Utility model content
The technical problem that the utility model solves is to provide that a kind of structure is simple, easy to adjust, the overload clutch that can not produce on the maize harvesting machine of strong vibration and sound.
The technical solution of the utility model completes like this, overload clutch on maize harvesting machine, it is characterized in that: include active friction disk, driven friction disk, left flange plate and right flange, active friction disk, driven friction disk, the centre of left flange plate and right flange is provided with the circular hole in same axle center, described active friction disk is fixed on the right side of left flange plate, the driven friction disk matched with active friction disk is fixed on the left of right flange, bulge loop on driven friction disk is located at the right side of driven friction disk, be rotationally connected with right flange in the flange hole that bulge loop is located on right flange, right flange is arranged on the driven friction disk of upper and lower on the left of bulge loop and blocks, left, right flange is bolted together, be located at cover on the bolt on the right side of right flange and have stage clip, the bolt be located on the right side of stage clip is provided with regulating nut.
Also include sprocket wheel, described sprocket wheel is fixedly connected with active friction disk, and the axle center of active friction disk is identical with the axle center of the sprocket hole of sprocket wheel.
Technique effect of the present utility model is; because the clutch safety matched with stage clip by existing ratchet transform the clutch safety matched with stage clip by frictional disk as; the concavo-convex friction of prior art is changed into of the present utility model to rub with face; the frictional force between left and right frictional disk can be adjusted easily, can available protecting corn snapping unit.During work, strong vibration and sound can not be produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of driven friction disk in Fig. 1.
Fig. 3 is the structural representation of right flange in Fig. 1.
Fig. 4 is prior art structural representation.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail.
Embodiment one: active friction disk 14, driven friction disk 13, left flange plate 7 and the middle circular hole being provided with same axle center of right flange 9, described active friction disk 14 is fixed on the right side of left flange plate 7, the driven friction disk 13 matched with active friction disk 14 is fixed on the left of right flange 9, bulge loop 12 on driven friction disk 13 is located on the right side of driven friction disk 13, bulge loop 12 to be located in flange hole on right flange 9 15 and to be rotationally connected with right flange 9, the driven friction disk 13 that right flange 9 is arranged on upper and lower on the left of bulge loop 12 blocks, left flange plate 7, right flange 9 is linked together by bolt 8, be located at cover on the bolt 8 on the right side of right flange 9 and have stage clip 10, the bolt 8 be located on the right side of stage clip 10 is provided with regulating nut 11.
Embodiment two: on the basis of embodiment one, also includes sprocket wheel 1, and described sprocket wheel 1 is fixedly connected with active friction disk 14, and the axle center of active friction disk 14 is identical with the axle center in the chain hole of sprocket wheel 1.
When the utility model is installed, sprocket wheel 1, active friction disk 14, driven friction disk 13, left flange plate 7 and right flange 9 are located at power transmission shaft one end, sprocket wheel 1, active friction disk 14, left flange plate 7 are connected with drive axis with right flange 9, and driven friction disk 13 is fixedly connected with power transmission shaft 6.For preventing bulge loop 12 displacement laterally in rotation, the power transmission shaft outside bulge loop is spirally connected hold-doun nut 5.
When work often works, active friction disk 7 and driven friction disk 9 compress mutually, and the frictional force produced between the two meets the normal kinetic demand of power transmission shaft or sprocket wheel.When power transmission shaft 6 is power take-off, when sprocket wheel 1 is power input wheel, when power transmission shaft 6 transships excessive, after the frictional force produced between active and passive frictional disk is less than the power demand required for power transmission shaft 6, sprocket wheel 1, left flange plate 7, active friction disk 14, right flange 9 rotate, and driven friction disk 13 follows power transmission shaft 6 to stop operating together.When power transmission shaft 6 is power input shaft, when sprocket wheel 1 is power output wheel, when sprocket wheel 1 transships excessive, after the frictional force produced between active and passive frictional disk is less than the power demand required for sprocket wheel 1, sprocket wheel 1, left flange plate 7, active friction disk 14, right flange 9 stop operating, and driven friction disk 13 follows power transmission shaft 6 to rotate together.So just effectively can prevent the relevant apparatus because damaging power transmission shaft or sprocket wheel and this power transmission shaft or chain wheel drive when power transmission shaft or sprocket wheel transship excessive.
When this clutch is arranged on reaping apparatus power take-off, power transmission shaft 6 is exactly reaping apparatus power take-off, sprocket wheel 1 is power input wheel, sprocket wheel 1 by active and passive frictional disk by transmission of power to reaping apparatus power take-off, power is provided to reaping apparatus again by reaping apparatus power take-off, when the overload of reaping apparatus is excessive, reaping apparatus quits work because not having enough power, just effectively can prevent the damage of reaping apparatus.When this clutch is arranged on corn snapping unit power input shaft, power transmission shaft 6 is corn snapping unit power input shaft, sprocket wheel 1 is corn snapping unit power output wheel, corn snapping unit power input shaft by active and passive frictional disk by transmission of power to sprocket wheel 1, power is provided to corn snapping unit again by sprocket wheel 1, when the overload of corn snapping unit is excessive, corn snapping unit quits work because not having enough power, just can have the damage preventing corn snapping unit.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, also should be considered as protection domain of the present utility model.
