Abstract

The utility model discloses a centrifugal reduction device, comprising a friction disk, a frisbee and a friction block, wherein the friction disk is in a dick shape, and a friction ring is arranged on the circumference; the frisbee having a rotating shaft is disposed in the friction disk; the friction block which can radially slide is arranged on the frisbee; the friction block can be closely leaned on the friction ring. When the frisbee is turned through the rotating shaft under the driving of the outside force, the friction block on the frisbee is thrown off and slid to the side of the frisbee because of the action of centrifugal force. The edge of the friction block is closely leaned on the friction ring of the friction disk, thereby producing sliding friction force to limit the rotary speed of the frisbee and reduce the speed. The higher the rotary speed of the frisbee is, the larger the joint force between the friction block and the friction ring is, thereby the friction force is larger and the speed-limiting force is greater.

Description

Centrifugal speed reducer

Technical field

The utility model relates to a kind of retarder, refers in particular to a kind of centrifugal speed reducer.

Background technique

Present retarder relies on the gear engagement differential reducing mostly, and structure is comparatively complicated, and volume is bigger, and it is higher to add two worker's fabricating cost, brings certain difficulty and inconvenience to use.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of volume little, simple in structure, effective centrifugal speed reducer slows down.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of centrifugal speed reducer, comprise friction disk, flying disc, brake pad, friction disk is a disc, week is along dead turn is arranged, be provided with the flying disc of band rotating shaft in the friction disk, flying disc is provided with the brake pad that can radially slide, and brake pad can recline with the dead turn of friction disk.

Further, the radian on its friction limit of brake pad is consistent with the radian of the dead turn of friction disk, so that brake pad when reclining dead turn, has maximum friction area.

When flying disc rotates under external force drives by its rotating shaft, brake pad on the flying disc gets rid of cunning because of action of centrifugal force to the flying disc avris, the recline dead turn of friction disk of the edge of brake pad, produce the rotating speed of force of sliding friction restriction flying disc, play the effect of deceleration, the flying disc rotating speed is high more, and the applying power of brake pad and dead turn is big more, frictional force is just big more, and speed limit power is big more.

The beneficial effects of the utility model are: volume is little, and is simple in structure, easily manufactured, and cost is low, and the deceleration effect is good.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the cutaway view Amplified image of A-A ' among Fig. 1.

1. friction disk 1-1. dead turns, 2. flying discs, 3. brake pads, 4. chutes, 5. cushion blocks, 6. fixture blocks among the figure.

Embodiment

A kind of centrifugal speed reducer as shown in Figure 1, comprise friction disk 1, flying disc 2, brake pad 3, friction disk 1 is a disc, week is along dead turn 1-1 is arranged, be provided with the flying disc 2 of band rotating shaft in the friction disk 1, flying disc 2 is provided with the brake pad 3 that can radially slide, and brake pad 3 can recline with the dead turn 1-1 of friction disk 1.The radian on brake pad 3 its friction limits is consistent with the radian of dead turn 1-1, so that brake pad 3 has maximum friction area when reclining dead turn 1-1.

As shown in Figure 2, the radial direction corresponding position has the chute 4 of hollow out on the flying disc 2, brake pad 3 is at the upside of chute 4, fixture block 6 is at the downside of chute 5, the width of fixture block 6 is more bigger than the width of chute 5, can block flying disc 2 like this, cushion block 5 places 4 of chutes, the thickness of the thickness of cushion block 5 and flying disc 2 quite or slightly thicker than flying disc 2, width is consistent with groove width or more smaller than groove width, and length is shorter than groove, and cushion block 5 can be done linear slide in chute 4 like this, with brake pad 3, cushion block 5, fixture block 6 threes are fixedly connected by rivet, and brake pad 3 can be done on flying disc 2 and radially slide and don't break away from flying disc 2 like this.

When flying disc 2 rotates under external force drives by its rotating shaft, brake pad 3 on the flying disc 2 gets rid of cunning because of action of centrifugal force to the avris of flying disc 2, the recline dead turn 1-1 of friction disk 1 of the edge of brake pad 3, produce the rotating speed of force of sliding friction restriction flying disc 2, play the effect of deceleration, flying disc 2 rotating speeds are high more, and brake pad 3 is big more with the applying power of dead turn 1-1, frictional force is just big more, and speed limit power is big more.

This centrifugal speed reducer can be applicable to slow falling on the equipment such as machine, buffer, and volume is little, and is simple in structure, and the deceleration effect is good.
