Abstract
An eccentric shaft for agricultural lawn mowers is widely used in agricultural lawn mowers. During work, blades of an agricultural lawn mower can be driven by an eccentric shaft section of the eccentric shaft to move back and forth. The Eccentric shaft for agricultural lawn mowers comprises an eccentric shaft body, wherein a plurality of spline grooves are arranged at one end of the eccentric shaft body. The service life of the eccentric shaft for agricultural lawn mowers can be effectively prolonged.
Description
Technical field:
The utility model relates to a kind of axle, specifically is a kind of agricultural mowing machine eccentric shaft.
Background technique:
As everyone knows, eccentric shaft is a kind of of a class part, because it is the solid of rotation eccentric element, therefore is widely used in the agricultural mowing machine, and during work, the blade that drives on the agricultural mowing machine by self eccentric shaft part back and forth moves back and forth.At present, eccentric shaft one end in the existing agricultural mowing machine all is provided with a flat key groove usually, during operation, drive motor only can be by this flat key groove to the eccentric shaft transmitting torque, in other words, the moment of torsion that drive motor is exported will all be applied on the flat key groove, in the course of time by flat key, fatigue fracture will take place because of the shearing force that is subjected to flat key for a long time in the flat key groove, and then shortens the working life of eccentric shaft.
The model utility content:
The technical problems to be solved in the utility model is that a kind of agricultural mowing machine eccentric shaft that can effectively increase the service life is provided.
Technical solution of the present utility model is that a kind of agricultural mowing machine eccentric shaft with following structure is provided: comprise the eccentric shaft body, wherein, eccentric shaft body one end is provided with a plurality of splines.
Agricultural mowing machine eccentric shaft described in the utility model, wherein, the quantity of spline can be 3～20.
Agricultural mowing machine eccentric shaft described in the utility model, wherein, the quantity of spline can be 3,6,10 or 15.
After adopting above structure, compared with prior art, the agricultural mowing machine of the utility model has the following advantages with eccentric shaft: only to be provided with a flat key groove different with prior art eccentric shaft one end, the agricultural mowing machine of the utility model has adopted a plurality of splines to replace a flat key groove with eccentric shaft one end, like this, the moment of torsion that drive motor is exported will be by mean allocation to a plurality of splines, in other words, the moment of torsion that each spline bore can be very little, correspondingly, the suffered shearing force of each spline also can reduce, and by this structure, the agricultural mowing machine of the utility model has effectively prolonged the working life of self with eccentric shaft.In addition, spline is compared with the flat key groove and can also be born bigger load.
Description of drawings:
Fig. 1 is the main TV structure schematic representation of the agricultural mowing machine of the utility model with eccentric shaft.
Embodiment:
Below in conjunction with the drawings and specific embodiments the agricultural mowing machine of the utility model is described in further detail with eccentric shaft:
As shown in Figure 1, in this embodiment, the agricultural mowing machine of the utility model comprises eccentric shaft body 1 with eccentric shaft, and eccentric shaft body 1 one ends are provided with 6 splines 2.
When the agricultural mowing machine of the utility model drives blade (not shown) on the agricultural mowing machine and back and forth moves back and forth by self eccentric shaft part with eccentric shaft, the moment of torsion that drive motor in the agricultural mowing machine is exported will be averaged distribution by 6 splines, in other words, the moment of torsion of drive motor output is born jointly by 6 splines, like this, the moment of torsion that each spline bore can be very little, correspondingly, the suffered shearing force of each spline also can reduce, by this structure, the agricultural mowing machine of the utility model has effectively prolonged the working life of self with eccentric shaft.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
Claims (3)
