Abstract
The utility model discloses a zero bevel gear power transmission mechanism which comprises a big bevel gear and a small bevel gear, wherein the curved teeth of the big bevel gear and the small bevel gear are meshed; and the curved teeth of the big bevel gear and the small bevel gear are zero curved teeth. In the utility model, the curved teeth of the big bevel gear and the small bevel gear are set as the zero curved teeth; and when the zero big bevel gear and the zero small bevel gear are meshed to transmit power, the transmission stability is better, the noise is low, the power loss is low, the assembling axial force is smaller, the damage degree to the bearing of a tank body is smaller, and the bending resistance is better.
Description
Technical field
The utility model relates to a kind of agricultural ploughing machine decelerator Poewr transmission mechanism, relates in particular to a kind of zero bevel gear Poewr transmission mechanism.
Background technology
At present, the commonplace Poewr transmission mechanism that adopts on farm machinery mainly contains gear transmission, and gear has and divides roller gear transmission and Bevel Gear Drive, and Bevel Gear Drive both can change the direction of transmission of power, can change the rotating speed of power output simultaneously.
In the prior art, it is 10 °～35 ° arc bevel gear (as shown in Figure 2) that conical gear commonly used has straight bevel gear (as shown in Figure 1) and radian.Advantages such as straight bevel gear has that power loss is little, the assembling axial force is little, little and bending resistance is good to the damaged condition of casing bearing, but exist working (machining) efficiency low, shortcoming such as transmission stability difference and noise are big; The arc bevel gear has working (machining) efficiency height, transmission stability is good and noise is little advantage, but have that power loss is big, the assembling axial force is big, the shortcoming such as big and anti-bending strength difference to the damaged condition of casing bearing.
The utility model content
At the prior art above shortcomings, the utility model provides a kind of working (machining) efficiency height, transmission stability is better, noise is less, the transmitted power loss is less, the assembling axial force is less, less to the damaged condition of casing bearing, anti-bending strength good and the zero bevel gear Poewr transmission mechanism of longer service life.
A kind of zero bevel gear Poewr transmission mechanism that the utility model provides comprises curved tooth bevel gear wheel and curved tooth bevel pinion, the tooth engagement mutually of the curved tooth of described curved tooth bevel gear wheel and curved tooth bevel pinion; The curved tooth of described curved tooth bevel gear wheel and curved tooth bevel pinion is the zero degree curved tooth.
Further, pressure angle а=25 of described curved tooth bevel gear wheel and curved tooth bevel pinion °.
The beneficial effects of the utility model: the curved tooth of the utility model curved tooth bevel gear wheel and curved tooth bevel pinion is set to the zero degree curved tooth, when zero degree curved tooth bevel gear wheel and zero degree curved tooth bevel pinion engagement transferring power, it is better to have transmission stability, noise is low, power loss is little, the assembling axial force is less, and less to the damaged condition of casing bearing, anti-bending strength is better.

Fig. 1 is the structural representation of straight bevel gear in the prior art;
Fig. 2 is the structural representation of arc bevel gear in the prior art;
Fig. 3 is the structural representation of zero bevel gear Poewr transmission mechanism of the present utility model;
Fig. 4 is the structural representation of curved tooth bevel gear wheel;
Fig. 5 is the structural representation of curved tooth bevel pinion.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
Fig. 3 is the structural representation of zero bevel gear Poewr transmission mechanism of the present utility model, and Fig. 4 is the structural representation of curved tooth bevel gear wheel, and Fig. 5 is the structural representation of curved tooth bevel pinion, as shown in the figure.Rotovator decelerator zero bevel gear Poewr transmission mechanism comprises curved tooth bevel gear wheel 1 and curved tooth bevel pinion 2, the tooth engagement mutually of the curved tooth of curved tooth bevel gear wheel 1 and curved tooth bevel pinion 2; The curved tooth of described curved tooth bevel gear wheel 1 and curved tooth bevel pinion 2 is the zero degree curved tooth.Pressure angle а=25 of curved tooth bevel gear wheel 1 and curved tooth bevel pinion 2 °.
The curved tooth of the utility model curved tooth bevel gear wheel and curved tooth bevel pinion is set to the zero degree curved tooth, when zero degree curved tooth bevel gear wheel and zero degree curved tooth bevel pinion engagement transferring power, it is better to have transmission stability, noise is low, power loss is little, the assembling axial force is less, and less to the damaged condition of casing bearing, anti-bending strength is better.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
