Description

Technical Field

[0001] The utility model relates to the technical field of hollow rotating platforms, in particular to a gear type hollow rotating platform. Background Art

[0002] Hollow rotating platform is a kind of equipment used to rotate and turn objects. Its characteristic is that the middle part is hollow and can accommodate larger objects. Gear type hollow rotating platform is widely used in industrial automation, mechanical processing, laboratory research and other fields. It can be used to rotate large or heavy objects to improve work efficiency and precision. At the same time, the gear transmission system has high transmission efficiency and durability, and can operate stably for a long time.

[0003] For example, a hollow rotating platform with zero backlash and high rigidity is disclosed as CN113202919A, which includes a shell, a shaft seat, an active component and a driven component. One end of the shaft seat is connected to the shell, and the shaft seat is provided with an axial hole along the axial direction. The axial hole is eccentrically arranged with the shaft seat. The active component includes a bracket and a transmission member. The bracket is rotatably connected to the shaft seat. One end of the bracket is connected to the transmission member, and the other end is provided with an axial hole. The bracket and the axial hole are coaxially arranged, and the transmission member and the bracket are coaxially arranged. The transmission member is built into the shell. The driven component includes a driven member, which is rotatably connected to the shell, and the driven member is meshed with the transmission member. This hollow rotating platform with zero backlash and high rigidity has the characteristics of simple structure and high transmission accuracy. The transmission member and the shaft seat are eccentrically arranged, and the central axis of the transmission member is parallel to the central axis of the shaft seat but does not overlap. There is an eccentricity. By slightly adjusting the position of the shaft seat, the center distance between the transmission member and the driven member is changed, and the transmission gap is adjusted to achieve zero backlash transmission.

[0004] The above-mentioned hollow rotating platform with zero transmission backlash and high rigidity can adjust the transmission gap by meshing the driven part with the transmission part. However, when the central control rotating platform is used for rotation, the platform and the center axis are in contact for a long time. When the platform rotates, there is wear between the platform and the axis. After a long period of use, it is easy to cause wear of the platform and reduce the service life of the device.
