Description
Technical field
The utility model relates to a kind of free wheel device, especially relates to a kind of to tiltedly colluding the isostructural improvement of tooth free wheel device.
Background technique
Free wheel device is the engagement transmitting torque that utilizes composition elements such as click, castellated tooth, is mainly used in rate conversion, prevents to reverse, the occasion of intermittent movement, and the advantage of this clutch is simple in structure, and is easy to manufacture.Chinese patent discloses a kind of ratchet bidirectional free wheel device (notice of authorization number: CN 2077930U), it is by working portion, operative section is formed, working portion comprises: pawl base, the both sides of pawl base respectively with flange, positioning plate fixes, the positioning plate end face is fixed with the fixed cone joint, flexible awl joint in the flange end face, the joint spring is pressed in movable awl joint afterbody, ratchet, its both sides respectively with the fixed cone joint, elasticity awl joint contacts, the ratchet section is the arc wedge shape, the ratchet afterbody is half-cylindrical, is connected by bearing between two-way ratchet and flange; Operative section comprises: be contained in the camshaft in the flange plate axial bore, the side of being, the two ends tenon of axle, two ends respectively with heart-shaped cam, anchor shape cam on square hole tightly rivet, the trundle that is enclosed within the heart-shaped cam end is enclosed within the control loops on the flange, be embedded with drag chain between control loops one and flange, an end of shift fork inserts to be handled in the annular groove, and the other end is enclosed within on the declutch shift shaft, steel ball positioning means, steel ball positioning means are set screw, retaining spring, locking ball.But this free wheel device uses in the big torsion of high strength, and owing to it need engage continually, disengagement work, so working life is shorter.
The model utility content
The utility model technical issues that need to address provide a kind of tooth free wheel device that tiltedly colludes, it mainly is to solve the existing in prior technology free wheel device to use in the big torsion of high strength, because it need engage continually, disengagement work, thus working life short etc. technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The tooth free wheel device that tiltedly colludes of the present utility model, comprise shaftgear, it is characterized in that described shaftgear is engaged with the inner circular tooth circle, the Surface of action of inner circular tooth circle and shaftgear is the inclined-plane, be connected with on it and tiltedly collude tooth, the inner circular tooth snare is connected in the outer ring gear, is connected with spring between inner circular tooth circle and the outer ring gear.Shaftgear integral body is "T"-shaped, one end dress bearing, the other end cogged.Shaftgear is processed as a plurality of teeth that tiltedly collude in the one side that is meshed with the inner circular tooth circle, and the leaf that the inner circular tooth circle is meshed with shaftgear processes and tiltedly colludes tooth accordingly, is some inclined-planes on the section that the inner circular tooth circle launches, and tiltedly colludes tooth and is connected on the inclined-plane.Like this, when the rotating speed of shaftgear was lower than outer ring gear, the inner circular tooth circle that flexibly connects with outer ring gear can collude mutually and closes by tiltedly colluding tooth under the effect of spring with shaftgear, forces outer ring gear and shaftgear to rotate together; When the rotating speed of shaftgear was higher than outer ring gear, slide relative between inner circular tooth circle and the shaftgear had promptly produced and has surmounted work.
As preferably, have positioning hole on the described inner circular tooth circle, be provided with the hydraulic pressure ejector pin between positioning hole one end and the outer ring gear, positioning hole is by the main oil gallery of oil duct connection shaft gear inside.The pressure oil that main oil gallery feeds makes it to withstand on the outer ring gear through the oil channel feeding certain pressure of pin that bears down on one.When spring stress fractureed, the hydraulic pressure ejector pin can substitute the effect of spring.
As preferably, described main oil gallery is communicated with grease channel, and the grease channel the other end is located on the Surface of action of inner circular tooth circle and shaftgear.Grease channel can be a plurality of, its internally the Surface of action of annular gear and shaftgear play lubricated buffer function.
As preferably, described inner circular tooth circle is or/and the Surface of action place of shaftgear is provided with the protecting against shock layer.The material of protecting against shock layer can be general alloy material, and it can alleviate impact force, and reduces the noise when meshing.
As preferably, be provided with bearing between the axis body of described outer ring gear and shaftgear, it is more smooth and easy to make that outer ring gear rotates.
Therefore, the utlity model has free wheel device and use in the big torsion of high strength, can comparatively easily engage, throw off the work long service life continually, characteristics such as simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is expansion schematic representation of inner circular tooth circle.
Component, position and numbering among the figure: shaftgear 1, inner circular tooth circle 2, tiltedly collude tooth 3, outer ring gear 4, spring 5, positioning hole 6, hydraulic pressure ejector pin 7, oil duct 8, main oil gallery 9, grease channel 10, protecting against shock layer 11, bearing 12.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: this example tiltedly collude the tooth free wheel device, as Fig. 1, it is "T"-shaped shaftgear 1 that a section is arranged, one end dress bearing, the other end installing gear.The axle inside of shaftgear has main oil gallery 8, and gear parts is engaged with inner circular tooth circle 2, as Fig. 2, inner circular tooth circle 2 is the inclined-plane with the Surface of action of shaftgear 1, oil leab is arranged on it, and is connected with on it and tiltedly colludes tooth 3, the Surface of action of shaftgear with tiltedly collude tooth 3 shapes and be complementary.The Surface of action place of inner circular tooth circle 2 and shaftgear 1 is provided with protecting against shock layer 11.Inner circular tooth circle 2 is actively socketed in the outer ring gear 4, is connected with spring 5 between inner circular tooth circle 2 and the outer ring gear 4, is provided with bearing 12 between the axis body of outer ring gear 4 and shaftgear 1.Have positioning hole 6 on the inner circular tooth circle 2, be provided with hydraulic pressure ejector pin 7 between positioning hole one end and the outer ring gear 4, positioning hole is by the main oil gallery 9 of oil duct 8 connection shaft gears 1 inside.
During use, shaftgear 1 rotates with outer ring gear 4, when the rotating speed of shaftgear 1 was lower than outer ring gear 4, the inner circular tooth circle 2 that flexibly connects with outer ring gear can collude mutually and closes by tiltedly colluding tooth 3 under the effect of spring 5 with shaftgear, forces outer ring gear and shaftgear to rotate together; When the rotating speed of shaftgear was higher than outer ring gear, the inner circular tooth circle meshed in shaftgear, produced the slide relative contact, had promptly produced to surmount work.
