Grade epicyclic transmission mechanism and secondary planet transmission mechanism, output flange include the connection being rotatablely connected with fixed seat 1 by bearing
Portion 3, the end cap 4 for being arranged on end and the housing 5 being arranged between connecting portion 3 and end cap 4, end cap 4 have discoid end cap 4
Ontology, the circular rib portion 41 for being arranged on 4 ontology peripheral portion of end cap, self catcher edge 41 reach out to for connecting
3 mutually fixed fixed part 42 of portion, from 4 body central of end cap to output shaft protrusion circular boss 43 and be detachably embedded
Locating piece 44 at 43 center of boss.
Circular boss 43 is provided on end cap 4 and dismountable locating piece 44 is set on boss 43, works as positioning
Block 44 replaces locating piece 44 after wearing, nothing needs to change entire end cap 4.It, can meanwhile if replacing locating piece 44 not in time
To mention the effect of interim locating piece 44 by boss 43, the damage of central gear is prevented.
In the present embodiment, in addition to having the caulking groove for being embedded locating piece 44 on boss 43, also have at caulking groove edge there are two connecting
The taking-up slot of logical caulking groove.It, can be by taking out the space clamping position block in slot when locating piece 44, which is smoothed, to be difficult to take out
44, locating piece 44 is taken out.
