Abstract
Disclosed is an idle gear which comprises a gear body. A first gear and a second gear are arranged on the gear body, the second gear is located outside the first gear, and a yielding groove is arranged between the first gear and the second gear. According to the idle gear, the depth of the yielding groove is smaller than that of yield grooves of existing idle gears, accordingly, the strength of the idle gear is increased, and the service life of the idle gear is prolonged.
Description
Technical field
The utility model relates to a kind of component of machine, relates in particular to a kind of carrier gear.
Background technique
Carrier gear is a kind of widely used component of machine, and its basic structure is to be fixed with two gears that vary in size at an axle.Dodge groove for offering between two different gears of size, it is used for dodging other component in installation process.
But the degree of depth of dodging groove of existing carrier gear is usually darker, and this has reduced the working life of carrier gear so that the intensity of carrier gear descends to some extent.
The model utility content
The purpose of this utility model is to provide a kind of carrier gear, and it is low that it has overcome existing carrier gear intensity, the problem that the life-span is short.
For realizing above-mentioned model utility purpose, a kind of carrier gear of the present utility model, it comprises the gear body, is provided with the first gear and the second gear that is positioned at the first gear outside on the described gear body, is provided with between described the first gear and the second gear and dodges groove.
As further improvement of the utility model, the described degree of depth of dodging groove is 17mm.
As further improvement of the utility model, the center of circle of described the first gear overlaps with the center of circle of described the second gear.
As further improvement of the utility model, described gear body be shaped as a disk.
As further improvement of the utility model, the center of circle of described the first gear overlaps with the center of circle of described discoidal gear body.
As further improvement of the utility model, the center of circle of described the second gear overlaps with the center of circle of described discoidal gear body.
As further improvement of the utility model, the diameter of described the first gear is 110mm.
As further improvement of the utility model, the diameter of described the second gear is 245mm.
As further improvement of the utility model, also offer a through hole on the described gear body.
As further improvement of the utility model, the center of circle of described through hole overlaps with the center of circle of described the first gear and the second gear, and the diameter of described through hole is 60mm.
Compared with prior art, the beneficial effects of the utility model are: the depth as shallow of dodging groove of the existing carrier gear of depth ratio of dodging groove of carrier gear of the present utility model, the intensity that this has increased carrier gear has prolonged working life of carrier gear.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below does to introduce simply to the accompanying drawing of required use in embodiment or the prior art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plan view of carrier gear one embodiment of the present utility model;
Fig. 2 is the sectional view of the A-A direction of carrier gear shown in Figure 1.
Embodiment
Below in conjunction with each mode of execution shown in the drawings the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these mode of execution institute work energy, method or structural equivalent transformation or alternative.
As shown in Figure 1, 2, wherein Fig. 1 is the plan view of carrier gear 100 in the present embodiment; Fig. 2 is the sectional view of the A-A direction of carrier gear 100 shown in Figure 1.
The depth as shallow of dodging groove of the existing carrier gear of depth ratio of dodging groove 103 of the carrier gear 100 in the present embodiment, the intensity that this has increased carrier gear has prolonged working life of carrier gear.
Further, the center of circle of above-mentioned the first gear 101 overlaps with the center of circle of above-mentioned the second gear 102.
Simultaneously, gear body 10 in the present embodiment be shaped as a disk, the center of circle of described the first gear 101 overlaps with the center of circle of described discoidal gear body 10, and correspondingly, the center of circle of stating the second gear 102 also overlaps with the center of circle of described discoidal gear body 10.
Distinguishingly, in the present embodiment, the diameter of described the first gear 101 is 110mm, and the diameter of described the second gear 102 is 245mm.
For carrier gear 100 being set in the rotating shaft (not shown), also offer a through hole 104 on the described gear body 10, the center of circle of described through hole 104 overlaps with the center of circle of described the first gear 101 and the second gear 102.Preferably, the diameter of described through hole 104 is 60mm.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that does not deviate from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, therefore is intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in the scope.Any reference character in the claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
