Abstract
The utility model discloses a bevel and helical gear reducer, which comprises a machine body, wherein an input shaft, an output shaft and a gear shaft are assembled on the machine body; a small bevel gear is sleeved on one end of the input shaft; a big bevel gear which is meshed with the small bevel gear on the input shaft is sleeved on the gear shaft; a small gear which is meshed with a big gear which is sleeved on the output shaft is sleeved on the gear shaft; small teeth difference meshing is formed between the small bevel gear and the big bevel gear; and the big gear and the small gear form the small teeth difference meshing; both the big bevel gear and the small bevel gear are helical gears, the central axes of the input shaft is perpendicular to the central axes of the gear shaft, and the central axes of the output shaft is parallel to the central axes of the gear shaft. In the reducer provided by the utility model, the transmission link is less, the structure is simple and compact; and the reducer is convenient to maintain.
Description
Technical field
The utility model relates to a kind of speed reducer, especially a kind of umbrella tooth 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 umbrella tooth helical speed reduction gear of maintenance and repair.
For achieving the above object, the utility model provides a kind of umbrella tooth helical speed reduction gear, comprise body, be equipped with input shaft, output shaft, gear shaft on the body, be arranged with bevel pinion on one end of input shaft, be arranged with the large bevel gear that is meshed with bevel pinion that input shaft is provided with on the gear shaft, also be arranged with on the gear shaft with output shaft on sheathed gearwheel pinion in mesh, constitute few tooth difference engagement between described bevel pinion and the large bevel gear, gearwheel and small gear constitute few tooth difference engagement.
The beneficial effects of the utility model are: owing to constitute few tooth difference engagement between bevel pinion and the large bevel gear, gearwheel and small gear constitute few tooth difference engagement, so input shaft rotating band movable gear shaft rotates, gear shaft drives output shaft and rotates, thereby realize the whole moderating process of speed reducer, therefore 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 described large bevel gear and bevel pinion is skew bevel gear.
It is perpendicular that the utility model also can further be set to the central axis of the central axis of input shaft and gear shaft, and the central axis of output shaft is parallel with the central axis of gear shaft.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
Embodiment
Provided a kind of umbrella tooth helical speed reduction gear as shown in Figure 1, comprise body 1, be equipped with input shaft 2 on the body 1, output shaft 3, gear shaft 4, be arranged with bevel pinion 21 on one end of input shaft 2, be arranged with the large bevel gear 41 that the bevel pinion 21 that is provided with input shaft 2 is meshed on the gear shaft 4, also be arranged with on the gear shaft 4 with output shaft 3 on sheathed gearwheel 31 pinion in mesh 42, constitute few tooth difference engagement between described bevel pinion 21 and the large bevel gear 41, gearwheel 31 constitutes few tooth difference engagement with small gear 42, and described large bevel gear 41 is skew bevel gear with bevel pinion 21, the central axis of the central axis of input shaft 2 and gear shaft 4 is perpendicular, and the central axis of output shaft 3 is parallel with the central axis of gear shaft 4.
