Description
Technical field
The utility model relates to a kind of centrifugal clutch, is specifically related to a kind of secondary reinforcement centrifugal clutch.
Background technique
Centrifugal clutch is equivalent to mechanical " recloser "; Its effect is to make motor approach startup smoothly under the unloaded fully condition; After motor reaches certain rotating speed, utilize centrifugal clutch to connect the power transmission between motor shaft and the transmission shaft automatically, thereby make the running of motor bringing onto load.Therefore, adopt centrifugal clutch, can reduce the motor bringing onto load very effectively and start the inrush current that is caused, and significantly shorten the holdup time of inrush current, the motor feels hot thereby alleviate greatly.
The traditional centrifugal clutch, as depicted in figs. 1 and 2, all be direct acting type basically, promptly centrifugal weight is exactly the power output element, directly contacts with driven member.The centrifugal clutch of this direct acting type, in general physical dimension is bigger, can't be used for the restricted occasion of bulk, also is not suitable for the startup of heavy-duty motor.If can be under the prerequisite that guarantees compact structure, the centrifugal force with centrifugal weight produces through exporting after the boosting mechanism amplification again, can significantly promote the technical order of clutch undoubtedly, and can enlarge its application area.
An existing reinforcement centrifugal clutch; Like Fig. 3, shown in Figure 4; Be the quadrature reinforcement centrifugal clutch that once centrifugal force of centrifugal weight is carried out the first order force amplification that utilizes the angular effect of wedge and toggle mechanism, but both clutch reinforcements are big inadequately, and the wedge surface among Fig. 3 is easy to wearing and tearing; Stuck phenomenon might appear in the toggle among Fig. 4, and centrifugal clutch is short working life.
For solving the problem that above-mentioned four kinds of structures exist, the centrifugal clutch that need to design a kind of compact structure, weight is little, ouput force is big and the life-span is long.
Summary of the invention
The goal of the invention of the utility model provides a kind of secondary reinforcement centrifugal clutch; Improvement through structure; Can the centrifugal force of force amplifying weight be amplified in advance after-appliedly on the output pouring weight, the clutch compact overall structure, weight is little, ouput force is big, long service life.
For reaching the foregoing invention purpose; The technological scheme that the utility model adopts is: a kind of secondary reinforcement centrifugal clutch; Comprise driving link, in uniform way be slidingly connected at least 2 force amplifying weights on the said driving link, be slidingly connected at least 2 output pouring weights on the said driving link in uniform way; Said force amplifying weight is crisscross arranged with the output pouring weight; Be provided with the bearing that is fixedly connected with said driving link between each said force amplifying weight and the adjacent output pouring weight, be hinged with lever on the said bearing, one section lever between said bearing and force amplifying weight is a drive end; One section lever between said bearing and output pouring weight is a driven end; Position corresponding to said lever on the said force amplifying weight offers guiding groove, and said drive end cunning inserts in the guiding groove, and said driven end constitutes driving through linkage structure and said output pouring weight and is connected.
In the technique scheme, said linkage structure comprises the rolling element that is articulated in said driven end end and is articulated in the driven roller on the said output pouring weight sidewall.
Preferably, said rolling element is a rolling bearing.
In the technique scheme, said drive end end is hinged with roller, and said roller constitutes rolling with the inwall of said guiding groove and is connected.
The working principle of the utility model during as clutch is described below:
When said driving link from static when beginning to rotate, said output pouring weight and force amplifying weight be in self action of centrifugal force lower edge centrifugal direction motion separately, gradually near the inwall of driven member.
Simultaneously, force amplifying weight is in movement process, and the part component that utilizes guiding groove and driving between the lever drive end to be connected force amplifying weight centrifugal force puts on the lever, impels lever to rotate around bearing.
Then, lever utilizes its driven end to be connected with the driving of output between the pouring weight, put on the output pouring weight one and point to the thrust of output pouring weight centrifugal direction, thereby quicken to export pouring weight to the driven member inwall near.
When the angular velocity of driving link is lower, when the distortion that Returnning spring produces did not also reach design load, the exterior arc surface of output pouring weight did not reach the inwall of driven member, and driven member will keep state of rest in this section period; When the angular velocity of driving link reached critical value, the exterior arc surface of output pouring weight contacted with the inwall of driven member, and this moment, the amount of deformation of Returnning spring also reached design load, bore maximum working load, and the angular velocity of driving link is called engagement angle speed at this moment; Driving link continues to quicken rotation; After the angular velocity of driving link surpasses engagement angle speed; Exterior arc surface and the inwall of driven member of output pouring weight will keep in touch always, and driven member makes driven member begin to follow driving link to rotate with same angular velocity with exporting frictional force between the pouring weight exterior arc surface.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1. the utility model adopts the lever transmission force amplifying weight to put on the thrust on the output pouring weight; The driving force that makes the force amplifying weight that the drive end of lever receives is when the driven end of lever transmission to lever, and driving force is amplified by one-level, and the lever actuated rolling bearing promotes driven roller; Through angular effect; Driving force is amplified by secondary, constitutes secondary reinforcement centrifugal clutch, is convenient to apply to low speed and high-power field.
2. the thrust of the ouput force of the utility model after by the centrifugal force component amplification of centrifugal force and the force amplifying weight of output pouring weight constitutes, and ouput force is big, and compact structure, the weight of clutch are little.
3. adopt the roller transmission of drive force between lever driven end of the utility model and the output pouring weight, reliable transmission, not easy to wear, can be not stuck, long service life.
4. the utility model is under the suitable condition of physical dimension, can use less but the friction material that wear resistance is good of friction factor, like iron-base powder metallurgy material etc., thus significant prolongation working life, low cost of manufacture.
