Embodiment 1
[0022] figure 1 It is a structural schematic diagram of a threaded roller planetary bearing provided by the present invention. Such as figure 1 As shown, the threaded roller planetary bearing provided in this embodiment includes a bearing inner ring 1, a first wire retaining ring 2, a first planet carrier 3, a bearing outer ring 4, rollers 5, a second planet carrier 6, and a second steel wire retaining ring7. Both ends of the outer wall of the bearing inner ring 1 are provided with optical axis steps, and threads with a helix angle of zero are arranged between the optical axis steps at both ends. The thread groove roller planetary bearing provided by this embodiment can bear both radial load and axial load, and can also bear radial load and axial load at the same time. Compared with the thread groove roller planetary bearing of the same size and specification , The load of the thread groove roller planetary bearing provided by this embodiment is more than three times that o...
