Abstract
The utility model discloses a tractor rear power output safety clutch. A hollow combination shaft is arranged in a shell; a friction plate and a transfer plate are sequentially arranged between the peripheral wall of the combination shaft and the inner wall of the shell at an interval; a key slot is formed in the axial inner circumferential wall of the combination shaft; a gland, disc springs, an inner clamp sleeve, a spring, an outer clamp sleeve and an outer end cover are arranged on the peripheral wall on the other side of the combination shaft sequentially from inside to outside; a stop steel ball is arranged on the wall of the combination shaft in the outer clamp sleeve; two disc springs are provided; a compression bolt is horizontally arranged on the gland; the two disc springs are compressed by the compression bolt. After being inserted into the combination shaft, the power output shaft is clamped by the stop steel ball; after the power output shaft experiences overload of the agricultural machinery, the overload is transferred to the transfer plate through a spline structure on the outer surface and a spline structure on the inner surface of the combination shaft; if the overload exceeds the compression force on the compression bolt, the transfer plate and the friction plate slide relatively, and the combination shaft and the power output shell are disconnected through transmission.
Description
Technical field
The utility model relates to power output safety clutch after a kind of tractor being applied on tractor.
Background technique
After the conventional clutch of installing on tractor breaks down in back axle, need to open back axle casing adjusts and safeguards, cannot be by suitable its safe coefficient of connection of modulation of actual agricultural machinery and implement state of cultivation in actual using process, cannot avoid the agricultural machinery and implement to occur the problem that causes serious transmission component to break after agricultural machinery and implement overload in the situation that there is no safety clutch.
Summary of the invention
The purpose of this utility model is to provide power output safety clutch after a kind of tractor, while there is traffic overload situation in agricultural machinery and implement working procedure, can disconnect in time transmission, prevents that agricultural machinery and implement transmission part from damaging.
The purpose of this utility model is to realize like this, power output safety clutch after a kind of tractor, comprise shell, the combined axis of hollow is being set in shell, between combined axis periphery wall and outer casing inner wall, interval is being set with friction plate and is transmitting sheet successively, on the axial inner circle wall of combined axis, keyway is being set, on the opposite side periphery wall of combined axis, setting gradually from inside to outside gland, dish spring, interior cutting ferrule, spring, outer cutting ferrule and outer end cap, wherein on the combination axial wall in outer cutting ferrule, a stop steel ball is being set, dish spring is two, on gland, be horizontally disposed with hold-down bolt, two dish springs compress by hold-down bolt.
Adopt after such structure, in combined axis, insert after pto＝power take-off, the axle that outputs power under the effect of spring with stop steel ball blocks, after pto＝power take-off is subject to agricultural machinery and implement overload load, by the spline structure of outer surface and the spline structure of combined axis internal surface, be delivered in while transmitting on sheet, if while having surpassed the impacting force on hold-down bolt, transmit between sheet and friction plate relative sliding has occurred, make combined axis and power output shell realize the function that transmission disconnects.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
Embodiment
Power output safety clutch after a kind of tractor, as shown in Figure 1, comprise shell 1, the interior combined axis 3 that hollow is being set of shell 1, between combined axis 3 periphery walls and outer casing inner wall, interval is being set with friction plate 2 successively, 4, 8 and transmit sheet 5, 6, 7, 9, on the axial inner circle wall of combined axis 3, keyway is being set, on the opposite side periphery wall of combined axis 3, setting gradually from inside to outside gland 10, dish spring 12, 11, interior cutting ferrule 17, spring 16, outer cutting ferrule 15 and outer end cap 14, wherein on the combination axial wall in outer cutting ferrule, a stop steel ball 13 is being set, dish spring 12, 11 is two, on gland 10, be horizontally disposed with hold-down bolt 9, two dish springs 12, 11 compress by hold-down bolt 9.
