Abstract
The utility model relates to a vertical speed reducer of multirow star gear revolving rack flip-chip, including box, input shaft, bearing, planetary gear train and output flange dish, its characterized in that: the input shaft is provided with a driving bevel gear, the driven bevel gear is arranged on a driven gear shaft containing a small gear, the driven gear is provided with a large gear, the driving bevel gear is meshed with the driven bevel gear, the small gear on the driven gear shaft is meshed with the large gear on the driven shaft, the driven shaft is connected with a sun gear shaft in the planetary gear train through a coupling inner gear sleeve, and the output flange plate is connected with a planet carrier in the planetary gear train through a bolt and a pin. The advantages are that: 4-6 planet gears which are uniformly distributed are arranged on a planet carrier in the planetary gear train, so that the strength of a planetary gear pair is improved; the bearing supporting point of the planet carrier moves downwards to reduce the total height of the speed reducer, and the gravity center of the speed reducer moves downwards, so that the structure is more compact, and the operation is more stable.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of multirow star-wheel pivoted frame upside-down mounting vertical type speed reducer (change gear).
Background technique
What the planetary structure of vertical type speed reducer (change gear) was used at present all is three planet wheels, the output shaft of planet carrier is on top, the strong point of its sliding bearing is in the upper support of planet carrier, bigger for planetary pinion pair diameter dimension like this, the center of gravity of casing is than higher, and the vibration of speed reducer and stability are poor.How to reduce the volume of speed reducer, the stability that improves speed reducer becomes the problem that people pay close attention to.
Summary of the invention
The purpose of this utility model is: bigger at ubiquitous volume ratio in the present vertical type speed reducer (change gear), center of gravity is than higher, and the practical problem that stability is poor provides a kind of speed reducer of new vertical carrying torsion pass.
The purpose of this utility model is achieved in that a kind of speed reducer of vertical carrying torsion pass, comprise casing, input shaft, bearing, planetary gear train and output flange, it is characterized in that: input shaft is provided with drive bevel gear, be located on the passive tooth wheel shaft that contains small gear by dynamic bevel gear, follower is provided with gearwheel; Input shaft, passive tooth wheel shaft and follower are positioned in the casing by bearing; Drive bevel gear with meshed by dynamic bevel gear, small gear on the passive tooth wheel shaft and the engagement of the gearwheel on the driven shaft, driven shaft is connected with sun wheel shaft in the planetary gear train by connecting internal tooth casing, and output flange is connected with planet carrier in the planetary gear train by bolt and pin.
In the utility model: small gear on the passive tooth wheel shaft and the gearwheel on the follower are crowned teeth, drive bevel gear and be crin root fort bevel gear or Jackie Gleason gear by dynamic bevel gear, the speed reducer output terminal is provided with bearing support, and the output flange that is connected with planet carrier places the output terminal of speed reducer by thrust-bearing.
In the utility model: the planet carrier bottom in the planetary gear train is provided with the sliding bearing that is used to support, and planet carrier is provided with 4～6 equally distributed planet wheels, and planet carrier and planet wheel shaft are provided with oilhole.
Advantage of the present utility model is: because the planet carrier in the planetary gear train is provided with 4～6 equally distributed planet wheels, improved the intensity of planetary pinion pair; The bearings point of planet carrier moves down the total height that has reduced speed reducer, because the center of gravity of speed reducer moves down, structure is compact more, and it is more steady to turn round.
