Abstract
The utility model relates to a harvester clutch which is composed of a cover 1, a pressure plate 2, a diaphragm spring 3, a friction sheet 4, a damping spring 5 and a spline hub 6, wherein the pressure plate 2 and the diaphragm spring 3 are riveted on the cover 1, and the friction sheet 4 is positioned between a power wheel and the pressure plate 2; an installing steel sheet of the friction sheet 4 is radially contacted with the damping spring 5, and the spline hub 6 is positioned in the damping spring 5. The utility model is characterized in that the thickness of the diaphragm spring 3 is between 2.8 and 3.0 millimeters, and the outer diameter of the friction sheet 4 is between 235 and 242 millimeters. Pressure more than 5000 N is generated, and torque which is conveyed by generated friction force reaches 300 N/M in limited space so that the utility model meets the requirements of the conveyance and the switching of the walking power of a harvester D 2.8, and the versatility of relevant parts of the clutch is furthest guaranteed. The cost of manufacture of the harvester D 2.8 is reduced.
Description
Technical field
The utility model is applicable to the transmission and the switching of novel D2.8 grain header walking power.
Background technology
The D2.8 grain header is a kind of novel harvester, and a lot of parts are to adopt society to go up existing D2 grain header parts, original its thrust of D2 grain header clutch 4000N, moment of torsion 240N.M, thrust and moment of torsion are too little, can not satisfy the transmission of D2.8 grain header walking power and the needs of switching, therefore require in the space of limiting to very much, to design D2.8 grain header clutch, can satisfy the transmission of D2.8 grain header walking power and the needs of switching, guarantee the versatility of the correlated parts of clutch again to greatest extent.And the direction of rotation of D2.8 grain header clutch is clockwise, and is opposite with the direction of rotation of automobile clutch.So can't adopt any automobile clutch.Therefore must a kind of novel D2.8 grain header clutch of design.
Summary of the invention
The purpose of this utility model is to provide a kind of grain header clutch, can satisfy the transmission of D2.8 grain header walking power and the needs of switching, guarantees the versatility of the correlated parts of clutch again to greatest extent.
The technical scheme that its technical problem that solves the utility model adopts is: the grain header clutch, it covers 1, platen 2, diaphragm spring 3, friction plate 4, damping spring 5, splined hub 6, platen 2 and diaphragm spring 3 are riveted on and cover on 1, friction plate 4 between power wheel and platen 2, the installation steel disc of friction plate 4 is radially contacting with damping spring 5, be splined hub 6 in the damping spring 5, it is characterized in that: the thickness of diaphragm spring 3 is 2.8-3.0 rice, and the external diameter of friction plate 4 is the 235-242 millimeter.
Aforesaid grain header clutch is characterized in that: described clutch installation dimension: 6 (hole count)-M8 (screw size) are distributed in φ 273mm, and the splined hub matching spline is 10 (keyway number)-5.4mm (keyway is wide).
Beneficial effect
Diaphragm spring be pressure elements be again resolution element, make clutch configuration very succinct, the separating effect of clutch is also fine; Between friction plate and splined hub, add damping spring, make when transmitting moment of torsion comparatively smooth-going.
The beneficial effects of the utility model are, in the space of unusual limitation, can satisfy the transmission of D2.8 grain header walking power and the needs of switching, guarantee the versatility of the correlated parts of clutch again to greatest extent.Because simple for structure, greatly reduce the rotary inertia of clutch, the shake of the grain header gearbox power shaft that reduces to know clearly.
By a large amount of experiments, adopt above-mentioned parameter, can produce the above pressure of 5000N, this pressure acts on frictional force that friction plate produces and can transmit moment of torsion and reach more than the 300N.M, satisfies the transmission of D2.8 grain header walking power and the needs of switching fully.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.Wherein, 1 lid, 2 platens, 3 diaphragm springs, 4 friction plates, 5 damping springs, 6 splined hub.
Embodiment
See Fig. 1, be locked on the drive pulley 10 with the stamping forming lid 1 of 4mm steel plate, installation dimension: 6-M8 is distributed in φ 273mm, platen 2 and diaphragm spring 3 be riveted on cover on 1, the pressure that is added on the platen 2 by diaphragm spring 3 acts on the friction plate 4, produce frictional force and transmit moment of torsion, friction plate 4A and 4B riveting are contained in installs on the steel disc 4C, steel disc 4C is installed then lenitively moment of torsion is passed to splined hub 6 by damping spring 5, splined hub 6 passes to the input splined shaft 8 of gearbox 9 again, finishes transmission of power.The matching spline 8 of splined hub 6 for 10-5.4mm. when release bearing 7 is depressed diaphragm spring 3 and is removed its thrust, then finish powershift.
The thickness of diaphragm spring 3 is preferably 2.9 millimeters, and the external diameter of friction plate 4 is preferably 240 millimeters.Can produce the pressure of 5000N, this pressure acts on frictional force that friction plate produces and can transmit moment of torsion and reach 300N.M, in the space of limiting to very much, can satisfy the transmission of D2.8 grain header walking power and the needs of switching, guarantee the versatility of the correlated parts of clutch again to greatest extent.
