Specific embodiment
The utility model is described further below by accompanying drawing and example.
Mechanical soft start planetary reduction gear shown in accompanying drawing 1 is one embodiment of the present utility model, and it is by being input into the sun
Wheel shaft 1, output shaft 25, decelerator casing, planetary transmission system and buffering transition apparatus, wherein decelerator casing is divided into input
Casing 5 and output end casing 23, planetary transmission system is shown in accompanying drawing 2, including sun gear part, the planetary gear of input sun wheel shaft 1
13rd, planet wheel spindle 12, deep groove ball bearing 11, ring gear 27 and planet carrier 9；Buffering transition apparatus are shown in accompanying drawing 3, by input chassis
16th, spring installing plate 29, extension spring 28, spring catch 31, spring catch 32, flat key 20, screw 30 and 19 groups of frame of output are input into
Into.
Input sun wheel shaft 1 is arranged on input casing 5 by deep groove ball bearing 3, and input sun wheel shaft passes through zanjon
Ball bearing is connected with output shaft 25；Input sun wheel shaft 1 and planetary gear 13 are connected；Planetary gear 13 and the transmission of ring gear 27 connect
Connect；Planetary gear 13 is installed in planet carrier by planet wheel spindle 12, and planet wheel spindle is connected by deep groove ball bearing 11 with planet carrier；
Planet carrier 9 and input chassis 16 are connected by screw, and are arranged in input sun wheel shaft by deep groove ball bearing 6；Input machine
Frame 16 is arranged on output end casing and ring gear by deep groove ball bearing 14, and is arranged on output by deep groove ball bearing 17
On axle；Input spring installing plate 29 and input chassis 16 are connected by screw 30, and by extension spring 28 and output frame 19
It is connected, extension spring 28 is connected respectively by spring catch 31 and spring catch 32 with input spring installing plate and output frame；Output
Frame 19 is connected by flat key 20 with output shaft 25；Output shaft 25 is arranged on output end casing by deep groove ball bearing 22；
Sealed using O-ring seal 10 between input casing 5 and ring gear 27, output end casing 23 and ring gear 27
