Abstract
The utility model discloses a torque limit centrifugal clutch, comprising a machine core, a friction block, a friction block arm, a machine core groove and a tension spring. The utility model is characterized in that the friction block arm is rectangular, and the rectangular machine core groove which corresponds to the rectangular friction block arm is arranged on the machine core. The structure ensures that when the friction block becomes thinner due to abrasion and when the friction block is protruded outwards, a gap between the friction block and the machine core groove can not become too large, and the mutual collision among the friction blocks can be avoided. Accordingly, noise can be reduced, the service life of the clutch can be extended, and the clutch can be guaranteed to run stably and reliably.
Description
The utility model relates to the coupling arrangement between a kind of prime mover and the working machine, is suitable for using when transferring power is with the protection of limit square between them.
A kind of centrifugal friction limit square clutch arranged in the past, and it is to utilize action of centrifugal force, and the brake pad on prime mover is contacted with working machine, and frictionally drives working machine and rotates.Though this kind clutch is simple in structure, can reach the effect that drives working machine, but it centrifugal with the movement groove all be fan-shaped, after the brake pad attenuation, it is big that gap between movement groove and the brake pad arm becomes, collision mutually between the brake pad produces noise when causing prime mover starting, reduces using effect and life-span.
Task of the present utility model is to provide a kind of novel limit square centrifugal clutch, it can be when the outside generation of brake pad attenuation brake pad arm moves radially, the gap of brake pad arm and movement groove was unlikely to ambassador's brake pad and produced collision, thereby minimizing noise, guarantee using effect, prolong the working life of clutch.
Task of the present utility model is achieved in that limit square centrifugal clutch includes movement, brake pad, brake pad arm, movement groove, extension spring, and it is characterized in that: the brake pad arm is a rectangle, has on the movement and the corresponding rectangle movement of rectangle brake pad arm groove.
The utility model is because brake pad arm and movement groove are rectangle, so when brake pad is subjected to abrasion attenuation brake pad radially outwardly projecting, gap between brake pad arm and the movement groove is unlikely to excessive, avoided the mutual collision of each brake pad, thereby reduced noise, prolonged the working life of clutch, guaranteed that clutch reliablely and stablely turns round.
Fig. 1 is a structural representation of the present utility model.
Further describe an embodiment of the present utility model below in conjunction with accompanying drawing.
Each brake pad 2 relies on extension spring 1 to interconnect, the lower end of brake pad 2 is rectangular brake pad arm 3, movement groove 5 also is a rectangle, corresponding with brake pad arm 3, be that brake pad arm 3 can insert in the movement groove 5, rectangular arm hole 4 is arranged on brake pad arm 3, and arm hole 4 relies on drift bolt to stretch within the specific limits.When the motor rotation made prime mover startup reach certain rotating speed, friction arms piece 3 produced radial centrifugal force under action of centrifugal force, the drive wheel of brake pad 2 and working machine is contacted, and when frictional force acquired a certain degree, working machine started.Brake pad 2 is owing to frequently rubbed, attenuation easily, and the distance that this moment, outwards got rid of in friction arms piece 3 footpaths will increase, because friction arms piece 3 and movement groove 5 are rectangle, so brake pad 2 is difficult for rocking and produces collision.
