Abstract
The utility model relates to a split type pair roller gear, including first gear, second gear and connecting axle, open threaded hole on the terminal surface of first gear, also open threaded hole on the terminal surface of second gear, the connecting axle is the I shape, the connecting axle is including the first connecting portion that connect gradually, intermediate part and second connecting portion, first connecting portion open have with the corresponding through -hole of first gear screw hole, the second connecting portion open have with the corresponding through -hole of second gear screw hole, the both ends of connecting axle are respectively through bolt and first gear and second gear fixed connection. The utility model discloses set up dual gea into dividing the body structure, convenient to detach, the same tooth wheel does not make up in order to satisfy different output speed requirements, can dismantle rear portion branch change when the gear distress needs to be changed, the cost is reduced.
Description
Technical field
This utility model is related to gear technique field, especially a kind of Split type duplex roller gear.
Background technology
Gear drive is the most widely used kind of drive in machine driving, it is ensured that stable transmission, has transmission
Efficiency high, the advantage of life-span length.Duplicate gear is exactly that two gears are connected, this duplicate gear (variator) in train
It is referred to as shifting slide gear, its effect is exactly rotating speed or the speed changing output shaft.Two number of gear teeth of duplicate gear are one
Fixed, for same duplicate gear, it is also fixing that the rotating speed of output shaft changes；And gear is easily worn part, need through
Often change, traditional duplicate gear is structure as a whole, and needs integral replacing, increased cost.
Utility model content
The technical problems to be solved in the utility model is：It is structure as a whole to solve existing duplicate gear, output shaft
Rotating speed to change be fixing, need integral replacing during replacing, relatively costly problem, a kind of Split type duplex Cylinder Gear is provided
Wheel.
This utility model solves its technical problem and be employed technical scheme comprise that：A kind of Split type duplex roller gear, bag
Include first gear, second gear and connecting shaft, the end face of described first gear has screwed hole, the one of described second gear
Also screwed hole is had, described connecting shaft is I shape, described connecting shaft includes first connecting portion, the centre being sequentially connected on end face
Portion and second connecting portion, described first connecting portion has the through hole corresponding with described first gear screwed hole, and described second even
Socket part has the through hole corresponding with described second gear screwed hole, and the two ends of described connecting shaft pass through bolt and the first tooth respectively
Wheel is fixedly connected with second gear.Using connecting shaft, first gear and second gear are connected and composed duplicate gear, first gear
It is connected with connecting shaft by bolt respectively with second gear, easy to connect and easy to disassemble, can output speed as needed
Different gears is combined, meets different output speed demands；When geared parts damage needs to change, can be double
Connection gear disassembling changes broken parts, without integral replacing, reduces cost；Connecting shaft adopts I-shaped structure, and first
Between connecting portion and second connecting portion, there is gap, be easy to tighten and demounting bolt.
The both ends of the surface of described first gear and second gear all have lightening grooves, and described screwed hole is opened in the bottom of lightening grooves
Portion, alleviates the overall weight of duplicate gear, alleviates live load.
Described connecting shaft is quill shaft, alleviates the overall weight of duplicate gear, alleviates live load.
The beneficial effects of the utility model are that duplicate gear is set to Split type structure by this utility model, easy to disassemble, can
Different gears are combined requiring to meet different output speeds, when gear failure needs to change detachably afterwards partly more
Change, reduce cost.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure：1. first gear, 2. second gear, 3. first connecting portion, 4. pars intermedia, 5. second connecting portion, 6. bolt,
7. lightening grooves.
Specific embodiment
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with this utility model.
As shown in figure 1, a kind of Split type duplex roller gear, including first gear 1, second gear 2 and connecting shaft, described
Screwed hole is had on the end face of first gear 1, the end face of described second gear 2 also has screwed hole, described connecting shaft
For I shape, described connecting shaft includes first connecting portion 3, pars intermedia 4 and the second connecting portion 5 being sequentially connected, and described first even
Socket part 3 has the through hole corresponding with described first gear 1 screwed hole, and described second connecting portion 5 has and described second gear 2
The corresponding through hole of screwed hole, the two ends of described connecting shaft are passed through bolt 6 respectively and are fixed even with first gear 1 and second gear 2
Connect.Using connecting shaft, first gear 1 and second gear 2 are connected and composed duplicate gear, first gear 1 and second gear 2 are respectively
It is connected with connecting shaft by bolt 6, easy to connect and easy to disassemble, can different gears be entered output speed as needed
Row combination, meets different output speed demands；When geared parts damage needs to change, can be by duplicate gear dismounting and change
Broken parts, without integral replacing, reduce cost；Connecting shaft adopts I-shaped structure, and first connecting portion 3 and second connects
Between socket part 5, there is gap, be easy to tighten and demounting bolt 6.In order to mitigate the overall weight of duplicate gear, mitigate work and bear
Carry, the both ends of the surface of described first gear 1 and second gear 2 all have lightening grooves 7, and described screwed hole is opened in the bottom of lightening grooves 7
Portion, described connecting shaft is quill shaft.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality
The content being not limited in description with new technical scope it is necessary to determine its technology according to right
Property scope.
