The present invention relates to a kind of scissor gears, its can eliminate it and the gear of the side that is meshed with it between backlash.
Background technique
In the past, for example use scissor gears in manual transmission at automobile, promptly, but pinion is installed being installed on free rotation mode on 1 grade of driven gear on the countershaft and 2 grades of driven gears, with eliminate its with as the backlash between 1 grade of actuation gear of the gear of the side that is meshed with it and the 2 grades of actuation gears.
This scissor gears also can be used as drive with or non-driving gear, be used for the device of generation coggings such as the fuel-injection pump of engine for automobile or camshaft.
Particularly, scissor gears comprises: master gear, and it has the regulation number of teeth; Pinion, it has the number of teeth identical with above-mentioned master gear, and master gear axially on adjacency with it, and with master gear with the gear engagement of the side that is meshed with it; Spring, it is along making pinion apply power (for example, opening with reference to the open communique of Japanese Utility Model is real that flat 5-57499 number, the open communique of Japanese Utility Model are real opens flat 6-20947 number, the open communique spy of Japan Patent and open flat 7-19319 number, the open communique spy of Japan Patent and open flat 11-303974 number, the open communique spy of Japan Patent and open 2000-257698 number, the open communique spy of Japan Patent and open 2001-12581 number, the open communique spy of Japan Patent and open 2001-12582 number) with respect to the direction of master gear rotation to pinion.
And, when making scissor gears and during the gear engagement of the side that is meshed with it, the tooth of the gear of the side that is meshed with it is folded by the tooth of master gear and pinion by the elastic force of spring, thus eliminated scissor gears and the gear of the side that is meshed with it between backlash.
Figure 18 has represented the exploded perspective view of original scissor gears.Master gear 2 has a plurality of holes 5 of flange 4 and riveted joint usefulness.Pinion 6 has a plurality of holes 7 of riveted joint usefulness.So, when the assembling scissor gears, at first, between master gear 2 and pinion 6, sandwich spring 8, under this state, make pinion 6 chimeric with the flange 4 of master gear 2.With rivet 10 pinion 6 and master gear 2 are fastenedly connected then.
In this scissor gears, pinion 6 is diametrically opposed in master gear 2 location by flange 4.In addition, pinion 6 axially and on the sense of rotation is being located with respect to master gear 2 by rivet 10.

In addition, in order to keep the high load high speed rotating, actuation gear and driven gear generally adopt helical gear.(in addition) on the other hand, pinion reduces cost and makes things convenient for reasons such as making to adopt horizontal gear because of considering, forms by punching press stamping-out steel plate.Therefore, the area that the tooth of this pinion and the actuation gear that is formed by helical gear is contacted is little, is that line contacts between mutually.
Here, on the flank of tooth of the pinion that the punching press stamping-out forms, on the stamping-out direction, begin most with the contacted part of punch die be shearing plane, therefore be smooth face.Yet the other parts continuous with this shearing plane are fracture surface then, thereby become coarse face, the precision deterioration of the tooth contacted (engagement) of itself and actuation gear.
Therefore, the flank of tooth of the fracture surface of pinion part and actuation gear contacts when meshing with line, gear engagement degree deterioration then, thereby can't remove backlash well.
Therefore, existing pinion will be processed the flank of tooth behind the punching press stamping-out, is processed into to be smooth face, improves pinion and contacts with the between cog of actuation gear, thereby improve the accuracy of mesh, eliminates backlash effectively.
Yet, if behind the punching press stamping-out, further the flank of tooth is smoothly processed, need spend two procedures, cause the cost of pinion to increase.
For addressing this problem, register the open motion that relevant scissor gears is arranged for communique 5-30599 number of No. 2595071 communique and Japanese Utility Model in the Japan Patent model utility.The feature that model utility is registered the scissor gears of being put down in writing in No. 2595071 communique is as follows, that is, only have the part and the skew back gear that is meshed with it of the shearing plane of punching press stamping-out to contact on the pinion.Yet this scissor gears but has following problem: because of the helical gear of the pinion and the side that is meshed with it is that line contacts, so durability is low, cause its hypofunction originally.
In addition, in the scissor gears of in the open communique 5-30599 communique of model utility, being put down in writing,, the flank of tooth of pinion is formed the shape that can carry out the face contact along the helical gear flank of tooth of the side that is meshed with it by punch process.In this case, when forming the flank of tooth of pinion, must increase the punching press limit of collapsing, to form the shape that to carry out the face contact along the helical gear flank of tooth of the side that is meshed with it.Yet, originally just being difficult to set the punching press limit of collapsing, the making of metal mold is also wanted repetition test.In addition, because during the abrasion of metal mold initial stage and metal mold, the limit amount of collapsing can change, so necessary periodic maintenance metal mold.In addition, protrude in the collapse overlap of the opposite side in limit of punching press and also must carry out machining for removing, this machining just becomes the essential factor that cost increases.
