Technical field
The utility model relates to a kind of clutch.
Background technique
Existing a kind of clutch that is applied to corn harvester, it contains belt wheel, bonnet, left friction plate assembly, right friction plate assembly, center platen, platen, spring and separating mechanism.Belt wheel is interior hollow structure, and an end of belt wheel is provided with end face, the other end is uncovered.Bonnet is arranged on belt wheel uncovered, and left friction plate assembly, center platen, right friction plate assembly and platen are arranged in order between the end face of bonnet and belt wheel, and spring is between the end face of platen and belt wheel.Pull bar, separator levers and separator levers seat are contained in its disengagement mechanism, the separator levers seat is arranged on the outside of belt wheel end face, separator levers is contained on the separator levers seat, one end of pull bar passes the through hole that the belt wheel end face is provided with and links to each other with platen, and an end of the other end of pull bar and separator levers constitutes and flexibly connects.During use, motor arrives transmission of power by belt the belt wheel of above-mentioned clutch, because the spring in the belt wheel presses platen, platen is moved to the rear end of belt wheel, thereby left friction plate assembly, center platen, right friction plate assembly and platen are forced together tightly, under the frictional force effect, the splined shaft that at this moment is installed in the splined hole that left friction plate assembly and right friction plate assembly central authorities are provided with is given gearbox with transmission of power.When needs cut off the power transmission, may depress separator levers on the belt wheel by shift fork, elastic force that platen overcomes spring is moved to the end face of belt wheel, at this moment produce the gap between left friction plate assembly and bonnet and the center platen, produce the gap between right friction plate assembly and center platen and the platen, thereby realize the cut-out of power.Be helical spring at spring described in the above-mentioned clutch, in order to improve the transmission moment of torsion, usually the method that adopts is to increase helical spring elastic force, because the increase of helical spring elastic force, according to helical spring characteristic, the strength of pressing to shift fork is also improving, thereby the strength that causes spurring the operating handle of shift fork becomes big, even draw motionless, poor reliability.Because left friction plate assembly and right friction plate assembly do not have damping performance, therefore bigger in the initial time impulsive load of transferring power, the phenomenon of breaking gearbox gear takes place often.In above-mentioned clutch, because constituting, an end of the other end of pull bar and separator levers flexibly connects, cause bigger abnormal sound because of loosening, thereby cause noise pollution.
The model utility content
Technical problem to be solved in the utility model provides a kind of clutch, this clutch not only can reduce impulsive load at the initial time of transferring power, the phenomenon of avoiding breaking gearbox gear takes place, and suit at power and to keep reliability preferably in the process, can avoid the generation of abnormal sound phenomenon simultaneously.
For solving the problems of the technologies described above, a kind of clutch of the utility model, contain belt wheel, bonnet, left side friction plate assembly, right friction plate assembly, center platen, platen, spring and separating mechanism, belt wheel is interior hollow structure, one end of belt wheel is provided with end face, the other end is uncovered, bonnet is arranged on belt wheel uncovered, left friction plate assembly between the end face of bonnet and belt wheel, center platen, right friction plate assembly and platen are arranged in order, spring is between the end face of platen and belt wheel, separating mechanism contains pull bar, separator levers and separator levers seat, the separator levers seat is arranged on the outside of belt wheel end face, separator levers is installed on the separator levers seat by bearing pin, one end of pull bar passes the through hole that the belt wheel end face is provided with and links to each other with platen, one end of the other end of pull bar and separator levers constitutes flexible connection, also contains torsion spring, and this torsion spring is arranged on the described separator levers seat, the torsion bar of this torsion spring is pressed on the other end of separator levers, makes an end of separator levers be close to the other end of described pull bar; Described left friction plate assembly contains friction plate, intermediate plate, driven disc, damping disk(-isc), shock-absorbing spring, dish hub and damping washer, friction plate is arranged on the intermediate plate, intermediate plate is arranged on the driven disc, be connected and fixed by position limit pin between driven disc and the damping disk(-isc), the dish hub is installed between driven disc center hole and the damping disk(-isc) center hole, shock-absorbing spring is contained between the fenestra that driven disc and damping disk(-isc) be provided with, and shock-absorbing spring is positioned at the through hole that the dish hub is provided with, damping washer is contained in the both sides of dish hub, the central authorities of dish hub are provided with splined hole, the structure of described right friction plate assembly is identical with the structure of left friction plate assembly, and described spring is belleville spring.
In above-mentioned clutch, because left friction plate assembly and right friction plate assembly have adopted shock-absorbing spring, make the load impacting of the initial time of transferring power obtain buffering, the phenomenon of therefore avoiding breaking gearbox gear takes place; Because the spring between platen and the belt wheel end face adopts belleville spring, characteristic according to belleville spring, practice shows, transmit moment of torsion and increase by 20%, and the strength of the operating handle of pulling shift fork reduces 50%, overcome prior art and drawn the deficiency of motionless operating handle, poor reliability, thereby made power in suiting process, keep reliability preferably; Owing at described separator levers seat torsion spring is set, the torsion bar of this torsion spring is pressed on the other end of separator levers, and an end that makes separator levers is close to the other end of described pull bar, has therefore overcome prior art because of the loosening generation that causes big abnormal sound phenomenon, has avoided noise pollution.
