[0025] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0026] like Figures 1 to 3 As shown, at least one embodiment provides a rotating base for a coating fixture, including: a base 1, a rotating assembly 2, a turntable 3, and a plurality of planetary gear assemblies 4.
[0027] Specifically, a fixed gear 11 is provided on the upper surface of the base 1.
[0028] Specifically, the rotating component 2 is disposed on the upper surface of the fixed gear 11.
[0029] Specifically, the turntable 3 is set on the upper surface of the rotating assembly 2, and the lower surface of the turntable 3 is connected to a motor, thereby achieving rotation by the drive of the motor; wherein, a clearance hole is provided at the shaft center of the fixed gear 11 for the drive shaft of the motor to pass through.
[0030] Specifically, several planetary gear assemblies 4 are rotatably mounted on the turntable 3 and their lower parts mesh with the fixed gear 11. The planetary gear assembly 4 includes: a planetary gear seat 41, a graphite ring 42, and a planetary gear shaft 43. The planetary gear seat 41 passes through the turntable 3 and is fixedly connected to the turntable 3. The planetary gear shaft 43 passes through the planetary gear seat 41 and is rotatably connected to the planetary gear seat 41. The graphite ring 42 is sleeved on the planetary gear shaft 43 and is located inside the planetary gear seat 41.
[0031] In this embodiment, the turntable 3 rotates by the drive of the motor, thereby driving the planetary gear assembly 4 to rotate while revolving around the sun; during the rotation of the planetary gear assembly 4, the planetary gear shaft 43 rotates relative to the planetary gear seat 41. At this time, the graphite ring 42 can continuously lubricate the planetary gear shaft 43 through friction, thereby greatly reducing the coefficient of friction and wear.
[0032] like Figure 4 As shown, in some embodiments, the planetary gear assembly 4 further includes: a thrust bearing 44; wherein the thrust bearing 44 is sleeved on the planetary gear shaft 43 and located inside the planetary gear seat 41; and a graphite ring 42 is located above the thrust bearing 44.
[0033] In this embodiment, the thrust bearing 44 serves to support the planetary gear shaft 43, with its inner ring connected to the planetary gear shaft 43 and its outer ring connected to the planetary gear seat 41.
[0034] like Figure 4 As shown, in some embodiments, a copper sleeve 46 is fitted onto the planetary gear shaft 43; wherein the copper sleeve 46 is located between the graphite ring 42 and the planetary gear shaft 43.
[0035] Specifically, the upper end of the planetary gear shaft 43 is provided with a flange; the upper end of the copper sleeve 46 abuts against the flange of the planetary gear shaft 43, and the lower end of the copper sleeve 46 abuts against the inner ring of the thrust bearing 44, that is, the planetary gear shaft 43, the copper sleeve 46 and the inner ring of the thrust bearing 44 rotate synchronously.
[0036] In this embodiment, the presence of the graphite ring 42 can serve as a radial limit to prevent the planetary gear shaft 43 from tilting or wobbling. Therefore, during the rotation of the planetary gear shaft 43, the graphite ring 42 can continuously lubricate the inner ring of the planetary gear shaft 43 and the thrust bearing 44 through friction, thereby reducing the coefficient of friction and wear.
[0037] like Figure 3 , Figure 4 As shown, in some embodiments, a transmission gear 45 is provided at the lower end of the planetary gear shaft 43; wherein the transmission gear 45 meshes with the fixed gear 11.
[0038] In this embodiment, since the transmission gear 45 meshes with the fixed gear 11, the planetary gear shaft 43 can rotate on its own axis while the turntable 3 rotates.
[0039] like Figure 4 As shown, in some embodiments, a retaining ring assembly 47 is fitted on the planetary gear shaft 43; wherein the retaining ring assembly 47 is used to retain the planetary gear seat 41.

[0042] In this embodiment, during the coating process, some particles will enter the annular groove 211 of the annular support base 21. In order to avoid the rotation of the turntable 3 being obstructed, this embodiment uses a deep groove ball bearing 22 and leaves a gap between the deep groove ball bearing 22 and the bottom of the annular groove 211, thereby avoiding the rotation of the deep groove ball bearing 22 being obstructed.
[0043] like Figure 2 As shown, in some embodiments, a limiting notch 212 is provided on the annular support base 21; a rotating shaft 221 is provided on the deep groove ball bearing 22; wherein, the rotating shaft 221 is disposed in the limiting notch 212 so that the deep groove ball bearing 22 is rotatably disposed on the annular support base 21.
[0044] In this embodiment, in order to stabilize the rotation of the turntable 3, the positions of each deep groove ball bearing 22 are fixed, thereby preventing the position of the deep groove ball bearing 22 from deviating.
[0045] like Figure 5 As shown, in some embodiments, the lower surface of the turntable 3 is provided with an annular groove 31; wherein the upper part of the deep groove ball bearing 22 is placed in the annular groove 31; the rotating assembly 2 also includes: a first dustproof ring 23 and a second dustproof ring 24; the first dustproof ring 23 and the second dustproof ring 24 are respectively located on both sides of the annular support base 21.

[0047] like Figure 4 As shown, at least one embodiment also provides a planetary gear assembly for a rotating base of a coating fixture, including: a planetary gear seat 41, a graphite ring 42, and a planetary gear shaft 43; wherein the planetary gear seat 41 is rotatably mounted on a turntable 3, the planetary gear shaft 43 passes through the planetary gear seat 41, and the graphite ring 42 is sleeved on the planetary gear shaft 43 and located inside the planetary gear seat 41; when the turntable 3 rotates, the planetary gear shaft 43 rotates on its own axis while revolving around the sun.
[0048] In this embodiment, the turntable 3 rotates by the drive of the motor, thereby driving the planetary gear assembly 4 to rotate while revolving around the sun; during the rotation of the planetary gear assembly 4, the planetary gear shaft 43 rotates relative to the planetary gear seat 41. At this time, the graphite ring 42 can continuously lubricate the planetary gear shaft 43 through friction, thereby greatly reducing the coefficient of friction and wear.
[0049] In some embodiments, the planetary gear assembly 4 further includes: a thrust bearing 44; wherein the thrust bearing 44 is sleeved on the planetary gear shaft 43 and located inside the planetary gear seat 41; a graphite ring 42 is located above the thrust bearing 44; and a transmission gear 45 is provided at the lower end of the planetary gear shaft 43; wherein the transmission gear 45 meshes with the fixed gear 11.
[0050] In this embodiment, the presence of the graphite ring 42 can serve as a radial limit to prevent the planetary gear shaft 43 from tilting or wobbling. Therefore, during the rotation of the planetary gear shaft 43, the graphite ring 42 can continuously lubricate the inner ring of the planetary gear shaft 43 and the thrust bearing 44 through friction, thereby reducing the coefficient of friction and wear.
[0051] In summary, the rotating base and planetary gear assembly of this coating fixture are driven by a motor to rotate, thereby driving the planetary gear assembly 4 to rotate while revolving around the sun. During the rotation of the planetary gear assembly 4, the planetary gear shaft 43 rotates relative to the planetary gear seat 41. At this time, the graphite ring 42 can continuously lubricate the planetary gear shaft 43 through friction, thereby greatly reducing the coefficient of friction and wear.
