Abstract
The utility model discloses a parallel-axis helical gear reducer, which comprises a box body. A motor, a gear shaft, a linkage shaft and an output shaft are arranged on the box body. A driving gear is sleeved on the output shaft of the motor and the gear shaft is equipped with a driven gear engaged with the driving gear. The gear shaft and the linkage shaft are respectively equipped with mutually engaged helical gears. The linkage shaft is also equipped with a linkage gear engaged with the output gear sleeved on the output shaft. Deep groove ball bearings are arranged not only between the gear shaft and the box body but also between the linkage shaft and the box body. A tapered roller bearing is arranged between the output shaft and the box body. By adopting the above structure, the rotation of the gear shaft is driven by the motor and the rotation of the output shaft is driven via the linkage shaft by the gear shaft so as to achieve the whole deceleration process of the reducer. The reducer of the utility model is less in transmission links, compact and simple in structure and convenient in maintenance.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of parallel axes helical speed reduction gear.
Background technique
At present, the old-fashioned speed reducer of existing tradition adopts cycloidal-pin wheel formula, worm and gear reducing transmission structure mostly, its reduction speed ratio and transmission efficiency have certain narrow limitation, and power consumption is big, noise is big, volume is big, working life is short, maintenance and repair expense height, do not utilize and use and promote.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of simple and compact for structure, long service life and has been convenient to the parallel axes helical speed reduction gear of maintenance and repair.
For achieving the above object, the utility model provides a kind of parallel axes helical speed reduction gear, comprise casing, be equipped with motor, gear shaft, couple axle, output shaft on the casing, be arranged with driving gear on the output shaft of motor, gear shaft is provided with the driven gear that is meshed with described driving gear, is respectively equipped with intermeshing helical gear on gear shaft and the couple axle, also is provided with the linkage gear that is meshed with sheathed output gear on the output shaft on the couple axle.
The beneficial effects of the utility model are: adopt said structure, motor rotation driven gear axle rotates, gear shaft drives the output shaft rotation by couple axle, thereby realize the whole moderating process of speed reducer, so speed reducer provided by the utility model, its transmission link is few, and is simple and compact for structure and be convenient to maintenance and repair.
The utility model can further be set to be equipped with deep groove ball bearing between described gear shaft and the casing and between couple axle and the casing.
The utility model also can further be set to be provided with tapered roller bearing between described output shaft and the casing.
