Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment 1
As shown in Figure 1-2, a kind of 3K-H type precision planetary gear backlash adjuster based on eccentric shaft, including ring gear
A and ring gear B, ring gear A1 and ring gear B2 can realize the interior of coaxial relative rotary motion, ring gear A1 and ring gear B2
Portion is provided with planet carrier 3, installs some compound planet gears 6 in planet carrier 3, and the size gear of each compound planet gear 6 divides
Not engaging with ring gear A1 and ring gear B2, the endoporus two ends of each compound planet gear 6 are respectively arranged with bearing 5, and eccentric shaft 4 runs through
The bearing 5 installed in the endoporus of each compound planet gear 6, eccentric shaft 4 is fixed on the both ends of the surface of planet carrier 3 by jump ring 7.
Being provided with jump ring 7 on eccentric shaft 4, jump ring 7 is stuck in the side having draw-in groove on eccentric shaft 4, and eccentric shaft 4 runs through bearing 5
With jump ring 7.Ring gear A1 and ring gear B2 fixed gear ring each other, output gear.
The internally installed of compound planet gear 6 has jump ring 7, and jump ring 7 is fixed on the side of bearing 5, and eccentric shaft 4 runs through bearing
5 and jump ring 7.Ring gear A1 and ring gear B2 fixed gear ring each other, output gear.
Assembling mode: bearing 5 loads the two ends of compound planet gear 6, by compound planet gear 6 together with loading two ends
Bearing 5 puts into the mounting groove of planet carrier 3 position, hole of aliging in the lump, by eccentric shaft 4 through planet carrier 3, bearing 5, duplex planet
Gear 6, jump ring 7 is loaded jump-ring slot by the other end to be blocked.Install 3 groups or 4 groups of compound planet gears 6 successively.Again by ring gear A1,
