Transmission mechanism;
The output shaft includes the axostylus axostyle and beam barrel being coaxially disposed, and beam barrel is the cylindrical housings that right side is opened wide and axle
Bar right-hand member connects beam barrel left-hand end plate;The end cap is arranged on the right side of beam barrel so as to close beam barrel inner chamber, Gear Planet Transmission
Mechanism is arranged in beam barrel inner chamber, for supporting the bearing that output shaft rotates to be separately positioned on the both sides of epicyclic transmission mechanism.
The epicyclic transmission mechanism include be arranged on input shaft left end sun gear, be arranged on it is interior on beam barrel inner peripheral surface
Gear ring and the planetary gear engaged with sun gear and ring gear.
The axostylus axostyle of the output shaft is rotatably positioned on support base by the first output shaft bearing, the beam barrel of output shaft
It is rotatably positioned by the second output shaft bearing on end cap, input shaft is rotatably positioned in end cap by bearing of input shaft
On.
The end cap is provided with the boss that stretches into beam barrel inner chamber, the second output shaft bearing be arranged on beam barrel and boss it
Between.
The bearing pin is fixed as one by supporting plate.
The protective cover for surrounding output shaft beam barrel is additionally provided with the base.
The beneficial effects of the invention are as follows:
Independent casing is set outside transmission mechanism with conventional reductor and output shaft bearing is set in casing side
Structure it is different, in the present invention, output shaft as reductor casing and supported by base, epicyclic transmission mechanism is equal with lubricating oil
It is stored in the beam barrel of output shaft, bearing is arranged on the both sides of output shaft beam barrel, in the case where reducing volume, improves deceleration
The stability of machine, the sealing property of reductor is enhanced, reduces operating cost;It can more overcome completely when using vertical installation
Oil leak defect, using effect are particularly evident and prominent.
