In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Such as Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of stable planetary reducer of output, including procapsid 100, back casing
110, input shaft 200, output shaft 120 offer internal screw thread 111, output shaft 120 1 on the inner wall of 100 lateral end panel of procapsid
It is body formed to have planet carrier 150；
Planet carrier 150 is the cylindrical structure not opened a window, and the surface of planet carrier 150 offers screw hole 152, through-hole 151 respectively,
Planetary gear 180 is connected by perforative mandrel in through-hole 151, the inner wall of mandrel offers docking screw thread, and the surface of mandrel is equal
It is socketed with wear-resistant gasket, it is borehole structure that wear-resistant gasket, which is right against at docking screw thread, is pasted with big gasket between planetary gear 180
160, big 160 surface of gasket offers waist hole 161, open-work 162 respectively, and the position of waist hole 161 is opposite with the docking position of screw thread
It answers, the position of open-work 162 is corresponding with the position of screw hole 152, is provided with fastening screw between waist hole 161 and docking screw thread, thoroughly
Lock-screw 170 is provided between hole 162 and screw hole 152；It is successively adjacent between screw hole 152 and through-hole 151 to open up, open-work 162
It is arranged in pairs between screw hole 152, is arranged in pairs between waist hole 161 and through-hole 151.
Screw hole and open-work, output shaft do not set fenestration on output shaft, are connected by big gasket with more screws, Ke Yiqi
To the effect of output shaft fenestration.When assembly, needle roller is first fixed on planet tooth by anaerobic adhesive or epoxyn
Inner wall is taken turns, the needle roller of planetary gear inner wall makes mandrel be pressed into through-hole, completes the fixation of planetary gear and output shaft in indentation mandrel,
The inner wall of mandrel offers docking screw thread, then puts wear-resistant gasket in mandrel surface.It is finally pasted between planetary gear big
Gasket is provided with fastening screw between waist hole and docking screw thread, lock-screw is provided between open-work and screw hole, to complete to go
The assembling of star-wheel reaches with front output shaft windowing effect, and assembly and disassembly is convenient, and when disassembly can prevent other from cooperating components
Damage.
The radial outside of planetary gear 180 is engaged in gear ring 240, and the radially inner side of planetary gear 180 is engaged in too
Positive gear 190, sun gear 190 connect input shaft 200, and the end face portion of output shaft 120 is equipped with output shaft spring bearing 140,
The end face portion of input shaft 200 is equipped with input shaft spring bearing 210, and the radial outside of output shaft spring bearing 140 is by procapsid
100 provide support force, and the radial outside of input shaft spring bearing 210 provides support force by back casing 110；Sun gear 190, row
Star gear 180, gear ring 240 are all made of high gear tooth-shape structure.
