Greatly, axis and the strength of gear teeth are poor, and the bearing capacity of gear-box is caused to be deteriorated.
Utility model content
Technical problem to be solved by the utility model is: in order to solve technical problem described in background technique, this is practical
It is novel to provide a kind of twin-screw gear-box, by the way that input shaft is processed as input tooth shaft, guaranteeing center away from constant premise
Under simplify gear transmission structure, facilitate assembly technology.And by helical gear engaged transmission, to achieve the effect that carry.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of twin-screw gear-box, including cabinet, input gear axle, output gear shaft one, output gear shaft two, Roller Shaft
It holds and gear wheel, input gear axle, output gear shaft one, output gear shaft two is equipped with by roller bearing in the cabinet,
Gear wheel is worn and is fixed on output gear shaft one, and gear wheel is meshed with the gear in input gear axle, output gear shaft
Gear on one is meshed with the gear on output gear shaft two.
Specifically, the gear in the input gear axle, the gear on output gear shaft one, the tooth on output gear shaft two
Wheel, gear wheel are helical gear.
Specifically, the roller bearing installed in the input gear axle is tapered roller bearing, the shaft of input gear axle
The interior steel ring of roller bearing is passed through and is fixed on, the outer rim of roller bearing is fixed in cabinet.
Specifically, the roller bearing installed on the output gear shaft one is self-aligning roller bearing, output gear shaft one
Shaft passes through and is fixed on the interior steel ring of roller bearing, and the outer rim of roller bearing is fixed in cabinet.
Specifically, the roller bearing installed on the output gear shaft two is self-aligning roller bearing, output gear shaft one
Shaft passes through and is fixed on the interior steel ring of roller bearing, and the outer rim of roller bearing is fixed in cabinet.
The beneficial effects of the utility model are: the utility model provides a kind of twin-screw gear-box, by by input shaft
Be processed as input tooth shaft, guarantee center away from it is constant under the premise of simplify gear transmission structure, facilitate assembly technology.And lead to
Helical gear engaged transmission is crossed, to achieve the effect that carry.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
1. cabinet in figure, 2. input gear axles, 3. output gear shafts one, 4. output gear shafts two, 5. roller bearings, 6. is big
Gear.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
Fig. 1 is the structural schematic diagram of the utility model.
A kind of twin-screw gear-box, including cabinet 1, input gear axle 2, output gear shaft 1, output gear shaft 24, rolling
Sub- bearing 5 and gear wheel 6, the cabinet 1 is interior to be equipped with input gear axle 2, output gear shaft 1, output by roller bearing 5
Gear shaft 24 wears and is fixed with gear wheel 6 on output gear shaft 1, and gear wheel 6 is mutually nibbled with the gear in input gear axle 2
It closes, the gear on output gear shaft 1 is meshed with the gear on output gear shaft 24.Tooth in the input gear axle 2
Wheel, the gear on output gear shaft 1, the gear on output gear shaft 24, gear wheel 6 are helical gear.The input gear
The roller bearing 5 installed on axis 2 is tapered roller bearing, and the shaft of input gear axle 2 passes through and is fixed on the interior of roller bearing 5
Steel ring, the outer rim of roller bearing 5 are fixed in cabinet 1.The roller bearing 5 installed on the output gear shaft 1 is aligning
The shaft of roller bearing, output gear shaft 1 passes through and is fixed on the interior steel ring of roller bearing 5, and the outer rim of roller bearing 5 is solid
It is scheduled in cabinet 1.The roller bearing 5 installed on the output gear shaft 24 is self-aligning roller bearing, output gear shaft 1
Shaft passes through and is fixed on the interior steel ring of roller bearing 5, and the outer rim of roller bearing 5 is fixed in cabinet 1.
As shown in Fig. 1, the input gear axle 2 of rotation, by engaging for gear in input gear axle 2 and gear wheel 6,
To drive the rotation of gear wheel 6.Fixed output gear shaft 1 can synchronous rotary with gear wheel 6.The output gear shaft one of rotation
3 can be meshed by the gear on output gear shaft 1 with the gear on output gear shaft 24, drive output gear shaft 24 into
Row synchronous rotary.
Input shaft is processed as input gear axle 2 by the utility model, guarantee center away from it is constant under the premise of simplify tooth
