Abstract
The utility model relates to a taper clutch for a farming machine. The taper clutch for the farming machine comprises a taper clutch outer cover (1), a taper clutch inner core (2), a reset spring (3) and a main shaft (4). The main shaft (4) is installed in a center hole of the taper clutch inner core (2), and the reset spring (3) is arranged on the main shaft (4) in a sleeved mode. The tapered face and the side face of the conical clutch outer cover (1) are provided with oil inlet holes (6), and the working tapered face of the taper clutch outer cover (1) and the working tapered face of the taper clutch inner core (2) are provided with carburization and nitridation coatings (5). According to the taper clutch for the farming machine, the oil inlet holes are formed in the tapered face and the side face of the taper clutch outer cover so that the tapered face can be fully lubricated in a semi-clutch state, and temperature rising, caused by friction, of the clutch is greatly relieved. In addition, the carburization and nitridation coatings with a certain thickness are arranged on the working tapered faces, and the service life of the taper clutch is prolonged by ten or more times compared with a common taper clutch.
Description
Technical field
The utility model relates to a kind of cone clutch, relates in particular to one and is applicable to agricultural ploughing machine, and can reduce clutch temp and rise and improve the clutch cone clutch in working life.
Background technique
As everyone knows, in agricultural ploughing machine, need to use clutch more and carefully to plough to realize slightly.But, the current cone clutch that is not applicable to agricultural ploughing machine.In agricultural ploughing machine, it is all at present the friction plate clutch that adopts motorcycle to use.But, thereby the complex structure of this friction plate clutch makes its cost high, and the total thickness of the monolithic work clutch-plate of friction plate clutch is only 2mm simultaneously, and therefore it very easily weares and teares, thereby makes its life-span shorter.
In addition, existing cone clutch does not arrange oil inlet hole, can not realize opening lubricated, and its tapering working surface is just through conventional Heat Treatment, thereby make tapering working surface temperature under half-clutch state sharply increase, thereby the Fast Wearing that has aggravated clutch tapering working surface, shortens the working life of clutch greatly.
Therefore, can be applicable to agricultural ploughing machine in the urgent need to one at present, and there is the clutch of long life.
Summary of the invention
The utility model is intended to solve the agricultural ploughing machine clutch short problem in working life of current existence.
For this reason, the utility model provides a kind of cone clutch for agricultural ploughing machine, comprise cone clutch outer cover (1), cone clutch inner core (2), Returnning spring (3) and main shaft (4), described main shaft (4) is contained in the center hole of described cone clutch inner core (2) and described Returnning spring (3) is sleeved on described main shaft (4), wherein, on the conical surface of described cone clutch outer cover (1) and side, all offer oil inlet hole (6), and on the work conical surface of described cone clutch outer cover (1) and described cone clutch inner core (2), all there is carbo-nitriding coating (5).
Further, on the conical surface of described cone clutch outer cover (1), offer on the side of six oil inlet holes (6) and described cone clutch outer cover (1) and offer four oil inlet holes (6).
The advantages such as that cone clutch described in the utility model has is simple in structure, cost is low, durable wear and long service life.
Brief description of the drawings
Fig. 1 is the front view of cone clutch of the present utility model.
Fig. 2 is the phantom of cone clutch outer cover of the present utility model.
Fig. 3 is the phantom of cone clutch inner core of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figures 2 and 3, the cone clutch for agricultural ploughing machine of the present utility model comprises cone clutch outer cover (1), cone clutch inner core (2), Returnning spring (3) and main shaft (4).As shown in Figure 3, described main shaft (4) is contained in the center hole of described cone clutch inner core (2) and described Returnning spring (3) is sleeved on described main shaft (4).On the conical surface of described cone clutch outer cover (1) and side, all offer oil inlet hole (6).On the work conical surface of described cone clutch outer cover (1) and described cone clutch inner core (2), all there is carbo-nitriding coating (5), due to the existence of carbo-nitriding coating (5), greatly improve the wear resistance of the clutch work conical surface, thereby greatly improved its working life.
As shown in Figure 1, on the conical surface of described cone clutch outer cover (1), offer six oil inlet holes (6), and on the side of described cone clutch outer cover (1), offer four oil inlet holes (6).Owing to offering oil inlet hole, thereby make the work conical surface can obtain sufficient lubrication at half-clutch state, and greatly reduce the clutch temp rising that friction causes.
While first cone clutch being used for to agricultural ploughing machine, clutch housing is connected on engine spindle and is screwed by six side's splined holes and kills, and clutch inner core is also placed on transmission main shaft by six side's splined shafts.Due to the existence of Returnning spring, between clutch inner core and clutch housing, rely on the tension force of Returnning spring and separate clutch housing idle running.In the time that needs microtilling machine is worked, by shift fork, clutch inner core is pressed to clutch housing, make the work conical surface laminating between them, thereby clutch housing band dynamic clutch inner core is rotated, last clutch inner core drives main shaft rotary work by six side's splines.
Thereby cone clutch described in the utility model its cost that makes simple in structure is lower, and reach 5mm above (total thickness of the monolithic work clutch-plate of friction plate clutch is only 2mm) due to its operation thickness thus make its durable wear, therefore life more than 10 times, need not be changed all the life.In addition, by oil inlet hole being set on the conical surface at cone clutch outer cover and side, make the conical surface can obtain sufficient lubrication at half-clutch state, and greatly reduce the clutch temp rising that friction causes; Meanwhile, by the work conical surface, certain thickness carbo-nitriding layer being set, greatly improved its wear resistance, thereby greatly improved its working life.
The content of embodiment is understood for the ease of those skilled in the art and is used the utility model and describing, and does not form the restriction to the utility model protection content.Those skilled in the art, after having read content of the present utility model, can carry out suitable amendment to the utility model.Protection content of the present utility model is as the criterion with the content of claim.In the case of the flesh and blood and protection domain that do not depart from claim, various amendments, change and replacement etc. that the utility model is carried out are all within protection domain of the present utility model.
