Detailed description of the invention
As Fig. 1 is to shown in 2, and the gear of planetary reduction box and electric motor protective device, it includes planet carrier B9 and planet carrier
C10, planet carrier C10 include having resilient annular thin wall 101, are provided with sun gear, on annular thin wall 101 in annular thin wall 101
Along the circumferential direction being evenly equipped with multiple projection (102), planet carrier B upper 9 is along the circumferential direction evenly equipped with multiple groove 91, planet carrier C10
Projection 102 be set in the groove 91 of planet carrier B9, the present embodiment protrusions is three.
When the load in the external world is excessive, act on moment of torsion produced by the torsion on planet carrier C10 sun gear more than planet
Produced by three projections 102 on frame C10 annular thin wall 101 and groove 91 clutching force in carrier B9 during moment of torsion, planet carrier
Three projections 102 on C10 annular thin wall 101 are slided in the groove 91 of planet carrier B9, and protection gear and motor are not damaged by.
When the load in the external world is normal, act on moment of torsion produced by the torsion on planet carrier C10 sun gear less than planet carrier C10 annular
Produced by three projections 102 on thin-walled 101 and groove 91 clutching force in carrier B9 during moment of torsion, planet carrier C10 annular is thin
The geo-stationary in planet carrier B9 groove 91 of three projections 102 on wall 101, becomes an entirety, transmits load, normal work
Make.
Further, sun gear is third level sun gear 11.This sun gear can also be first order sun gear or the second level
Sun gear.
As shown in Figs. 3-4, a kind of planetary gear reduction box, it includes that motor 1, motor 1 are provided with first order sun gear 2, the
