For solving the problems of the technologies described above, the technical solution of the utility model is: double-velocity transmission comprises gearbox casing; Power input shaft, described power input shaft rotates and is installed on the described gearbox casing, is installed with first gear on the described power input shaft; Pto, described pto rotates and is installed on the described gearbox casing, is installed with second gear on the described pto; Described double-velocity transmission also comprises transition axis, described transition axis rotates and is installed on the described gearbox casing, described transition axis is provided with the deceleration duplicate gear that meshes simultaneously with described first gear and second gear, and described deceleration duplicate gear drives lower slider at power plant and is installed on the described transition axis; Be used for the transmission of power of the described power input shaft clutch to the described pto, described clutch is arranged between described power input shaft and the pto.
As a kind of improvement, described power input shaft and pto are coaxially installed on the described gearbox casing, and an end of described power input shaft is set in an end of described pto.
As further improvement, described transition axis is provided with spline, and described deceleration duplicate gear is provided with and the suitable spline tooth of described spline.
As further improvement, be provided with the gear pump that is used for lubricated described first gear and second gear in the described gearbox casing, the housing of described gear pump is fixedly installed on the described gearbox casing, and the line shaft of described gear pump connects with described transition axis.
As a kind of improvement, described power plant comprise the hydraulic jack that is installed on the described gearbox casing, on the piston rod of fast hydraulic jack fixed installation be useful on the shift fork that drives described deceleration duplicate gear.
Improve as another kind, described clutch is a magnetic clutch.
After having adopted technique scheme, the beneficial effects of the utility model are: because the power input shaft of gearbox can either be connected by the deceleration duplicate gear with pto, can throw off the deceleration duplicate gear again connects by clutch, therefore can realize the double speed conversion easily, when low speed, power input shaft and pto are by the engagement of deceleration duplicate gear, realize too moment of torsion slow cutting, when high speed, power input shaft and pto connect by clutch, realize permanent power output, during owing to high speed, the deceleration duplicate gear is thrown off, make in the whole transmission process, do not have gear to participate in,, improved the performance of lathe greatly so there is not the transmission noise.
Because power input shaft and the coaxial installation of pto make and the gearbox designs compactness can conveniently realize clutch transmission, transmission efficiency height during high speed.
Owing in the gearbox gear pump is installed, the line shaft and the transition axis of gear pump are linked together, when the low speed gear transmission, transition axis rotates with angular velocity by spline transmission and deceleration duplicate gear, by the direct driving gear pump of transition axis gear is carried out pressure lubrication, transmission noise when making low speed is slackened, and has improved the working life of driving gear simultaneously.
