Smooth degree is engaged between gear and gearbox-case internal tooth.
The technical solution of the utility model is：A kind of multi-section type gear box structure, including shell, be arranged in shell four
Level planetary gear mechanism, input mechanism and output shaft, the level Four planetary gear mechanism have been sequentially arranged above
Bearing A and bearing B, one end of the output shaft is connected with level Four planetary gear mechanism, the other end of the output shaft according to
It is secondary through bearing A and bearing B and outside extending shell, the shell includes output end cap, the first containment vessel, the second protection
Shell, input end cap, the output end cap and the first containment vessel, the first containment vessel and the second containment vessel, the second containment vessel and input
End cap is threaded connection, and the madial wall of first containment vessel and the second containment vessel is provided with and level Four planetary gear is passed
The internal tooth that motivation structure coordinates.
Preferably, the level Four planetary gear mechanism includes primary planet pinion transmission mechanism, two grades of rows
Star gear drive, three-stage planetary gear transmission mechanism, level Four planetary gear mechanism, first containment vessel and three-level
Planetary gear mechanism, level Four planetary gear mechanism are equipped with；Second containment vessel is passed with primary planet pinion
Motivation structure, secondary planetary gear transmission mechanism are equipped with.
Preferably, the output end cap, the first containment vessel, the second containment vessel, input end cap are disposed as metal
Housing.
Compared with prior art, a kind of multi-section type gear box structure described in the utility model, including output end cap, first
Containment vessel, the second containment vessel, input end cap, output end cap and the first containment vessel, the first containment vessel and the second containment vessel, second protect
Protective case is with input end cap and is threadedly coupled, and instead of the company being fixed together by some connecting bolts long in the prior art
Mode is connect, packaging technology is on the one hand simplified, output end cap, the first containment vessel, the second containment vessel, input is on the other hand ensure that
The concentric degree of end cap, ensures that the first containment vessel, the first containment vessel engage smooth degree with internal tooth.
