Abstract
The utility model discloses a steering clutch for a harvester, which comprises a transmission case and a transmission case output shaft arranged on the transmission case through a bearing. A first output shaft and a second output shaft opposite to each other are respectively arranged at left and right ends of the transmission case output shaft. A steel ball type clutch mechanism is arranged among the transmission case output shaft as well as the first output shaft and the second output shaft. The surface contact is replaced by the point contact when the steel ball clutch but not the jaw clutch is used for transferring torque. When in disconnection, the smaller force is used, thereby preventing unavailable disconnection in case of too much load. Therefore, the harvester with the structure has the steering function and simple and flexible steering operation.
Description
Technical field
The utility model relates to a kind of farm machinery, especially relates to a kind ofly can realizing that grain header that grain header turns to is with turning to arrangement of clutch.
Background technology
Grain header is a kind of straw of gathering in crops such as paddy and wheat, and it is sent into the machinery that threshing bin breaks away from.The Running System of existing grain header generally is such, is about to a steering spindle, should be two spline semiaxis; The two ends of semiaxis add shoe brake respectively; Turn to clutch gear with two, change the clutch gear that turns to of spline housing into; Two spline semiaxis respectively join by a copper sheathing and central driver gear.The stress condition of spline semiaxis of the prior art is poor, causes fast, the easy oil leakage of spline axle-shaft oil seal inefficacy, and the copper sheathing quick abrasion that spline semiaxis and central driver gear join causes turning to malfunctioning automatically.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of simple in structure, use the grain header reliable, that operation is light with turning to arrangement of clutch.
The technical solution of the utility model is as follows: the grain header of design is with turning to arrangement of clutch, comprises transmission case body and is installed in transmission case output shaft on this transmission case body through bearing, and its main points are:
A, be fixed with first clutch output cover and second clutch output cover respectively at described transmission case body two ends, two ends, the described transmission case output shaft left and right sides pass described transmission case body and stretch into described first clutch respectively and export in cover and second clutch output cover, respectively over against being provided with first output shaft and second output shaft, this first output shaft and second output shaft stretch out respectively outside described first clutch output cover and second clutch output cover at two ends, the described transmission case output shaft left and right sides;
B, be installed with the first steel ball clutch driving tooth overcoat at described transmission case output shaft left part, outside this first steel ball clutch driving tooth, put and be hinged with the first steel ball clutch yoke that described first clutch output cover is stretched out in the outer end, it is recessed that the right part of described first output shaft has the first steel ball arc, kink has the first steel ball cover on first output shaft outside this first steel ball arc is recessed, and on this first output shaft, be set with first the compression spring, this first compression spring, one end is against on first baffle plate that is provided with on described first output shaft, the other end is against described first steel ball and puts, outside the described first steel ball clutch driving tooth, put and have and the recessed first relative steel ball hole of the described first steel ball arc, be provided with first steel ball at the described first steel ball arc in recessed and first steel ball hole, described first steel ball cover right part is sleeved on outside the described first steel ball clutch driving tooth overcoat;
C, be installed with the second steel ball clutch driving tooth overcoat at described transmission case output shaft right part, outside this second steel ball clutch driving tooth, put and be hinged with the second steel ball clutch yoke that described second clutch output cover is stretched out in the outer end, it is recessed that the left part of described second output shaft has the second steel ball arc, kink has the second steel ball cover on second output shaft outside this second steel ball arc is recessed, and on this second output shaft, be set with second the compression spring, this second compression spring, one end is against on the second baffle that is provided with on described second output shaft, the other end is against described second steel ball and puts, outside the described second steel ball clutch driving tooth, put and have and the recessed second relative steel ball hole of the described second steel ball arc, be provided with second steel ball at the described second steel ball arc in recessed and second steel ball hole, described second steel ball cover left part is sleeved on outside the described second steel ball clutch driving tooth overcoat.
The utility model designs on the transmission grain header turns to bases such as the arrangement of clutch transmission is unreliable, in the above structure, the transmission case output shaft outputs power, stir the first steel ball clutch yoke and the second steel ball clutch yoke, make respectively the first steel ball cover move right and the second steel ball cover be moved to the left, make this first steel ball cover and the second steel ball cover be set in the first steel ball clutch driving tooth overcoat and the second steel ball clutch driving tooth overcoat, thereby first steel ball is limited in recessed and first steel ball hole of the first steel ball arc, second steel ball is limited in recessed and second steel ball hole of the second steel ball arc, so realization transmission case output shaft is connected with described first output shaft and second output shaft, output power at last, thus the walking of realization grain header; When the needs grain header turns to, stir the first steel ball clutch yoke, first steel ball is deviate from recessed and first steel ball hole from the first steel ball arc, make transmission case output shaft and described first output shaft throw off, thereby realize the left-hand rotation of grain header, in like manner can realize the right-hand rotation of gathering in.Be provided with in the above structure first the compression spring and second the compression spring be for make the first steel ball cover move right and the second steel ball cover can reset, adopt this kind steel ball clutch mode, when transmitting moment of torsion, be the some contact, replaced the face contact of castellated clutch, when breaking away from, firmly littler, take off too busy to get away phenomenon when big thereby avoid loading.So grain header adopts this structure to possess the function of turning to, and steering operation is light, flexible.
Put in described first clutch output and to have the first shift fork notch, be fixed with the first fork seat putting near first clutch of this first shift fork notch output, the described first shift fork notch is stretched out in the described first steel ball clutch yoke, this first steel ball clutch yoke middle part is sold with the described first fork seat and is connected, and it is more reliable that above structure can make grain header turn to when work.
Put in described second clutch output and to have the second shift fork notch, be fixed with the second fork seat putting near second clutch of this second shift fork notch output, the described second shift fork notch is stretched out in the described second steel ball clutch yoke, this second steel ball clutch yoke middle part is sold with the described second fork seat and is connected, and it is more reliable that above structure can make grain header turn to when work.
Beneficial effect: be the some contact when the utility model transmits moment of torsion, replaced the face contact of castellated clutch, when breaking away from, firmly littler, thereby avoiding loading takes off too busy to get away phenomenon when big and possesses the function of turning to, have steering operation light, flexible, be skillfully constructed, simple in structure, implement characteristics such as easy, reliable.
