Background technique
In agricultural machinery equipment, various gear-box can be used and carry out transferring power, and most of gear-box can not rotate towards a specific direction, general is all with power plant forward or reverse, or change sense of rotation by clutch, but in farm equipment, some place needs work package can only rotate towards a direction, such as, stubble cleaner, power is provided by tractor, and drive walking, operationally by screw type stubble-clearing device by the plant stubble in soil to cleaning out, this equipment only needs in working order, gear-box can drive stubble-clearing device to rotate towards a specific direction, do not need other too much useless rotations, because useless rotation meeting abrased gear case and stubble-clearing device, damage equipment, reduce working life.
Summary of the invention
The purpose of this utility model is to provide a kind of one-way output gear case that can only carry out specific direction rotation.
The purpose of this utility model is achieved in that a kind of one-way output gear case, comprise casing, input shaft and output shaft are installed in casing, input shaft arranges input gear, output shaft arranges output gear, output shaft is fixedly connected with output gear, wherein, described input shaft and output shaft are mutually vertical, and input gear and output gear engage each other, described input shaft is provided with shift fork flat key device, described input gear is socketed on shift fork flat key device, described shift fork flat key device comprises shift fork flat key and elastic component, both are installed in the keyway of input shaft setting, input shaft drives input gear to rotate, described shift fork flat key is needed to act on described input gear.
According to upper described a kind of one-way output gear case, wherein, described elastic component is fixed on one of them base angle of described keyway, one end of described shift fork flat key is articulated with another base angle, and described shift fork flat key covers described elastic component, described shift fork flat key can relatively described keyway, rotates among a small circle, is in keyway completely or part protrudes from outside keyway.
According to upper described a kind of one-way output gear case, wherein, described elastic component is compression spring, supports shift fork flat key and protrudes from outside keyway.
According to upper described a kind of one-way output gear case, wherein, described input gear and output gear are angular wheel, provide efficient and stable drive.
