Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, the swelling coupling clutch 100 includes clutch 10, the connection disk set on 10 one end of clutch 20 and it is coupled the fixed half a coupler 30 of disk 20 with this.

The clutch 10 is non-contact wedge block clutch comprising inner ring 11 is sheathed on the outside of inner ring 11 and is spaced and sets The outer ring 12 set, the bearing 13 between inner ring 11 and outer ring 12 and wedge assemblies 14.Shape between the inner ring 11 and outer ring 12 At raceway, the wedge assemblies 14 are set in raceway.

In the present embodiment, bearing 13 is two, and each 13 two sides of bearing are respectively equipped with baffle ring 15 and end cap 16, by bearing 13 Sealing.The wedge assemblies 14 are set between two bearings 13, and two sides are respectively equipped with fixed baffle ring, by baffle ring 15 by wedge assemblies 14 is fixed with inner ring 11.Please refer to Fig. 2, which includes two yoke plates 140 of opposed juxtaposition setting, is set to two yokes Between plate 140 and close to the voussoir 141 of its side end and it is connected between two yoke plates 140 and the backing pin for fixing two yoke plates 140 142 with latch 143.Two yoke plate 140 is fixed between inner ring 11 and outer ring 12.The corresponding yoke plate 140 of each voussoir 141 prolongs respectively A cylindrical shaft is stretched out, voussoir is made to can be rotated setting.It is arranged with a reduction torsion spring 145 respectively outside each cylindrical shaft, reduction torsion spring 145 One end is inserted into voussoir 141, and the other end is resisted against on backing pin 142.The corresponding inner ring 11 of each voussoir 141 and outer ring 12 be respectively equipped with Its wear-resisting arcwall face contacted.

The clutch 10 drives inner ring 11 to rotate together with wedge assemblies 14 in use, host-initiated, when rotation generate from Mental and physical efforts form a torque to the supporting point of voussoir 141, direction and reduction torsion spring 145 be applied to voussoir 141 on the contrary, making The trend that voussoir 141 and outer ring 12 disengage, but when voussoir 141 is multiple since the centrifugal moment that rotation generates also is not enough to overcome When being applied to the torque of voussoir 141, at this moment voussoir 141 contacts with each other position torsional spring 145 with 11 working face of inner ring, and with outer generation phase To sliding friction.When the axis revolving speed of connection inner ring 11 is gradually increased, its revolving speed of inner ring 11 is equal to or more than the minimum of clutch 10 When non-contact revolving speed, at this moment generated centrifugal moment is equal to or more than the torque of 145 pre-add of reduction torsion spring and the matter of voussoir 141 Torque forces voussoir 141 to deviate in 140 supported hole of yoke plate in this way and disengages and leaned against on backing pin 142 with outer ring 12, this The non-contact operating of Shi Shixian, no friction, reduce fever at abrasion, improve service life.

It is fixed with a check connecting lever 18 outside the outer ring 12, one end of the check connecting lever 18 is fixed on outer ring 12, the other end It is fixed in the rack of transmission mechanism.

One end of the inner ring 11 is arranged by extending out to outside, the connection disk 20 in outer ring 12 and is fixed on inner ring 11 in outer ring The end in 12 outsides.It is fixedly connected between the connection disk 20 and inner ring 11 by spline.

The half a coupler 30 includes a barrel 31 and the ring flange 32 extended outward to form by one end of barrel 31.It should An expansion set 33 is fixed in barrel 31, the inner hole of the expansion set 33 is corresponding with the inner hole of inner ring 11.In the half a coupler 30 Expansion set 33 makes its seamless connectivity, can bear heavy duty, there is good interchangeability, eliminate transmission for connecting with main shaft Disadvantage.The ring flange 32 be coupled disk 20 and connected by multiple fixation kits.Each fixation kit includes being arranged in be coupled disk 20 With pin 51, the resilient sleeve 52 that is sheathed on outside pin 51 and the locking nut 53 for being fixed on 51 one end of pin in ring flange 32. One end of the pin 51 has a head 55, and the other end has screw thread.55 end of head of the pin 51, which is arranged in, to be coupled in disk 20, The end of thread extends to the outside of ring flange 32.The resilient sleeve 52 is sheathed on one end close to the head of pin 51, both ends difference It is resisted against on head 55 and the ring flange 32 of pin 51.The threads of the locking nut 53 and pin 51 are simultaneously located at ring flange 32 Outside.The ring flange 32 and the connection type for being coupled disk 20, structure is simple, can compensate opposite offset, and increase damping energy Power.

The swelling coupling clutch 100, which is realized, is coupled driving and driven two-axis synchronization rotation and transmitting power, while also preventing non-return Turn.The swelling coupling clutch is compact-sized, multi-purpose, a saving installation control, efficiently solves such as conveyer equipment hardly possible The problem of to install holdback additional.

Fig. 3 is the application of the swelling coupling clutch 100 in tilting band conveyer, is connected at motor 60 and slows down Between machine 70, the axis of motor 60 is fixed in expansion set 33, and the axis of speed reducer 70 is arranged in inner ring 11, and speed reducer 70 passes through shaft coupling Device 90 is connect with conveyer belt 80.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
