Abstract

A clutch comprises a pair of relatively rotatable members 101, 104 coupled together by members 107 mounted on pivoted levers 106 and engaging respective recesses 108 in the shaft 101, the outer end of each lever 106 being provided with a weight 102 which is spring-loaded whereby, because of centrifugal force, each member engages its recess with greater force as the clutch speed increases. In a modification (Fig 2), the clutch includes a radially movable weight which causes the engagement force in the respective recess to decrease as the speed increases. <IMAGE>

Description

TITLE Centrifugal Type Coupling Torsion Modulating Means And Device.
SUMMARY OF THE INVENTION The present invention relates to a centrifugal type coupling torsion modulating means and device, and particularly to a gyrating device having a mechanism which can increase or decrease centrifugal force against or disengage with the limit coupling torsion device subject to the change of rotational speed; or a torsion coupling device being operative subject to the rotational speed and concerning opposite characteristics to above mentioned.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing the structure and principle of the present embodiment having greater coupling torsion at high speed and having less coupling torsion or disengaged at low speed.
FIG. 2 is a diagram showing the structure and principle of the present embodiment having less coupling torsion or disengaged at high speed and having greater coupling torsion at low speed.
DETAILED DESCRIPTION OF THE INVENTION The conventional torsion coupling device is a fixed torsion coupling device which bears no relation to rotational speed. The present invention relates to a torsion coupling means appearing a direct or inverse proportion to rotational speed, and related structure may include such types depending on requirement: (A) greater coupling torsion at high speed and less coupling torsion or disengaged at low speed (B) less coupling torsion or disengaged at high speed and greater coupling torsion at low speed.
The basic principle for the present design is described below: Referring to FIG. 1, it is a diagram showing the structure and principle of the present embodiment having greater coupling torsion at high speed and having less coupling torsion or disengaged at low speed, wherein: a shaft 101 can be a gyrator resembling a shaft, disc or other shape, or a fixed body for proceeding relative gyration between with a relative motion body, and a friction device 108 such as friction face, sink groove, slot, blind hole or the like is mounted against the coupling face for producing coupling torsion;; a relative motion body 104 for proceeding relative motion between with above-said shaft 101 - one keeping still and the other moves or both move together, it may mount up at least one crank 106 and torsion modulating structure having centrifugal block 102, and the crank is coupling with the relative motion body 104 by means of a pivot shaft or other mandrel type coupling structure, for swinging adjustment along with centrifugal force; the centrifugal block is located on the end appearing the reversed direction to the action of the crank so as to apply more pressure upon the coupling structure when centrifugal force is greater, and the sliding face against the shaft 101 has a torsion coupling unit 107 of sliding friction face or other rolling or sliding friction structure for producing coupling force jointly with friction structure 108 on the shaft 101; aforesaid crank structure may further include a steady spring 103 for providing basic packing prestress against the torsion coupling unit 107 in order to define minimal torsion, or reversing structure mounts a basic spring so as to define the maximal torsion.
From the aforesaid structure we can find: when relative motion body is driven, the relationship with the center of shaft as such: centrifugal action of centrifugal block on the crank is so increased at high speed as to enhance relatively coupling pressure against the limit coupling structure for increasing rated coupling torsion; centrifugal action of centrifugal block on the crank is so decreased at low speed as to reduce relatively coupling pressure against the limit coupling structure for decreasing rated coupling torsion or disengaging;; Aforesaid limit torsion coupling packing face includes the conventional forcibly reversed type gearing structure or slidable or rolling type friction structure, i.e. aforesaid coupling force is changed along with coupling pressure, and coupling force is increased/decreased as a result of forced pressure from respective corresponding component vectors or disengaging due to the change of pressure.
Another type of the present design is the operating structure for decreasing coupling force at high speed and increasing coupling force at low speed.
Referring to FIG. 2, it is diagram showing the structure and principle of decreasing coupling torsion or disengaging at high speed and increasing coupling torsion at low speed, wherein: a shaft 201 can be a gyrator resembling a shaft, disc or other shape, or a fixed body for proceeding relative gyration between with a relative motion body, and a friction device 208 such as friction face, sink groove, slot, blind hole or the like is mounted against the coupling face for producing coupling torsion;; a relative motion body 204 being static or dynamic for proceeding relative motion between with above-said shaft 201 - one keeping still and the other moves or both move together, and it may mount up at least one torsion modulating structure having centrifugal block 202 by means of a ring projection, and the centrifugal block is so located as to control the torsion coupling structure directly or indirectly for reducing pressure against the coupling structure from the basic spring 203 or disengaging at greater centrifugal force, and the sliding face against the shaft 201 has a torsion coupling unit 207 of sliding friction face or other rolling or sliding friction structure for producing coupling force jointly with friction structure 208 on the shaft 201; aforesaid crank structure may further include a basic spring 203 for providing basic packing prestress against the torsion coupling unit 207 in order to define minimal torsion, or reversing structure mounts a basic spring so as to define the rotational speed for disengaging.
From the aforesaid structure we can find: when relative motion body is driven, the relationship with the center of shaft as such: centrifugal action of centrifugal block on the crank is so increased at high speed as to reduce relatively coupling pressure against the limit coupling structure for decreasing rated coupling torsion; centrifugal action of centrifugal block on the crank is decreased at low speed and relatively coupling pressure that basic spring applies to the limit coupling structure is greater than at high speed so as to increase rated coupling torsion.
Aforesaid limit torsion coupling packing face includes the conventional forcibly reversed type gearing structure or slidable or rolling type friction structure, i.e. aforesaid coupling force is changed along with coupling pressure, and coupling force is increased/decreased as a result of forced pressure from respective corresponding component vectors or disengaging due to the change of pressure.
To conclude above statement, the present design can control the torsion of limit coupling structure along with the change in rotational speed by means of centrifugal force and thereby accomplish the performance in combination of conventional centrifugal type clutch and fixed type limit torsion device so as to provide a basic driving element with new function for manufacturing industrial purpose.
