Description

Centrifugal clutch

The utility model relates to a kind of centrifugal clutch, the clutch that especially a kind of member is few, structure is comparatively practical.

Present known clutch is of a great variety, and its structure is all quite complicated, and member is quite a lot of, and therefore operation becomes and quite bothers, and in use also is easy to generate many defectives, and spoilage is quite high, and all are used the people of clutch is suitable trouble.

The purpose of this utility model is that a kind of centrifugal clutch will be provided, especially a kind of easy to operate, member is few, well behaved clutch.

The purpose of this utility model is achieved in that a kind of centrifugal clutch, it mainly comprises connection one drive motor, this drive motor is used to drive a rotating shaft, and being concaved with a screw at the side of rotating shaft, a bolt passes respectively and screws togather after the gear that is pivoted, bearing and C type are buckled to the other screw of drive motor again.The rotating shaft of above-mentioned drive motor wears respectively into pad, sleeve, spring, on rotating disk and the inertia rotating disk, and each is provided with several concave arc grooves relatively at the opposing side of rotating disk and inertia rotating disk, this concave arc groove is the shallow grooves in middle dark both sides, set concave arc groove purpose is to be used for ccontaining steel ball, and this rotating disk inwardly is provided with tooth portion again, the inertia rotating disk wears into an electromagnet and a bearing again in addition, this electromagnet is provided with two holes and is provided with a cover cap in addition, this cover cap is convexly equipped with a cylinder in all members are placed in, and being provided with lockhole on the cover cap can by means of screw with cover cap locking on drive motor, and also be provided with two holes on the cover cap for utilizing two-screw, and with the electromagnet locking on cover cap.

The advantage of the centrifugal clutch that the utility model proposes is:

1. its structure does not resemble the complexity the known clutch, so it can reduce on cost significantly.

2. because it is simple in structure, also be quite convenient in the use therefore, do not resemble known clutch and in operation, bother so.

3. because the clutch that the utility model proposes need only just can reach the function of separating rotating disk and inertia rotating disk with the energising of electromagnet moment appropriate time, quite has practicability.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the perspective exploded view according to the centrifugal clutch that the utility model proposes;

Fig. 2 is the sectional drawing of the rotating disk according to the centrifugal clutch that the utility model proposes when not combining with gear as yet;

Fig. 3 is the steel ball position view of the rotating disk according to the centrifugal clutch that the utility model proposes when not combining with gear as yet;

Fig. 4 is according to the rotating disk of the centrifugal clutch that the utility model proposes and generalized section after gear combines;

Fig. 5 is the steel ball position view during according to the rotating disk of the centrifugal clutch that the utility model proposes and gear.

Below in conjunction with accompanying drawing and most preferred embodiment thereof the concrete structure that the utility model proposes is further described.

As shown in Figure 1, 2, described centrifugal clutch comprises connection one drive motor 10, this drive motor 10 is used to drive a rotating shaft 11, and be concaved with a screw 12, one bolts 43 at the side of rotating shaft 11 and pass be pivoted a gear 40, bearing 41 and C type respectively and buckle and screw togather again after 42 in the screw 12 other to drive motor 10.The rotating shaft 11 of drive motor 10 wears respectively into pad 13, sleeve 14, spring 15, on rotating disk 20 and the inertia rotating disk 30, and each is provided with several concave arc grooves 21 relatively at the opposing side of rotating disk 20 and inertia rotating disk 30,31, this concave arc groove 21,31 is the shallow grooves in middle dark both sides, it is best shown among Fig. 3, set concave arc groove 21,31 purposes are to be used for ccontaining steel ball 32, and this rotating disk 20 inwardly convexes with a tooth portion 22, inertia rotating disk 30 wears into an electromagnet 33 and a bearing 34 in addition, this electromagnet 33 is provided with two holes 331, be provided with a cover cap 50 in addition, described cover cap 50 is convexly equipped with a cylinder 51 in all members are placed in, thereby and be provided with on the cover cap 50 lockhole 52 can by screw 55 with cover cap 50 locking on drive motor 10, and also be provided with two holes 53 on the cover cap 50, for utilizing two-screw 54 that electromagnet 33 is locked on cover cap 50, its whole structure as shown in Figure 2.

The utility model is being done the time spent, as Fig. 2, shown in 3, when electromagnet 33 no electric circuits, its electromagnet 33 does not just have suction, the rotating shaft 11 that driven of this drive motor 10 just can drive rotating disk 20 like this, and because set therebetween spring 15, make this rotating disk 20 can utilize the steel ball 32 of its concave arc groove 21 pressing closer inertia rotating disk 30, make inertia rotating disk 30 and rotating disk 20 be synchronous rotational speed, and because with the relation of speed, and can make concave arc groove 21 therebetween, steel balls 32 in 31 are because action of centrifugal force, and drop on two concave arc grooves 21,31 centre is than the depths, therefore the distance of its rotating disk 20 and inertia rotating disk 30 is minimum, as shown in Figure 3.

And when electromagnet 33 of the present utility model is switched on, can produce a suction to attract inertia rotating disk 30, and make inertia rotating disk 30 be offset to electromagnet 33 directions slightly, and because the cause of electromagnet 33 suction, so can make that the rotating speed of inertia rotating disk 30 can be slack-off, but the rotating speed of drive motor 10 still is an output speed, this is to cause its concave arc groove 21 because of one fast one slow relation, steel ball 32 in 31 can roll to concave arc groove 21,31 shallow limit, so can cause the distance between rotating disk 20 and the inertia rotating disk 30 to become big (meaning that can push open mutually just), as shown in Figure 5, but because electromagnet 33 is to be hubbed on the cover cap 50, therefore its inertia rotating disk 30 of linking of being pivoted can displacement distance, so can cause the elastic force of rotating disk 20 meeting antagonistic springs 15 to move down owing to the top system relation of steel ball 32, as shown in Figure 4, pushing open of rotating disk 20 and can cause tooth portion 22 that its rotating disk 20 protrudes to be fastened on to be hubbed at the other gear 40 of rotating shaft 11, therefore, the energising of its electromagnet 33 and can cause the driving of the gear 40 of its drive motor 10, what deserves to be mentioned is, this electromagnet 33 does not need to switch on always, it just can have been switched on after making rotating disk 20 and inertia rotating disk 30 push open mutually as long as switch in due course again, because the inertial force between rotating disk 20 and the inertia rotating disk 30 can make its distance apart keep certain, so its electromagnet 33 just needn't have been switched on again, and because the magnetic force of electromagnet 33 is quite big, and owing to motor rotary speed is exceedingly fast, so its electromagnet 33 can be the function that flashy energising just can reach its rotating disk 20 of separation and inertia rotating disk 30.
