Embodiment 1

[0039] see Figure 3 to Figure 12 , a planetary transmission assembly with clearance and damping adjustment functions is shown in the figure, including three modularly designed and manufactured parts of the output gear member 10, the plastic bushing 20, and the planetary gear transmission member 30. The whole planetary transmission assembly adopts the support frame 40 (the function is the same as the reduction box shell in the prior art).

[0040] See especially Figure 5 and see also Figure 3 to Figure 12In other drawings, the output gear part 10 is made of metal material, which includes an outer support shaft section 11 coaxially arranged, an output gear section 12, an inner support shaft section 13, a planetary gear transmission member installation shaft section 14 and a sun gear installation The shaft section 15, the outer support shaft section 11 and the sun gear installation shaft section 15 are located at the inner and outer ends of the entire output gear part 10, th...

Embodiment 2

[0051] see Figure 13 to Figure 16 The difference between the planetary transmission assembly with clearance and damping adjustment functions provided in this embodiment and the first embodiment is that the planetary gear transmission parts are different, and the structures of the output gear part 10, the plastic bushing 20 and the support frame 40 are the same. see Figure 13 to Figure 16 , its planetary gear transmission part 30a is also a mold part, that is, it is manufactured by a mold, so that the overall strength is high and the manufacturing cost is low. The planetary gear transmission part 30a is basically a plate-shaped part, which has a central support hole 31a that is interference fit with the inner support section 14 on the output gear part, and the planetary gear transmission part 30a The outer end surface 32a of the inner end surface 33a is uniformly formed with four radial and circumferential positioning blind holes 34a of the planetary gear transmission parts,...

Abstract

The invention discloses a planetary transmission assembly with a clearance and damping regulating function. The planetary transmission assembly is composed of three modularization-manufactured parts, namely a gear output part, a plastic bushing and a planet gear transmission piece. The plastic bushing which is arranged on the inner support shaft section of the gear output part in a sleeved mode is provided with an elastic positioning barrel section used for removing the radial clearance between the gear output part and an inner hole of a supporting frame and a corrugated edge used for removing the radial clearance between the gear output part and the supporting frame. The planet gear transmission piece is positioned in the radial direction and the circumferential direction by depending on four radial and circumferential positioning columns of the planet gear transmission piece on the plastic bushing. According to the planetary transmission assembly with the clearance and damping regulating function, the mechanism is simplified, the advantages of being few in number of the parts, high in modularization manufacturing accuracy, convenient to assemble and the like are achieved, and the manufacturing cost and the turnover cost of the parts are lowered. If the number of teeth on the output tooth section of the gear output part needs to be changed, a novel gear output part only needs to be used for replacing, and replacing of the plastic bushing and the planet gear transmission piece is needless.

Description

technical field [0001] The invention belongs to the technical field of transmission mechanisms, and in particular relates to a device with gap and damping adjustment functions applied to seats. The seat adjustment mechanism has a modular design, has stable damping and can eliminate axial gaps. Background technique [0002] At present, the transmission mechanism applied on the seat, especially the car seat, is as figure 1 and figure 2 The shown Chinese patent authorization announcement number CN202006739U discloses the planetary carrier transmission assembly 100, the planetary carrier transmission assembly 100 includes a wheel disc 110, and the wheel disc 110 is composed of a flange plate 111, a section of positioning shaft section 112 and an output gear 113 and A supporting shaft section 114 is formed. A central hole 115 is opened in the wheel disc 110 and the positioning shaft section 112 . The sun gear shaft 120 is inserted in the central hole 115 , and the sun gear 400 ...
