Example Embodiment
[0037] Example 1
[0038] Combine Figure 1-3 , Figure 5-6 As shown, this embodiment provides a damping joint for a master manipulator, including: a first link 1; a second link 4, the second link 4 is rotatably connected with the first link 1; a rotating shaft assembly, The rotating shaft assembly includes a key shaft 5 and a bearing 9. The key shaft 5 penetrates the first connecting rod 1 and the second connecting rod 4 and is locked and fixed in the axial direction, and the key shaft 5 includes a fixedly connected spline section 51 and a cylindrical section 52 The spline section 51 is connected with the second connecting rod 4 by key, the cylindrical section 52 is connected with the first connecting rod 1 through the bearing 9; the damping assembly, the damping assembly includes the first rotary damping 11, the first rotary damping 11 is sleeved on the key shaft On the cylindrical section 52 of 5, the first rotation damper 11 includes a housing 112 and a rotating body 111. The...

[0048] Example 2
[0049] Combine Figure 1-2 , Figure 4 As mentioned, the difference between this embodiment and the foregoing embodiment is that the damping assembly further includes a first gear 2, a second gear 8, and a second rotation damper 3. The first gear 2 and the second gear 8 mesh with each other, and the second rotation damper 3 includes a relatively rotatable housing 32 and a rotating shaft 31, the housing 32 is fixed to the first connecting rod 1, the first gear 2 and the second gear 8 are respectively keyed to the rotating shaft 31 and the spline segment 51; the second gear 8 is keyed by the shaft 5 rotates in linkage and transmits the rotation to the first gear 2. The first gear 2 drives the rotation shaft 31 to rotate, and the rotation shaft 31 and the housing 32 rotate relative to each other to generate braking torque.
[0050] The second rotary damper 3 has the same working principle as the first rotary damper 11. It also has a housing 32 in which damping grea...
Example Embodiment
[0055] Example 3
[0056] The difference between this embodiment and the above-mentioned embodiment is that the number of the first rotary damper 11 and the special-shaped axle clamps 12 is multiple, and the plurality of special-shaped axle clamps 12 and the first rotary damper 11 are sequentially arranged in the bearing chamber of the first connecting rod 1. To adjust the torque value of the damping joint.
[0057] As in figure 2 One or more groups of special-shaped shaft clamps 12 and first rotary dampers 11 are then passed under the first rotary dampers 11 to realize the series connection of multiple first rotary dampers 11, and the damping of the main manipulator joint can be further adjusted.
[0058] Preferably, the number of the second rotary dampers 3 is multiple, and the multiple second rotary dampers 3 are distributed on the first connecting rod 1 at intervals, and are meshed in series through a plurality of first gears 2 to adjust the torque of the damping joint value. ...
