Abstract
The invention relates to an overload protection diverter used for power transmission of a harvester and belongs to the technical field of converters. The overload protection diverter comprises a box body. A shaft is transversely installed in the box body. The shaft is provided with a conical tooth through a third bearing. A bevel gear shaft engaged with the conical tooth is longitudinally installed in the box body. The part, on the left side of the conical tooth, of the shaft is sleeved with a nut in threaded connection, and a first clutch used for power transmission of the shaft is installed on the part, on the right side of the nut, of the shaft. The part, between the first clutch and the nut, of the shaft is sleeved with a spring. The left end of the spring abuts against the nut, and the right end of the spring abuts against the first clutch. The part, on the right side of the first clutch, of the shaft is provided with a second clutch which can rotate freely around the shaft. The second clutch is connected with the first clutch through a clutch jaw in a matched manner. The second clutch and the shaft are transversely positioned through internally-contained balls. The left end of the conical tooth is connected to the second clutch through a spline. The overload protection diverter is simple in structure, the stress contact area is large, transmission is more stable, and overload protection is achieved.

Of the present invention for the powerdriven overload protection commutator of reaper, comprise casing, axle is horizontally installed with in casing, axle left end is arranged on the left wall of casing by clutch shaft bearing, axle right-hand member is arranged on the right wall of casing by the second bearing, axle is provided with cone tooth by the 3rd bearing, corresponding cone tooth is longitudinally provided with and the bevel gear shaft of boring tooth and being meshed in casing, the umbrella increment of bevel gear shaft is meshed with cone tooth, the shaft portion of bevel gear shaft is arranged on casing by the 4th bearing, it is characterized in that: on the axle on the left of cone tooth, cover has the nut be threaded, axle on the right side of nut is provided with for the powerdriven clutch one of axle, on axle between clutch one and nut, cover has spring, spring left end withstands on nut, its right-hand member withstands on clutch one, axle on the right side of clutch one is provided with the clutch two that freely can rotate around axle, clutch two is connected by clutch claw and clutch one, clutch two carries out located lateral by intension ball and axle, cone tooth left end by spline joint on clutch two.
Conveniently process, conservative control cost, what preferred described cone tooth was arranged is external splines, and what clutch two was arranged is internal spline.
In the present invention, clutch one is provided with the following two kinds mode with coordinating of axle:
One, described clutch one is that spline fitted is installed with axle.
Two, described clutch one and axle are that flat key coordinates and installs.
Clutch in order to ensure spring coordinates dynamics, and the natural length of preferred described spring is 100mm ~ 300mm.
Compared with prior art, the present invention has following beneficial effect:
By of the present invention for the powerdriven overload protection commutator of reaper; its structure is simple; forced contact area is large; transmission is more steady; achieve overload protection, avoid when the power exported is obstructed, because input shaft continues at Input Forces; thus the phenomenon causing commutator internal transmission part to damage occurs, and reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, casing 2, clutch shaft bearing 3, axle 4, nut 5, spring 6, clutch 1, clutch 28, the 3rd bearing 9, cone tooth 10, second bearing 11, bevel gear shaft 12, the 4th bearing 13, ball.
