The utility model is that with the fan clutch difference from prior art of damping device the utility model is embedded the bumper and absorbing shock layer with the fan clutch of damping device in pto＝power take-off and driving disc that the fan clutch transmission shaft is connected, when pto＝power take-off drive fan clutch moment startup driving torque is larger, be embedded the bumper and absorbing shock layer generation resiliently deformable in driving disc, the impact force that buffering moment startup brings, reduced the impact of impact force to power take-off (such as motor) and fan clutch, improve the working life of the two, also reduced the noise of equipment operation.
Below in conjunction with accompanying drawing the fan clutch with damping device of the present utility model is described further.
Description of drawings
Fig. 1 is that the utility model is with the sectional view of the fan clutch of damping device.
Embodiment
As shown in Figure 1, the utility model comprises transmission shaft 1 with the fan clutch of damping device, and its end is connected with driving disc 2.The second joint 22 that driving disc 2 comprises the first joint 21 of being made by aluminium, made by iron material and between first and second joint and coupled logical bumper and absorbing shock layer 23, bumper and absorbing shock layer 23 adopts rubber material to make, the excircle of the first joint 21 radially outwards is provided with extension part 211, driving disc 2 is affixed by extension part 211 and pto＝power take-off 17, and the second joint 22 is connected with transmission shaft 1 key.
The utility model is all applicable for a speed, two speed, three speed fan clutch with the fan clutch of damping device, provides especially a kind of interior drive-type two speed fan clutch structures at this, and is specific as follows:
Be arranged with drive plate 3, magnet fixed disc 5 and fan fixed disk 6 on the transmission shaft 1, be provided with the first axle sleeve 13 between drive plate 3 and the transmission shaft 1, drive plate 3 is welded on the first axle sleeve 13, and the first axle sleeve 13 is connected on the transmission shaft 1 by key, makes drive plate 3 with transmission shaft 1 rotation.Be embedded with electromagnetic core 7 in the drive plate 32, be provided with coil 8 in the electromagnetic core 7, be provided with adhesive dish 4 between drive plate 3 and the magnet fixed disc 5, adhesive dish 4 is corresponding with coil 8, and adhesive dish 4 is fixedly connected with spring sheet 9, spring sheet 9 affixed fan fixed disk 6.
Magnet fixed disc 5 is arranged in the inner chamber of fan fixed disk 6, circumferentially is provided with permanent magnet 10 on the magnet fixed disc 5, is provided with magnetic conduction ironware 11 with permanent magnet 10 corresponding sections in the fan fixed disk 6.
Magnet fixed disc 5 will keep and transmission shaft 1 synchronized running, can be by variety of ways such as key connections, present embodiment adopts and between magnet fixed disc 5 and transmission shaft 1 fixed cover 12 is set, the outer wall of fixed cover 12 and magnet fixed disc 5 drive fits, transmission shaft 1 is combined with nut 14 near the end of fan fixed disk 6, by fastening nut 14, the fan fixed disk bearing 15 that is enclosed within on the transmission shaft 1 and the second axle sleeve 16, fixed cover 12 head and the tail are offseted, with fixed cover 12 axial compression on the first axle sleeve 13, so that magnet fixed disc 5 is with transmission shaft 1 rotation.So arrange, can replace easily on three speed clutch of prior art, fixed cover in the position direct replacement of former magnet fixed disc bearing is got final product, compatibility is strong.
