Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in further detail.
As shown in Figure 1, the described contactless voussoir free wheel device of the utility model embodiment, ring 1 in comprising, end cap 2, back-up ring 3, outer shroud 4, bearing 5, fixedly baffle ring 6, baffle ring 8 and voussoir retainer 7, ring 1 is nested with in outer shroud 4 in described, be provided with voussoir retainer 7 in the raceway between interior ring 1 and the outer shroud 4, described voussoir retainer 7 both sides are respectively equipped with end cap 2, end cap 2 is arranged between interior ring 1 and the outer shroud 4, the two end cap 2 outer back-up rings 3 of fixing in outer shroud 4 that are respectively equipped with, end cap 2 can be fixed in outer shroud 4 by back-up ring 3, be provided with bearing 5 between described end cap 2 and the interior ring 1, ring 1 and outer shroud 4 in bearing 5 can support, bear axial force and radial force, coaxality is installed and used in assurance, and not other strength reduces the part heating, be provided with the baffle ring 8 of ring 1 excircle in being fixed between the bearing 5 in left side and the voussoir retainer 7, be provided with the fixedly baffle ring 6 of ring 1 excircle in being fixed between the bearing 5 on right side and the voussoir retainer 7.
Described fixedly baffle ring 6 is identical with baffle ring 8 boundary dimension, and id tolerance is one positive one negative, by fixing baffle ring 6 voussoir retainer 7 and interior ring 1 is connected together.
Shown in Fig. 2-4, described voussoir retainer 7 mainly comprises yoke plate 71, left-handed torsion spring 72, voussoir 73, dextrorotation torsion spring 74, nut 75, backing pin 76, stop pin 77, stop ring 78, encircle outside 1 in described two yoke plates 71 arranged side by side are enclosed within, a plurality of voussoirs 73 are coupling between two yoke plates 71, the cylinder axis at voussoir 73 two ends is set on respectively in the axis hole of two yoke plates 71, voussoir 73 can freely rotate in two yoke plates, 71 axis holes, be provided with the left-handed torsion spring 72 on the cylinder axis that is enclosed within voussoir 73 left ends between the yoke plate 71 in described voussoir 73 and left side, be provided with the dextrorotation torsion spring 74 on the cylinder axis that is enclosed within voussoir 73 right-hand members between the yoke plate 71 on described voussoir 73 and right side.
Described two yoke plates 71 connect by backing pin 76, stop pin 77, and two yoke plates, 71 back interlocking nuts 75 are passed at backing pin 76 two ends, and two yoke plates, 71 back clamping stop rings 78 are passed at stop pin 77 two ends.
Described left-handed torsion spring 72, dextrorotation torsion spring 74 1 ends are separately fixed in the end face aperture of voussoir 73, and left-handed torsion spring 72, dextrorotation torsion spring 74 the other ends are stuck on the backing pin 76.
Described voussoir 73 both sides are the wear-resisting curved working face of the inequality and decentraction of radius, two wear-resisting curved working faces contact with the external diameter of interior ring 1, the internal diameter of outer shroud 4 respectively, and the circular arc flank radius that voussoir 73 contacts with interior ring 1 external diameter is greater than the circular arc flank radius with the contact of outer shroud 4 internal diameters.
Shown in Fig. 5,6, working principle of the present utility model is: when being unrealized the non-contact operation, when outer shroud 4 actives, and when outer shroud 4 just walking around speed equal in ring 1 clutch wedging when just walking around speed, when outer shroud 4 just walking around speed when just walking around speed less than interior ring 1 clutch surmount, when interior ring 1 initiatively the time, interior ring 1 counter-rotating rotating speed is during less than outer shroud 4 counter-rotating rotating speeds, clutch surmounts, clutch wedging when interior ring 1 counter-rotating rotating speed equals outer shroud 4 counter-rotating rotating speeds.
When host-initiated, in driving, encircle 1 and voussoir 73 rotate together, must produce centrifugal force, centrifugal force just has a torque to voussoir 73 strong points, its direction is opposite with the torque that left-handed torsion spring 72, dextrorotation torsion spring 74 impose on voussoir 73.This torque has the trend that voussoir 73 and outer shroud 4 are disengaged.Voussoir 73 centrifugal force increase sharply along with the raising of shaft extension rotating speed, when main frame just starts, the centrifugal force that voussoir 73 produces is not enough to overcome left-handed torsion spring 72, dextrorotation torsion spring 74 imposes on the torque of voussoir 73, voussoir 73 and interior ring 1, outer shroud 4 working surfaces contact with each other, voussoir 73 centrifugal force increase along with the raising of interior ring 1 rotating speed, when rotating speed meets or exceeds the minimum non-contact rotating speed of this clutch, centrifugal torque and increase to left-handed torsion spring 72, dextrorotation torsion spring 74 imposes on the torque of voussoir 73, so just force voussoir 73 deflection and disengage and lean against on the backing pin 76 in yoke plate 71 supported holes with outer shroud 4, thereby make free wheel device realize the non-contact running, there is not friction, do not have wearing and tearing, do not have heating, increase the service life.
As Fig. 7 is the application example of contactless voussoir free wheel device in transmission system, in the middle of this transmission system, main motor 101 is installed, and (W=132kW, n=980r/min) (W=11kW, rotation speed n behind speed reducer 104=69r/min) two cover drive units drive with auxiliary motor 105.A driven device 102 (high-temperature blower), root a tree name need be opened main motor 101, auxiliary motor 105, and the automatic switchover that main motor 101 (at a high speed) or auxiliary motor 105 (low speed) drive driven device 102 is realized by free wheel device 100.
When transmission system begins to start, the general auxiliary motor 105 of opening earlier, after speed reducer 104 slowed down (n=69r/min), the outer shroud 4 by free wheel device 100 drove the axle rotation that ring 1 connects in it, drove driven device 102 turn round slowly (clutch transmits torque at this moment).And then start main motor 101 and drive driven device 102 running, at this moment the interior ring 1 coupling shaft rotating speed of clutch 100 is 980r/min, greater than the rotating speed (n=69r/min) of outer shroud 4, clutch 100 is in and surmounts.Driven device 102 is in normal working.Maintaining or do not worked if desired, can close main motor 101, at this moment again by free wheel device 100 by the switching that surmounts transmitting torque, drive driven device 102 by auxiliary motor 105, free wheel device 100 is housed in this transmission system like this to automatically switch, reduce the resistance when opening, main purpose is saved the energy.
This embodiment is a preferred embodiment of the present utility model, can not limit the utility model, and concrete every rights protection scope is defined by the claims.
