree staggered roller bearings can withstand large radial and axial overturning torques. The hollow rotating platform uses high precision gear structure and radial bearing. Torque, rigidity and bearing effect are good. It can be divided at any angle with stepping and servo. It satisfies the fixed number control of the divider. The positioning accuracy is higher than that of the divider. It is widely used in some light-load and high-speed transmission industries.
