Abstract
The utility model discloses a hypoid gear reducing mechanism, belonging to the gear reducing mechanism. The utility model aims to provide a gear reducing mechanism with small volume, compact structure and large transmission ratio. The hypoid gear reducing mechanism comprises a gear case consisting of a case body and a case cover, and a gear arranged inside the case by a shaft, wherein, an output shaft (3) and a gear shaft (5) are arranged on the gear case, a gearwheel (2) fixed on the output shaft (3) is meshed with a gear pinion (4) fixed on the gear shaft (5), and a hypoid gear pinion (8) connected with an input shaft is meshed with a hypoid gearwheel (7) fixed on the gear shaft (5). The hypoid gear reducing mechanism has the advantages of small noise and high transmission quality, etc. and is an ideal reducing mechanism suitable for modern electric wheelchairs.
Description
Technical field:
The utility model relates to a kind of reducing gear, relates in particular to a kind of reduction gears mechanism.
Background technique:
At present, the reduction gears mechanism for needs change transmission direction adopts worm couple or cone gear pair to realize mostly.Not only distance between shafts is big for worm couple, structure is more open, and because lubrication effect is poor, frictional force is big, therefore also has defectives such as transmission efficiency is low, noise big, transmission is not steady, easy to wear, only is fit to and the low speed transmission; And the cone gear pair except exist velocity ratio and driving torque little and, equally also have defectives such as volume is big, transmission quality is poor, noise is big.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide that a kind of volume is little, compact structure, hypoid gear reducing gear that velocity ratio is big.
To achieve these goals, the utility model by the following technical solutions: it comprises the gear-box that is made of casing and case lid, is installed in gear in this case by axle; Output shaft and gear shaft are installed on the gear-box, be fixed on the output shaft gearwheel be fixed on gear shaft on pinion, the hypoid small gear that is connected with input shaft and be fixed on hypoid gearwheel engagement on the gear shaft.
Hypoid small gear and described input shaft fixedly hold together.
Compared with the prior art, the utility model has been owing to adopted a pair of intermeshing hypoid gear to substitute worm couple or cone gear pair in traditional reducing gear, thus have that volume is little, in light weight, compact structure, velocity ratio is big, transmission efficiency is high, transmission stability is good and low noise advantages; Simultaneously, because the gear teeth of shape structure can increase the contact ratio of gear teeth meshing in the shape of a spiral, so can reduce the contact stress of the gear teeth, the bearing capacity of raising gear.In addition, under the constant situation of velocity ratio, can increase the diameter that offset or dish strengthens the big end of small gear, thereby improve the intensity of small gear.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Among the figure: casing 1 gearwheel 2 output shafts 3 small gears 4 gear shafts 5 bearings 6 hypoid gearwheels 7 hypoid small gears 8 case lids 9
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～2, gear-box is made of casing 1 and case lid 9, output shaft 3 and gear shaft 5 are installed on the gear-box by bearing 6 respectively, and the gearwheel 2 that is fixed on the output shaft 3 meshes with small gear 4 engagement, hypoid small gear 8 of fixedlying connected with input shaft and the hypoid gearwheel 7 that is fixed on the gear shaft 5 on being fixed on gear shaft 5.In order to make structure compact more, hypoid small gear 8 and described input shaft can be made into an integral body.
Claims (2)
1. hypoid gear reducing gear comprises the gear-box that is made of casing and case lid, is installed in gear in this case by axle; It is characterized in that: output shaft (3) and gear shaft (5) are installed on the gear-box, be fixed on the output shaft (3) gearwheel (2) be fixed on gear shaft (5) on small gear (4) engagement, the hypoid small gear (8) that is connected with input shaft and the hypoid gearwheel (7) that is fixed on the gear shaft (5) mesh.
