The double-headed spline shaft has a simple structure, the compactness of the whole structure of a power conversion device can be improved, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of transmission shaft, particularly a kind of double end splined shaft of switchover apparatus.
Background technique
It is that spline connects the axial of axle that the available dynamic conversion equipment adopts the structure of splined shaft usually, the stage casing of this splined shaft is used for spline fitted one clutch gear, the two ends shaft part of splined shaft is respectively applied for one in each empty cover can be with respect to the gear of splined shaft rotation, clutch gear on the splined shaft stage casing moves, can with a gear engagement transferring power on the shaft part of splined shaft two ends, power is passed to splined shaft output from gear through clutch gear.Adopt the power switching device of this splined shaft that another parallel and bridge gear shaft splined shaft also must be set, the power that power source is transmitted passes to the overhead gear that overlaps of spline through the carrier gear axle, pass to splined shaft output by this gear through clutch gear again, the complex structure that causes power switching device thus, volume increases, and fabricating cost increases.And this splined shaft generally is to be used for by power-converting between the dislocation parallel axes, the conversion of its power is the variation that makes the sense of rotation of splined shaft output torque turn clockwise or be rotated counterclockwise, if the moment of torsion of power switching device transmission keeps same sense of rotation, and between two outputting power spares, switch, existing splined shaft just can not have been realized.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, a kind of double end splined shaft of switchover apparatus is provided, it can cooperate with another axle of coaxial inner conductor, the powershift that realization is transmitted with the rotation direction moment of torsion, it is simple in structure, can improve the integrally-built compactedness of power switching device, reduce fabricating cost.
The technical solution of the utility model is: a kind of double end splined shaft of switchover apparatus, the axis body that the double end splined shaft is structure as a whole, the middle part of axis body is provided with limited step, described limited step is separated into the first identical shaft part of diameter and second shaft part with axis body, the circumference of described first shaft part is provided with first outer spline section, the end of first shaft part is provided with the smooth axle journal of diameter less than first outer spline section, described second shaft part comprises the smooth section and second outer spline section, and smooth section is between the limited step and second spline segment.
The length of described first shaft part is greater than the length of second shaft part.
The end of second shaft part of described double end splined shaft is provided with the threaded journal of diameter less than second shaft part.
Adopt technique scheme: because the axis body that the double end splined shaft is structure as a whole, the middle part of axis body is provided with limited step, and this double end splined shaft can be cooperated in the bearing cap that is supported in power switching device with bearing by limited step.Described limited step is separated into the first identical shaft part of diameter and second shaft part with axis body, wherein the circumference of first shaft part is provided with first outer spline section, be used to install synchronous conversion gear, make synchronous conversion gear can move axially the ground spline fitted on first shaft part, and the end of first shaft part is provided with the smooth axle journal of diameter less than first outer spline section, this double end splined shaft can be cooperated with the output shaft of coaxial inner conductor by smooth axle journal, realize the powershift that transmits with the rotation direction moment of torsion; Second shaft part comprises the smooth section and second outer spline section, smooth section is between the limited step and second spline segment, this double end splined shaft can be connected with power source by second outer spline section, cooperate with bearing by smooth section simultaneously second shaft part can be supported in the bearing cap of power switching device.Because this double end spline shaft structure is simple, can improve the integrally-built compactedness of power switching device, has greatly dwindled the volume of power switching device, has reduced fabricating cost.
