Description
Technical field
The utility model relates to a kind of hydraulic turbine main shaft transmission device.
Background technique
In hydraulic engineering, water turbine be a kind of comparatively common be the device of mechanical energy by the kinetic energy of water and potential energy, be mainly used in water generating field, existing water turbine is all by water pipe water guide, utilize the impact force of current to impact water wheels to rotate, and then drive axis of rotation, but because the impact force of water is larger, and by water currents, the impact force of water is unstable, being easy to make the connection between water wheels and rotating shaft make to connect generation because of being subject to larger stress for a long time loosen, making total unstable.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of hydraulic turbine main shaft transmission device.
The utility model solves the technological scheme that its technical problem adopts: a kind of hydraulic turbine main shaft transmission device, comprise main shaft, four countershafts and output shaft, the axis of described main shaft and output shaft on the same line and the equal diameters of main shaft and output shaft, four countershafts are evenly arranged and the axis being parallel of the axis of countershaft and main shaft along the axis circumference of main shaft, the side of described main shaft, four countershafts and output shaft is equipped with rectangular teeth, and the two ends of described countershaft are engaged with main shaft and output shaft respectively by rectangular teeth.
As preferably, the diameter of described countershaft is equal with main shaft.
As preferably, the length of described countershaft and main shaft contact segment equals the length of countershaft and output shaft contact segment.
As preferably, between described main shaft and output shaft, be provided with gap.
The beneficial effects of the utility model are, this hydraulic turbine main shaft transmission device carries out transmission and spacing by four countershafts, and the rigidity avoiding main shaft exports, and adds the cushioning effect that main shaft is stressed, reduce the impact of stress, add the stability of total and the working life of device.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of hydraulic turbine main shaft transmission device of the present utility model;
Fig. 2 is the structural representation of hydraulic turbine main shaft transmission device of the present utility model;
In figure: 1. main shaft, 2. countershaft, 3. output shaft, 4. rectangular teeth.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1-2, a kind of hydraulic turbine main shaft transmission device, comprise main shaft 1, four countershafts 2 and output shaft 3, the axis of described main shaft 1 and output shaft 3 on the same line and the equal diameters of main shaft 1 and output shaft 3, four countershafts 2 are evenly arranged and the axis being parallel of the axis of countershaft 2 and main shaft 1 along the axis circumference of main shaft 1, the side of described main shaft 1, four countershafts 2 and output shaft 3 is equipped with rectangular teeth 4, and the two ends of described countershaft 2 are engaged with main shaft 1 and output shaft 3 respectively by rectangular teeth 4.
As preferably, the diameter of described countershaft 2 is equal with main shaft 1, and design is mainly in order to make the transmission between main shaft 1 and countershaft 2 more smooth and coordinate like this.
As preferably, described countershaft 2 and the length of main shaft 1 contact segment equal the length of countershaft 2 and output shaft 3 contact segment, and designing like this is transmission balance in order to keep countershaft 2 two ends.
As preferably, between described main shaft 1 and output shaft 3, be provided with gap, like this design be one end and output shaft 3 in order to prevent main shaft 1 one end mutually against, thus make main shaft 1 directly apply power to countershaft 2.
When main shaft 1 rotates time, main shaft 1 drives four countershafts 2 to rotate, four countershafts 2 drive output shaft 3 to rotate, here by the transmission medium of countershaft 2 as main shaft 1 and output shaft 3, add cushioning effect, and four countershaft 2 circumferences are evenly arranged on the periphery of main shaft 1, be not only in transmission connection effect, can also play good positioning action to main shaft 1.
Compared with prior art, this hydraulic turbine main shaft transmission device carries out transmission and spacing by four countershafts 2, and the rigidity avoiding main shaft 1 exports, and adds the cushioning effect that main shaft 1 is stressed, reduce the impact of stress, add the stability of total and the working life of device.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
