Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 3 to Fig. 5 shows the structural representation of the overrunning clutch of present embodiment, as can be seen from the figure, the overrunning clutch of present embodiment comprises active member 10 and drive element 20, wherein, active member 10 rotating settings also can be moved vertically, active member 10 is provided with first tooth 11, and this first tooth 11 has first inclined-plane 112 and along axially extended first facade 111 of active member 10.Drive element 20 arranges rotationally, drive element 20 is provided with second tooth 21, this second tooth 21 has second inclined-plane 212 and along axially extended second facade 211 of drive element 20, second tooth 21 cooperates with first facade 111 by second facade 211, cooperates with first inclined-plane 112 by second inclined-plane 212.When the rotating speed of active member 10 during greater than the rotating speed of drive element 20, first facade 111 and 211 engagements of second facade, active member 10 drives drive elements 20 and rotates.When the rotating speed of drive element 20 during greater than the rotating speed of active member 10, second inclined- plane 212 and 112 engagements of first inclined-plane, cooperation by 212 on first inclined-plane 112 and second inclined-plane, drive element 20 is when driving active member 10 rotations, also drive active member 10 axially moving along active member 10, make active member 10 break away from drive element 20, realize surmounting of drive element 20.Compare the free wheel device of prior art, the free wheel device of present embodiment is finished the driving between active member 10 and the drive element 20 by the cooperation of first tooth and second tooth and is surmounted, need not friction, wedging device are installed between active member 10 and drive element 20, make that the overall structure of free wheel device is simple more, reliable.
In the present embodiment, first tooth 11 and second tooth 21 are a plurality of, and preferably, first tooth 11 and second tooth 21 are axial tooth, can reduce the radial dimension of active member 10 and drive element 20 like this.First tooth 11 is similar to first tooth 11 along the setting that extends axially and protrude from active member 10, the second teeth 21 of active member 10, extends axially and protrude from drive element 20 along drive element 20.When first tooth 11 and second tooth 21 were axial tooth, first facade 111 and first inclined-plane 112 on first tooth 11 were oppositely arranged, and first facade 111 extends along the axis of active member 10.Second facade 211 and second inclined-plane 212 of second tooth 21 are oppositely arranged, and second facade 211 is along the axis extension of drive element 20.Preferably, a plurality of first teeth 11 circumferentially evenly distribute along active member 10, and a plurality of second teeth 21 circumferentially evenly distribute along drive element 20.
The free wheel device of present embodiment in use, Yi Dong active member 10 vertically, first tooth 11 on the active member 10 is meshing with each other with second tooth 21 on the drive element 20, be each first tooth 11 all between two second adjacent teeth 21, each second tooth 21 is all between two first adjacent teeth 11.When active member 10 drives drive element 20 rotations, first facade 111 of first tooth 11 and second facade 211 of second tooth 21 are meshing with each other, first tooth 11 applies first driving force by second facade 211 of 111 pairs of second teeth 21 of first facade, second tooth 21 is together rotated with first tooth 11, rotate thereby make active member 10 drive drive element 20.Because first driving force between first tooth 11 and second tooth 21 is the tangential force of transmitting between two facades, so other motion does not take place except rotating drive element 20.
When the rotating speed of drive element 20 during greater than active member 10, the input shaft 30 that driving active member 10 rotates stops operating, 211 of first facade 111 and second facades break away from engagement, and second inclined-plane 212 and first inclined-plane 112 are meshing with each other, and drive element 20 begins to drive active member 10.Drive element 20 is when rotating, apply second driving force by 212 pairs of first inclined-planes 112, second inclined-plane, because second driving force is to produce between two inclined-planes, so second driving force that 212 pairs of first inclined-planes 112, second inclined-plane apply can be decomposed into tangential force and axial force, active member 10 rotates under the driving of the tangential force that second driving force decomposites, axial motion takes place under the driving of the axial force that second driving force decomposites, under the driving of drive element 20, active member 10 breaks away from drive element 20 away from drive element 20 until active member 10 vertically fully when rotating, at this moment, drive element 20 dallies, and realizes surmounting.
The active member 10 of the free wheel device of present embodiment is driven by input shaft 30 and rotates, active member 10 is provided be used to the mounting hole that holds input shaft 30 away from an end of first tooth 11, input shaft 30 is provided with projection 31, the inwall of mounting hole is provided with the chute that cooperates with projection 31, this chute is the tip chute that has certain angle with the axis of mounting hole, preferably, tip chute is the spiral chute 13 suitable with being arranged on projection 31 on the input shaft 30.When input shaft 30 rotated, active member 10 with under the driving of spiral chute 13 cooperates, from 20 moving along axis to drive element away from the initial position of drive element 20, thereby meshed active member 10 and drive element 20 at projection 31.When the rotating speed of drive element 20 during greater than active member 10, input shaft 30 stops operating, active member 10 is subjected to the axial force distribution of drive element 20, under the cooperation of projection 31 and spiral chute 13, active member 10 carries out axial movement to initial position, and gradually away from drive element 20, break away from fully until active member 10 and drive element 20, get back to initial position.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
