Determine to prevent output gear 30 from vibrating during operation, and is rotated with the rotation of output gear 30.In other realities
It applies in mode, connecting shaft 18 can be not fixed with output gear 30.
Please refer to Fig. 6 to Fig. 7, planetary gear 20 includes gear part 21 and the first linkage portion 25, gear part 21 it is outer
Periphery is equipped with spaced tooth, and the first linkage portion 25 is located at gear part 21 back to the side of internal gear 14, the first linkage portion
25 are provided with equally distributed multiple set bars 24 on the face of gear part 21, and in the present embodiment, set bar 24 is substantially in
Cylindrical shape, and quantity is nine.In other embodiments of the invention, set bar 24 be not limited to the present embodiment in cylinder
Body shape, quantity are also smaller than nine or greater than nine.Gear part 21 and the concyclic heart of the first linkage portion 25, the first linkage portion 25
Diameter is slightly larger than the diameter of gear part 21, but is slightly less than the diameter of circular groove 147 in internal gear 14, so that the first linkage portion
25 can partial receipt in circular groove 147.
Please refer to Fig. 7 and Fig. 8, the center of circle of each set bar 24 is using the axle center of planetary gear 20 as the circumference in the center of circle
On.In an embodiment of the present invention, planetary gear 20 is set on the eccentric part 155 in eccentric wheel 15, and planetary gear 20
Gear part 21 is meshed with ring gear 146.Bushing 16 is provided between planetary gear 20 and eccentric wheel 15, bushing 16 can reduce row
Vibration and abrasion between star gear 20 and eccentric part 155 reduce noise, improve the service life of transmission mechanism 10.Bushing 16
It is made of corrosion resistant and/or wear-resistant material, such as polytetrafluoroethylene (PTFE) or graphite etc..
In the present embodiment, there are few teeth difference passes between the gear part 21 of planetary gear 20 and the ring gear 146 of internal gear 14
System, and tooth difference between the two is 1-2, since there are few teeth differences, when 50 rotary motion one of motor circle, internal gear 14 rotations
1-2 tooth, transmission at this time are bigger.
Please refer to Fig. 9 to Figure 10, output gear 30 connects including the second linkage portion 31, with what the second linkage portion 31 was connect
Portion, company 34 and the output section 35 being connect with joins 34, first linkage of second linkage portion 31 in planetary gear 20
Portion 25 opens up pin hole 33 in second linkage portion 31, and the position of pin hole 33 and the position of set bar 24 correspond, for accommodating
Set bar 24 in first linkage portion 25.The diameter of pin hole 33 is greater than the diameter of set bar 24.Joins 34 is substantially cylindrical,
Its diameter is slightly less than the diameter of round hole 1110, and is housed in round hole 1110, in order to which joins 34 can be in round hole
Rotary motion in 1110.In present embodiment, output section 35 is external gear, opens up pass through aperture 351 thereon, through hole 351 passes through
Output section 35, joins 34 and the second linkage portion 31 are worn, to accommodate connecting shaft 18.In the present embodiment, the circle of each pin hole 33
The heart is on the circumference using the axle center of output gear 30 as the center of circle, and the quantity of pin hole 33 is similarly nine.
Figure 11 is please referred to, each corresponding set bar 24 is axially inserted into each pin hole 33 respectively, makes output gear
30 form interaction relation with planetary gear 20.Due to there is eccentric presence, the aperture of pin hole 33 should be greater than the diameter of set bar 24.
In transmission mechanism 10, the aperture of pin hole 33, the diameter of set bar 24 and eccentric wheel 15 meet following relationship: (d/2)+e
=(D/2), wherein D is the aperture of pin hole 33, and d is the diameter of set bar 24, and e is the eccentricity of eccentric wheel 15, and eccentric distance e is
Spacing between the axis of second gear 13b and the axis of eccentric wheel 15, under the setting, transmission mechanism 10 can be rotated steadily, and
Have the characteristics that low noise, low vibration.
Because planetary gear 20 is limited by internal gear 14 and eccentric wheel 15, make circumference translation around the central axis of internal gear 14
Movement, while also making rotary motion around own axes, due to the position of the output axis of output gear 30 be it is fixed, because
The rotary motion of planetary gear 20 must could be transmitted to outside by a gear unit by this.In an embodiment of the present invention, it adopts
Planetary gear 20 and output gear 30 with pin-hole type export structure is used to transport the revolution of planetary gear 20 as gear unit
Dynamic to be transmitted to outside, the pin-hole type export structure and traditional floating driver plate compare, and have simple and compact for structure, part reduction
And the advantages of cost can be reduced.
The following are a kind of assembling modes of the chair regulator 100 of embodiment of the present invention: first gear 13a is covered in electricity
It on the output shaft 55 of machine 50 and is contained in the second receiving portion 116, injection molding eccentric wheel 15 and second gear 13b is put into
In first receiving portion 115, and second gear 13b is engaged with first gear 13a at intercommunicating pore 1152, internal gear 14 is set
In on second shell 11b, and make three the first pilot holes 1411 on internal gear 14 and three fixation holes in second shell
1171 are aligned one by one, and the first linkage portion 25 of planetary gear 20 is placed in circular groove 147, its gear part 21 and internal gear are made
Ring gear 146 in 14 is meshed, and a bushing 16 is arranged between planetary gear 20 and eccentric wheel 15, in output gear 30
On the set bar 24 in the first linkage portion 25, one end of connecting shaft 18 passes through output section 35 for 33 sets of pin hole in two linkage portions 31
Through hole 351 sequentially pass through output gear 30, planetary gear 20, internal gear 14, eccentric wheel 15 and second gear 13b, finally
It arrives at second shell 11b to be simultaneously contained in positioning region 118, by the position of the first mounting hole 1141 on first shell 11a and the
One pilot hole 1411 and fixation hole 1171 are aligned, several screw bolt passes the first mounting holes 1141,1411 and of the first pilot hole
Fixation hole 1171 is simultaneously fixed, to complete the assembling of chair regulator 100.
In an embodiment of the present invention, the power transmission of transmission mechanism 10 is realized by gear drive, firstly, by outside one
Motor 50 drive first gear 13a by the rotary motion transmission of motor 50 to the second gear 13b being engaged with, due to bias
Wheel 15 is connect and planetary gear 20 is placed on eccentric wheel 15 with second gear 13b, therefore can be by eccentric wheel 15 by rotary motion
It is transmitted to planetary gear 20 with torque, is formed by the pin hole 33 in the set bar 24 and output gear 30 in planetary gear 20
Interaction relation and rotary motion and torque are transferred to output gear 30 from planetary gear 20, in the process, due to planet tooth
There are few teeth difference relationships between wheel 20 and the internal gear 14 being meshed therewith, and transmission mechanism 10 is made to obtain big transmission ratio,
It to realize output high torque (HT), and is compared with traditional main axle structure being made of screw rod and nut, transmission mechanism 10 realizes
It is simple and compact for structure, the characteristics of weight saving, reliable operation, low noise, low vibration.
