Abstract
The invention discloses a gearbox. The gearbox comprises a box body, wherein an input shaft, an output shaft, a gear and an oil seal mechanism are arranged in the box body, the output shaft extends out of the box body, the oil seal mechanism is arranged at the position where the output shaft is in contact with the box body, the input shaft is in transmission with the output shaft through the gear, the gear comprises a first gear set, a second gear set and a third gear set, the second gear set is meshed with the first gear set and the third gear set, the second gear set is fixed to a gear carrier, and the gear carrier is fixed inside the box body. The gearbox has the advantages that the structure is simple, installation and using are convenient, the working efficiency is improved, the occupied area is small, space is saved, the performance is stable during operation, and the service life is prolonged greatly.
Description
Technical field
The present invention relates to a kind of speed reducer.
Background technique
The installation process of existing conventional speed reducer is more complicated, and process is more, and installation efficiency is lower.And the shared space of existing speed reducer is larger, and the driving force requiring more the shared space of big retarding case is just larger.If the limited space of environment and require driving force larger, existing speed reducer just cannot meet use.
Therefore,, for addressing the above problem, spy provides a kind of new technological scheme.
Summary of the invention
The invention provides a kind of speed reducer.
The technical solution used in the present invention is:
A kind of speed reducer, comprise casing, in described casing, be provided with input shaft, output shaft, gear and oil seal mechanism, described output shaft extends to casing outside, the contacting point of described output shaft and casing is provided with oil seal mechanism, between described input shaft and output shaft by gear transmission, described gear comprises the first gear train, the second gear train and the 3rd gear train, described the second gear train is intermeshing with the first gear train and the 3rd gear train respectively, described the second gear train is fixed on gear carrier, and described gear carrier is fixed on box inside.
Described oil seal mechanism comprises oil sealing and oil seal cover, and the contacting point of described output shaft and casing is provided with oil sealing, and described oil sealing outside seals by oil seal cover.
Between described gear carrier and casing, be fixed with stiffening rib.
The invention has the beneficial effects as follows: simple in structure, easy to install and use, improve working efficiency, floor space is little, has saved space, and in the time of running, stable performance, has extended working life greatly.
